Carbon steel fittings used in either moderate or high temperature services are covered by the ASTM A234 Specification. The specified steel fittings covered include both seamless and welded kind of ASTM A234 WPB Elbow. Usually, both the carbon as well as alloy steel pipe fittings that are produced under this specification find use in pressure pipelines and in pressure vessel fabrications. The different kinds of fittings that could be produced under this specification includes Carbon Steel A234 WPB SCH 80 Elbow, tees, reducers, caps and crosses. Although these fittings normally adopt butt welding ends. A fitting used in any industry performs the function of changing either the rate of flow or the direction of the flow of media. In the instance of a Buttweld SA234 WPB Elbow, the change provided is with regards to the change in direction.

The material for these fittings consists of killed steel, bars, forgings, plates, seamless or HFW, which is also referred to as fusion welded pipe products, with an added filler metal.

Some of the more conventionally used elbows are angled at 22.5 degrees, 45 degrees and 90 degrees. For instance, the A234 WPB Buttweld Elbow 45 Degree is to change the flow of media, at an angle of 45 degrees. While all three i.e. 22.5 degrees, 45 degrees as well as the Elbow 90 A234 WPB are commonly used across several industries, most manufacturers today, cater to the buyer’s requirement by customizing the angle of the elbow fitting in addition to the alloy grade used and the surface treatment given to the respective fitting. The SA234 WPB SR And LR Elbow are widely used in industries like the oil and gas pipelines, power plants, chemical industries, nuclear power sites, in addition to being used in severe conditions.
