The spiral welded pipe unit produced by our company adopts the double swing bridge process. The front axle mainly includes uncoiler, scraper, three roll, five roll car leveling device, splicing machine, milling machine, delivery machine, forming machine, etc. The rear axle mainly includes gantry frame, landing gear and other components. The reasonable swing of the front and rear axles saves a lot of space.
After years of practice, it has been proven that this unit has many advantages such as stable molding, high degree of automation, low energy consumption, and high production efficiency.
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
Fully automatic steel pipe hydrostatic testing machine
The hydraulic testing machine is mainly used for pressure testing of welded pipes, and has the functions of computer recording, storage, printing, and test results. It has the advantages of high efficiency, high testing pressure, and strong safety. The pipe diameter range is from Φ 20 to Φ 3500mm, and the test pressure is 10-110MPa.
Process flow: upper pipe - connecting pipe - water filling - pressure pressing - pressure holding - pressure relief - drainage - outlet pipe.
Fully automatic flat head chamfering machine
The flat head chamfering machine is mainly used for flattening and chamfering the ends of welded pipes. Equipped with a contour chamfering knife, the processed groove is uniform and beautiful. Our company provides flat head chamfering machine processing range for steel pipe production enterprises, covering steel pipe diameters ranging from 20mm to 3500mm, while meeting standards such as API-5L, API-5CT, BS1387-85, ASTM, GB9711, etc.
Process flow: upper pipe - connecting pipe - clamping - flat head chamfering - releasing fixture - outlet pipe
Ultrasonic flaw detector:
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;
X-ray steel pipe inspection:
The detection system seamlessly integrates with the entire production line, adapting to the control and management process requirements of steel pipe manufacturers. Welding seam automatic recognition technology facilitates automatic control during the preparation stage of inspection; Equipped with a database, the detection parameters of the same product can be automatically loaded with just one click; The entire system has a high degree of automation and operation detection, with a very high market share in domestic steel pipe production lines.
