PP-R pipes

Product information

1. Resistance to chemical corrosion:

Dat Hoa PPR pipe products are resistant to most chemicals such as: sulphate, chloride, nitrate ..., common chemicals in water supply systems and well water sources. PP-R products do not oxidize in air, especially moist air; Withstand PH environment from 1 to 14.

2. Precipitation:

The inner surface of the tube is very smooth, the roughness reaches 0.007mm. On the other hand, due to the smoothness of the tube, it completely prevents the deposition of lime or moss on the pipe wall

3. Connecting pipes:

The PP-R pipe connection is welded in connection with the temperature of 260 ⁰C so the welding technique does not require any complexity. Manual welding equipment, from 4-40 seconds and the tube can withstand maximum pressure after 2-10 minutes (depending on the diameter of the pipe). The joint achieves mechanical strength, temperature, pressure, does not use chemicals, so it does not poison water. The joints withstand pressure of 4kg/cm³, meeting the requirements for domestic water supply pipes.
