ASTM A234 standard steel pipe fittings have been widely applied in pipeline systems, it includes carbon and alloy steel material. Steel pipe fitting are made of carbon or alloy steel pipe, plates, profiles, to a certain shape that could make a function (Change the fluids direction or rate) in pipeline systems. Mostly these fittings includes steel elbow (45 or 90 degree bend), tee, reducer (concentric or eccentric reducer), cross, caps, nipple, flanges, gasket, studs and etc. For industrial purposes, in pipeline systems usually we need to change the transmission direction; Adjust fluids (oil and gas, water, slurry) flow rate; Open or close the pipelines, etc. So to complete these activities, steel pipe fittings will be applied. Below we will introduce you alloy steel pipe fittings.

The alloy steel pipe fitting is fabricated with alloy elements in such as Chrome, Molybdenum, Nickel alloy, Hastelloy alloy, Monel, Inconel, and etc. To get a higher pressure ratings, better strength, good corrosive resistance, and longer durability. It is widely used in oil and gas pipelines, chemical industries, power plants, nuclear power sites, and in server conditions.

Alloy steel pipe fittings includes buttweld fittings, alloy steel long radius bend, alloy steel forged fittings and so on.

The alloy steel buttweld fittings adopts ASTM A234 standard, has WP1, WP5, WP11, WP12, WP22,WP23 and WP91 grades. Class level in CL1, CL2, CL3.

ASTM A234 alloy steel pipe fittings inlcludes alloy steel elbows in long and short radius, alloy steel eccentric & concentric reducer, alloy steel caps & crosses, alloy steel couplings, alloy steel tees, alloy steel nipples, alloy steel caps and etc more forms. It has seamless, welded and fabricated types.

For alloy steel forged fittings, it adopts ASTM A182 standard refers to steel pipe flanges. Material standard in ASTM A182 F1, F5, F9, F11 Class 1, F12 Class 1, F22 Class 1 ETC.
