PE water supply pipe connection

Welding steps of PE water supply pipe PE water supply pipe is a special polyethylene as raw material through a plastic extruder extrusion molding, used in urban water supply network, irrigation water diversion engineering and agricultural sprinkler irrigation engineering, especially suitable for acid and alkali resistant, corrosion resistant plastic pipe environment. As the PE pipe is connected by hot melt and electric melt, the integration of the interface and the pipe is realized, and the circumferential stress and axial impact stress generated by the pressure can be effectively resisted. Moreover, the PE pipe does not add heavy metal salt stabilizer, the material does not scale, does not breed bacteria, and avoids secondary pollution of drinking water. The welding of PE water supply pipe can be divided into the following steps, which are very important. Everyone must pay attention.

Product Description

Welding steps of PE water supply pipe PE water supply pipe is a special polyethylene as raw material through a plastic extruder extrusion molding, used in urban water supply network, irrigation water diversion engineering and agricultural sprinkler irrigation engineering, especially suitable for acid and alkali resistant, corrosion resistant plastic pipe environment. As the PE pipe is connected by hot melt and electric melt, the integration of the interface and the pipe is realized, and the circumferential stress and axial impact stress generated by the pressure can be effectively resisted. Moreover, the PE pipe does not add heavy metal salt stabilizer, the material does not scale, does not breed bacteria, and avoids secondary pollution of drinking water. The welding of PE water supply pipe can be divided into the following steps, which are very important. Everyone must pay attention to it.(1) when welding PE water supply pipes, center the axes of the two pipes, and spot weld and fix the ends of the two pipes first.(2) when welding PE water supply pipes and flange plates, insert the water supply pipes into the flange plate first, use angle ruler to find the alignment after spot welding, and then weld after leveling. The flange plate shall be welded on both sides, and the inner side shall not protrude the closing surface of the flange plate.(3) When the wall thickness of PE water supply pipe is above 5mm, the groove shall be cut to ensure full penetration. Gas welding cutting or beveling machine can be used for groove forming, but the slag and iron oxide should be removed and polished with a file until the metal light is exposed. (4) When cutting the steel pipe, the cutting surface should be perpendicular to the center line of the pipe to ensure the concentricity of the pipe after welding.(5) The flange should be perpendicular to the center line of the pipe, the surface should be parallel to each other, and the flange gasket should not protrude into the pipe, the bolt specification of the connecting flange shall be matched with the flange, and the length of the screw protruding nut shall not be greater than 1/2 of the screw diameter.(6) When welding the water supply pipe, the pipe joint shall be cleaned of floating rust, dirt and grease.(7) The flange gasket shall be selected according to the drawings and specifications. The cold water system adopts rubber gasket and the hot water system adopts asbestos rubber gasket.

HDPE water supply pipe:
1. Reliable connection: PE pipe systems are connected by electric melting, and the strength of the joint is higher than that of the pipe body.
2, good low temperature impact resistance: PE pipe low temperature embrittlement temperature is very low, can be used safely in the low temperature range. During winter construction, the material will not crack due to its good impact resistance.
3. Good stress cracking resistance: PE pipe has low notch sensitivity, high shear strength and excellent scratch resistance, and its environmental stress cracking resistance is also very prominent.
4, good chemical corrosion resistance: PE pipe can resist the corrosion of a variety of chemical media, the chemical substances in the soil will not cause any degradation of the pipeline. Polyethylene is an electrical insulator, so it does not decay, rust or electrochemical corrosion; in addition, it does not promote algae, bacteria or fungi growth.
5. Aging resistance and long service life: polyethylene pipes containing 2-2.5% evenly distributed carbon black can be stored or used outdoors for 50 years without being damaged by ultraviolet radiation.
6, good wear resistance: PE pipe and steel pipe wear resistance comparison test shows that the wear resistance of PE pipe is 4 times that of steel pipe. In the field of mud transportation, compared with steel pipes, PE pipes have better wear resistance, which means that PE pipes have a longer service life and better economy.
7, good flexibility: the flexibility of PE pipe makes it easy to bend, engineering can bypass obstacles by changing the way of pipe direction, in many occasions, the flexibility of the pipe can reduce the amount of pipe fittings and reduce installation costs.
8. Low water flow resistance: PE pipe has a smooth inner surface, which has a higher conveying capacity than traditional pipe, and also reduces the pressure loss of the pipeline and the energy consumption of water delivery.
9, easy to handle PE pipe than concrete pipe, galvanized pipe and steel pipe lighter, it is easy to handle and install, lower manpower and equipment requirements, means that the installation cost of the project is greatly reduced.
