ASTM – A53 Grade A (B) – Continuous or Electric Resistance Welded (ERW)
ASTM A53 WELDED AND SEAMLESS STEEL PIPE
This specification covers seamless and welded black and hot dipped galvanized steel pipe furnished in the following types and grades:
Type F. – Furnace – butt welded
Type E. – Electric – resistance welded, Grades A, B, and C.
Type S. – Seamless, Grades A, B, and C.
Pipe ordered under this specification is nominal (average) wall thick ness, suitable for welding, and suitable for forming operations involving coiling, bending and flanging, subject to the following qualifications:
(1) Type F is not intended for flanging.
(2) When Types S and E are required for close coiling or cold bend ing. Grade A should be specified. This provision is not intended to prohibit the cold bending of Grade B pipe.
(3) When pipe is required for close coiling, this should be so specified on the order
ASTM A106 SEAMLESS CARBON STEEL PIPE
FOR HIGH-TEMPERATURE SERVICE
These specifications cover seamless carbon steel pipe for high-temperature service. Pipe ordered under these specifications is nominal (average) wall and shall be suitable for bending, flanging, and similar forming operations.
Supplementary requirements of an optional nature are provided for seamless pipe intended for use in central stations having steam service pressures of 400 psi and over and high temperatures or other applications where a superior grade of pipe is required. These supplementary requirements call for additional tests to be made and when desired shall be so stated in the order.
When these products are to be used in applications conforming to ISO Recommendations for Boiler Construction, the requirements of ASTM Specification A 520, for Supplementary Requirements for Seamless and Electric-Resistance-Welded Carbon Steel Tubular Products for High Temperature Service Conforming to ISO Recommendations for Boiler Construction, shall supplement and supersede the requirements of this specification.
