PVC pipe drain is sanitary grade PVC resin as the main raw material, adding the right amount of stabilizers, lubricants, fillers, toner by plastic extrusion molding and injection molding machine injection molding, through the cooling , Curing, setting, testing, packaging and other processes to complete the pipe, pipe production.

PVC drainage pipe is an alternative to traditional drainage pipes and has better physical and chemical properties.It has smooth inner wall and less frictional resistance than conventional drainage materials so that the horizontal pipe has a smaller installation slope and can improve the indoor ceiling of the building.At the same time, PVC drainage pipe lighter, one-fifth of the cast iron pipe, easy to transport and operation; Adopt the glue connection, easy installation and maintenance; The price is lower than the conventional drainage pipe, greatly reducing the project cost; Corrosion resistance, Waste water and rainwater pipe system is generally used.In addition, PVC drainage pipes are widely used to save steel, to ease the situation of China's steel shortage is of great significance.Compared with cast iron pipe, steel pipe, PVC-U pipes exist Low pressure and weak impact resistance.In addition, although PVC-U drainage pipe is a flame-retardant material, there is a possibility that the fire spread upward along the drainage riser in the indoor pipe.

1. Excellent pipe surface hardness and tensile strength, high pipe safety factor.

2. Anti-aging is good, the normal service life of up to 50 years.

3. Pipeline of inorganic acids, alkalis, salt, excellent corrosion resistance, suitable for industrial wastewater discharge and transport.

4 pipeline friction coefficient is small, smooth flow, easy to block, less maintenance workload.

5. Material oxygen index is high, with self-extinguishing.

6. Pipeline coefficient of linear expansion is small, 0.07mm / ℃, small deformation due to temperature. Thermal conductivity and elastic modulus of small, compared with cast iron drainage pipe antifreeze performance.

7. Pipe, pipe fittings can be used to connect the bond, the construction method is simple, easy to operate, installation work efficiency.

8. Has a good water tightness: PVC-U pipe installation, regardless of the use of adhesive or rubber ring connections, have good water tightness.
