Hi,
We are welding a structure with AWS 1.1, where there are 40mm pad eyes which are CJP with double V-joint. Thickness of other parts are between 6 to 20 mm. As per contract with client PWHT has to be done on whole structure. As per AWS 1.1 for 40mm thickness the holding time is 100 minutes...
Where can I get the material properties of AISI4130. We are using it for API flanges at 10K pressure for CE marked package. AISI4130 is unlisted material in ASME B31.3
API code doesn't help much on properties.
We are using 26" pipe as shell for H2S stripper vessel. The design requires A106B normalised Pipe. We can only get pipe formed in Normalised condition. Can we use the pipe.
