Differences Between Seamless Steel Pipes and Welded Steel Pipes
The main differences between seamless steel pipes and welded steel pipes lie in their manufacturing processes and performance characteristics:
Manufacturing Process: Seamless steel pipes are made through hot or cold rolling processes, while welded steel pipes are made by rolling steel plates or strips and then welding them.
Performance Characteristics: Seamless steel pipes have higher strength and better sealing performance, while welded steel pipes have the advantages of cost-effectiveness and high production efficiency.
Application Fields: Seamless steel pipes are more suitable for high-pressure and high-temperature industrial environments, while welded steel pipes are more suitable for construction and infrastructure construction.
