ASTM A53 Class B LSAW Straight Seam Submerged Arc Welded Pipe
ASTM A53 Class B Welded Pipe Introduction
Type F - Furnace Butt Welding, Continuous Welding: This is a process where steel plates are preheated in a high-temperature furnace and then welded using welding materials. During welding, the steel plates are preheated to a sufficient temperature, and then welded in the furnace using welding materials to form a weld seam. Continuous welding refers to the continuous welding of steel plates in the furnace, allowing for the manufacture of longer pipes.
Type E - Resistance Welding: This is a welding process that heats and presses the edges of the steel plate together by applying current and pressure to both ends of the pipe, thus forming a weld seam. Resistance heating does not use molten welding materials; instead, it heats the edges of the steel plate to a sufficient temperature and then applies pressure to form a weld seam at the edge of the steel plate.
Tensile Requirements
| Grade | Tensile strength, min | Yield strength, min | Elongation in50 mm (2 in ) |

| psi | MPa | psi | MPa | note | |
| Grade B | 60,000 | 415 | 35,000 | 240 | Table X4.1 or Table X4.2 |
These mechanical properties make ASTM A53 Grade B steel pipe suitable not only for piping systems that transport water, gases, and other low-pressure fluids but also for supporting structures in architectural and mechanical constructions, such as bridges and towers.
