Not all steel pipes have weld seams. Steel pipes are categorized into seamless pipes, straight seam welded pipes (such as ERW), and spiral welded pipes. Seamless pipes, with no weld seams, are suitable for high-pressure or precision applications. ERW pipes are popular in construction, furniture, and automotive industries due to their high production efficiency and low cost. Aogang focuses on ERW pipe equipment, compliant with international standards.
