Thank you for the comments. I've got a good idea of what is required now. Many Thanks guys,

Hi guys, A real quick one... If the level of NDT of a weld is defined as 20% does this mean that 1 in 5 of welded joints needs to be tested or that 20% of every joint needs to be tested? For example, If there are 10 butt welds that require 20% MPI, does this imply that 2 out of 10 of the...

Thank you for the reply. Do you have a section of reference for AWS D1.1?

All, Seen there are other threads on this subject but they are now closed. A colleague of mine stands by his rule of thumb that the maximum weld leg length can not be greater than the minimum thickness of the two pieces being welded together. I can see the rule holding for thin gauge metal and...

Yes good point MintJulep. Thanks for the information CoryPad. Some interesting bits of kit there.

MintJulep, the torque will be measure with a torque wrench, the elongation is to be measured with calipers. Redpicker, please read my post as "digital calipers with a PC interface", disregard the vernier aspect. I often refer to vernier gauges as calipers. Thanks,

Hello All, I need to record the continuous elongation of a bolt as torque is applied. I was planning on using an electronic digital vernier and connecting it to the pc similar to the below: http://digital-caliper.co.uk/product_info.php?products_id=395 Does anyone have any experience of this...

RobyengIT - Thanks for the documents, I've reviewed them both and I think the example calculation will be a useful reference in future calculations. XL83NL - Thank you for the direction in regards to stress factors. I will review and post on my progress. Thanks again

Hello All, Does anyone have experience with BS EN 13480 Metallic Industrial Piping? I'm trying to find the equivalent section to ASME B31.3 Appendix D that deals with stress intensification factors for elbows and pipe bends. Also, I can't seem to find any section in BS EN 13480-3 or BS EN...

Two fantastic responses already, thanks guys. I have attached a very quick cad sketch of the joint in question. The gold cross members are those I'm investigating. KootK - Yes groove weld where the two beam flanges meet as the two beams are required to finish flush with each other. The...

Hello All, Has anyone come across slotted H-beam through joints as a means of simplifying skid frames and base frames manufacture for steel structures? https://www.youtube.com/watch?v=5Kv2xAsP8YI I am thinking of a skid base frame with two full length H beams (203x203x52) requiring equally...

Duwe6 perhaps you can help me further - If the joint was partial penetration only, would it still come under UW-13.2(e)?

Thanks for your post Duwe6.

Hi everyone, I need some help locating the relevant weld size for a full-penetration weld on a partition plate (stay) for a non-circular pressure vessel (Air cooled Heat exchanger header box). I assume it should be minimum weld size (Throat) to be < Min plate thickness, however I need a...

Thanks everyone!

Hello Everyone, Does anyone have a .pdf copy of: 'Development of Design Charts for Bolts Preloaded up to the Plastic Range', N. Motosh, Journal of Engineering for Industry, ASME Aug. 76 We have calculation sheets referencing this paper that I would like to verify, Many Thanks, Rich

Not very helpful SnTman, but thanks anyway. MikeG7, I appreciate your feedback. I have calculated the flat side minimal wall thickness using UG-34, this is acceptable. I have calculated the bending stresses and membrane stresses of the flat sides and compared this to the allowable material...

Evening All, I am working on a rectangular stayed header box for an air-cooled heat exchanger and I am using ASME VIII Appendix 13 to complete the stress calcs on the pressure vessels components. During a recent design review, I was asked to provide proof that the stress calcs adhere to section...
