We have experienced weld failure on a number of branch to header connections in thin-wall pipe. The application is 8-inch branches on a 20-inch flare header, where both main run and the laterals are specified as schedule 10S gr. 304 stainless steel.We have had our own problems with welding and quality control in this material but we have a secondary concern as follows. The piping designer has specified "Weldolets" on his MTO, and I am assured that the installed fitting is a proprietary one with an API mark, but I am not convinced that our contractor supplied and installed the correct fitting. What has been installed looks like a simple sleeve placed over the branch pipe and not properly contoured to the main run.
I guess what I'm looking for is a picture of what would regard as a "typical" proprietary reinforcement for the application.
Thanks
