Professional management of pipe size: 5mm * 1mm-1020mm * 200mm steel pipes, cold-rolled seamless steel pipe outer diameter 22mm-127mm, diameter 127mm-600mm, wall thickness of 16mm-100mm, outer diameter precision ± 0.5% of Jiangsu 37mn5 steel pipe, wall accuracy of ± 5% thick hot-rolled seamless steel pipe, 16Mn outer diameter 400-1600mm, wall thickness 20-60mm thick-walled large-diameter coil tube can be cut to length to 16 meters and a variety of seamless pipe, Shaped seamless steel pipe etc. standing steel types are where 37mn5 20 # seamless steel pipe, 45 # seamless 37mn5 steel pipe, cold drawn seamless steel pipe, large diameter thick-walled seamless steel pipe, seamless steel pipe plant in Shandong, large-diameter seamless steel tubes, thick-walled seamless steel pipe, hot-rolled seamless steel pipe, structural seamless steel pipe, fluid seamless steel pipes, hydraulic seamless steel tubes, electrical seamless steel pipe, seamless steel pipe transport of oil, fertilizer equipment seamless steel pipe, coal seamless steel pipe, stainless steel seamless pipe, chemicals seamless steel pipe, seamless steel pipe plant for textile machinery production and processing project is scientific proof, in strict accordance with relevant national policies for the construction industry, in line with the national environmental policy, the use of energy-saving related equipment and other advanced technologies. The main products are oil casing, oil pipe, hydraulic prop tube, pressure container tube, automotive tube, pipe and other varieties military specifications for 180mm-426mm × 16-80mm, the market prospect is considerable. Technological features of the project: First, this unit ASSEL rolling machine is currently the largest domestic three-roll rolling machine; the second is the three-roll mandrel pipe mill using mandrel pre-wear and limitations of small cycles, this Technology use for domestic initiative in a three-roll rolling machine unit, the larger the rod to reduce time and improve wear life 37mn5 mandrel steel pipe Which is better, to ensure the internal quality of steel; the third is that the unit uses three computer-controlled production Process automation system can achieve a predetermined process parameters, automatic adjustment and accident diagnosis function, regardless of production processes, equipment or automation equipment belong to the international advanced level; Fourth, the use of domestic design and manufacture of the unit, save and invest, breaking the long-term foreign technique monopoly; five of the unit mainly in the production of large diameter thick-walled seamless steel tubes, particularly suitable for the production of high-alloy seamless steel pipe, to fill gaps in the market.
