Pipeline welding excess height
Thread Content
Dear teachers: I’ve been searching for a long time but couldn’t find in which standard or clause the requirements regarding the excess height of pipe welds are specified. Please give me some advice.
Hello, the requirements regarding the excess height left after pipeline welding can generally be found in the relevant provisions of the \"GB 50236-2018 Code for Construction and Acceptance of Welding Works in Petrochemical Enterprises\". The specific clause numbers may vary with version updates; it is recommended to consult the latest version of the specifications for confirmation. .
GB 50683-2011 Code for Acceptance of Construction Quality of Welding Works for Field Equipment and Industrial Piping
These are the requirements regarding the excess height of welds on pressure vessels; they are not applicable to pipes
Mm-hmm, yes. May I ask if the GB 50683-2011 standard can be used?
The construction and acceptance of pipelines must comply with the requirements specified in the design documents; it is not permissible to choose standards on one’s own. Different standards impose varying requirements for the visual inspection of welds as well as for non-destructive testing. It is necessary to refer to the standards given in the design documents and then determine the corresponding requirements regarding the appearance of welds. Section 9.2 of GB50517 also outlines the requirements for the appearance of pipeline welds
