Температура и время пайки полипропиленовых труб: таблица

Когда собираются водяные коммуникации, состоящие из пластиковых труб, важнейшим параметром становится температура. Она должна иметь определенные значения, позволяющие добиться прочного и надежного соединения.

Сегодня технология разводки трубопроводов из таких материалов предписывает соблюдение определенного температурного режима, а также конкретных временных значений, при выполнении сварочных работ. Если не соблюдать рекомендованные параметры, возможно появление разрыва в узловых местах, значительно ухудшиться движение водяного протока.

Общее влияние температуры при стыковочных работах

Технологический процесс сварки полипропиленовых труб основан на нагреве материала до нужной температуры. В результате пластмасса начинает размягчаться. При соединении деталей происходит диффузия молекул полипропиленовых молекул. Другими словами, в соединение происходит слияние молекул. Когда материал остынет, образуется крайне прочный стыковой узел.

Прочность свариваемых заготовок находится в прямой зависимости от температурного режима. При недостаточном нагреве, не будет происходит процесс диффузии. Молекулы фитинга и свариваемой трубы просто не в состоянии попасть в совмещаемые области. Сварка получится слабой и не сможет выдерживать больших нагрузок. Пара разорвется, нарушится герметичность стыка.

При перегреве конструкция начнет деформироваться. В результате изменится изначальная геометрия. Внутри детали может произойти образование сильного наплыва в виде большого валика. В результате в месте сварки значительно уменьшится диаметр сечения трубопровода.

Для нормальной пайки полипропиленовых труб, необходимо создать нагрев до температуры 255-265 градусов. Процесс нагрева должен учитывать несколько параметров:

• Диаметр детали.
• Температуру помещения.
• Время нагрева.

Практика показала, что время нагрева и диаметр детали находятся в прямой зависимости.

Температура помещения, в котором происходит пайка также оказывает влияние на этот процесс. Когда паяются детали, при извлечении их с «утюга» или другого нагревательного устройства, происходит пауза перед началом муфтовой стыковки. Чтобы компенсировать остывания при невысокой температуре, пп трубы необходимо нагревать немного дольше. Такое добавочное время находится в пределах 2-3 секунд. Подбор происходит эмпирическим путем.

Необходимо помнить, что если нагревать полипропиленовые трубы на нагревательном аппарате с установкой температуры более 270 градусов, произойдет очень сильный нагрев верхнего слоя детали. Сердцевина не получит достаточного прогрева. При стыковке деталей, толщина сварочной пленки получится очень тонкой.

Как сваривать полипропиленовые трубы вручную

Сварочные гильзы устройства подбираются с учетом диаметра деталей. Затем их вставляют в сварочное зеркало и хорошо закрепляют.

Контактные поверхности очищаются от пыли и грязи. Для чистки лучше пользоваться очищающей жидкостью, которую рекомендует изготовитель данного изделия. В такой работе может помочь:

• Хлорэтилен.
• Трихлорэтан.
• Этиловый или Изопропиловый спирт.

Устанавливается определенная температура устройства. Обычно терморезистор должен нагреваться в пределах 250 – 270 градусов. Такое оптимальное значение температуры позволяет достичь правильного соединения.

Когда на термостате наберется нужный тепловой уровень, проверяется температура нагрева сварочного зеркала. Для этого используют специальный термозонд.

Отрезается труба, выдерживая 90 градусов, относительно оси. При необходимости нужно зачистить поверхность и снять фаску. Параметры зачистки, размер глубины фаски берутся из таблицы номер один. Фаску можно снять при зачистке детали или после нее, особым калиброванным инструментом.

Фитинги из полипропилена для раструбной сварки. Глубина зачистки и ширина фаски.

На поверхности трубы отмечается глубина вставки «L1» Берется из таблицы 2. Зачистка должна обязательно соответствовать величине глубины вставки.

Глубина вставки L1(мм): максимальная глубина вставки нагретой трубы в стакан фитинга.

На наружную поверхность трубы и свариваемого фитинга наносится продольная метка. Она дает возможность избежать смещения деталей во время соединения.

Поверхность трубы, а также прикладываемого фитинга, должны быть хорошо очищены от масла или грязи. После достижения нужного нагрева сварочного зеркала, труба, совместно с фитингом устанавливается в специальные гильзы. Фитинги должны быть вставлены до упора, свариваемая труба на полную глубину зачистки. Необходимо немного подождать пока детали нагреются.

Затем они быстро извлекаются и вставляются друг в друга. Глубина вставки фитинга должна равняться длине L1, в соответствии с продольными насечками.

Соединенные детали нужно подержать в зафиксированном положении, определенное время, согласно таблице №3. Затем нужно дать время остыть естественным путем. Нельзя охлаждать их с помощью вентилятора или опускать в холодную воду.

Время нагрева, сварки и охлаждения

Когда поверхность элементов достаточно охладилась необходимо провести их гидравлическое испытание.

Диапазоны температур при контактной сварке.

Изменении давления и температуры в процессе стыковой сварки приводятся на рисунке ниже:

Нюансы выдержки нужного теплового режима

Рассчитывая будущую схему трубопровода, прикиньте, как будет происходить дальнейший монтаж. Необходимо стремиться получить минимальное расстояние между паяльным аппаратом и местом соединения.

Если расчет будет сделан неверно, а место сварки окажется в недоступном месте, приходится разогревать деталь на значительном удалении от места крепления. При этом возникают большие потери тепла, так как приходится заниматься переносом деталей, чтобы выполнить муфтовый стык. В результате таких неучтенных моментов, возникает сильное ослабление шва.

Если сделан ошибочный расчет последовательности монтажа, пайки, может возникнуть ситуация, когда будет нереально состыковать последние детали, так как устройство нагрева просто невозможно установить между деталями. Чтобы увеличить зазор, приходится деформировать определенные участки трубопроводов, позволяющие вставить устройство для пайки. Такая работа  может испортить внешний вид коммуникации. Возможно появление статического напряжения некоторых районов системы.

Очень грубой ошибкой, в результате которой не удается контролировать температуру, является последовательный нагрев заготовок непосредственно перед стыком. Иначе говоря, каждая деталь разогревается отдельно. В результате полностью нарушается температурный режим.

Такой неправильный подход может вызвать сильное остывание детали из-за затраченного времени, необходимой для разогрева. Происходит умышленная потеря тепла. Подобная методика соединения деталей не позволяет правильно выстроить работу и процесс размягчения материала становится непредсказуемым. Пользоваться ею категорически запрещено.

Чтобы осуществлять правильный контроль над температурным режимом, необходимо учитывать несколько критериев:

1.Качество сварочного аппарата для работы с полипропиленовыми изделиями, должно позволять удерживать определенные параметры с минимальной погрешностью.

2.Между сварочным аппаратом и участком соединения, должно быть менее 1.5 метров.

3.Операция должна выполняться в отапливаемом здании.

4.Прежде чем начинать сварочные работы, убедитесь, что температура соединяемых деталей примерно одинаковая.

90000 How to solder polypropylene: tips of the master 90001 90002 Installation work with plastic pipinginclude cutting and joining operations. Due to the technical properties of the material, such tasks are easier to solve than in the case of metal pipes. But the technologies of the same cutting are familiar for the most part only to experienced masters, although it does not cause any special difficulties. In fact, the product of soldering of the material is required, as a result of which it is possible to change the parameters of the design or a separate segment of the pipeline.90003 90002 How to solder polypropylene? As in the case of metal welding, a special apparatus will be required. It can be a small manual thermal cutter, and a massive professional installation. But in both cases the principle of work is the same. 90003 90006 Soldering tools 90007 90002 There are specialized single-format andMultifunctional apparatus-pressovschiki, through which soldering is realized. In this case, this process can be considered both as a cutting method and as a joining operation.The very apparatus in the simplest versions is a small construction with electromechanical stuffing and equipment, formed by metal clips. 90003 90002 How to solder polypropylene using such adevice? From the user, for the most part, only the correct direction of the workpiece is required in accordance with the requirements of the technical process. The principle of the equipment itself is the melt of the pipe. The two parts are heated by contact with metal surfaces, after which any connection operations can be performed with them.In other words, the presser provides two technological functions. Firstly, it is the achievement of a temperature effect for the melting of polypropylene, and secondly, a clear positioning of the edges of the pipes for their correct information. 90003 90006 Preparation for work 90007 90002 The soldering operation of plastic materials is veryis delicate. In the molten state, the plastic is very sensitive and susceptible, so foreign particles can easily penetrate into its structure, the presence of which can further affect the strength properties of the pipeline.Therefore, the blanks themselves and the cutting machine must be thoroughly cleaned, washed and dried. 90003 90002 Additionaldevices that should be at hand during the operation. For example, the question of how to solder polypropylene in hard-to-reach places, often provides for the mention of special hooks and LED flashlights. The hook will allow you to suspend the device if you can not get to the place of work by the whole body and conveniently place the instrument, and the flashlight will provide visibility if other light sources do not penetrate to the workplace.90003 90006 Stages of the operation 90007 90002 The complete soldering process includes 4 stages- this is cutting, heating, joining and cooling. Each stage requires special actions from the operator, which depend on the result to be obtained. 90003 90002 Cutting is not done in every case, but with itsIt can be done neatly with the same exact subsequent connection. The advantages of thermal cutting before mechanical methods include the elimination of the risk of deformation of solid parts of the workpiece.90003 90002 How to solder polypropylene pipes to savethe original form? To do this, it is sufficient to fix the pipe correctly in the clamping rings — then the cutting insert will gently cut and final the spike. The final stage of exposure is the most responsible. When performing it, it is important to properly fix the finished part of the pipe and allow it to cool as long as the standard requires. 90003 90006 Soldering technology 90007 90002 The spike technique should be considered separately.In abbreviated form without cutting this operation is performed more often, therefore the majority of devices have a design optimized specifically for this task. So, the essence of the process is that the two endings of the pipe are installed from opposite sides in the fixing rings. 90003 90002 The operator then activates the thermalimpact. This function can be carried out both by rings and by a cutting incandescent plate. Then immediately connect the two ends of the pipe. 90003 90002 How to solder polypropylene correctly? Unlike the welding machine for metal, plastic soldering tools form a seam without user intervention.Maximum intervention is provided by manual models, in which the user simply presses the lever, which brings together two pipes. This is done smoothly and without excessive pressure — the soft molten plastic must mix, forming a single structural mass at the junction point. 90003 90006 Industrial soldering irons for plastics 90007 90002 In complex and responsible activities, Need help with professional equipment for soldering plastic. Such models are distinguished by the ability to work with large diameter pipes, as well as high intensity of heating.Accordingly, such units are superior to manual models in both dimensions and power of the electric motor. In this case, do not consider the industrial soldering iron as a universal. It is sharpened just for medium and large sizes, but not suitable for small diameters. 90003 90002 How to solder polypropylene on an industrialequipment? The technology and principles of operation are basically the same, but each operation is performed on a separate modular station. One modular unit prepares the pipe with countersinking and facing, the other directly cuts the plastic, the third provides heating, and the fourth one is responsible for positioning the workpiece.90003 90006 Soldering parameters 90007 90002 It has already been said that the quality of the result will bedepend on how accurately and accurately the last stage with cooling was performed. The complexity of this stage lies in the fact that it is necessary to observe the time-keeping regime at several stages. Usually these are two stages — during the heating process and during the final solidification. The time intervals depend on the thickness of the pipe. Also, another factor due to the temperature regime is taken into account.90003 90002 At what temperature is polypropylene to be soldered? Standard hand-operated devices operate at 250-270 ° C. This is enough to bring the usual domestic pipe from plastic to the required state within 15 minutes. As for the ratio of the diameter and the cooling time, the minimum size by 12 mm will require 4 seconds with direct connection, and 120 seconds for final holding. 90003 90002 The maximum diameter of a 50 mm pipe for hand soldering irons requires a 6-second wait while soldering, and the hardening takes place after 240 seconds.90003 90006 Soldering features in hard-to-reach corners 90007 90002 Work in hard-to-reach and difficult areasrequires not only the use of auxiliary equipment (as already mentioned, lanterns and devices for holding the soldering iron). Angular joints provide for a special realization of the technology itself with the use of special consumables. But first of all it is important to remember that cutting is carried out only at a right angle, and after cutting the surface and the ends of the ends must be degreased and be cleaned with a soft abrasive.90003 90002 Now we can move on to another issue — howcount and solder corners. Polypropylene in this case is connected by means of additional nozzles, which introduces corrections in the interval of waiting for the soldering time. That is, to form a corner, a fitting or adapter made of the same polypropylene will be needed. This addition also increases the time spent on the connection site. With a minimum pipe diameter of 12 mm, this interval will be 5-6 seconds, and in the work with a 50 mm billet — about 20 s.90003 90006 Is it possible to solder metal-plastic pipes with polypropylene? 90007 90002 Operations in the course of which the merger takes placeheterogeneous pipes are considered undesirable. Such designs initially lose to similar analogues in reliability, but there are cases when traditional metal plastic must be introduced into the pipeline with polypropylene. Carving in such situations does not help, so you will have to apply to the ration. However, this connection will act only as an auxiliary tool.90003 90002 The installation is realized by means of a flange, into whichEndings of two pipes made of different materials are introduced. Soldering is needed just to prepare a polypropylene pipe for such integration. To do this, using the soldering iron, the end of the plastic pipe is heated, the same fitting is put on it, after which it is possible to proceed with the metal-plastic contour through the flange. 90003 90006 Errors in soldering 90007 90002 Errors for the most part relate to violations intechnique of soldering and selection of unsuitable materials.A common violation of the technology is the deviation from the specified position when connecting pipes. A departure from a straight line per millimeter already means that the connection will be of poor quality. 90003 90002 How to solder polypropylene pipes in order tothere was a breach of the procurement position?

Supply socket method; with the support of the welding machine, pprc pipe and fittings to each other is made through melting and bonding of the source method. Step-by-step; 90003 90002 — The pipe, the pipe in the direction perpendicular to the axis of the pipe with sharp shears will be private so only the cutting process is done properly. 90007 — The welding machine at 260 ° C. It should be heated up. 90007 — Pipes and fittings welding machine by keeping ittirili toward each other from the translator.(Refer to the following resource table by looking at the source and the cooling period) 90007 — The Merge takes place immediately from the source machine to the pipe and fittings. During this process, without compromising the axis of the pipe and fittings must be combined. So, when you put the parts in contact they must be omitted. Precautions against errors which will be held during the application process should be taken very carefully. Otherwise it is likely that the loss of gaps between pipes and fittings and giving rise to a homogeneous structure.Now this give information about the measures that must be considered and taken; 90007 Pipe should be cutted with a pipe cutter and pipe segment in the direction perpendicular to the axis. 90007 — Foiled foil for pprc pipe welding should be peeled while. After becoming made to the source of particles should be peeling foil pipes are not sure. The source of pprc pipe and fittings should not be contaminated. 90007 — Source socket PPRC pipes 260 ° C are carried out. The source of the source machine before the start of 260 ° C.The heated, should be controlled. 90007 — You should be careful with the source of standby time. In the melting process, while it is definitely not pipe and fittings should be returned. 90007 — Parts bevel gear connections should not be used. 90007 — After the flooring installation has finished, the sealing test should be performed. 90003 90241 90048 90049 90050 90245 90031 Outter Diameter 90032 90003 90055 90050 90245 90031 Source Depth (mm) 90032 90003 90055 90050 90245 90031 Heating Time 90032 90031 (sn *) 90032 90003 90055 90050 90245 90031 Max.Idle Time 90032 90031 (sn **) 90032 90003 90055 90050 90245 90031 Source Duration 90032 90031 (sn) 90032 90003 90055 90050 90245 90031 Cooling Time 90032 90031 (dk) 90032 90003 90055 90075 90049 90050 90245 90031 20 90032 90003 90055 90050 90245 14 90003 90055 90050 90245 5 90003 90055 90050 90245 8 90003 90055 90050 90245 4 90003 90055 90050 90245 2 90003 90055 90075 90049 90050 90245 90031 25 90032 90003 90055 90050 90245 15 90003 90055 90050 90245 7 90003 90055 90050 90245 11 90003 90055 90050 90245 4 90003 90055 90050 90245 2 90003 90055 90075 90049 90050 90245 90031 32 90032 90003 90055 90050 90245 17 90003 90055 90050 90245 8 90003 90055 90050 90245 12 90003 90055 90050 90245 6 90003 90055 90050 90245 4 90003 90055 90075 90049 90050 90245 90031 40 90032 90003 90055 90050 90245 18 90003 90055 90050 90245 12 90003 90055 90050 90245 18 90003 90055 90050 90245 6 90003 90055 90050 9 0245 4 90003 90055 90075 90049 90050 90245 90031 50 90032 90003 90055 90050 90245 20 90003 90055 90050 90245 12 90003 90055 90050 90245 18 90003 90055 90050 90245 6 90003 90055 90050 90245 4 90003 90055 90075 90049 90050 90245 90031 63 90032 90003 90055 90050 90245 26 90003 90055 90050 90245 24 90003 90055 90050 90245 36 90003 90055 90050 90245 8 90003 90055 90050 90245 6 90003 90055 90075 90049 90050 90245 90031 75 90032 90003 90055 90050 90245 29 90003 90055 90050 90245 30 90003 90055 90050 90245 45 90003 90055 90050 90245 8 90003 90055 90050 90245 6 90003 90055 90075 90049 90050 90245 90031 90 90032 90003 90055 90050 90245 32 90003 90055 90050 90245 40 90003 90055 90050 90245 60 90003 90055 90050 90245 8 90003 90055 90050 90245 6 90003 90055 90075 90049 90050 90245 90031 110 90032 90003 90055 90050 90245 35 90003 90055 90050 90245 50 90003 90055 90050 90245 75 90003 90055 90050 90245 10 90003 90055 90050 90245 8 90003 90055 90075 90239 90240 90002 *: Ambient temperature + 5C if heating is below 50% of the time in an environment should be increased.90007 **: This time is the elapsed time from the welding of pipe and fittings add sheets until dismounted. 90007 90003 90002 90031 Reducing Elbow 45 ° 90032 90007 90003 90002 90007 90003 90002 90031 C-Curve 90007 90032 90007 92223 90031 Armature Template 90007 90032 90007 90031 Hexagonal Female Threaded TEE 90007 90032 90007 90031 Elbow 45 ° 90007 90032 90007 90031 Elbow 90 ° 90032 90007 90007 90003 90002 90031 Hexagonal External Threaded Elbow 90032 90007 90003 90002 90003 90002 90031 Male Threaded Moving Head union 90007 90032 90003 90002 90031 External Threaded Union 90007 90032 90003 90002 90031 Rotating Head TE 90007 90032 90003 90031 Internal Threaded Elbow 90007 90032 90007 90031 Male Threaded TEE 90007 90032 90007 90031 Female Threaded Moving Head union 90032 90007 90007 90031 Male Threaded Moving Head union 90032 90007 90007 92223 90002 • For All types of projects, and product inquiries, you can visit our official website.For Technical information and all types of Request you can mail us. 92223 90003 .90000 Polypropylene pipes: technical characteristics, application 90001 90002 What are polypropylene pipes?
