About Nantong Shengli Heavy Machine Manufacturing

Nantong Shengli Heavy Machine Manufacturing Co., Ltd was founded in 2003 in Hai'an City, in the Nantong area of Jiangsu Province. The company designs and builds heavy sheet and plate forming machinery. Its main machines are 3-roll and 4-roll plate rolling machines, which bend steel plate into cylinders and cones for tanks, towers, pressure vessels and pipes.

Shengli began building 4-roll plate rolling machines for wind tower production in 2008, and has since developed complete LSAW (longitudinal submerged arc welded) pipe mill lines, including JCOE and CEO forming methods. These lines make large-diameter straight seam pipe for oil, gas and water pipelines, with plate up to 50 mm thick and pipe lengths up to 12.5 metres. It also builds 6 metre and 12 metre pipe bending machines for the same industry.

For tank and vessel makers, Shengli offers head flanging and spinning machines and head pressing machines that form dished ends. Its range also includes section bending machines, plate levelling machines and hydraulic presses. The company sells direct from the factory, has its own quality inspection department, and welcomes buyers to inspect machines before delivery.

Who Nantong Shengli Heavy Machine Manufacturing suits best

Shengli suits heavy fabricators rather than sheet metal shops. That includes wind tower makers, pressure vessel and storage tank builders, and companies setting up large-diameter pipe production for pipelines. A buyer who needs both the plate rolling machine and the head forming machines for a tank or vessel line can get them from one factory. Shengli is also one of the few suppliers on MachineMatcher offering complete LSAW pipe mill lines.

Frequently asked questions

Where is Nantong Shengli Heavy Machine Manufacturing located?
The factory is at No. 10 Huanghai West Road, Hai'an City, in the Nantong area of Jiangsu Province, China.

What is the difference between a 3-roll and a 4-roll plate rolling machine?
A 4-roll machine clamps the plate between the top and bottom rolls, so it can pre-bend both ends and roll a cylinder in one pass. A 3-roll machine is simpler and lower in cost, but usually needs the plate to be repositioned to pre-bend the ends. Shengli builds both types.

Does Nantong Shengli supply complete LSAW pipe mill lines?
Yes. It supplies JCOE and CEO LSAW pipe mill lines for plate up to 50 mm thick and pipe lengths up to 12.5 metres, plus pipe bending machines.
