<> ASTM A234 is Standard Specification for steel pipe fittings includes carbon and alloy steel material for moderate and high temperature services. W means weldable, P means pressure, B is grade b ,refer to the minimum yield strength , like the astm A106 A53, Gr.B or API 5L Gr.B. 1.2 Optional supplementary requirements are provided for fittings where a greater degree of examination is desired. 1 0 obj Copyright © 2011 Sunny Steel Enterprise Ltd. All Rights Reserved After forming at an elevated temperature, fittings are cooled to a temperature below the critical range under suitable conditions to prevent injurious defects caused by too rapid cooling, but in no case more rapidly than the cooling rate in still air.
A234 WPB is the most common carbon steel pipe fittings material . 4 0 obj stream <>>> However, unless the order specifies the applicable “M” specification designation (SI units), the material shall be furnished to inch-pound units.1.5 The values stated in either inch-pound units or SI units are to be regarded separately as standard. endobj There are different varieties of pipe fittings made of various materials and available in various shapes and sizes.Our team are highly trained and experienced in servicing and producing all types of steel supplies. These fittings are for use in pressure piping and in pressure vessel fabrication for service at moderate and elevated temperatures.
ASTM A234 specification has many grades, such as WPB, WPC, WP11, WP12, WP22, WP91 and so on. endobj Heat treatment temperatures specified are metal (part) temperatures. %PDF-1.5 The source raw material of ASTM A234 WPB steel pipe fittings may be from steel pipe, such as ASTM A106 Gr.B and C. Also from steel plate, as ASTM A285 Gr.C, ASTM A516 Gr 70, ASTM A572 etc. ASTM A234 Steel Pipe Fittings Chemical Composition and Mechanical Properties ASTM 234 Grade and Marking Symbol (ASTM A234 steel pipe fittings) Chemical Composition, % C Mn P S Si Cr Mo WPB 0.30 max 0.29-1.06 0.05 0.058 0.10 min 0.40 max 0.15 max WPC 0.35 max 0.29-1.06 0.05 0.058 0.10 min … These fittings are for use in pressure piping and in pressure vessel fabrication for service at moderate and elevated temperatures. ASTM A234 WPB steel pipe fitting chemical and mechanical features.
Forging or shaping operations performed by hammering, pressing, piercing, extruding, upsetting, rolling, bending, fusion welding, machining, or by a combination of two or more of these operations.
The ASTM A234 WPB is a plain carbon steel and may be made to either coarse grain or fine grain practice. Heat-treated fittings are to be treated according to paragraph 7 in Specification A960/A960M.The regular fittings of A234 WPB pipe fittings are elbows, tees, reducers, caps, cross.A common example using welded pipe fitting is a pipe reduced by concentric reducer, welded to a weld neck flange and connected to an equipment. Combining values from the two systems may result in nonconformance with the specification.Where the wall thickness lies between two values above, the min elongation value is determined by the following equations: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 welding , threaded , or socketed , so the carbon steel elbows are consist of butt weld,thread elbow socket elbow and other series.the material is selected according to the application use such as high temperature use,sanitary fitting,regular industrial use etc.What is the manufacturing process of ASTM A234 WPB pipe fittings?In very large sizes, the fittings may be manufactured in pieces and welded together as is the case for many large fittings.The term used for the manufacturing is called “wrought” which means it is worked as opposed to being cast or forged.As to the W standing for weldable, I’m not sure that is correct since that are many, many pipe fittings that are weldable but carry designations other than a W. Note the reference below.This standard covers wrought carbon steel fittings of seamless and welded construction which are manufactured to the dimensional specifications of ASME B16.9 and B16.28. W means weldable, P means pressure, B … Its source can be steel pipe, such as ASTM, A106, Gr.C, or steel plate, such as ASTM, A285, GR.C
These fittings are primarily for use in pressure piping and in pressure vessel fabrication for service at moderate and elevated temperatures.ASTM A234 specification has many grades, such as WPB, WPC, WP11, WP12, WP22, WP91 and so on.In these standard Grade WPB is the most common material used for medium and high temperature pipelines.
