Manufacturing Process

ERW Steel Pipe

ERW steel pipe is formed from hot-rolled
coil produced in steel mill. All the incoming
coils are verified based on the test certificate
received from steel mill for their chemistry and
mechanical properties.The forming stage of
ERW pipe begins with a single-width strip. The
width of strip is roughly equal to the perimeter
of the pipe to be produced. The edges of coil
are sheared to pre-specified widths in slitting
line.The process involves uncoiling & leveling
of coils and processing the same. The lead end
of each coil is squared by shearing operation for
threading into the mill. Then this end is joined
with coil end of outgoing coil to maintain continuity
in production and reduce losses.
