ASTM A234 WPB-S ELBOW 45/90 DEGREE CARBON STEEL B16.9 BLACK PAINTING

 

Steel elbow is used to be installed between two lengths of pipe or tube allowing a change of direction,usually these carbon steel elbows distinguished by connection ends, The ends may be machined for butt welding , threaded , or socketed , so the carbon steel elbows are consist of butt weld,thread elbow socket elbow and other series.the material is selected according to the application use such as high temperature use,sanitary fitting,regular industrial use etc.

  • ASTM A234 fittings material consist of killed steel, forgings, bars, plates, seamless or HFW (fusion welded) pipe products, with filler metal added.
  • ASTM A234 standard covers steel fittings of seamless and welded types. ASTM A234 Pipe fittings are applied in pressure pipelines and in pressure vessel fabrications.
  • ASTM A234 / A234M-07 Standard Specification for Piping Fittings of Wrought Carbon Steel and Alloy Steel for Moderate and High Temperature Service

 

ASTM A234 Scope:

 

  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.
  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.
  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.
  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.
  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.

Notes:

  • For each reduction of 0.01% below the specified C maximum, an increase of 0.06% Mn above the specified maximum will be permitted, up to a maximum of 1.35%.
  • The sum of Cu, Ni, Cr, and Mo shall not exceed 1.00%.
  • The sum of Cr and Mo shall not exceed 0.32%.
  • The maximum carbon equivalent (C.E.) shall be 0.50, based on heat analysis and the formula C.E.=C+Mn/6+(Cr+Mo+V)/5+(Ni+Cu)/15.

 

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
[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]
