StandardsAPI 6D pipeline valves explained for international procurement: scope, valve types, pressure classes, piggability and order specification checklist.
StandardsAPI 6A wellhead flanges vs ANSI ASME B16.5 flanges: pressure ratings, RTJ requirement, material classes, PSL levels and where they overlap for buyers.
StandardsWhat every EPC buyer should know about ASME B16.34: pressure classes, material groups, derating with temperature and procurement specification points.
StandardsProcurement guide comparing ASME B16.5, B16.47 Series A (ex-MSS SP-44) and Series B (ex-API 605) large diameter flanges with size and pressure ranges.
StandardsWet H₂S environments demand specific material chemistry, hardness limits, and heat treatment. Here is what NACE MR0175 actually requires for buttweld fittings and forged flanges.
StandardsEN 10253 and ASME B16.9 cover the same product family but diverge on a few sizes, on PED conformity, and on allowable stresses. Buyers shipping into the EU need to read the small print.
StandardsASME B16.9 covers everyday carbon and alloy steel fittings. MSS SP-75 is for high-yield, high-pressure pipeline service. Here is when each one applies — and why mixing them is a costly mistake.
