For years, most pipes were made from Grade B steel, which has a minimum yield strength of 35,000 psi. Construction of high-pressure, large-diameter, cross-country transmission lines created a need for high-strength field-weldable steel that would allow a substantial savings in steel tonnage....

• When using a wheel-type pipe cutter, be sure the cutter wheel does not thread down the pipe – cut off all partial cuts before fusion. • On larger pipes, toe-in may need to be removed before fusion 2. Chamfer. For all pipe and tubing sizes, chamfer the end to remove the ...
If we compare the wall thicknesses required by ASME B31.3 and ASME B31.8 for piping in a compressor station, it can be seen that the ASME B31.3 Code is more conservative than the ASME B31.8 Code, especially when using ERW pipe (refer to Figure 7.7) and higher strength pipe material (...
A variation of PEX pipe is a composite pipe made by laminating an aluminum layer between layers of plastic; such a pipe has the strength of PEX and the pressure capacity of the aluminum layer. In such a multi-layer pipe, the aluminum can act as a diffusion barrier, and, in addition, ...
