TeknisASTM A388/A388M and ASTM E114 are key standards for ultrasonic examination of steel forgings. Learn what they cover, why acceptance criteria must be stated in the order, and what procurement engineers must verify.
TeknisASTM E797 covers ultrasonic thickness measurement but has limited applicability on curved fittings. Learn key variables, procurement checks, and inspection requirements for elbows, tees, and reducers.
TeknisASTM 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.
TeknisUnderstand ASTM G36 and G30 for stress-corrosion cracking screening of fitting alloys. Learn what to specify, inspect, and avoid in procurement.
TeknisASTM G48 ferric chloride tests and ASTM A923 phase detection are complementary, not interchangeable. Learn what to specify, inspect, and verify when buying duplex fittings.
TeknisASTM 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.
TeknisSelecting 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.
TeknisDuplex 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.
TeknisMacroetch 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.
