Archived Rulemaking:Transportation of Hazardous Liquids by Pipeline; Qualification of Welders

49-fr-19875.pdf (237.81 KB)

MTB proposes to incorporate by reference Section IX of the American Society of Mechanical Engineers Boiler and Pressure Vessel Code (ASME Code), 1977 Edition, for welder qualification into Part 195 in addition to the presently required API Standard 1104 (API 11104). Allowing the use of the ASME Code to qualify welders will bring the requirements for hazardous liquid-pipelines into line with 49 CFR Part 192, the Federal safety standards for gas pipelines.
