ASTM A WPB is the Standard Specification for Piping Fittings of Wrought Carbon Steel and Alloy Steel for Moderate and High Temperature Service. A WPB steel pipe fittings mean the pipe fitting which material is ASTM A WPB,they are used for the pressure piping systems of moderate and high. We may ofen encounter the material of ASTM A WPB,It is a common kind of carbon steel. Yesterday I met the material of A WPC, want to.

Octal is located in China recognized as a leading supplier, distributor, and manufacturer union in providing piping solutions for oil and gas company.
Duplex Steel Pipe Fittings. SMO Pipe Fittings. Stainless Steel Pipe Fittings. Steel Pipe fittings are applied in pressure wpv and in pressure vessel fabrications. The regular fittings of A WPB pipe fittings are elbows, tees, reducers, caps, cross. Forging fittings Carbon content 0. The sum of Cr and Mo shall not exceed 0.
The fittings material in this standard consist of killed steel, forgings, bars, plates, seamless or fusion-welded tubular products with filler metal added. So to complete these activities, steel pipe fittings will be applied. Now Ramesh Steel corp. A WPB is the most common carbon steel pipe fittings material.
When desired, one or more of these supplementary requirements may be specified in the order. These fittings are for use in pressure piping and in pressure vessel fabrication for service at moderate and elevated temperatures.
ASTM A234 WPB Pipe Fittings
It is widely used in oil and gas pipelines, chemical industries, power plants, nuclear power qpb, and in server conditions. Hydrostatic test, hardness test, tensile test etc. Where the wall thickness lies between two values above, the min elongation value is determined by the following equations:.
Astm A Asme B Steel pipe fittings manufacturing forming processes The manufacturing processes for pipe fittings includes forging and shaping operations. The maximum carbon equivalent C.
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. In these standard Grade WPB is the most common material used for medium and high temperature pipelines.
But the large sizes pipe fittings are commonly manufactured in pieces and welded together. z234
For each reduction of 0. ASTM A fittings material consist of killed steel, forgings, bars, plates, seamless or HFW fusion welded pipe products, with filler metal added. During the manufacturing steel pipe fittings, below activities shall be noted: Steel elbow is used to be installed between two lengths of pipe or tube allowing a change of direction,usually these carbon steel elbows distinguished by connection ends, The ends may be machined for butt weldingthreadedor socketedso the carbon steel elbows are consist of butt weld,thread elbow socket elbow and other series.
It covers steel fittings of seamless and welded types. 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.
In very large sizes, the fittings may be manufactured in pieces and welded together as is the case for many large fittings. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other.
When desired, one or more of these supplementary requirements may be specified in the order. As well as pressing, hammering, piercing, extruding, upsetting, rolling, bending, fusion welding and machining.
A Fittings : A WPB Carbon Steel Pipe Fittings Manufacturers
And no defects shall be made during the cooling procedures. Alloy Steel Pipe Fittings. Carbon Steel Pipe Fittings. It has seamless, welded and fabricated types.
ASTM A WPB Standard Specification | Sunny Steel Enterprise Ltd.
Yield strength, min, Ksi [MPa] 0. In this standard it covers the specification of elbows, tees, reducers, caps and cross, it usually adopt butt welding ends. The cooling rapid shall be not more than in the air.
The alloy steel pipe fitting is fabricated with alloy elements in such as Chrome, Molybdenum, Nickel alloy, Hastelloy alloy, Monel, Inconel, and etc. It shall be noted that, ASTM A specification does not cover cast welding fittings or fittings machined from castings.
ASTM A standard covers steel fittings of seamless and welded types. ASTM A is the standard of pipe fittings material, it indicates the materials properties of different kinds of carbon steel and alloy steel, WPB is one of the steel grade in this standard. The sum of Cu, Ni, Cr, and Mo shall not exceed 1. W means weldable, P means pressure, B is grade b, refer to the minimum yield strength. Note the reference below. Chemical Composition Grade and Marking Symbol.
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.
ASTM A standard steel pipe fittings have been widely applied in pipeline systems, it includes carbon and alloy steel material. These fittings are for use in pressure piping and in pressure vessel fabrication for service at moderate and elevated temperatures.
