Good Morning All, I have a question concerning small bore threaded valves that seem to keep coming up over and over again and I am having a hard time finding anything specific either in B31.3 or PCC-2. If I have a piping circuit that was already tested and placed into service for a period of...

Thanks for the insight Ron

Gentleman , I am going to start y saying I am NOT a AWS code guy ( ASME / API ). I have a client that is building some A36 structural pipe supports with engineered documentation that calls out all welding Shall be IAW D1.1. They have selected a fabricator who qualification base is all D1.5...

Thanks for the response guys , these procedures actually do list a specific material. Right in the scope section of the WPS it defines the WPS to be used for welding X70 material.

I have a client that has sub-contracted a small fabrication shop to build some piping spools IAW B31.3 , the fabrication shop currently has only handled API 1104 fabrication and does not have any welding procedures and the client has agreed to supply them with the procedures to use. We are...

Thanks bud

Weldstan - When referring to the latest code that is giving exception to the P1 over 3/4" rule. I only have access to a copy of 2013 are you refereeing to a addendum or the 2015 edition ? I have some 1.218 A333 24" welds that we would like to exempt if possible. I have reviewed my 2013 copy...

Thanks gentlemen for the insight , we made revisions to the WPS to include the single bevel groove design. Once again thanks for the advice.

So then , being that the groove design is not a essential variable for the WPS , and in turn it is not a essential variable for the Welder Qualification does the WPS even need to be revised to show a single bevel joint design ?

Thanks allot

No input ?

I have a customer that wants to know if he can stub in a 6" branch pipe to a 16" run pipe both sch.40 P1 material utilizing his existing groove weld procedure or does a branch connection need a completely new procedure and welder qualification. My first answer was yes that is permissible since...

Thank guys for the insight into this , I am checking with there design group and see what the intended design was originally. Unlike a vessel , nothing is stamped when it shows up on location. Once again thanks.

I have a client that called me last evening with questions about B31.8 and the use of Fillet welds to 36"X1" X52 material. They are wanting to weld a saddle type support in three places along the bottom of the pipe ( Ad Hoc Vessel ) using a circumferential weld down the sides and a longitudinal...
