Experts,     We have received   Female Sprinkler Head Adaptor 3/4"* 1/2" size .This adaptor shall be made socket weld with 1" Pipe. But ID for the 1" pipe is 25 mm and id for Female Sprinkler Head Adaptor 3/4"* 1/2" is 27.5 mm (Pls see the attached pics ).   If we weld Pipe to adaptor , we will not be able to get Weld penetration with this size deviation. Can we do Butt Weld in this case?   Kindly advice.   Best Regards,   Krishana Kamal Nayan QA/QC  Engineer Weatherford Oil Tool Middle East Ltd.  | Mobile: +964 780 925 0270 Krishana.Nayan@ME.Weatherford.com   │  www.weatherford.com   -- You received this message because you are subscribed to the Google Groups "Materials & Welding" group.

If your fabrication is governed by ASME Boiler and Pressure Vessel Code the answer is unequivocally NO.  You need to perform a qualification with P5B and P8 materials.    From: materials-welding@googlegroups.com [mailto:materials-welding@googlegroups.com] On Behalf Of JIJILAL K M Sent: Wednesday, January 27, 2016 2:38 AM To: materials-welding@googlegroups.com Subject: [MW:24176] can use P15E wps for P5B   Dear Experts,   We've to weld 4" x 6.02 mm  HRSG boiler piping joints (only 2 nos.).   Materials are   P5B + P8   ( ASTM A335 P5 + ASTM 304L SS) .   There is no such qualified  WPS.   instead we've a Qualified WPS  for P15E + P8   ( ASTM A335 P91+ ASTM 358  316L SS) .     Can we use this WPS using filler wire ER-309?   JIJILAL  K.M.    ...

Dear Jijilal,                  It is a strange fact that you have already qualified P15E+P8 with ER-309!! You have to use Inconel filler wire or Nickel based filler on this dissimilar metals, as per your requirement. And you have to check how you qualified the WPS, by buttering or by normal butt welding and PWHT. I am saying this because normally, we won't do PWHT to P8 materials because of high PWHT temperature, which may affect the paramagnetic properties of stainless steel.

Hi Adrian,   Preheating will not needed to repair these welds. However some local preheating would be advisable to drive away the moisture and make the weld joints dry, so as to produce good quality welds. Presence of moisture could cause porosities in the welds.   It would be advisable to cut a boat sample form one or two the T-TS welds and send the same to the labs for failure analysis to find out the root cause of failures. These points may subsequently be plugged. If your client wants to retain the exchanger in operation for more sustained period of time then the root cause determination would definitely help .   Appreciate your thoughts and future course of actions.   Thanks.   Pradip Goswami, P.Eng,IWE Independent Welding & Metallurgical Engineering Specialist & Consultant.
