ASTM A53 Standard Steel Pipe Black Hot-Dipped Zinc-Coated
ASTM A53 covers seamless and welded black and hot-dipped galvanized steel pipe in NPS Nominal Pipe Size 1/8 to 26, inclusive, with nominal (average) wall thickness as given in Tables X2.2 and X2.3. Pipe having other dimensions may be furnished provided such pipe complies with all other requirements of this specification.
The dimensionless designator NPS (nominal pipe size) has been substituted in this standard for such traditional terms as "nominal diameter," "size," and "nominal size." comprehensive listing of standardized pipe dimensions is contained in American National Standard ANSI B30.10.
1.2 Pipe may be furnished in the following types and grades:
1.2.1 Types F Α Furnace-butt welded, continuous welded,
1.2.2 Types E Α Electric-resistance welded, Grades A and B, and
1.2.3 Types S Α Seamless,Grades A and B.
Pipe ordered under this specification is intended for mechanical and pressure applications and is also acceptable for ordinary uses in steam, water, gas, and air liens. It is suitable for welding, and suitable for forming operations involving coiling, bending, and flanging subject to the following qualifications: Type F is not intended for flanging.
When Types Sand E are required for close coiling or cold bending, Grade A shold be specified. This provision is not intended to prohibit the cold bending of Grade B pipe. When pipe is required for close coiling, this should be specified on the order.
Type E may be furnished either nonexpanded or cold expanded at the option of the manufacturer. When pipe is cold expanded, the amount of expansion shall not exceed 1 1/2 %of the outside diameter pipe size.
The values stated in inch-pound units are to be regarded as the standard. The metric equivalents may be approximate.
The following precautionary caveat pertains only to the menthod portion, Section 9, 10, 11, 12,13, and 14, of this specification: This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
