General Guidelines for Squeezing Off Polyethylene Pipe gas, multiphase fluids, non- potable oilfield water or potable water in polyethylene pipe by compressing the pipe between parallel bars until the inside surfaces make contact. The flexibility and toughness of polyethylene pipes allow the pipe to recover from a properly made squeeze-off without a measurable loss in service life. When properly HDPE Natural Gas Pipe - WL Plastics - Natural Gas DistributionWL Plastics specializes in the manufacture of high-density polyethylene (HDPE) pipe for natural gas distribution systems. This material finds use in a wide range of applications and industrial processes. Where medium-density polyethylene (MDPE) natural gas pipe has been the standard for this industry in the past, HDPE pipe is the future and the ideal piping

The history of PE pipe Hart Energy

The first installation of PE gas distribution pipe took place in Caney, Kansas, in 1959, with pipe manufactured by Phillips Petroleum. By the mid-1960s, utilities began to make the transition from steel and cast iron to PE pipe. DuPont and Phillips Petroleum were two of the early main developers of PE pipe.

Whats the Difference Between ABS and PVC Pipe?

ABS Pipes vs. PVC Pipes. Many of the key differences between Acrylonitrile Butadiene Styrene (ABS) and Poly Vinyl Chloride (PVC) are either minor or situational, but theres one difference likely to stand out to many homeowners:ABS pipe is made with BPA, and PVC pipe is not. BPA, or Bisphenol A, is a chemical commonly used to harden plastic Underground Gas Polyethylene Piping SystemMetallic pipe installed underground requires additional and costly materials to protect the pipe. Polyethylene gas piping systems are specifically engineered and certified for the underground environment.
