기술Macroetch 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.
기술Learn how ASTM E1077 and A960/A960M apply to decarburization depth on heat-treated fittings, and what to specify in your RFQ to avoid disputes.
기술Grain 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.
기술Charpy impact records for pipe fittings often include subsize specimens. Learn what ASTM E23 and A370 actually require, and where acceptance criteria must be found.
기술Weld repair acceptance for A234 and other wrought steel fittings is governed by the product specification, A960/A960M common requirements, and the purchase order — not by a generic visual pass/fail rule. Here's what to verify.
기술ASTM A960 sets common requirements for wrought steel pipe fittings covered by individual ASTM product specs like A234. This guide explains what buyers must verify when ordering and inspecting fittings.
기술How to verify heat identity, heat analysis vs product analysis, mechanical test evidence, and RFQ requirements when buying forged flanges to ASTM A961 and A105.
기술ASME publishes separate standards for metallic and nonmetallic gaskets. This checklist helps buyers cross-check gasket type, flange facing, and procurement details before issuing an RFQ.
기술ASME B16.21 defines nonmetallic flat gaskets for pipe flanges. This guide explains the standard's scope, why you must pair it with the mating flange standard, and what to verify during procurement to avoid misapplication.
