Is not ASTM E1820 for metallic materials? I thing ASTM D 5045 or D5528 or D6671 or D7905 may be the correct standard.

Valves are not 6A We have B16.34, API 6D, ISO 17292 valves in our project.

With respect to ISO 15848-1 is temperature class = Design temperature? Should the target temperature be the design temperature of the valve? If so where is it specified or where will it be specified? Is there any ISO standard or BS EN standard or code (not the client specification) that...

When the standard b 16.9 fitting has long seams, for using such a standard Fitting in Pressure vessel,is it required for the pressure vessel manufacturer to obtain the WPS and PQR and get it reviewed by AI and include in the final dossier, also is PQR for the fitting required to take into...

If the material is as per ASME Sec II A, take a copy of the ASME Sec II A and check for the certification requirements and verify whether all the basic certification requirements are met. For example, if the material under consideration is SA 106, then the requirement for this is given in ASTM...

Alternatively you may use UW 42 of ASME Sec VIII Div 1 UW-42 SURFACE WELD METAL BUILDUP (a) Construction in which deposits of weld metal are applied to the surface of base metal for the purpose of restoring the thickness of the base metal for strength consideration; shall be performed in...

If a specification states that the valve shall be made from A 182 Tp 316 L forging and if a manufacturer machines the valve components from A 479 SS 316L forged Bar is it OK, the valve is 3" flange rating 600 rating and is dimensioned to B 16.34, API 6D, . Where as the clause 5.4 The material...

If your contract invokes ISO 15156/NACE MR 0175 then ferrite content in Duplex weldment becomes mandatory

Yes metengr, you are right about the note b, it talks about Forged Bar. What about S5.2.3 My submission is this, a standard either in supplementary or in mandatory portion discusses about rod and bar, then there is a scope for inferring that bar or rod be used.

I beg to differ with such assertion, kindly see the foot note "b" of table 2 and also the S5.2.3, where in there are indications that bars may be made to B 564. If bar were not to be part of B 564, why then the table 2 which dwells into the mechanical property, provide the value for tensile...

Not all alloys in A 182 requires grain property
