Product details

ASTM A53 Grade B SSAW steel pipe has a minimum yield strength of 35,000 psi (240 MPa) and a minimum tensile strength of 60,000 psi (415 MPa). Grade B pipes are suitable for applications where the focus is primarily on mechanical properties and general-purpose fluid transportation.

ASTM A53 GR.B SSAW welded steel pipe are commonly used in various applications such as water supply, gas transportation, structural projects, and general-purpose piping. They are designed to meet the specific requirements of the application and ensure reliable and efficient fluid transportation.

A53 PIPE SPECIFICATIONS
A/SA53
NPS 1/8″ – 26″
Schedules 10 through 160, STD, XH and XXH
ASTM A53 pipe (also referred to as ASME SA53 pipe) is intended 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 for forming operations involving coiling, bending, and flanging, subject to certain qualifications.

ASTM A53 pipe covers Seamless steel pipe and welded steel pipe, 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.

Materials and Manufacture
The steel for both seamless and welded pipe shall be made by one or more of the following processes: open-hearth, electric furnace, or basic-oxygen. The weld seam of electric-resistance welded pipe in Grade B shall be heat treated after welding.
