Summary of retrofitting techniques and analysis of air leakage electrofusion fittings and the product market output value is highly competitive

Consider beforehand that the object of transformation is the water heater of gas or electricity, to avoid temporary replacement of the type of pe electrolytic dissolving pipe, resulting in repeated transformation of the water circuit.

1, if you close the excess leakage, Taizhou PE water supply pipe fittings must plug the gap between the pe electrolytic dissolving pipe parts and the floor drain to prevent the backflow of water.

2, hot water on the watercourse should be 2 cm higher than the wall, laying wall tiles, but also in the tiler laying wall tiles. It should be ensured that the wall tiles are at the same level as the water pipe opening. In addition, if the size of our pe electric fusion pipe parts are not appropriate, then later installation of electric water heaters, separate faucets, etc., other pipes of the Cabos, because it is possible to buy the inner line and other connection parts before completing the installation, we must pay attention to these professional details in the remodelling. If the pipe tube leaks air, Cixi PE water supply pipe fittings maybe people will have different moods, but if someone does not know how to do it will there be any problem?

PE electrofusion pipe when the air leaks, different people may have different moods, there is a person does not know what to do is good? And very nervous, afraid of what happens to the problem, we should do in the end how to do it? Solution

1, the solution of not becoming a shaft: use a special jig.

2, one of the ways to solve the welding: before welding must be cleaned up the oxidation layer of the outer wall of the pipe welded; otherwise, the welding is not reliable. Due to the relatively high temperature requirements for the melting of the oxide layer, not suitable for fusion with PE molten material, especially for small-diameter pipe components, small-diameter pipe components, the specified heating time is relatively short electro-molten tube body, the resistance wire in a short period of time to put out less heat, in the premise that the oxide layer is not clean, it is easy to produce false contact. Although it may be qualified in the process of pressure, but due to the filling pressure, road vibration, unevenness and settlement and other reasons, the false welded parts are easy to fall off, Yuyao PE water supply pipe fittings therefore leakage in the operation, causing accidents. Clean standard is caused by the yellow marking beautifully with welding grade.

3, solve the method of false welding 2: welding machine to check the output voltage, the output voltage is required to 39.5v ± 0.5V, output voltage is lower than 39V, due to the resistance line of the specified time of the heat generation is less, connecting parts of the PE material can not be effective and fully fused, so false welding should occur.

4, one of the ways to solve the internal hole: if the control output voltage is not higher than 40V, the welding time control can not be implemented in accordance with the instructions, both of the above two points of loss of control can produce overheating of the resistance wire, the temperature of 240?When exceeded, the PE material evaporates, the formation of an internal cavity, cooling the formation of holes.
