Type E is furnished either nonexpanded or cold expanded at the option of the manufacturer. The values stated in either SI units or inchpound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. | SPECIFICATION FOR PIPE STEEL BLACK AND HOT-DIPPED ZINC-COATED WELDED AND SEAMLESS SA-53 SA-53M 01 Identical to ASTM Specification A 53 A 53M-99 except for 00901X11 diriercnece in Note 6 and 1. Scope This specification covers seamless and weeded black and hot-dipped galvanized steel pipe in NPS 14 to 26 Note inclusive with nominal wall thickness Note 2 as given in Table and Table . NOTE The im i o n s designator NPS nominal pipe size DN diameter nominal has been substituted in this standard for such traditional terms as nominal diameter siee and nominal size. NOTE 2 The term nominal wall thickness has been assigned for the purpose of convenient designation existing in name only and is used to distinguish it from the actual wall thickness which may vary over or under the nominal wall thickness. This specification covers the foolowing types and grades Type F Furnace-butt welded continuous welded Grade A Type E Electric-resistance welded Grades A and B and Type S Seamless Grades A and B. NOTE 3 See Appendix X for de nitions of types of pipe. Pipe ordered under this specification is i mended for mechanical and pressure applications and is also acceptable for ordinary uses in steam water gas and air lines. It is suitable for welding and suitable for forming operations involving coiling bending and flanging I tjj c t to the foltowing quaiifications Type F is not intended for flagging. When Types S and E are required for close coiling or cold bending Grade A is the preferred grade. This provision is not intended to prohibit the cold bending of Grade B pipe. Type E is furnished either nonexpanded or cold expanded at the option of the manufacturer. The values stated in either SI units or inchpound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents therefore each system shall be used independently of the other. Combining values from the two systems
