StandardsASME B16.1 covers gray iron flanges and flanged fittings in Classes 25, 125, and 250. This guide explains what the standard includes, how it differs from ductile iron (B16.42), and what buyers must verify when sourcing gray iron flanges.
StandardsASME B16.49 covers factory-made induction bends for transportation and distribution piping (B31.4, B31.8, B31.11). It is not for process or power piping. This guide explains scope, key requirements, and procurement checks.
StandardsASME B16.36 covers orifice flanges for differential pressure flow measurement. Welding-neck types span Classes 300–2500, while slip-on and threaded are limited to Class 300. This guide explains scope, procurement checks, and common pitfalls.
StandardsASME B16.21 defines dimensions, materials, and markings for nonmetallic flat gaskets used with ASME flanges. Learn what it covers, what it doesn't, and how to specify gaskets correctly.
StandardsASME B16.20 defines dimensions, materials, and tolerances for metal ring-joint, spiral-wound, and metal-jacketed gaskets. This guide explains the standard's scope, flange compatibility, and procurement checks for EPC buyers.
StandardsASME B16.11 defines Class 2000, 3000, 6000 for threaded fittings and Class 3000, 6000, 9000 for socket-weld fittings. This guide explains what these classes mean, how to specify them, and what to verify when procuring forged fittings.
StandardsASME B16.48 covers line blanks from NPS 1/2 to NPS 24 for ASME B16.5 flanges in pressure classes 150–2500. Learn what the standard includes, what it doesn't, and how to specify and inspect these components.
StandardsUnderstand the key standards for butt-weld pipe fittings, including material grades, dimensional requirements, and inspection documents to request from suppliers. This guide helps engineers ensure quality and compliance in pipeline projects.
StandardsASME Section II Part D allowable stress lookup explained for procurement engineers: tables 1A, 1B, 3, derivation rules, and how to use them on a data sheet.
