Scope：

This series of fittings can match the standard ISO 1452

Gasketed pipe is required by many municipalities for public sewage systems，It is typically installed underground.

Specification：

Pipe and fittings shall be manufactured from virgid PVC(polyvinyl chloride) vinyl compounds.

DIN gaskets are designed specifically for DIN fittings. 

Fields of application：

Piping networks for water supply in building.

Piping networks for piping system in water treatment plant.

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

2. Good aging resistance, the normal service life can reach more than 50 years.

3. The pipeline has excellent corrosion resistance to inorganic acid, alkali and salt, which is suitable for industrial sewage discharge and transportation.

4. Small friction coefficient, smooth water flow, not easy to plug, less maintenance work.

5. The material has high oxygen index and self-extinguishing property.

6. The linear expansion coefficient of the pipeline is small, 0.07mm/℃, and the deformation affected by temperature is small. The thermal conductivity and elastic modulus are small, and the freezing resistance is better than that of cast iron drainpipe.

7. The connection of pipes and fittings can be bonded with simple construction method, convenient operation and high installation efficiency.

8. With good water tightness: the installation of PVC-U pipe has good water tightness, whether it is connected by adhesive or rubber ring.
