ASTM A234 WP22 Pipe Fittings are widely used in piping systems that operate under high pressure and elevated temperature conditions. These alloy steel fittings are known for their excellent strength, weldability, durability, and resistance to corrosion. They are available in a variety of sizes, shapes, and configurations to meet the specific requirements of different industrial applications. ASTM A234 WP22 is a standard specification under which these fittings are manufactured. The alloy steel used in producing these products is thoroughly tested and inspected before being utilized in the manufacturing process. Different types of fittings are available such as seamless, fabricated, and welded fittings.

Specification for ASTM A234 WP22 Pipe Fittings
ASTM A234 WP22 standard covers wrought alloy and carbon steel fittings of seamless and welded construction. These fittings are manufactured according to dimensional standards such as ASME B16.9, B16.11 and MSS-SP-83, MSS-SP-95, and MSS-SP-79. ASTM A234 WP22 pipe fittings are commonly used for pressure piping systems and pressure vessel fabrication services operating at moderate to elevated temperature conditions.

Process of manufacturing
These ASTM A234 WP22 Pipe Fittings are manufactured using killed steel, bars, plates, and welded tubular products with appropriate filler metals when required. The shaping and forming operations include processes such as pressing, hammering, upsetting, bending, fusion welding, extruding, and machining. After the fittings are formed at elevated temperatures, they are cooled under controlled conditions below the critical temperature range to ensure proper metallurgical properties. Heat treatment is performed in accordance with ASTM A960 / A960M standards. The fittings undergo various inspection and testing procedures and are packed according to international packaging standards for safe transportation.
