ASME A234 WPB 90 deg LR SR Elbow,ASTM A234 WPB ELBOW ASME B16.9

ASTM A234 WPB  ELBOW is a common grade for 90 degree long radius elbow, which is one of the highly demanded. They available in a large size and thickness range. They have a good performance and suffices most industrial pipeline needs.

As a experiened ASTM A234 WPB  ELBOW,pipe fittings manufacturer in china,We produce high quality ASTM A234 WPB  ELBOW,Tee,Reducer,caps 

A234 WPB PIPE FITTINGS are most common grade in the pipeline connection.which are made from Seamless pipe A106 Grade B or API 5L grade B line pipes.

90 degree elbow is used to be installed between two lengths of pipe or tube allowing a change of 90 degree direction,usually these elbows distinguished by connection ends, The ends may be machined for butt welding , threaded , or socketed , so the 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

Standard Specification for Piping Fittings of Wrought Carbon Steel and Alloy Steel for Moderate and High Temperature Service

Abstract

This specification covers wrought carbon steel and alloy steel fittings of seamless and welded construction. These fittings are for use in pressure piping and in pressure vessel fabrication for service at moderate and elevated temperatures. The material for fittings shall consist of killed steel, forgings, bars, plates, seamless or fusion-welded tubular products with filler metal added. Forging or shaping operations may be performed by hammering, pressing, piercing, extruding, upsetting, rolling, bending, fusion welding, machining, or by a combination of two or more of these operations. The forming procedure shall be so applied that it will not produce injurious imperfections in the fittings. Fittings, after forming at an elevated temperature, shall be 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. The fittings shall be subjected to tension test, hardness test, and hydrostatic test.

ASTM A234 WPB  Heat treatment

1 Hot-formed WPB, WPC, and WPR fittings upon which the final forming operation is completed at a temperature above 1150 °F [620 °C] and below 1800 °F [980 °C] need not be heat treated provided they are cooled in still air.

7.2.2 Hot-formed or forged WPB, WPC, and WPR fittings finished at temperature in excess of 1800 °F [980 °C] shall subsequently be annealed, normalized, or normalized and tempered. Hot-forged fittings NPS 4 or smaller need not be heat treated.

7.2.3 WPB, WPC, and WPR fittings over NPS 12, produced by locally heating a portion of the fitting stock to any temperature for forming, shall be subsequently annealed, normalized, or normalized and tempered. Fittings such as elbows, tees, header tees, reducers and lap joint stub ends with a carbon content less than 0.26 %, NPS 12 and under, shall not require heat treatment after forming a locally heated portion of the fitting.

7.2.4 Cold-formed WPB, WPC, and WPR fittings, upon which the final forming operation is completed at a temperature below 1150 °F [620 °C], shall be normalized, or shall be stress relieved at 1100 to 1275 °F [595 to 690 °C]. 7.2.5 WPB, WPC, and WPR fittings produced by fusion welding and having a nominal wall thickness at the welded joint of 3 ⁄4 in. [19 mm] or greater shall be post-weld heat treated at 1100 to 1250 °F [595 to 675 °C], or in accordance with 7.2.6. 7.2.6 At the option of the manufacturer, WPB and WPC fittings produced by any of the methods in Section 6 may be annealed, normalized, or normalized and tempered.
