ASME SA178 GR.A Boiler Steel Pipe For Heat Exchanger, Superheater and Watertube Boiler Applications
Description
ASME SA178 Boiler Steel Pipe is a standard for Electric Resistance Welded (ERW) Carbon Steel & Carbon-Manganese Steel Tubes, primarily used in boilers, boiler flues, superheaters, and heat exchangers due to their high strength, reliability, and cost-effectiveness in high-temperature, high-pressure steam generation systems, available in Grades A (low carbon), C (medium carbon), and D (carbon-manganese). These tubes are formed from flat-rolled steel, welded, heat-treated, and undergo rigorous flattening, flaring, and pressure tests to ensure performance.
