PRODUCT LINES
EQUIPMENT & PROCESS CAPABILITY

Production and inspection equipment under one roof.

The integrated layout supports production planning through final testing while maintaining heat and material traceability across all manufacturing routes.

MPM continuous rolling mill

Continuous hot rolling for controlled pipe geometry, wall uniformity and production throughput.

Elongator and sizing mill

Hot-process equipment supporting piercing, elongation and dimensional control to finished sizes.

Cold drawing and pilger mill

Cold reduction routes for tighter dimensions, higher strength and improved surface condition.

Heat treatment furnaces

Normalizing, annealing, quench-and-temper, and bright annealing for required structure and properties.

Hydrostatic testing

Automatic pressure-integrity testing for applicable products and standards up to test pressures per specification.

NDT — ECT, UT, MPI

Eddy current, ultrasonic and magnetic particle examination for surface and volumetric discontinuity detection.
PROCESS FLOW

Hot Finished Seamless (HFS)

From billet inspection through piercing, rolling, heat treatment and testing to dispatch — 18 controlled stages under one production system.
