ASTM A234 Alloy Steel WP5 Buttweld Pipe Fittings
Hebei Zhongji manufacturer A234 WP5 fittings made from high quality alloy steel to ASTM A234 which can beused in various piping systems. The advantages of butt weld include:
• Welding a fitting to the pipe means that it is permanently leak proof.
• The continuous metal structure formed between the pipeand fitting adds strength to the system.
• Smoother inner surface and gradual direction changedreduce the pressure losses and turbulence and minimises the action of corrosion and abrasion.
• A welded system utilisesminimal space.
ASTM A234 covers wrought carbon steel and alloy steel fittingsof seamless and welded construction covered by the latest revision of ASMEB16.9, B16.11, MSS-SP-79, MSS-SP-83, MSS-SP-95, and MSS-SP-97. These fittingsare for use in pressure piping and in pressure vessel fabrication for serviceat moderate and elevated temperatures.
Killed steel, with forgings, bars, plates, sheet, and seamless or fusion-welded tubular products with filler metal added. 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.
After forming at an elevated temperature, fittings are cooled toa 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. Heat treatment temperatures specified are metal(part) temperatures. Heat-treated fittings are to be treated according to paragraph 7 in Specification A960/A960M.
