Thanks for the response and apologies for not replying sooner. I don't think so as EN 13445 paragraphs 8.4.2 and 8.4.3 refer to Rp0.2T for both CS and SS. SS seems to be taking a hit and I don't understand why.

Hi, I'm a little confused by the requirements of EN 13445 paragraphs 8.4.2 and 8.4.3. For shells made in non austenitic steel the nominal elastic limit is given by Rp0.2/T but for austenitic steel it's the same value divided by 1.25. Could anyone help with an explanation as to why the nominal...

Hi, BS1501-224-490B-LT50 has already been impact tested at -50degC, hence the LT50 in the designation. Firstly you need to calculate the design reference temperature, this is not the same as the design temperature but it might end up as the same value. Use this in Annex D figure D.1 to...

Probably a little late to respond but I'd recommend PD 5500. PD 5500 contains specific guidance on Titanium vessels. I'd also be interested why your client insisted on using a European vessel code, there is no reason why ASME vessels cannot be used in Europe provided extra steps are taken to...

Sorry I don't know any North American manufacturers that make CE marked vessels. ASME do publish a book giving advice on the extra requirements: Guide for ASME Stamp Holders for Section VIII Division 1 Vessels and the Pressure Equipment Directive BOI - 2001 ISBN 0791827127 It may be worth...

European regulations require all ferritic materials to be impact tested at or below the minimum operating temperature, but not greater than 20C, with an energy no less than 27J. Sorry but you can't use the charts to get out of the impact test you just have to do it.
