IS 10148 specifies hot rolled steel strip used as raw material for manufacturing welded tubes and pipes (ERW and SAW). It ensures the strip has the right chemistry, mechanical properties, and dimensional tolerances for pipe making.
Specification for hot rolled low carbon steel strip intended for manufacture of welded tubes and pipes by electric resistance welding (ERW) or submerged arc welding (SAW).
Key Values
Carbon max0.20%
Yield strength min240 MPa
Tensile strength410-540 MPa
Practical Notes
! This is the input material spec for ERW pipe mills — IS 1161 and IS 3589 pipe specs reference IS 10148 for strip quality.
! Edge quality of strip is critical for ERW welding — slit edges must be deburred and aligned.
! Carbon equivalent should be checked for weldability, especially for larger diameter SAW pipes.
