T ube M ills & R oll F orming M achines ERW spiral welded pipe mills from China 30mm x 80 steel grade pipe production line. Spiral welded pipe mills can cover any size between 219mm and 2,800mm. It is divided into external control moulding and internal control moulding from the moulding process. In addition, it is a divided backswing type long machine unit and frontswing type short machine unit of the accumulator pit storing or fly welding tractor type. The products meet API-5L, GB711.1 and GB9711.2 standards. QINGDAO Haokun Heavy Machinery Technology Co Ltd manufactures ERW spiral welded pipe mills, hydrostatic testers, end bevelling machines and also auxiliary equipment such as slitting lines and edge milling machines. At the same time Haokun company can help pipe manufacturing enterprises to do the production process layout, planning and design. At present Haokun company’s ERW specification range is 8"–25". ERW16", ERW20", ERW24", ERW25" and other specifications of the large diameter ERW production line have completed the design and production process and Haokun has developed a JCOE1420 x The hydrostatic tester specification range is 89mm–2540mm. Haokun company has exported a 2800T/D2540 full hydraulic steel pipe hydrostatic tester and other various specifications to India, Malaysia

and Iran. End bevelling machine processing pipe diameter range can be from Ø60mm to Ø2,540mm, and it meets API-5L, API-5CT, GB9711.1 and GB9711.2 standards. The diameter range Ø60mm–339.7mm, of which the end bevelling machine is a step loading type high-speed end bevelling machine, can be used to produce petroleum casing pipe and ERW pipe production enterprises. The slitting line specification range is 1,500mm x 10mm, 1,750mm x 14mm and 2,200mm x 16mm. The specification for the 2,200mm x 16mm can meet two production methods with the longitudinal cutting striping and transecting open flatbed. These products have been used for Wuhan Iron and Steel Group. The edge milling machines with specifications 1,750mm x 16mm and 2,000mm x 25.4mm were manufactured by Haokun company have been put into use in a spiral welded pipe production line at the Shashi petroleum pipe plant. Currently, Haokun company is designing and making a high-speed strength edge milling machine for an ERW24" machine unit. Haokun company will do its best to provide the pipe industry science and tech- nology research, packaged design, manu- facturing, installation and commissioning, technology transfer, technology consultation, training and other services. Qingdao Haokun Heavy Machinery Technology Co Ltd – China The new tandem cold mill will be used for manufacturing can stock for the beverage industry. The products will comprise strip in widths of up to 2,000mm and with a minimum final gauge of 0.15mm. The mill will be designed for an annual capacity of 330,000 tons. The key components of this high-capacity mill are highly efficient roll bending systems, multizone roll cooling and a hydraulic roll adjustment system. A coil preparation station, an off-line strip inspection facility and a pallet transport system from SMS Siemag complete the rolling mill.

NORTHEAST Light Alloy Co Ltd (NELA), China, has ordered a new CVC ® plus aluminium cold rolling mill in six-high design from SMS Siemag. With the new aluminium cold rolling mill, NELA is entering modern production of high-quality aluminium strip products. In addition to various finished products, input stock for foil manufacture will be rolled on the CVC plus six-high stand. The new SMS Siemag cold rolling mill, which will constitute the central production unit of the works in Harbin, is designed for a capacity of 85,000tpy and processes incoming strips with entry gauges of maximum 8mm and widths of up to 1,900mm. The minimum final gauge is 100μm, and the maximum coil weight 21 tons. Orders for cold rolling mill received The six-high stand is equipped with CVC plus intermediate-roll shifting and with multizone roll cooling for influencing strip flatness. A hot edge spray system (HES) is provided to influence strip flatness in the strip edge area. The dry strip system (DS) installed in the exit section of the mill ensures that the residual oil on the surface of the rolled strips is kept to a minimum. A coil preparation station, a coil conveyor system and the full range of utility systems complete the mill stand. SMS Siemag has also received an order from Novelis do Brasil Ltda, Brazil, to supply a new two-stand cold rolling mill for aluminium alloys. The two-stand tandem mill is said to be the first of its type in South America.
