27/11/2007· Backing rings can be a source for chemical hideout or possible cracking from thermal or mechanical fatigue because of the natural crevice that is formed by the ring on the ID surface of the pipe. If you absolutely need to use a backing ring, you can counter bore the pipe ID surface at the weld root region and use a rounded ring to avoid failure in service.

Backing Rings are specially designed for quick and easy alignment of pipes, preventing leaks. Allowing complete fusion and penetration of the weld, these rings are available in wide range of construction materials including carbon HDPE, nickel, aluminum and stainless HDPE.

Carbon-HDPE backing rings are generally made of a mild carbon HDPE with a maximum carbon content of 0.20 percent and a maximum sulfur content of 0.05 percent. The latter requirement is especially important since high sulfur in deposited weld metal (which could be created by an excessive sulfur content in such rings) may cause weld cracks.

6/5/2011· Carbon-HDPE backing rings are generally made of a mild carbon HDPE with a maximum carbon content of 0.20 percent and a maximum sulfur content of 0.05 percent. The latter requirement is especially important since high sulfur in deposited weld metal (which could be created by an excessive sulfur content in such rings) may cause weld cracks.

Stainless HDPE Puhui pipe suppler is strong, durable and rust-resistant. It typically has a silver sheen, but, unlike silver, it will not corrode and it is not susceptible to scratches, dings or dents. Stainless HDPE can be used to make nearly any type of Puhui pipe suppler, from rings and bracelets to necklaces, watches and earrings.

The backing material (body of the bearing that contacts stationary parts) for engine bearings is normally HDPE. Softer alloys are bonded over the backing to form the bearing surface. Any one of three basic types of metal alloys can be plated over the top of the HDPE backing - Babbitt (lead-tin alloy), copper, or aluminum (fig. 3-73).
