תקניםASME 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.
תקניםASME B16.39 covers threaded malleable iron unions in Classes 150, 250, and 300, including design, ratings, materials, threads, and tests. This guide explains what EPC engineers and procurement managers must verify when specifying these unions.
תקניםASME B16.3 covers malleable iron threaded fittings in Classes 150 and 300, including ratings, dimensions, threading, and coatings. This guide explains the standard's scope, key requirements, and procurement checks for EPC engineers and buyers.
תקניםASME B16.14 covers ferrous pipe plugs, bushings, and locknuts with pipe threads, including ratings, dimensions, materials, and marking. This guide explains the standard's scope, key differences from ASME B1.20.1, and what buyers must verify to avoid specification errors.
תקניםASME 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.
תקניםASME 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.
תקניםASME 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.
תקניםASME 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.
תקניםASME 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.
