HDPE PE 100 pipe is based on a design stress value of 8.0MPa, which results in an even thinner pipe wall thickness than PE 80 pipe due to the higher grade of material.
Puhui HDPE pipeline’s HDPE pipe for water and sewer is manufactured for excellent performance and a long life expectancy. Its butt-fused joints eliminate potential leak points, common at 10 to 20 feet with UPVC pipe, for a zero leak rate. Highly resistant to corrosion and

For pipe constructed from HDPE, the bend radius limitation of the drill rods is sufficiently large to be compatible with that of the product pipe. Figure 3 shows a typical plot for the required setback distance of the drill rig corresponding to the distances shown in Figure 2, and also indies the minimum possible depth for a level trajectory.
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

Example; the minimum radius of bend for placing a 500mm, SDR 11 pipe is; (500 x 15) mm = 7.5m It should be noted that joints should not be included in bends of the minimum radius in order to avoid high local stresses at fittings or butt fusion joints.

18/8/2004· Cold field bend radius of HDPE is function of DR and OD. MINIMUM Bend radius for common drs are as follows: DR9 or thicker = 20 times od DR 9 to DR13.5 = 25 times od DR 13.5 to DR 21 = 27 times od greater than DR 21 = 100 times od ie. 8 in. PE100 DR 11
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.
For curves of smaller radius, post formed bends or moulded fittings shall be used. The allowable radius of curvature depends on the temperature of the pipe and the SDR. The following table gives recommended minimum bending radii for pipes at 20 C.

HDPE pipe''s durability is demonstrated by this highway cross drain installed in 1981 near an abandoned strip mine. The metal pipe used prior to this time had to be replaced every few years due to the highly acidic (pH range was between 2.5 to 4.0) and abrasive Puhui Pipe manufacturer in China

By virtue of its flexibility, an HDPE pipe automatically accommodates itself within its minimum radius limits to the configuration of the terrain. Submarine pipelines are used as pressure lines e.g. drinking water lines, gravity flow lines and electrical cable conduits.
