Part3: GB/T18742.3-2002 (for fittings)

Specification for the products

1. Hygienic, nontoxic, it's belongs to "health and Environmental Protection" green building materials, supply for the hot water supply systems, and can be used directly as pure water and drink water pipes.

2. Heat-resistant, durable, can be used for many years. The usually work temperature is 70ꇦ, and it can be work at 100ꇦ for short time. For example: the PP-RS2 system's pipe, it can be used for at least 50 years if at the condition that the work temperature is 70ꇦ, and work pressure is 1.0MPa. If the work temperature is 20ꇦ, it can be used for at least 100 years.

3. Heat protection and economize on energy, the coefficient of heat condition is only the 1/200 of the metal pipe, it is the best material for the hot water supply system for the heat protection and economize on energy.

4. Rust proof, without accumulated filth, can be avoid the "Second pollution" caused by rust water filth of the zincification pipe.

5. Light in weight, the specific gravity is only the 12% of the metal pipe, the intensity of pressure-proof can be above 50Kg/cm², with good teacity and high impact proof.

Good look at the appearance, smooth both the inner and outer wall, low water flow resistance.
