ASME B31.4 vs B31.8
- Thread starter suraiya
- Start date
Volume transfered per unit time as a function of compressability. Liquid is not compressable, gas is, pump setups and compressor stations along the pipeline.
Also there are special considerations for gas transfer measurement governed by AGA Report Number 3. The code does apply to liquids, gases independently BUT NOT two phase flow.

B31.8 has requirements for the more dangerous gas service that are not contained in B31.4. For example B31.4 uses 0.72 everywhere. B31.8 will alter the design factor based on class location. B31.8 has more stingent toughness requirements that are not in B31.4.
