Learn about spiral welded pipe:
Helical welded pipe is made of low-carbon carbon structural steel or low-alloy structural steel strip rolled into a tube blank according to a certain helix angle (commonly known as forming angle). Once the tube is formed, the seams are welded together. Spiral welded pipe can be made from narrower strips to produce larger diameter steel pipes.
Advantages of spiral welded pipe:
1. Unparalleled Strength: Spiral welding technology ensures structural integrity and strength, making these pipes ideal for conveying high-pressure fluids and gases.
2. Versatility: These pipes can withstand extreme temperatures, making them suitable for a wide range of applications including oil and gas transportation, water supply, sewage treatment plants, and more.
3. Installation Efficiency: Since spiral welded pipes are capable of being manufactured in large diameters, the number of joints required is reduced, simplifying the installation process and minimizing potential leak points.
X65 SSAW Line Pipe: Provides Stability and Reliability:
Our X65 SSAW line pipe is specifically designed to meet the needs of the oil and gas industry. These pipelines excel at transporting crude oil, natural gas and refined products over long distances. With high tensile strength and excellent impact resistance, X65 SSAW line pipe exhibits excellent corrosion resistance, ensuring its durability even in harsh environments.

a. The deoxidation method is designated as follows: FF: Fully killed steel containing nitrogen binding elements in amounts sufficient to bind available nitrogen (e.g. min. 0,020 % total Al or 0,015 % soluble Al). b. The maximum value for nitrogen does not apply if the chemical composition shows a minimum total Al content of 0,020 % with a minimum Al/N ratio of 2:1, or if sufficient other N-binding elements are present. The N-binding elements shall be recorded in the Inspection Document. |
