This standard specifies the technical requirements for manufacturing the boiler pressure parts with welding method and the requirements for inspection and acceptance.
This standard is applicable to the stationary hot water boilers as well as the stationary steam boilers with rated steam pressure no larger than 13.7MPa and rated steam temperature no larger than 540℃, and the steam boilers with subcritical pressure may also adopt this standard.
The pressure parts in this standard still include the non-pressure parts fixed on the pressure parts by welding method for the purpose of bearing loads.
The welding methods in this standard include gas welding, manual arc welding, submerged arc welding, gas-shielded arc welding and electroslag welding. Where other methods are used, the manufactory shall formulate the corresponding technical requirements and inspection and acceptance requirements by making reference to this standard to make the welding quality be not less than those specified in this standard.
