Hello.

We are designing one vessel in accordance with ASME Sec VIII Div 1, Ed 2007 & PED 97/23/EC.

I wish to get a procedure qualified for this vessel. Since the vessel is operating at a very high temperature, I need to prove that the material can withstand the hot temperature tensile test. Welding is as per ASME Sec IX.

What is the minimum size of coupon plate required as per EN 10002:5 "Tensile testing of metallic materials". For example, I have a coupon plate of 50 mm long, 200 mm wide x 6 thk. Can I weld it to another coupon plate of same size and carry out the test?

I would really appreciate your opinions.

if your vessel is designed to ASME Sec VIII you must test it as per SA370, even thhou its an EN material

Dear Mr. Raghuram,

Thank you very much for your reply.

The materials are in accordance to ASME Sec II Part A and D.

Secondly, I checked with SA 370. Does it specify "creep" test?
