Our advantage when it comes to spiral welded pipe machines


The spiral welded pipe production line is a standardized finalization unit developed and improved by Dolco Heavy Industries, based on absorbing the essence of foreign forming technology and combining with the actual situation in China. It is the most competitive and mature unit with technical characteristics that are the most advanced of Dolco Heavy Industries.


Our strong points are:

•Production is 100% controlled and certified, with delivery of 2.2, 3.1 or 3.2 certificates according to EN10204 standard.


• Pipes can be produced with diameters up to 2850mm and wall thicknesses up to 25.4mm (30.0mm for steel grades up to S355).


 We can provide pipes in all requested steel grades due to our worldwide network of coil producers.


 Pipes can be produced up to 65 meters in length without circumferential weld. Longer tubes can be achieved by welding.
