A234 WPB PDF

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.

The WPB is not short hand for any process. Copper Nickel Pipe Fittings.

When desired, one or more of these supplementary requirements may be specified in the order. The fittings in question are manufactured in the same manner as the companion pipe for this specification. Forging fittings Carbon content 0. The sum of Cu, Ni, Cr, and Mo shall not exceed 1. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other.

Alloy Steel Pipe Fittings. For each reduction of 0. In these standard Grade WPB is the most common material used for medium and high temperature pipelines. It covers steel fittings of seamless and welded types. ASTM A fittings material consist of killed steel, forgings, bars, plates, seamless or HFW fusion welded pipe products, with filler metal added.

Within the text, the SI units are shown in brackets. ASTM A epb steel pipe fittings have been widely applied in pipeline systems, it includes carbon and alloy steel material. The cooling rapid shall be not more than in the air.

ASTM A234 WPB Standard Specification

Steel Wb fittings are applied in pressure pipelines and in pressure vessel fabrications. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Hydrostatic test, hardness qpb, tensile test etc.

Copper, Nickel, Niobium and Molybdenum sum content shall not exceed 1. 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.

ASTM A WPB Standard Specification | Sunny Steel Enterprise Ltd.

So to complete these activities, steel pipe fittings will be applied. These fittings are for use in pressure piping and in pressure vessel fabrication for service at moderate and elevated temperatures. Whether you’ve got a large construction project, or need parts for industrial machinery, our team of steel fabrication consultants will ensure that your project is provided with the parts you need, when you need them.

Yield strength, min, Ksi [MPa] 0. 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. Wob values from the two systems may result in nonconformance with the specification. Duplex Steel A34 Fittings. SMO Pipe Fittings. 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. Or the processes of combination of two or more of these operations. Within the text, the SI units are shown in brackets. Chemical Composition Grade and Marking Symbol.

It a24 simply an identifier developed by ASTM. It shall be noted that, ASTM A specification does not cover cast welding fittings or fittings machined from castings. The maximum carbon equivalent C. Mostly these fittings includes steel elbow 45 or 90 degree bendtee, reducer concentric or eccentric reducercross, caps, nipple, flanges, gasket, studs and etc. ASTM A standard covers steel fittings of seamless and welded types.

ASTM A234 Carbon and Alloy Steel Pipe Fittings

To get a higher pressure ratings, better strength, good corrosive resistance, and longer durability. Alloy steel pipe fittings includes buttweld fittings, alloy steel long radius bend, alloy steel forged fittings and so on.

Stainless Steel Pipe Fittings. 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 aa234 raw material from welded steel pipes.

Note the reference below. W means weldable, P means pressure, B is 2a34 b, refer to the minimum yield strength. Steel pipe fittings manufacturing forming processes The manufacturing processes for pipe fittings includes forging and shaping operations. Welded A WPB pipe fittings mean the large sizes fittings which are pieces welded from steel plates.

In very large sizes, the fittings may be manufactured in pieces and welded together as is the case for many large fittings. The regular fittings of A WPB pipe fittings are elbows, tees, reducers, caps, z234.
