Difference between Seamless Steel Pipe and ERW Pipe
Steel pipes are designed in seamless and welded configuration types. Both the components can be distinguished on certain key characteristics.
Manufacturing process of Seamless Steel Pipe
Seamless pipes are designed without a weld joint or a seam and showcase a uniform structure across its length. A seamless grade Steel Tube can be processed by passing hot steel billets through an extrusion process. The billet stretches a hole through the center of the tube, and a billet shaped point piercer pushes through the grade. These billets are shaped precisely in piercing mills and increase the mold length by 20 times to shape the seamless steel pipe. Larger diameter pipes are processed in a mandrel mill processing system. The mandrel bars create a more standardized outside diameter, having controlled wall thickness. These pipes can be later stress relieved, normalized, and tempered to meet the requirements across different harsh environmental conditions.

What is Hot Finished Welded Tubes?
Hot finishing of welded tubes is a process wherein metal grade is processed at extreme temperatures at 1700 F or above in mills. The Hot Finished Welded Tubes reach their recrystallization limit at this juncture. The tubes are subsequently allowed to cool in a controlled setting. The process helps reduce internal stresses and mechanical inconsistencies in the heat affected zone. This allows the welding process to take place quite easily as the tubes showcase enhanced ductility and can be readily manipulated. The tubes are thereby; prone to cracking, allowing for better fabrication and installation properties. The versatile grade of Steel Pipes and Tubes are designed to function at high pressures and elevated temperatures. Furthermore, the grade is a viable cost-effective alternative to seamless tubes that require special equipment to be precisely formed. Also unlike, seamless pipes these modules can be supplied in custom sizes and dimensions reducing, any installation challenges and problems.
