Greetings All, I am very new in Ansys and I need to use it for my School project work. I am working on the prediction of inner wall temperature of pipe during in-service welding using Mechanical APDL 2D Steady State thermal analysis. My problem is this, my welding heat energy input is in...

Thanks pradipgoswami for the document.

ironic metallurgist (Materials) Just like you suggested, we were able to get advice for the welding consumables. EdStainless (Materials) For this procedure, impact toughness test is not required. Thanks All

Good-day All, Thanks to all for all your inputs. The material in question is SEAMLESS STAINLESS STEEL LINE PIPE 13%CR-2.5%MO. We will have to put up a pWPS, and carry out the procedure qualification process to see what happens. Thanks to all Chitessy

Goodday Everyone, Please, any one that have been involved in the welding of a gas line of pipe material: 13Cr weldable martensitic steel. I will sincerely appreciate your advice and if possible any draft pWPS that could be of help and guide. I have had suggestive inputs from senior colleagues...

SectionIX (Petroleum), Many thanks for the clarification.

Dear All API 1104, Section 5.4.2.2 I have a PQR qualified with API 1104 FOR 18'' X 12.7MM X60 API 5L PIPE. P-No. 1 and G-No. 2 and welding process is SMAW Can I formulate a WPS from this PQR for 24'' X 15.8MM X65 SCH80, API 5L PIPE. P-No 1 and G-No. 2 and the welding process is SMAW...

Thanks All for your responds, I sincerely appreciate. Chitessy

All, Please I will like to know if there is any code or specs on how many times you can cut out a flange and re-weld that same flange. We have a 24'' X 900#. In modifying a pipe spool, we cut out the flange and we want to re-use it. is there a limit to the number of times we can re-weld a cut...

Thanks All, I have qualified a welding procedure with ISO 13847 and another procedure with ASME B31.3 together with ASME SECTION IX. I qualified the procedure, supervise all the test coupon welding, NDT and mechanical test, PQR and finally produce the final WPS which are being use for the...

Is a Gas line and the material is API 5L Grade B 18" X 12.7MM

Hi All, Am writing a propose welding procedure specification for a 18" X 12.7 MM pipeline of about 1 kilometer in length using API 1104. I will need advice if post-weld heat treatment is necessary. Thanks All Chitessy

DekDee, Thanks so much. I was able to get ASME IX and everything I needed is just right there just as you said. I sincerely appreciate your help. Once again, thanks so much. Regards Chitessy

Hi All, I am qualifying a welding procedure for both 10" and 24" pipe using ASME 31.3. This is the code the company recommend. Please can any one assist me on the position to cut the weldment for the Tensile, Impact, Hardness, macro, side bend and all weld metal test from according to B31.3...

Thanks All, All responds is appreciated. All suggestions tends towards the same thing that I know. I wanted to know other people's view to be sure am not missing things up because at times different company uses different abbreviation. Once again, Thanks Chitessy
