Welcome to inquire! Contact: Fengjing Li. Definition: polyethylene resin-based Jiuzhou pe bellows, extrusion molding process for no internal pressure thermoplastic pipe collectively. Features: 1) Anti relatively strong external pressure. 2) thin wall, low construction cost. Light weight, convenient construction. 3) wear resistance coefficient is small, large flow. Good low temperature pe bellows, impact resistance. 4) good chemical stability. Long service life. UV rays from the sun under the conditions of use life pe bellows drainage, HDPE double wall corrugated pipe of up to 50 years. 5) excellent wear resistance. ⑻ appropriate deflection. HDPE double wall corrugated pipe axially slight deflection, uneven settlement to some extent affected by the ground; you can not directly laying pipe in a trench slightly not straight. Melt temperature Xiong Wang Thai Plastic Products Factory ④ forming tube control instability, high or low melt temperatures are easy to make after the tube shape crisp, pay attention to the temperature of the melt plastics do not lower the temperature fluctuated the difference is too large. Inner and outer walls (4) double-wall corrugated pipe ① poor adhesion to the mold within the melt temperature is low, should increase the mold temperature. ② raw lubricant is too large than copies, should be appropriately reduced amount of lubricant. ③ tube cooling too quickly, the two weld material is not strong, attention to proper tube slow the cooling rate. The inner wall (5) pipe with vertical scratches Xiong Wang Thai Plastic Products Factory
