Key Performance Advantages
- All raw materials including steel coils, welding wires, and fluxes undergo strict physical and chemical inspections to ensure product quality from the source.
- Pre-forming processes include leveling, trimming, planing, surface cleaning, and pre-bending treatment to ensure plate quality and high-precision forming.
- Electric contact pressure gauge controls conveyor pressure for smooth strip steel transportation.
- Advanced external or internal control roll forming technology.
- Weld seam gap control device ensures pipe diameter, alignment, and gap meet welding standards.
- Internal and external welding performed with American Lincoln electric welding machines using single/double wire submerged arc welding for stable, reliable quality.
- Air plasma cutting machine provides accurate, smooth cuts on steel pipes.
- Comprehensive final inspection system includes weld mechanical properties, chemical composition, fusion condition, surface quality, and non-destructive testing.
X-ray Steel Pipe Inspection
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.
