Carbon / Alloy Steel Seamless Plant
HMTL has a dedicated plant of 13,500 sq. meter of covered area for manufacturing cold drawn of Carbon & Alloy Steel Tubes/pipes. Cold finished Tubes / Pipes are produced out of quality seamless hollows produced in house in UNIT-II. Seamless hollows are either cold pilgered over pilger mills or drawn over draw benches using precision tooling (dies & plugs) to achieve perfect dimensions and smooth surfaces.
Drawn/pilgered tubes are subjected to heat treatment, straightening and surface treatment. Finished tubes/pipes undergo various testing as per the specification/customer’s requirements followed by marking and packing.
