API 5L and ASTM A53 Standards: These standards ensure that the steel pipe meets specific requirements for use in oil and gas industry applications, as well as for general use in mechanical and pressure applications.
Grade B: The designation "Grade B" indicates the strength and mechanical properties of the steel pipe, with specific requirements for yield strength, tensile strength, and impact properties.

| 0.26 | 1.2 | 0.03 | 0.03 | 241 | 414 |
SAW Welding: The pipe is manufactured using the Submerged Arc Welding (SAW) process, which involves the formation of a welded seam using a continuous submerged arc welding process. This method is known for producing high-quality, uniform welds.
Black Painted Finish: The black painted finish provides corrosion resistance and enhances the aesthetic appearance of the steel pipe. The paint also helps protect the pipe during storage and transportation.
Applications: API 5L ASTM A53 Grade B Black Painted SAW Welded Steel Pipe is commonly used in various applications, including oil and gas transmission pipelines, structural support in construction, and other industrial and mechanical applications.
