HDPE Steel belt reinforced spiral bellows
The steel belt reinforced polyethylene (PE) spiral corrugated pipe is a new type of bellows with high-density polyethylene as the basic material, the outer layer is spirally wound in the wall layer, and the steel plate is reinforced with hollow ribs. In addition to the corrosion resistance, smooth inner wall and low flow resistance of ordinary plastic pipes, it has a steel ring as a hollow surrounding structure of the reinforcement, so it also has a ring degree of more than 12.5KN/m2 (spiral winding). Hollow wall polyethylene can only reach 8KN/m2 ring steel) and high strength and toughness, light weight (40% lighter than spiral wound hollow wall polyethylene pipe), impact resistance, not easy to break, no leakage, etc. Features, so it is widely used in drainage, sewage, agricultural irrigation, coal mine ventilation, chemical, communications cable sheathing and other fields. Because of its light weight and convenient transportation and installation, it reduces the labor intensity of construction workers and reduces the cost of the project. It is an ideal substitute for concrete pipes and traditional drainage plastic pipes.
