Our fully automatic ultrasonic testing equipment is designed specifically for quality inspection of spiral welded pipes.Take the initiative to alarm and spray marks if there are shortcomings, and workers adjust parameters accordingly;The parts with continuous ultrasonic testing marks on the weld seam shall undergo manual ultrasonic and X-ray re inspection again;Defects will be repaired and undergo non-destructive testing again until they are confirmed to be cleared;The application of ultrasonic automatic flaw detection equipment will greatly improve the quality control efficiency and reliability of spiral welded pipe production lines, providing strong technical support for ensuring product safety in key areas such as oil and gas transportation and structural engineering.If you would like to learn more technical details or obtain customized solutions, please feel free to contact us at any time.

The spiral welded pipe production line is a standardized finalization unit developed and improved by Duolek 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  Duolek Heavy Industries.  Our strong points are: Adopting double swing bridge technology, the swing is reasonable, saving space and improving production efficiency Conduct strict physical and chemical inspections on raw materials to ensure product quality Adopting advanced welding processes and equipment to ensure stable welding quality Adopting non-destructive testing techniques such as ultrasound and X-ray to ensure the quality of welds After a strict inspection system, it is ensured that the pipe production process is qualified before production can begin The unit accessories are sourced from internationally renowned brands such as Lincoln welding machines from the United States and Siemens motors, ensuring the stability and reliability of the equipment  The Duolek spiral welded pipe production line can meet the needs of different industries and provide customers with high-quality products and solutions.

The numerical control system has many highlights:Use electronic handwheel for operation.It can achieve multifunctional and multi station rolling.Input the dimensions of the ring and blank, and automatically generate the rolling curve.Easy to operate, only one electronic handwheel is needed to complete the entire rolling process.The dual screen displays the working status, and the new console has a wide field of view.Automatic CAR operation mode, the rolling process automatically matches the radial and axial rolling according to the rolling curve.

The automation configuration is as follows:1. Use a slide table with a single axis robot to grab the bars from the heating furnace and send them to the upsetting station of the press;2. Use a flat four axis robot to transfer workpieces at three workstations of the press;3. Single axis robots equipped with ejector devices and transition tables are used to unload and wait for materials at the three workstations of the press;4. Adopting a dual robot mobile platform for automatic loading and unloading of the ring rolling machine;5. Use KUKA210 robot for loading, unloading, and palletizing of ring components;6. Automation auxiliary equipment: waste conveying installation;7. Mold cooling and cleaning device;8. Raw material cooling conveyor line;9. Stacking pallets, etc.The system includes functions such as on-site monitoring, real-time production indicators, and equipment efficiency analysis. Through a visual dashboard, the on-site status can be easily and clearly understood.
