ΤεχνικάASTM G82 and G71 provide structured guidance for predicting and evaluating galvanic corrosion. Learn how to apply them when procuring pipe fittings and flanges for mixed-metal systems.
ΤεχνικάUnderstand ASTM G36 and G30 for stress-corrosion cracking screening of fitting alloys. Learn what to specify, inspect, and avoid in procurement.
ΤεχνικάASTM G48 ferric chloride tests and ASTM A923 phase detection are complementary, not interchangeable. Learn what to specify, inspect, and verify when buying duplex fittings.
ΤεχνικάASTM A262 and ASTM A763 detect intergranular attack in austenitic and ferritic stainless steels respectively. Learn which practice to specify, how to write RFQs, and what to check on test reports.
ΤεχνικάSelecting between ASTM A1084 and A923 for lean duplex fittings requires matching the standard to the alloy. Learn what to specify in your RFQ, how to verify test reports, and how to avoid common acceptance mistakes.
ΤεχνικάDuplex fittings require two distinct metallurgical checks: ferrite volume fraction by ASTM E562 and detrimental intermetallic phase detection by ASTM A923. Procurement buyers need to understand the difference before specifying.
ΤεχνικάMacroetch per ASTM E340 helps reveal weld penetration, cracks, and HAZ features. Learn how it fits into ASME Section IX qualification, what to verify, and RFQ inputs for buyers.
ΤεχνικάLearn how ASTM E1077 and A960/A960M apply to decarburization depth on heat-treated fittings, and what to specify in your RFQ to avoid disputes.
ΤεχνικάGrain size testing under ASTM A182 is mandatory only for certain grades. Learn when ASTM E112 applies, which methods are used, and what buyers must verify before accepting a fitting.
