Product Description Welded Pipe Mill The plate in certain width after slitting line and stripping is unfolded and leveled. Then, they are sent into forming machine. Used the roller, the plate is bent into pipe state. The edge of the steel plate is melted by making use of the proximity effect and skin effect of high frequency current. Then, the plate is extruded and welded into the pipe by extruding roller. Straight seam welded pipe mill also is called ERW mill.The forming styles of straight seam welded pipe can be divided into roll forming, flexible forming, full auto flexible forming. The mill developed by our company adopts roll forming when having small diameter (Φ≤114). Flexible forming or full automatic flexible forming is adopted when having middle or large diameter(Φ≤711).In recent year, our company developed the precise control forming. The advantage of this kind forming is to guarantee the excellent forming quality in rough forming section through the precise control. Then it is no need to have the repair management in precise forming section. Therefore, the precise forming in this forming method does not need to change the roller. All the forming section does not need to change the roller, which solves the problem of the change in precise forming section and non-change in rough forming section. Therefore, it saves the roller investment and decreases the time of roller changing. Besides, during the diameter changing, all are controlled by industrial computer. The roller will automatically reach the position by inputting the pipe diameter, pipe wall thickness, material and other parameters. It largely improves the mill efficiency and pipe qualified rate. This forming method is suitable for medium and large mill from 219mm to 711mm, which saves the investment and improves the efficiency.According to the pipe application, the ERW line can be divided to API standard pipe mill and national standard mill.API standard straight seam HF welded pipe mill introduction is mainly used for producing the high grade pipe such as oil, gas delivering and casing pipe in the oil well. These high grade pipes strictly require the pipe material and pipe quality. This kind of straight seam HF welded pipe mill has IF annealing, air cooling roller rail, UT detector, high pressure hydrotester, diameter drifter and other detect equipments and art craft.National standard mill is mainly used for manufacturing the low pressure fluid pipe and structure pipe.ModelNo.ModelSpecification(mm)Speed(m/min)Thickness(mm)Capacity(kw)Area(M2)1HNBXG-219Φ89~Φ2190.1~1.82.0~10~10024×2002HNBXG-273Φ89~Φ2730.1~1.82.0~10~12024×2003HNBXG-325Φ140~Φ3250.1~1.52.0~12~25024×2004HNBXG-355Φ140~Φ3550.1~1.52.0~12~25024×2005HNBXG-406Φ165~Φ4060.1~1.52.0~12~25024×2006HNBXG-426Φ165~Φ4260.1~1.52.0~14~30024×3007HNBXG-508Φ219~Φ5080.1~1.53.0~14~35030×3008HNBXG-610Φ273~Φ6100.1~1.53.0~14~35030×3009HNBXG-630Φ273~Φ6300.1~1.53.0~14~40030×30010HNBXG-660Φ273~Φ6600.1~1.53.0~14~40030×30011HNBXG-711Φ325~Φ7110.1~1.53.0~14~40030×400Technical Feature1). Forming Machine without Roller Changing TechnologyThe unit adopts the world's most advanced molding machine, on the basis of the rough forming machine does not need to replace the roll, and developed the fine forming machine that does not need to replace the roll, so that the entire forming machine does not need to replace the roll.In this way, roll changing time is reduced and production efficiency is improved, which makes the production of multi-specification and small-batch orders possible.2). Rapid replace roller sizing machineOur machine set adopts the technology of rapid roll replacement with shafting lateral pull-out. and the spare shaft system of the installed roll is fed into the frame. In this way, roll changing time is reduced and production efficiency is improved, which makes the production of multi-specification and small-batch orders possible.3). PC control to change specificationsPrevious technology, when changing specifications of the roll adjustment, require highly skilled adjustment workers to do so. Due to the uncontrollable human factors, the unit's reject rate is relatively high and the adjustment time is relatively long, which seriously affects the unit yield and production efficiency. Our unit, the establishment of a comprehensive database, changing specifications, only need to input parameters such as diameter, wall thickness, the computer is called roll to adjust the location data of database, the computer will drive roll automatically stop after arrived in correct position, directly into the belt will be able to production, reduce the adjustment time and errors, reduce the rejection rate when the leader. Such adjustment technology, combined with the machine that does not need to replace the roll and the sizing machine that rapidly changes the roll, the unit can change the specification within 2 -3 hours, in the world leading position.Working processPreparing Coil →Loading Coil→ Uncoiling→ Detaching head→ Pinching & Leveling Machine →Cutting& Butt Welding Platform→ Forming Machine→ Welding→ Leveling Inner Weld of Steel Pipe → Polishing Outer Weld of Steel Pipe → Sizing 1 → On-line Solid Solution → Sizing 2 →Cutting with a fixed length band saw → Feeding the pipe after saw No.Name 1Loading Coil Machine 2Uncoiling Machine 3Head Remover 4Pinching Leveler 5Butt Welding Platform 6Forming Machine 7Shared Roller 8Welding Device 9PPTT-500 Double Side Welding Machine 10Inner Welding Seam Grinding machine for steel pipes 11Outer Welding Seam Grinding Machine for Steel Pipe 12Sizing Machine 1 13Online Solid Solution Equipment 14Sizing Machine 2 15Cut to Length Machine 16Customized Band Saw 17Feeding Out Pipe Roller Table After Sawing 18xxxmm Roller 19xxxmm Roller 20Hydraulic System 21Electrical Control System Installation and CommissioningThe seller provides on-site installation and guidance services. The seller's visas, round-trip airfare, meals, and accommodation are the responsibility of the buyer, and the seller's staff will pay USD 100 per person per day.Term of PaymentWithin 7 days after the contract is signed, 30% of the total amount of the contract will be prepaid, and the contract will take effect; the contract will be effective for two months, paying 20% of the progress payment; before delivery, 45% of the total contract amount will be paid. 5% will be paid when Finished installation and commission.
