A234 WP9 Fittings

Hebei Haiwei manufacturer A234 WP9 fittings made from high quality alloy steel to ASTM A234 which can be used 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 pipe and fitting adds strength to the system.

• Smoother inner surface and gradual direction changed reduce the pressure losses and turbulence and minimises the action of corrosion and abrasion.

• A welded system utilises minimal space.

ASTM A234 WP9 Specification

Scope 

ASTM A234 covers wrought carbon steel and alloy steel fittings of seamless and welded construction covered by the latest revision of ASME B16.9, B16.11, MSS-SP-79, MSS-SP-83, MSS-SP-95, and MSS-SP-97. These fittings are for use in pressure piping and in pressure vessel fabrication for service at moderate and elevated temperatures.

Process

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.

Heat Treatment

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. Heat treatment temperatures specified are metal (part) temperatures. Heat-treated fittings are to be treated according to paragraph 7 in Specification A960/A960M.
