Alloy Steel and carbon pipe Fittings

ASM A234 standard steel pipe fittings have been widely applied in pipeline systems; it includes carbon and alloy material.

What are Metal pipe accessories?

Steel water line fitting are constructed with carbon or alloy steel pipe, china, profiles, to some condition that could make an event in pipeline systems. Mostly these fittings includes studs, gasket, flanges, nipple, caps, cross, reducer, tee, steel elbow and so forth.

For professional purposes, in pipeline systems usually we need to change the transmission direction; Adjust essential fluids flow rate; Open or close the pipelines, and so forth. So to complete these activities, steel pipe furnishing will be applied.


ASTM A234 is Standard Specification for metal pipe fittings includes alloy steel and carbon materials for moderate and high temperature services. It masks steel fittings of unlined and welded types. Metal Pipe fittings are applied in pressure pipelines and in pressure vessel avengement. These fittings material are made up of HFW or seamless pipe products, plates, bars, forgings, steel with filler metal added. ASTM A234 includes wrought carbon dioxide steel and alloy metallic fittings of seamless and welded construction covered by the latest revising

Seeing that we know, ASTM A234 steel pipe fittings are being used in pressure piping and in pressure vessel manufacture, for services at average and elevated temperatures. The fittings material in this standard contain killed metallic, forgings, bars, plates, unlined or fusion-welded tubular products with filler metal added. In this standard it covers the specification of cross, reducers, tees and elbows, it usually adopt butt welding ends.

ASTM A234 includes unlined and welded pipe fixtures

For the seamless stainless steel pipe fittings identifies the fittings raw material from the seamless steel tubes and piping; Thus the welded steel pipe accessories covers the fittings tender material from welded metal pipes. It will probably be known that, an ASTM A234 standard does not cover ensemble welding fixtures or fittings machined from castings.

Steel alloy pipe fittings manufacturing developing processes

The manufacturing functions for pipe fittings include shaping and forging functions. As well as machining, fusion welded, bending, rolling, distressing, extruding, piercing, hammering and hitting or the processes of combo of two or more of these operations.

Alloy metallic pipe fixtures

The combination steel pipe fitting is fabricated with alloy elements in such as Chromium, Molybdenum, Nickel alloy, Hastelloy alloy, Monel, Inconel, and etc. To get a higher pressure ratings, better strength, good corrosive level of resistance, and longer durability. That is widespread in oil and gas pipelines, compound industries, power plants, elemental power sites, and in server conditions.

Alloy metal pipe fittings include butt-weld fittings, alloy steel long radius bend, alloy metallic forged fittings and so on. ASTM A234 combination steel pipe fittings includes alloy steel elbows in long and short radius, alloy steel eccentric & concentric reducer, alloy metal caps & crosses, metal steel couplings, alloy metal tees, alloy steel hard nips, alloy steel caps and the like more sorts. It has seamless, welded and fabricated types.

Intended for alloy steel forged fixtures, it adopts ASTM A182 standard refers to metal pipe flanges.
