I have seen manufacturer supply dual certified material as A105/A 350LF2. Similarly can casting be dual certify by mfg as A216Gr WCB/A352 Gr LCB????. has any body came across such certified casting????

Brimstoner, As the hardness reading below 12 mm thickness are not reliable by using EQUIOTIP portable hardness tester. I have proposed customer that we will put additional test piece of pipe in the PWHT cycle each time & will test it in test lab by conventional method.But customer came with...

I have to comply with NACE MR0103

I have to mfg a A 358 TP 316L CL1 welded pipe using SAW process. can anybody suggest a associated Flux & wire for SAW welding. solution anneling will be done on pipe at 1100 deg C.also ferrite Number is to be found out for weld metal. pipe should pass impact at -196 deg C. Size of pipe is 24"x...

I don't have copy of API 1104.does the procedure & welder qualification of API 1104 is similar to that of ASME sec IX. or what extra i will need to do for qualify a PQR as per API 1104 I heard that as per API 1104 procedure qualification is allowed only on pipe samples & welder qualification is...

I have to weld a 10 mm thick A 182 F 316 material with A 350 LF2 material. The compliance is required as per NACE MR 0175 & MR 0103. Is PWHT required for this joint as per above two std?. If customer has not specified any of the practises which are outlined in RP 0472, how the compliance can be...

metengr I have done simulation on same heat pipe & results are good after PWHT.The tensile sample did pass the test. Thanks for your help

MikeMet, How much it costs, where i could get it?

I have checked hardness of equipment after PWHT with portable hardness tester(Equotip). The thickness of CS equipment(A106 Gr B/A105) was 9.53 mm & hardness of PM was 110-115 BHN. I thought that tensile property of equipment may have dropped down to its min requirement so I simulate a test...

I have to weld a CS pipe A 106 GrB to transition fitting (IS grade).the material for transition fitting is unlisted in ASME code. I have to develope a weld procedure for the same. How i can do that? does ASME secIX allow that?

What is the code difference in ASTM A 105 & ASME SA 105???

I have to fabricate a block spool piece using A350 LF2 as body & Flange material.Drawing specifies material & fabrication according to MR0103.Design code is ASME B 31.3& wall thickness is 8.56 mm. To meet the HAZ hardness as per NACE MR0103, either i will have to do PWHT or chemestry control...

one of my project valve datasheet sheet specifies the valve body material as A182 Gr 316L & fastener as A320 GrL43(phosphated) & A194 L7.The min temp in datasheet is -29 deg C. I have referred A320 which states L43 grade is for ferritic material, but here my body material is austenitic. Can I...

And what about A 995 Gr 4A
