What is A234 WPB material?

WPB is a steel grade in which W stands for weldable, B is grading B and P stands for pressure. Thus it is referring minimum yield strength. ASTM A106 A53, API 5L grade B A234 WPB and Grade B is common carbon steel material of pipe fitting., The ASTM A234 A234M is a standard 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.

 

Tests and Examinations

ASTM A234 WPB or WPC fittings shall be furnished free of injurious imperfections such as dents, crackings, scratches, etc. Rigorous dimensional examination and visual inspection shall be performed. PMI heat analysis and tensile tests shall be performed to determine its chemical composition and mechanical properties. When required, other tests including Liquid Penetrant Inspection, Magnetic Particle Examination, Eddy-Current Test and Ultrasonic Test may be performed.

 

Application

  • Fittings To Connect Pipe & Tubes in Petroleum, Power, Chemical, Construction, Gas, Metallurgy, Shipbuilding etc
  • ASTM A234 WPB Sch 10 fittings are an economical alternative for lower-pressure applications.
  • ASTM A234 WPB Sch 40 fittings have a thicker wall for higher-pressure applications.
