A178 Carbon Steel Tube
A178 Welded Pipe Description
A178 welded pipe is a resistance welded carbon steel boiler pipe manufactured in accordance with ASTM A178 standard. It is specially used for heat exchange equipment under high temperature and high pressure conditions. Analysis of A178 standard:
1.This specification 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.
Note 1-Type C and D tubes are not suitable for safe-cnding for forge
welding.
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 0.360 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.
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.
4. Optional supplementary requirements are provided and when desired, shall be so stated in the order.
5. The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be 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 specification is specified in the order.
