Light weight with only 0.95 grams/cm 2.Weigh only 1/5 of HDPE pipes of the same size. High flexibility. Can be bent as much as 25-40 times of the pipe diameters, thus reducing unnecessary pipe joints. Rust proof and high resistance to damaged chemicals
SECTION 1403 The design pressure of the pipe shall be defined in accordance with ASTM D 3035 and F 714. The pipe shall have a controlled outside diameter and shall be produced to an SDR/DR ratio no larger than (B) HDPE Fittings. The fittings shall be
Standard laying lengths of HDPE pressure water pipe is 40/50 foot lengths. Pipe sizes under 6” may be coiled at continuous longer lengths upon request. Marking: The standard markings printed on JMM pipes generally consist of the JMM logo, nominal size
Chapter 2 Inspections, Tests and Safety Considerations 17 Figure 1 Typical Truckload of Coiled, Silo-Pack Pipe (40’ Trailer) PE pipe is produced in coils or in straight lengths and shipped on fl atbed trailers. Coils are typically limited to 6-inch and smaller sizes.
Every pipe size exceeds HDPE’s bending stress limits of 3,000 psi (Figure 2) at deflection levels of 5% (1/3 less than the CPPA’s suggested maximum allowable deflection of 7.5%). HDPE Pipe’s ability to support a load is typically assessed by measuring the 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
Pipe Inspection – Hydro Test, NDT, Visual and Dimension To ensure product quality, during and after the production certain pipe inspection and non-destructive testing are performed on the body & weld of the pipe. These pipe inspection will check whether any Puhui Pipe manufacturer in China

rupture test and the hydrostatic pressure test (ISO 1167). The long term creep rupture tests involve preparing a tensile test specimen or using a full pipe section and in both cases an initial axial stress of 5.4-5.5MPa is generated
ISO 11414 “Plastics pipes and fittings – Preparation of polyethylene (PE) pipe/pipe or pipe/fitting test piece asselies by butt fusion.” ISO 13953 “Polyethylene (PE) pipes and fittings – Determination of the tensile strength and failure mode of test pieces from a butt-fused joint.”
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
4.1 This test method is designed to impart tensile impact energy to a butt fused plastic pipe specimen, record the energy to fail the specimen and plot the load over time curve of the tensile test. Energy recorded at yield and rupture and the rupture mode (brittle or ductile) are used as criteria in the evaluation of the butt fusion joint.

HDPE pipe can be cold bent to a minimum bending radius of R = α x OD, where R is the minimum bend radius, OD is the pipe’s outside diameter, and α is the minimum bend ratio. The minimum bend ratios shown below are for a long-term appliion based on the pipe DR.
This page covers the destructive bent test required to become a certified welder. This section covers how to mark a pipe for bend test coupons, cutting of weld coupons and a bent test conducted by a Certified Welding Inspector. Finally passing the AWS B2.1 6G
High Density Polyethylene (HDPE) Jacketed System is designed for piping systems above or below ground suitable for inside or outside appliions. High quality polyurethane foam insulation coined with a durable watertight jacket supplied in 20'' or 40'' lengths, means an economical, high-quality system.
