Steel Pipe

Steel pipes are hollow, long-strip metal products made primarily from carbon steel, alloy steel or stainless steel via processes such as hot rolling, cold drawing and welding. They are fundamental profiles widely used in industrial and construction fields. Classified by material and manufacturing technology, they include seamless steel pipes, welded steel pipes (ERW pipes, spiral welded pipes), alloy steel pipes, stainless steel pipes, etc., with a complete range of specifications and customizable sizes to meet diverse application needs.
Steel pipes stand out for their hollow structure, being lightweight yet high-strength with excellent bending and compression resistance. They also feature good corrosion resistance, heat resistance and processability, enabling various deep processing such as cutting, bending, welding and galvanizing to adapt to complex engineering scenarios. Seamless steel pipes have no welds on the surface, with uniform material composition and high pressure-bearing capacity, making them ideal for high-pressure, high-temperature and precision equipment. Welded steel pipes, on the other hand, offer high production efficiency and cost-effectiveness, widely used for general fluid transportation and structural support.
With their outstanding comprehensive performance, steel pipes are extensively applied in construction engineering (scaffolding, steel structure frames, guardrails), industrial manufacturing (mechanical parts, pipeline transportation), petroleum and chemical industry (oil and gas transmission, chemical pipelines), municipal engineering (water supply and drainage, gas pipelines), transportation and shipping (vehicle frames, ship structures), and aerospace. They are key materials supporting modern industry and infrastructure construction.
