Key Performance Advantages

The steel coils, welding wires, and fluxes put into production must undergo strict physical and chemical inspections to ensure the basic quality of the products.
The strip steel needs to undergo leveling, trimming, planing, surface cleaning, and pre bending treatment to lay the foundation for subsequent forming and welding.
Use an electric contact pressure gauge to ensure smooth steel strip transportation.
Apply external or internal control roll forming technology.
By using specialized devices to control the gap between welds, key indicators such as pipe diameter and misalignment are strictly met.
Both internal and external welding are carried out using American Lincoln welding machines for single or double wire submerged arc welding, ensuring efficient welding process and stable weld quality. Meanwhile, the active submerged arc welding technology further enhances the quality of the pipe body.
Using an air plasma cutting machine for fixed length cutting of steel pipes, with high efficiency and good quality.
Each batch of steel pipes must undergo strict inspection, including weld mechanical properties, chemical composition, fusion condition, surface quality, and non-destructive testing, to ensure that only products with fully qualified processes can be put into the market.

X-ray steel pipe inspection
The parts with continuous ultrasonic testing marks on the weld seam shall be manually inspected by ultrasonic and X-ray. If there are defects, they shall be repaired and subjected to non-destructive testing again until it is confirmed that the defects have been cleared.
The pipes where the strip steel butt welds and spiral welds intersect, as well as the T-shaped joints, are inspected by X-ray television or film.
