The main characteristics of PVC-U pipes an environmentally friendly, does not affect the water quality: the dissolution tests confirmed not affect water quality, suitable for large scale applications. 2, the mechanical strength: pipe has good pressure resistance, impact resistance and tensile strength properties. 3, light weight excellent corrosion resistance: less density, easy handling, loading and unloading, and construction. Has excellent resistance to acid, alkali, corrosion resistance, for the purposes of the chemical industries. 4, fluid resistance: pipe wall is smooth, its roughness coefficient of only 0.009 drainage slope, fluid resistance, effectively improve the water pipe network conditions, reducing system operating costs. 5, simple construction and low cost: pipeline construction to connect quickly and easily drainage pipe, low construction project costs; low price, and transport, easy construction, long life, and therefore the overall cost low. Advantages drainage layer with the layer siphon siphon drainage system to solve this problem, drainage branch pipe located in this floor, never inconvenience drains to the downstairs tenants, property relations can be clearly recognized. With siphon drainage layer There are several ways to install a descending plate:? Which uses the bathroom floor (or partial floor) sank two ways, Wall row: hidden disadvantages to pipeline installation system as the main feature of the way three-cushion type: finger elevate the way bathroom floor with floor siphon drainage pipe: HDPE drainage pipe siphon siphon drainage pipes hdpe features: 1. Pipe has a strong impact resistance of concrete drainage pipes, not (minus 40 degrees Celsius) or burst decomposition at low temperatures; 2. pipe with heat, wear and acid corrosion; for dishwasher and washing machine effluents good corrosion resistance; smooth inner surface of the pipe 3.PE avoid fouling deposition; 4. Poly high performance and long life guarantee system of ethylene; 5.PE pipe connections, reliable, safe and reliable system no leakage; 6. polyethylene (hdpe) pipe diameter specification wide variety of pipe fittings models for a variety of facilities to meet engineering needs.
