구매 가이드A practical RFQ checklist for ASME B16.49 induction bends, covering geometry, material, testing, and documentation requirements for transportation and distribution piping.
표준ASTM A694/A694M covers forged or rolled steel flanges, fittings, valves, and parts for high-strength transmission-service pipe. This guide explains grades, procurement checks, and inspection points for EPC buyers.
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.
구매 가이드Specifying orifice flanges requires more than a standard flange RFQ. This checklist covers ASME B16.36 scope, class/type limits, tap details, and documentation gaps to verify before ordering.
표준ASTM A182 covers forged low-alloy and stainless steel flanges, fittings, valves, and parts for high-temperature service. This guide explains what buyers must specify beyond the standard, including grade, heat treatment, and dimensional standards.
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.
구매 가이드Gray iron and ductile iron flanges are covered by different ASME standards with distinct classes and ratings. This guide explains the key differences, procurement checks, and RFQ requirements to avoid costly specification errors.
표준ASME B16.42 covers cast ductile iron flanges and flanged fittings in Classes 150 and 300. This guide explains scope, key requirements, and procurement checks for EPC engineers and buyers.
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.
