National standard carat tube, thermal winding forming structural wall tube

The national standard carat pipe, that is, the high-density polyethylene (HDPE) wound structural wall pipe produced according to GB/T 19472.2, its core process is hot winding molding. The process will melt polyethylene flat strip material in the hot state spiral wound on the core mold, synchronous reinforcing ribs wound and welded to form a corrugated outer wall, smooth inner wall of the structural wall pipe. The whole process is completed continuously, the pipe integrity is strong, no internal stress. Hot winding molding endows the pipe with outstanding ring stiffness and resistance to external pressure, and higher bearing capacity under the same weight. The pipe is connected by socket electric fusion or heat shrinkable tape, and the interface is sealed reliably, which can effectively prevent leakage. Polyethylene material is resistant to acid and alkali corrosion, and has a long design life, smooth inner wall and small conveying resistance. Such pipes are widely used in municipal rainwater and sewage discharge, industrial wastewater transportation and culvert drainage projects. Its flexible connection can adapt to a certain foundation displacement, good seismic resistance, fast construction, and good comprehensive economy. When purchasing, you should look for the national standard products, and check the test reports of key indicators such as ring stiffness and ring flexibility.
