I''m looking for a bit of advice from anyone with experience fusing HDPE pipe. We''re about to install a pumping system with a substantial vertical drop, and have purchased 10" HDPE pipe with SDR ratings of 17, 11, and 9. The plan is Puhui Pipe manufacturer in China
The bend test uses a coupon that is bent in three point bending to a specified angle. The outside of the bend is extensively plastically deformed so that any defects in, or erittlement of, the material will be revealed by the premature failure of the coupon.

Pipe Hangers and Conduit Hangers Selection Guide Pipe hangers and pipe supports are used to support hanging pipe.They include clevis hangers, beam clamps, pipe clamps, brackets, and pipe straps. A band hanger is a type of pipe hanger that supports the pipe on a continuous strap of metal whose ends are joined at the top by a supporting rod.
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
Pipe joining systems vary widely across the range of pipe systems used in the United States. In general, pipe joints are designed to match the performance and testing standards required for the appliion in which they are to be Puhui Pipe manufacturer in China
Pipe and fitting surfaces where tools and equipment are fitted must be clean and dry. Use clean , dry, non- synthetic (cotton) cloths or paper towels to remove dirt, snow, water and other contaminants.

Bent strap test samples may be bent back on themselves or twisted through 180 degrees. If the sample breaks at the loion of the fusion, this is an indiion that the appropriate conditions were not established to permit satisfactory fusion to occur.
The bent strap test specimen is prepared by making a trial butt fusion, usually the first fusion of the day, and allowing it to cool to aient temperature. A test strap that is at least 6” or 15 pipe wall thicknesses long on each side
Nick-break test is a variant intended to test the soundness of a weld. From a groove welded test panel, a section of say 50 mm (2") width is removed. Two saw cuts are machined before bending, for a depth of about 6 mm (1/4"), at both the width sides of the specimen section, along the whole depth of the weld.
