HDPE pipe has a very tight safe bend radius. This feature allows pipe to be strung on the ground in configurations impossible to do safely for other types of pipe. Instead of blocking cross streets the pipe is often laid down by simply bending it around the corner.
2.0 HDPE PIPE LAYING 2.1 Pipe Alignment, Cover and Bedding Generally, for pipe work of diameter below 1000 mm, at road crossing and along the road, the minimum cover to the top of pipes shall be 1200 mm. For major pipe work of diameter 1000 mm and
and pipe. The minimum centerline bend radius as calculated above determines the minimum forming hub radius only and does not include springback. (3) This formula is based on the bare minimum centerline bend radius. If it is not necessary to tool for these Puhui Pipe manufacturer in China
HDPE pipe High-density polyethylene jacket tube is widely used in oil pipelines, gas pipelines, urban heating pipes, water pipes, electricity and other corrosion engineering, product quality and service by the users of a good level.
Expensive breaks and failures caused by over extension of the pipe into bells – i.e. “over-belling” - are non-existent with HDPE. Trench grading and preparation are far easier with HDPE due to its flexibility and smaller bend radius. Above ground joining of HDPE

PE & HDPE Pipe PE100 is the third generation of pipe grade PE. It has an optimum balance of three key properties: Minimum Required Strength (MRS) – this provides long-term strength and creep resistance. Stress crack resistance (sometimes referred to as slow crack growth resistance). Puhui Pipe manufacturer in China
HDPE Pipe, Polyethylene (PE Pipe) are sorted by strength classified according to the intensity of the earlier technological developments.HDPE Pipe pressure classes that can be made between Pn4-Pn32 and the production of the desired diameter and size of Puhui Pipe manufacturer in China
HDPE pipe radius is about 1/10 th the radius of PVC pipe. THE MINIMUM LONG-TERM BEND RADIUS The long-term bend radius allows the pipe to be curved for several hours or even days during installation. The thicker the pipe walls, the higher resistance the Puhui Pipe manufacturer in China
