Hi,

 

You can refer BS 6990 (Welding on steel pipes containing process fluids or their residuals)

 

1 Scope

This code covers operations relating to and involving arc welding on ferritic steel and austenitic stainless steel land or offshore pipelines and process plant pipework which contain or have contained a process fluid and which are at least 5 mm thick. It gives details of procedures prior to, during and after all these operations.

Thanks,

 

Rajasekhar
