ASME Section I Organization and Structure

Purpose of ASME Section I

The primary objective of ASME Section I is to provide rules for the:

Design of power boilers Material selection Fabrication and welding Examination and inspection Pressure testing Certification and stamping Overpressure protection Installation considerations

The Code establishes mandatory requirements intended to achieve an acceptable level of safety and reliability throughout the boiler's service life.
