The seamless steel pipe mill owns a production line of advanced level with Italian Danieli 100 tons ultra-high power electric steelmaking, Arc continuous casting billet and round billet; a production line of Germany SMS Meer Group Φ258 PQF three-roller tandem rolling tube hot rolling; a converted Φ100ASSEL three-roll hot rolling production line; Two lines for steel tube heat treatment; Three processing lines for oil well steel pipe thread. The overall equipped level of company lies in the world's first class.
The outside diameter of seamless steel pipe specifications is from 21.3 mm to 273 mm, with thickness from 2.11 mm to 40 mm.
Tapered roller puncher(锥形辊穿孔机)
The first process for processing solid billet into seamless steel pipe is perforation process. High-performance tapered roller puncher can produce tubular billet with very thin tube wall, which brings advantages for subsequent seamless steel pipe production process.
PQF Tandem pipe mill(PQF 连轧管机)
On three-roller rack with hydraulic roll gap adjustment of PQF tandem pipe mill, the tubular billet is rolled into pierced billet by synchronized retained mandril, and the result is a constant high quality. After the rolling process finished, the pierced billet is immediately dropped from the mandril along the production line direction.
Stretch-reducing mill and sizing mill(张力减径机和定径机)
In the last step, the seamless steel pipe is rolled on stretch-reducing mill/sizing mill with many racks to the desired diameter sizes to control precision.
The welded steel pipe mill has 3 modern SAWL production lines, with the annual production capacity of 320000 tons; 9 modern SAWH production lines,with the annual production capacity of morn than 400000 tons; 2 modern HFW production lines, with the annual production capacity of 200000 tons; 2 large cross-section hollow section and cold-formed steel machine production lines, with the annual production capacity of 200000 tons; 2 3PE internal & external anticorrosive steel pipe production lines with annual production capacity of 3 million square meters. The products are widely used in the area of petroleum, petrochemical, natural gas, shale gas, pulp, water transportation and large steel structure, etc
