ASTM A53 SEAMLESS PIPE

ASTM A53 Seamless pipe (also referred to as ASME SA53 pipe) is used 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, subject to certain qualifications.

You can take a look of our ASTM A106 Seamless Steel Pipe, and then you can decide which type is better for your construction project.

A53 Pipe Applications

A53 Pipe Applications

ASTM A53 pipe 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.

A53 Pipe Processes

A53 Pipe Processes

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.

Hydrostatic Testing

Hydrostatic Testing

Hydrostatic inspection test pressures for plain end and threaded and coupled pipe are specified. Hydrostatic pressure shall be maintained for not less than 5 seconds for all sizes of seamless and electric-resistance-weld pipe.

Wall Thickness & Weight

Wall Thickness & Weight

The minimum wall thickness at any point shall not be more than 12.5% under the nominal wall thickness specified. And the Weight per Foot: Plus or minus 10%.
