Description

ASME SA-178/SA-178M ELECTRIC-RESISTANCEWELDED CARBON STEEL AND CARBON-MANGANESE

STEEL BOILER AND SUPERHEATER TUBES

The SA178 ERW pipes including Steel Grade A,C,D

1.This specification covers minimum-wallthickness,electric-resistance-welded tubes made of carbon
steel and carbon-manganese steel intended for use as boiler tubes, boiler flues, superheater flues, and
safe ends.

2.The tubing sizes and thicknesses usually furnished to this specification are 1⁄2 to 5 in. [12.7 to 127 mm]
in outside diameter and 0.035 to 0.320 in. [0.9 to 9.1mm], inclusive, in minimum wall thickness. Tubing
having other dimensions may be furnished, providedsuch tubes comply with all other requirements of this
specification.

3.Reference ASTM Standards:

A 226/A 226M Specification for Electric-Resistance-Welded Carbon Steel Boiler and Superheater Tubes
for High-Pressure Service
A 450/A 450M Specification for General Requirementsfor Carbon, Ferritic Alloy, and Austenitic Alloy Steel
Tubes
A 520 Specification for Supplementary Requirements for Seamless and Electric-Resistance-Welded Carbon
Steel Tubular Products for High-Temperature Service Conforming to ISO Recommendations for Boiler Construction.
E 213 Practice for Ultrasonic Examination of Metal Pipe and Tubing
E 273 Practice for Ultrasonic Examination of Longitudinal Welded Pipe and Tubing

A 450/A450M Test report required (Certification Section of Specification A 450/A 450M)

4.The steel for Grade D shall be killed.
5.Tubes shall be made by electric-resistance welding tubes/ERW tubing

6.The ERW metal tubes including steel grade A.C,D

7.After welding, all tubes shall be heat treated at a temperature of 1650°F [900°C] or higher and followed
by cooling in air or in the cooling chamber of a controlled-atmosphere furnace. Cold-drawn tubes shall
be heat treated after the final cold-draw pass at a temperature of 1200° [650°C] or higher.
