We are one of the biggest manufactures of stainless steel & duplex steel & alloy steel tubes and pipes in China. With development more than 20 years, we have accumulated a great many clients all around the world and Yuhong products also won the great praise among the customers.

 

ASTM A178 Standard covers minimum-wall-thickness, 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.

 

SA178 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 0.360 in. [0.9 to 9.1 mm], inclusive, in minimum wall thickness. Tubing having other dimensions may be furnished, provided such tubes comply with all other requirements of this specification.

 

Applications:

 

ASTM A178 tubes are a kind of frequently-used tubes in our life, they are mainly used in manufacturing heating pipelines, containers, coal-saving devices, superheaters, arch superheated tube, airway tube etc.
