The reasons for pinholes in the weld seams of spiral submerged arc welded steel pipes
During the production process of spiral steel pipe welding, issues such as incomplete welds and misaligned edges are common. However, the most difficult issue to control is the appearance of pinholes at the butt welds of spiral steel pipes.
How to Select Anti-corrosion Coatings for Steel Pipes in Industrial Projects
There are various types of anti-corrosion coatings, and different types of anti-corrosion steel pipes also have differences in performance and application. Correct selection of the coating is crucial for the anti-corrosion effect and the lifespan of the coating.
The wide application of seamless stainless steel pipes
Seamless stainless steel pipes, as the name suggests, refer to stainless steel pipes manufactured using a seamless process. Compared to welded pipes, seamless steel pipes have significant advantages in strength and corrosion resistance.
How much do you know about DN2008 seamless steel pipes?
DN2008 seamless steel pipe is an extremely important type of pipe material, playing a crucial role in both industrial and construction fields.Understanding its manufacturing process and applications helps us better understand the characteristics and advantages of this type of steel pipe.
What are the characteristics of large diameter industrial steel pipes?
Strength of Large-Diameter Steel Pipes: Strength refers to the property of a metallic material to resist failure (excessive plastic deformation or fracture) under static load. Since loads can be applied in the form of tension, compression, bending, and shear, strength is also divided into tensile strength, compressive strength, bending strength
Anti-corrosion Treatment Methods for the Inner Walls of Large-Diameter Spiral Steel Pipes
Cement mortar coating should generally be applied after the spiral steel pipe has been laid, pressure tested, and backfilled and compacted according to design requirements. This is because spiral steel pipes have low rigidity and thin walls, and the pipeline must be in a stable state during coating application. If the coating is applied before the
