It covers the butt-welded pipe fittings of Elbow, Tee, Reducer, Cap and Cross, and some socket welding, threaded pipe fittings. The specification covers wrought carbon steel and alloy steel fittings of seamless and welded construction covered by the latest revision of ASME B These pipe fittings used in pressure pipelines and pressure vessel fabrication for servic at moderate and increased temperatures. The raw material for making ASTM A fittings hall be fully killed, consisting of forgings, bars, plates, sheet, and seamless or fusion-welded pipe products with filler metal added and shall conform to the chemical requirements of Table 1. Unless specified for carbon steel plates or sheet, the steel may be made to either coarse grain or fine grain practice.

ASTM A 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.

ASTM A is Standard Specification for steel pipe fittings includes carbon and alloy steel material for moderate and high temperature services.

It covers steel fittings of seamless and welded types. Steel Pipe fittings are applied in pressure pipelines and in pressure vessel fabrications. These fittings material consist of killed steel, forgings, bars, plates, seamless or HFW fusion welded pipe products, with filler metal added. As we know, ASTM A steel pipe fittings are used in pressure piping and in pressure vessel fabrication, for services at moderate and elevated temperatures.

The fittings material in this standard consist of killed steel, forgings, bars, plates, seamless or fusion-welded tubular products with filler metal added.

In this standard it covers the specification of elbows, tees, reducers, caps and cross, it usually adopt butt welding ends. In these standard Grade WPB is the most common material used for medium and high temperature pipelines.

W means weldable, P means pressure, B is grade b, refer to the minimum yield strength. B and C. For each reduce of 0. For other grades:. For the seamless steel pipe fittings refers to the fittings raw material from the seamless steel pipes and tubes; Thus the welded steel pipe fittings covers the fittings raw material from welded steel pipes.

The manufacturing processes for pipe fittings includes forging and shaping operations. As well as pressing, hammering, piercing, extruding, upsetting, rolling, bending, fusion welding and machining.

Or the processes of combination of two or more of these operations. And no defects shall be made during the cooling procedures. The cooling rapid shall be not more than in the air. Hydrostatic test, hardness test, tensile test etc. Steel pipe fittings manufacturing types in forged, threaded, butt weld, and seamless.

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. It has seamless, welded and fabricated types. Octal is located in China recognized as a leading supplier, distributor, and manufacturer union in providing piping solutions for oil and gas company.

What is Steel pipe fittings 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.

Forging fittings Carbon content 0. Copper, Nickel, Niobium and Molybdenum sum content shall not exceed 1. For other grades in ASTM A ASTM A includes seamless and welded pipe fittings For the seamless steel pipe fittings refers to the fittings raw material from the seamless steel pipes and tubes; Thus the welded steel pipe fittings covers the fittings raw material from welded steel pipes.

It shall be noted that, ASTM A specification does not cover cast welding fittings or fittings machined from castings. Steel pipe fittings manufacturing forming processes The manufacturing processes for pipe fittings includes forging and shaping operations. During the manufacturing steel pipe fittings, below activities shall be noted: 1, Injurious imperfections, welding defects shall be not created. Chemical Composition Grade and Marking Symbol.
