Aogang provide customized solutions for the production of various types of pipes, with a wide range of applications in the industry, covering the processing needs of various shapes and materials such as round pipes, square pipes, rectangular pipes, oval pipes and special-shaped pipes.

Q:

Do all steel pipes have weld seams?
A:

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.

Q:

What are the applications of a tube mill line?
A:

Tube mill lines are widely used for manufacturing structural pipes for construction, mechanical pipes, automotive tubing, oil and gas pipelines, water pipes, electrical conduit, and more. Based on welding technology, they are mainly classified into High-Frequency Electric Resistance Welding (ERW/HF), Tungsten Inert Gas Welding (TIG), and Submerged Arc Welding (SAW). Aogang specializes in ERW tube mill lines, offering high-efficiency and stable pipe production solutions.
