All raw materials such as welding wire, flux, and strip steel must
undergo strict physical and chemical inspections before being put
into use to eliminate quality hazards at the source.
The strip steel undergoes a complete set of processes including
leveling, trimming, planing, cleaning, and pre bending, providing
perfect conditions for rolling and forming.
Smooth conveying: The electric contact pressure gauge accurately
controls the conveying pressure to ensure the smooth operation of
the strip steel.
Adopting external or internal control roll forming technology.
The weld seam gap device ensures strict control over pipe diameter,
misalignment, and weld seam gap.
The core internal and external welding processes are completed by
Lincoln welding machines from the United States (single/double wire
submerged arc welding), combined with active submerged arc repair
welding, resulting in stable and excellent welding quality.
Using an air plasma cutting machine, cutting is fast and precise.
Perform comprehensive inspections covering mechanical properties,
chemical composition, fusion condition, surface quality, and
non-destructive testing. Only fully qualified steel pipes can be
delivered to customers.
Continuous ultrasonic testing marks on weld seams undergo manual ultrasonic and X-ray inspection. Any defects are repaired and retested until cleared.
Strip steel butt welds, spiral weld intersections, and T-joints are inspected by X-ray television or film.
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.
