Materials & Welding

Dear Experts, For one of our project, we have done welding for various sizes ( 2", 3" , 4" , 6", 10" 14".16" with Min 5.5 T to Max 12.7 T ) of A106 Gr.B to A105N Flanges with Circ. Seams of 68 units, out of that only 10 units were done PWHT as per client requirements,   as per the attached photo and also 2 number of CS 1/2" Nipples with an A105N Adaptor of 36 mm Dia welded on the pipe,  but one of the adaptor weld touches the right end Circ. Seam, referring to the photo . During design, we over looked it and all the design and drawings approved by owner, the design is as per ASME B31.3 2016 ED. the WPSs were approved, so fabrication was done and Hydrotest also done. Now, before delivery, the Owner has sent their welding spec , which they have not sent EVER before and the spec mentions that min 50 mm gap to be maintained. So, we recommended with a TQ for a Simulation Test to prove that the hardness on weld and HAZ not to exceed 248 HV 10 as per th...

Dear all,  Please,  how to proceed or way to welding the reinforcement pad and nozzle for manhole to shell?

If Lab is authorized by national, international (ISO/IEC 17025) or by the Client, you can review the parameters and you can approve.You should have adjustment there is no malpractice have done by both of them. You can also review any past experience with the lab and you can also go and witness the lab calibrations and qualifications, if everything OK then only you can make an NC for why there is communication gap happened? otherwise you can not reject the WPS unless there is any one suitable reason. Just my opinion. Best Regards, Venkat.

Hello, NDE(RT) and Hydrotest both having different purpose. NDE are carried out to ensure the defect free joints and hydrotest is carried out for strength well as leak test. NDE we are only doing at weld and their HAZ area. However before putting in the system complete piping system need to be tested.   Incase of golden/ closure weld where Hydrotest is not possible there 200 NDE shall be carried out but this is not applicable for all the joints.   Regards Aakash   From: materials-welding@googlegroups.com <materials-welding@googlegroups.com> On Behalf Of Eng.Mahmoud kamel Sent: Wednesday, October 23, 2019 11:30 AM To: materials-welding@googlegroups.com Subject: Re: [MW:30176] Hydrotest of Pipings   Never ,    selection for RT 100% not mean no hydro test , only for golden joint which for few case hydro test not possible.   what ever you need you have to cover by Clint specification  and owner approval          ...
