The American Society for Mechanical Engineers (ASME) maintains a Boiler and Pressure Vessel (B&PV) Code which contains material standards and specifications that cover tanks made from carbon and alloy steels. The ASME codes govern design, construction, maintenance, and inspection of power boilers, heating boilers, nuclear power plant components, pressure piping systems, and pressure vessels operating at 103 kPa (15 psi) and higher.
The American Petroleum Institute (API) has prepared material specifications for welding steel tanks, vessels, and tubular products used in the petroleum industry.
Persons involved in tank welding should become familiar with the ASME B&PV Code and API Standard 1104. Refer to American Welding Society, Welding Handbook, Volume 1, 8th Edition, American Welding Society, Miami, Florida. 1989.
Tank Repair- There are many types of tanks and piping systems which have contained hazardous substances. All are potentially dangerous. Information on safe practices for tank repair is found in ANSVAWS F4.1, Recommended Safe Practices for Preparation for Welding and Cutting of Containers and Piping.
Metal storage tanks commonly located at the top of buildings to supply water for private fire protection are welded subject to rules and regulations of the American Water Works Association (AWWA) and the National Board of Fire Underwriters. These rules are set forth in ANSVAWWA DlOO (AWS D5.2), AWWA Standard for Welded Steel Tanks for Water Storage.
