Thank you for your responses bcd and LittleInch! I've not referenced MSS SP-67 before, but I'll get hold of a copy and have a read. I also take your point regarding the shock loading. I will crunch a few numbers, I'm curious to see how close the wall thickness calcs compare between BS EN...

We have an enquiry for a very large axial nozzle check valve (>60in) to be manufactured from carbon steel. The customer has specified a relatively low design pressure (~8barg) which is well below the material specific ceiling pressure for a 150# valve (ASME B16.34). The customer has specified...

Hi folks, I am currently calculating the required thickness for a a custom blind flange (test plate) for our internal hydro shell test (1.5xDP). I normally refer to 12516-2 section 8.2 to determine the thickness (hc) either when the plate is with or without concentric opening (8.2.2 & 8.2.3...

I have noticed the standard thickness for this size and class in B16.5, and it would always be my first choise to use a steel plate. However, as I mention, we already have the ductile iron plates from a previous job a from a long long time ago. To buy new plates (when it's not absolutely...

Hello, We have a requirement to test a number of large nozzle check valves (60"-300# Series B) shell and seat test (1.5xDP & 1.1xDP respectively). We need a pair of blind flanges to seal the unit for testing, we have a pair of plates (9in thick) made of Ductile Iron A395 60-40-18. I have done...

I've used this forum a number of times, but I've taken the plunge and joined as I have a question I'm struggling to answer... I've done a number of searches on this forum about the use of C95800 as a valve body material... As this material is not listed in either ASME B16.34, ASME II Part D or...
