Yantai Lubao has a Ф460 PQF seamless steel pipe production line with the most advanced equipment, the strongest performance and the best performance in the world, and an ARE (Accu-Roll&Expander) high-precision rolling and expanding pipe production line with independent intellectual property rights. Complete complete heat treatment, high pressure boiler tube finishing, oil pipe processing and other production lines. among them:
ARE hot rolling line:Based on the introduction of Accu-Roll rolling mill, it has been transformed into a high-precision rolling and expanding pipe production line of ARE (Accu-Roll & Expander) with independent intellectual property rights through independent integration and innovation.
PQF hot rolling line:The main main equipment is designed and manufactured by SMS Meer. Adopting the world's advanced three-roll continuous rolling process, it also adopts a full-line high-automatic control system. Such as through the installation of Carta (computer-aided rolling process application) system, HCCS (hydraulic roll gap control) system, QAS (quality assurance) and other systems, as well as L2 and L3 process computer management system, to achieve the key process and size parameters of the steel pipe ( Weight, temperature, outer diameter, wall thickness, length) are tracked, measured, and controlled in real time to ensure the production of seamless steel pipe products of first-class quality.
Heat treatment line：It is equipped with heat treatment equipment such as step type continuous heat treatment furnace and roller bottom type bright furnace with current world technology level. At the same time, it has introduced online hardness tester, magnetic flux leakage detector, ultrasonic flaw detector and hydraulic testing machine. Complete steel pipe inspection test equipment.
High-pressure boiler tube finishing line：equipped with the world's leading straightening machine, magnetic flux leakage detector, ultrasonic flaw detector, tube end ultrasonic flaw detector, tube end magnetic particle flaw detector, flat head chamfering machine, hydraulic testing machine, UV Painting equipment, etc.
General boiler tube finishing line：equipped with the world's leading technology straightening machine, magnetic flux leakage detector, ultrasonic flaw detector, tube end magnetic particle flaw detector, flat head chamfering machine, hydraulic testing machine, UV painting equipment.
Pipe processing production line：equipped with the world's leading technology in the body of wire machine, screwing machine, diameter machine, hydraulic testing machine, coupling wire machine, coupling magnetic particle flaw detector, coupling phosphating equipment.
