Gas & Oil Field Pipe - Recommended Use

The Plastic Pipe Institute has issued the following “Use Recommendation” for Polyethylene Piping systems for LPG and its major component, propane gas. (Technical Report PPI-TR22-July 1974)

The information collected indicates that polyethylene plastic piping is satisfactory for transporting LPG and its major component, propane gas. This information also indicates that pressure design parameters based on propane gas should be adequate and reasonable. However, until more information is available, these recommendations cover only commercial propane vapor in detail. These use recommendations cover polyethylene plastic pipe for commercial propane gas systems that serve 10 or more customers or for systems, any portion of which is located in a public place, such as a highway.

The polyethylene pipe, tubing and fittings should be only those specific types designated as PE-2708 or PE-4710 and meeting the appropriate requirements of ASTM D2513.
A long-term hydrostatic strength (design basis) of 1000 PSI should be used in the design of polyethylene piping systems for commercial propane gas distribution at pipe temperatures of 73°F or lower. The long-term hydrostatic strength measurements should be made in accordance with ASTM D2837.
Polyethylene piping should be used only in underground commercial propane gas distribution systems designed to operate at internal pressures and temperatures such that condensation will not occur.
