ASTM A178 tubes

ASTM A178 is a specification encompassing standards for electric resistance welded tubes, commonly known as ERW SA178 Boiler Tubes. These tubes, specifically the ASTM SA178a Boiler Tubes, are manufactured with a minimum wall thickness using carbon steel alloys and carbon-manganese steel. The primary purpose of these tubes is for use in boiler flues, boiler tubes, superheater flues, and safe ends.

Key Features of SA178 Grade A Tubes:

  • Material Composition: The ASTM SA178 Grade A Electric-Resistance Welded Carbon Steel Boiler Tubes are crafted from low carbon steel, offering exceptional ductility and toughness properties.
  • Machinable and Weldable: Despite its softness, the SA178a Tube Material is highly machinable and weldable, providing versatility in various applications.
  • Cost-Effective Solution: Clients prefer Carbon Steel ASTM A178 Tubing for its cost-effectiveness, making it an economical piping solution.

All grades of ASTM-specified SA178 Boiler Tubes undergo a crucial heat treatment after welding. Following this, the SA 178 Gr A ERW Boiler Tubes are carefully cooled. Grade D and SA178c Carbon-Manganese Steel Boiler Tubes must adhere to strict requirements related to tensile properties, including tensile strength, yield strength, and elongation properties.

Chemical Requirements and Testing:

  • Chemical Conformity: All four grades (a, b, c, and d) of the SA178 Boiler Tube must conform to the chemical requirements specified in the ASTM A178 standard.
  • Testing Procedures: Each grade of ASTM A178 material undergoes a series of tests, including flange, flattening, tension, reverse flattening, and hydrostatic or non-destructive electric tests.

SA178 Tubing Sizes and Thicknesses:

  • Diameter Range: SA178 tubing sizes typically range from 1⁄2 to 5 inches [12.7 to 127 mm] in outside diameter. This versatility allows for adaptability to a variety of boiler systems.
  • Wall Thickness: The specified wall thickness falls within the range of 0.035 to 0.360 inches [0.9 to 9.1 mm], inclusive, ensuring a balance between structural integrity and thermal efficiency.

Every tube manufactured under the ASTM A178 Standard undergoes rigorous quality checks, adhering to the highest industry standards. Our commitment to excellence extends beyond meeting minimum requirements – we strive to deliver products that exceed expectations.
