Product Description Large Diameter of Spiral Welded Tube Mill Pipe Production Line Product DescriptionThe steel coils are unfolded and leveled by the mill equipment. And they are sent to the forming machine in a certain angle. Supplemented by a certain angle, the continual pipes are formed in the principle of three-roll rolling machine. Continual spiral welding is welded by submerged-arc welding machine. The uncoiling, coil detaching, leveling, steel cutting and welding are working on the fly-welding carriage. When the steel is welded, the fly welding carriage moves forward in the same speed with the host equipments. The host machine will not have the stop. After the steel welding finishing, fly welding carriage backs forward to the original position t owait another coil. This mode is called continuous production method with high efficiency, high pipe quality, rare welding repair and other advantages.According to the different function of our products, the back swing spiral welded pipe mills are divides in to API standard model and national standard model. API standard model mainly produces the delivery pipe with petroleum or natural gas (long distance).the material and quality of the steel pipe need to be very good. The requirements for mill equipment and testing equipment also are very high. National standard model produces the pipe used for short distance delivery of natural gas or water, the pipeline construction in the city, the structure pipe, column pipe and so on. The requirements for the material and quality of the steel also are very high, second only to that of API standard.Models:NoModelsOD(mm)Width(mm)Thickness(mm)Area(M2)1HNQLX-426Φ219 - Φ426300 - 6003 - 1424×2002HNQLX -529Φ219 - Φ529300 - 8003 - 1624×2003HNQLX -630Φ219 - Φ630300 - 10003 - 1824×2004HNQLX -720Φ219 - Φ720300 - 12004 - 25.424×2005HNQLX-820Φ219 - Φ820350 - 13003 - 1424×2006HNQLX -1020Φ273 - Φ1020350 - 13003 - 1624×2007HNQLX -1420Φ325 - Φ1420500 - 16003 - 1824×2008HNQLX -1620Φ426 - Φ1620500 - 16004 - 25.430×3009HNQLX -1820Φ508 - Φ1820500 - 20004 - 25.430×30010HNQLX -2020Φ508 - Φ2020500 - 20004 - 25.430×30011HNQLX -2400Φ508 - Φ2400500 - 20004 - 25.430×30012HNQLX -3000Φ610 - Φ3000500 - 20004 - 25.430×30013HNQLX -3500Φ720 - Φ3500600 - 20004 - 25.430×300Process:Loading Coil - Uncoiling-Leveling - Shear Butt Welding - Edge Milling - Feeding - Fly Welding - Delivering - Pre-Bending and Guiding - Forming - Internal Welding - External Welding - Tracking and Cutting Off - Pipe Delivering - Welding Seam Grinding - Pipe End Expanding - X-Ray Inspecting - Hydro Testing - Pipe End Charming - Ultrasonic Inspecting - Weighting, Measuring, Marking - Finished Products CollectingDetailed PhotosPackaging & Shipping1.
