1200 model steel coil tube is made of steel-plastic composite profiled strip by the spiral wound (lap surface extrusion welding) welding, its high ring stiffness, the lining is smooth level off, the specification of DN200 - DN1200mm. This kind of tubing corrosion resistance, light quality, easy installation, large flow, and the advantages of long service life (50 years), alternative energy materials (cement, iron, ceramics, etc.) production of pipe material, environmental protection green products.

　　1200 model steel coil pipe production line adopts advanced modular design, equipment operation more simple. Adopt high efficiency single screw extruder, low energy consumption, high output. PLC intelligent control, stable and reliable, high degree of automation. Developed a unique model steel composite technology, strip and tube production at the same time, a molding, steel belt compound in HDPE completely, no bubble, no loss, corrosion from the other media. Configure the independent research and development
