I have enclosed a copy of these\nregulations entitled, \"Part 195 - Transportation of Liquids by Pipeline,\" along with the current\namendments to the regulations.\nPart 195 pertains to pipelines of all sizes. The formula for internal pressure design is contained in\nSection 195.106 and that formula takes into consideration the stresses relative to size. That is, if all\nother variables in the formula, such as wall thickness, yield strength and seam joint factors are constant,\na large diameter pipe cannot operate at as high a pressure as a small diameter pipe.\nPlease contact me if I can be of any further assistance.\nSincerely,\nFrank B. Fulton\nChief, Technical Division\nOffice of Pipeline Safety\nDB/dal/195.106\n71-07-02","truncated":false,"body_characters":1270}
