This chapter discusses the building services piping for heating, cooling, and compressed air installed in industrial, institutional, commercial, and public buildings and multiunit residences. Generally building-services piping operates at relatively low temperatures and pressures. ASME Pressure Piping Code, Sec. B31.9, Building Services Piping, was developed to employ a simplified approach. ASME B31.9 covers the piping which does not require the ranges of sizes, pressures, and temperatures covered in ASME Pressure Piping Code, Sec. B31.1, Power Piping.
Every plot of land is under the authority of a jurisdiction. It is necessary to obtain a building permit from the authorities having jurisdiction over the property on which the building is to be placed. To obtain a permit the plans must show that the building is to be built in conformance with the building code which has been adopted by the local authority. The local authority has its own construction codes or has adopted one of the several national codes.
Building codes are omnibus-type documents which treat all aspects of construction and specify safety requirements as well as referencing safety codes written by other code-writing organizations. Building codes, safety codes, and standards are updated periodically by the issuing organizations, and the latest revision should be used.
A listing of code-writing bodies and the specific sections of the codes which control piping follows:
