ASTM A53 Carbon Steel Pipe Specifications

Specifications A/SA53 NPS 1/4" - 30" Schedules 10 through 160, STD, XH and XXH

Scope

Covers Seamless and Welded, Black and Hot-Dipped Galvanized nominal
(average) wall pipe for coiling, bending, flanging and other special purposes
and is suitable for welding. Continuous-Welded pipe is not intended for flanging.
Purpose for which pipe is intended should be stated on order.
