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.
