ASME VIII vs TGL Pressure Vessel Strengths
ASME VIII vs TGL Pressure Vessel Strengths
(OP)
I am currently reviewing the design of a pressure vessel designed in Germany in 1987 to TGL in order to comfirm it's adequacy against the requirements of ASME VIII. I am finding that the wall thickness required under ASME VIII for the nominated design pressure is greater than that used in the construction of the vessel.
Does anyone know how the maximum allowable tensile strength for carbon steel materials (A283 GrC) was determined in the applicable TLG (in 1987)?

Craig

Can you tell me what the european (particularly German) ultimate strength factor would have been when this vessel was designed (87)? I know ASME back then was UTS/4 (now UTS/3.5).

I have a copy of AD-Merkbl. dating back to 1988 (!): don't know very well this standard, but I understand that the allowable stress is obtained by simply dividing by 1.5 the following example values:
St-37 thk.up to 16 mm temp.between 50 and 100°C: 187 Mpa
St-44 as above: 220 MPa
St-52 as above: 254 MPa

Looks like I will have to dig a bit deeper and see if I can locate the original calculations to get to the bottom of this.
Thank you for your assistance.
