SA178 and A178 Carbon steel ERW pipes 
QCCO STEEL Pipe Co., Ltd was established in July 1990 with registered capital of RMB570,890,000. Our company covers an area of 86,580 square meters. Our annual production capacity is 800,000 tons of steel pipes in different specifications. We are professionally engaged in manufacturing and exporting seamless steel pipe and ERW pipes, especially in casing pipe, line pipe, structural steel pipe and steel pipe for liquid service etc. 
　
1.1 This specification covers minimum-wall-thickness, ERW PIPEs made of carbon steel and carbon-manganese steel intended for use as boiler PIPEs, boiler flues, superheater flues, and safe ends.
NOTE 1 Α Type C and D PIPEs are not suitable for safe-ending for forge welding.

1.2 The tubing sizes and thickness 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 8.1 mm], inclusive, in minimum wall thickness. Tubing having other dimensions may be furnished, provided such PIPEs comply with all other requirements of this specification.
　
1.3 Mechanical property requirements do not apply to tubing smaller than 1/8 in. [3.2 mm] in inside diameter or 0.015 in. [0.4 mm] in thickness.
　
1.4 When these products are to be used in applications conforming to ISO Recommendations for Boiler Construction the requirements of this Specification A 520 shall supplement and supersede the requirements of this specification.
　
1.5 The values stated in either inch-pound units or SI units are to be regarded separately as standard. W within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must b used independently of the other. Combining values from the two systems may result in nonconformance with the specification. The inch-pound units shall apply unless the "M" designation of this specified in the order.
