pvc-u double-wall corrugated pipe is a high-density polyethylene as the main raw material, respectively, by the inner and outer extrusion, disposable molding, wall smooth trapezoidal wall corrugated concrete drain, there is sandwiched between the inner and outer walls of the hollow walls plastic pipe. pvc-u double-wall corrugated pipe has high ring stiffness, high strength, light weight, sound damping, high UV stability, long life, good flexibility, impact strength and higher pressure several advantages. Can be laid in a poor section of geology, and sealing, and construction faster. pvc-u double-wall corrugated pipe has excellent insulation, fire-retardant and impact resistance, and corrosion resistance, smooth wall, hollow wall corrugated drainage pipes and corrugated structure, making pvc-u double-wall corrugated pipe quality light, ring stiffness high, flared end, socket type connection, rubber ring seal, easy to install and maintain. pvc-u double-wall corrugated pipe application areas: 1, municipal engineering, residential quarters underground rainwater, sewage; 2, sewage treatment plants, landfill drainage conveyance; 3, farmland irrigation water, drainage; 4, chisel into the project into the wall of the tube (perforated wall bellows); 5, highway embedded pipes; 6, mine drainage, ventilation ducts of the building. Building Materials Co., Ltd., Dongguan City unimpeded factory direct, wholesale and retail all kinds of water supply to the water pipes, drainage outfall drainage slope, cable protection sleeve and various pe fittings and fused pipe, pvc series which include: pvc-u drains, pvc -u to the water pipes, pvc-u cable pipe, pvc-u corrugated drainage pipe, pvc-c cable pipe, pvc-c to the water pipes, pvc-m water supply etc; pe tube hepe series of pipeline include: hdpe double wall corrugated pipe, hdpe corrugated steel pipe, hdpe hollow wall winding pipe, hdpe pipe communication cables, etc., welcome new and old customers to inquire. Advantages drainage layer with the layer siphon siphon drainage system to solve the problem drainage price, drainage branch pipe located in this floor, never inconvenience 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, not (minus 40 degrees Celsius) or burst decomposition at low temperatures; 2. Pipe with heat, abrasion and acid corrosion; for dishwasher and washing machine effluents good corrosion resistance; smooth inner surface of the pipe 3.PE avoid fouling deposition; 4. high quality polyethylene ensure system performance and long service life; 5.PE pipe connections, reliable, safe and reliable system no leakage; 6. widely polyethylene (hdpe) diameter pipe specifications, pipe fittings and diverse models for a variety of facilities to meet the project needs.
