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.
