Customized High Frequency Straight Seam Welded Pipe Unit Oil And Gas Pipelines Widely Applicable
Due to its reliability and progressiveness, Duolek longitudinal welded pipe unit has become an ideal choice for many industrial fields.
High frequency straight seam welded pipe unit:
This unit combines advanced technology, reliable equipment, and complete processes, making it particularly suitable for situations that require high efficiency, continuous production, and high surface quality requirements. Its molding is stable, the specifications are easy to change, and it can quickly respond to diverse production needs. It performs well in fields such as civil construction, furniture, and lightweight structures.
Fully automatic steel pipe hydrostatic testing machine
The DORCO fully automatic steel pipe hydrostatic testing machine is the main inspection equipment for welded pipe production. It adopts PLC control, and each part of the work process is automatically completed in sequence, with the function of automatic recording of test result parameters. The pipe diameter range is from Φ 20 to Φ 3500mm, and the test pressure is 10-110MPa.
Fully automatic flat head chamfering machine
Steel pipe diameter: 20mm -3500mm, among which the flat head chamfering machine with a diameter range of 60mm -339.7mm is a step feeding high-speed flat head chamfering machine, suitable for petroleum casing and ERW welded pipe production enterprises.
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
The Duolek Heavy Industry X-ray equipment can not only detect hidden welding points of various welded pipes, but also intelligently analyze the detection results, providing an effective detection method for achieving the goals of "first pass rate" and "zero defects".
Application scope:
This production line is a specialized equipment for producing straight seam welded pipes in industries such as metallurgy, petroleum, construction, transportation, machinery, and vehicles.
