Risong HDPE pipes for water is made according to GB13663-2000 and ISO4427:1996 standards. The specific introduction of our HDPE pipes as follows:
■ The HDPE pipes made by Risong are honored with various certifications issued by quality inspection office and health authority.
■ The HDPE pipes are made of superior quality materials PE100 with higher pressure strength and sound anti-breakage performance.
■ The colors available are black & blue, with standard length is 5.8 meters and 11.8 meters. The pipes 'outer diameter less than 63mm would be packed in roll, it would be decided at clients 'requests.
■ There are 5 SDR-PN grades for Risong HDPE pipes, which are: SDR26-PN6 bars, SDR21-PN8 bars, SDR17-PN10 bars, SDR13.6-PN12.5 bars, SDR11-PN16 bars.
■ To connect to the HDPE pipes, Risong can also provide various HDPE fittings, which include: socket fusion fittings, butt fusion fittings, electro fusion fittings.
Risong HDPE pipes have following advantages:
Nontoxic: HDPE material is nontoxic, tasteless. It belongs to a kind of green building material, never scaling, which can effectively improve the water quality.
Corrosion resistance: high resistance to attach from various types of chemicals, no electrochemical corrosion.
No leakage: The HDPE pipes are connected in the ways of butt fusion, socket fusion and electrofusion. The strength of joint point is higher than pipe itself.
Higher flow capacity: The smooth inner wall is easy for pipeline transportation.
Convenient for construction and installation: HDPE pipes can be installed in a variety of trenchless ways.
Longevity: The HDPE piping system can be worked at 50 years under pressure rating.
Recyclable and evvironment-friendly.
Material: Top quality virgin PE100 raw materials from China.
Color available: blue color, black color with 4 blue strips.
Related reference: GB13663-2000 and ISO4427:1996 standards.
Packing length: 5.8 meters or 11.8 meters as standard length. Pipe diameter less than 63mm can also be packed in rolls.
Remark: O.D.means outer diameter of HDPE pipes, W.T.means wall thickness of pipes.
Risong can also provide various HDPE pipe fittings & welding machines.
