Hot-rolled production line

At present, we have 3 sets of hot-rolled seamless steel pipe production lines with an annual production capacity of 1.35 million tons. The physical and chemical laboratory conducts various physical and chemical tests on steel pipes, and is equipped with eddy current flaw detectors, magnetic flux leakage detectors and ultrasonic flaw detectors. It is used for high, medium and low pressure seamless steel pipes and oil casings. All-round inspection measures can meet various standard test and inspection requirements for steel pipes.

Φ114 two-roll continuous rolling pipe production line (MPM) : Φ32 ~ Φ114 × 3 ~ 30 mm

Φ180 three-roll continuous rolling pipe production line (PFQ) : Φ108 ~ Φ219 × 5 ~ 40mm

Φ273 three-roll continuous rolling pipe production line (PFQ) : Φ177.8 ~ Φ356 × 6 ~ 50.0 mm

In addition, there are 12 thermal expansion production lines, the production size range is: Φ356 ~ Φ1200 × 8 ~ 50.0 mm)

Φ114 two-roll continuous rolling pipe production line (MPM)

The main equipment of the two-roll continuous rolling line is composed of "conical roller piercing machine + 6-stand PQF continuous rolling mill + 14-stand micro tension setting machine". The unit mainly produces        high-quality oil pipes with large diameter-to-wall ratio (D/S), Line pipe, structural pipe, boiler pipe, product specification Φ32～114×3～30mm, designed annual output of 300,000 tons
