Shandong Panjin Steel Pipe Manufacturing Co., Ltd. was established in 2017 with a registered capital of 600 million yuan. The company is located in Hou Town, Shouguang City, Shandong Province, close to Shandong Luli Iron and Steel Co., Ltd. and Shandong Panjin Forging Machinery Co., Ltd., 20km from Yangkou Port and Weifang Port in the north, and 5km from the Rongwu highway intersection. The geographical position is superior and the transportation is convenient. The company is mainly equipped with six modern continuous rolling pipe production lines, including two Φ159 two-high continuous rolling lines, two Φ180 three-high continuous rolling lines, and two Φ273 three-high continuous rolling lines. The annual production capacity of hot-rolled pipes is 3 million tons. With complete specifications, it can produce high-quality seamless pipe products in the range of Φ32～Φ356×3.5～40mm.

       1. Unique process design

       Relying on the advantages of Shandong Luli Iron and Steel Co., Ltd. and Shandong Panjin Forging Machinery Co., Ltd. in tube billet steel production, the design adopts the tube billet hot charging and hot delivery process, which can greatly shorten the billet heating time and reduce energy consumption; a walking heating furnace is used for supporting The mode of two continuous rolling mills achieves a substantial increase in output and good heating quality; the entire line adopts advanced technology and production equipment at home and abroad to achieve high yield, low consumption and high quality.

       2. Complete energy-saving and environmental protection facilities

       In order to meet the country's high requirements for energy-saving and environmental protection projects in the new era, the company has focused on supporting investment in all types of environmental protection facilities from the beginning of project planning and design. All types of energy-saving and environmental protection facilities are complete and advanced, which can fully achieve energy-saving and environmental protection control goals.

       3. High degree of equipment automation

       The whole line is designed for three-level automation control of drive and detection level, basic automation level, and process control level. Through the configuration of linear displacement sensors, pressure sensors, position encoders, rotary encoders, hot metalizers and other components, the full line of automatic production from blanks, piercing, rolling and hot rolling can be realized.

       4. The product quality is good

       The continuous rolling mill production line is equipped with roll gap hydraulic pressure reduction system HCCS, continuous rolling head and tail sharpening TS system and tension head and tail control CEC system, which can achieve wall thickness accuracy ±5% to ±7% and outer diameter accuracy ±035 %, the internal and external surfaces are of good quality.
