ASME B31.1:2026

Annotation of standard text ASME B31.1:2026 :

ASME B31.1 prescribes minimum requirements for the design, materials, fabrication, erection, test, examination, inspection, operation, and maintenance of piping systems typically found in electric power generating stations, industrial and institutional plants, geothermal heating systems, and central and district heating and cooling systems.It also covers boiler-external piping for power boilers and high-temperature, high pressure water boilers in which steam or vapor is generated at a pressure of more than 15 psig [100 kPa (gage)]; and high temperature water is generated at pressures exceeding 160 psig [1,103 kPa (gage)] and/or temperatures exceeding 250 degrees F (120 degrees C).ASME B31.1 is one of ASMEs most requested codes, widely adopted by jurisdictions worldwide. It is prominently referenced in ASMEs Boiler and Pressure Vessel Code, Section I.This Code serves as a companion to ASMEs B31.3 Code on Process Piping as well as to the other codes in ASMEs B31 series. Together, they remain essential references for anyone engaged with piping.Intended for manufacturers, designers, operators and owners of piping systems including, but not limited to, steam, water, oil, gas, and air services, plus all potential governing entities.
