ASTM A234 WPB Standard Specification

ASTM A234 is Standard Specification for steel pipe fittings includes carbon and alloy steel material for moderate and high temperature services.

Forging is the manufacturing process of ASTM A234 WPB pipe fittings.

W = WELDABLE / wrought
P = RELATED TO P NUMBER OF ALLOY MATERIAL
B = REFER TO MINIMUM YIELD OF MATERIAL

Grades in ASTM A234

ASTM A234 specification has many grades, such as WPB, WPC, WP11, WP12, WP22, WP91 and so on.

In these standard Grade WPB is the most common material used for medium and high temperature pipelines. W means weldable, P means pressure, B is grade b, refer to the minimum yield strength.

The source raw material of ASTM A234 WPB steel pipe fittings may be from steel pipe, such as ASTM A106 Gr.B and C. Also from steel plate, as ASTM A285 Gr.C, ASTM A516 Gr 70, ASTM A572 etc.

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.

ASTM A234 Scope

1.1 This specification 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, and MSS-SP-95. These fittings are for use in pressure piping and in pressure vessel fabrication for service at moderate and elevated temperatures. Fittings differing from these ASME and MSS Standards shall be furnished in accordance with Supplementary Requirement S58 of Specification A 960/A 960M.

1.2 Optional supplementary requirements are provided for fittings where a greater degree of examination is desired. When desired, one or more of these supplementary requirements may be specified in the order.

1.3 This specification does not cover cast welding fittings or fittings machined from castings. Cast steel welding fittings are governed by Specifications A 216/A 216M and A 217/A 217M.

1.4 This specification is expressed in both inch-pound units and in SI units. However, unless the order specifies the applicable “M” specification designation (SI units), the material shall be furnished to inch-pound units.

1.5 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.

GENERAL NOTE: All values are maximum unless otherwise indicated.

Mechanical properties of ASTM A234

Tensile Requirements	WPB	WPC, WP11CL2	WP11CL1	WP11CL3
Tensile Strength, min, ksi[MPa]	60-85	70-95	60-85	75-100
(0.2% offset or 0.5% extension-under-load)	[415-585]	[485-655]	[415-585]	[520-690]
Yield Strength, min, ksi[MPa]	32	40	30	45
Yield Strength, min, ksi[MPa]	[240]	[275]	[205]	[310]

Where the wall thickness lies between two values above, the min elongation value is determined by the following equations:

Longitudinal E=48t+15.00
Transverse E=32t+10.00
E = elongation in 2in [50mm], %
t = actual thickness of specimen, in [mm]
