Product Description Pre-Finish Welding Spiral Pipe Mill Tube Mill Product DescriptionPre finish welding spiral welded pipe mill is to let the forming and welding separate to the two processes. The forming machine adopts high-speed forming. Compared with the normal spiral welded pipe mill, the forming of pre-welding & precise welding spiral welded pipe mill does not weld completely. It only uses the CO2 protective welding to have the pre-welding on the steel joint part. It will be ok only let the steel joint part to be not open. Then, the pipe will be sized and cut off. After the pipe is sent out the line, the pipe will be delivered to the precise welding machine to have the detailed welding on the internal & external welding seam.This kind of forming technology has many advantages. Firstly, the forming and welding are separated. Then, the effect from forming process will be eliminated during the precise forming. The welding seam quality can be guaranteed more. Secondly, the production efficiency is the four times of the one in normal spiral line due to adopting the high-speed forming machine (the speed can reach to 8m/min). The precise welding machine has four sets. Then, the one combined mill production capacity can be three or four times of the normal one. This kind of mill is suitable for large pipe plant with good quality and high efficiency. This mill is mainly used for manufacturing the oil, gas (long distance) delivery pipe, which has the high requirement on the material and quality, the same as the equipment and testing equipment.Models:No.ModelOD (mm)Coil Width (mm)Thickness (mm) Area (M2)1HNYLX -1420Φ630~Φ1420600~20004~25.430×6002HNYLX -1620Φ630~Φ1620600~20004~25.430×6003HNYLX -1820Φ630~Φ1820600~20004~25.430×6004HNYLX -2020Φ720~Φ2020600~20004~25.430×6005HNYLX -2400Φ720~Φ2400600~20004~25.430×6006HNYLX -3000Φ720~Φ3000600~20004~25.430×6007HNYLX -3500Φ720~Φ3500600~20004~25.430×600 Process:Loading Coil→Uncoiling→Leveling→Cutting And Coil Welding →Edge Milling Machine→Feeding Machine→ Pre-bending And Guide Board→Forming → Pre-Welding→Cutting Off→Pipe Delivery Out→Deliver The Pipe To The Precise Welding Machine(4 Lines Working Together)→Pipe Loading→Finding The Welding Position→Pipe Rotating And Internal & External Welding At The Same Time(Welding Seam Tracking)→Pipe Exit→Welding Seam Grinding→X-Ray Inspection→Pipe End Expander→Hydro Tester→UT Continuous Detection(Pipe Welding Seam And Steel)→Pipe End Facing And Beveling →Pipe End Take Photo→Weighting, Measuring , Marking→ Finished Product CollectionDetailed PhotosPackaging & Shipping1.
