AISI 4340 Forged Fittings, SAE 4340 Threaded Fittings, SAE 4340

Metalfed Engineering is a leading supplier, exporter, and manufacturers of Forged Fittings. The term “forged fittings” refers to two families of pipe fittings (socket weld and threaded) used for small bore pipes and piping systems (generally below 4 inches in diameter for Class 3000, and below 2 inches for fittings in class 6000 and 9000). These fittings are manufactured by forging and machining solid steel and are available in a multitude of shapes like elbows, tees, reducers, unions, couplings. The ASME B16.11 specification covers socket and threaded fittings for oil and gas application. ASME B16.11 standard contains pressure-temperature ratings, dimensions, tolerances, markings and material requirements for forged and threaded forged fittings. SW Fittings are family of high pressure fittings are used in various industrial processes. They are used only in conjunction with ASME Pipe and are available in the same size range. They are used in areas where pipe-work is permanent and are designed to provide good flow characteristics.

Table of Content

Forged fittings are used for piping systems below 2 or 4 inches in diameter (4″ for 2000#/3000# fittings, 2″ for 6000#/9000# fittings). The two main types of forged fittings are the so-called socket weld fittings (which are connected to pipes by fillet welds) and threaded fittings (the pipe is screwed onto the fitting). Forged fittings are manufactured from solid blocks of steel, that are machined to obtain the final required shape within the tolerances set by the applicable specifications mentioned above. This is different from buttweld fittings, which are manufactured by cutting, bending and shaping seamless or welded steel pipes.
