Seamless Steel Pipe

Description

Seamless steel pipe is a long, hollow cylindrical steel product without any welded seams, offering superior strength, durability, and resistance to pressure. Manufactured through hot rolling or cold drawing processes, it ensures uniform structure and excellent mechanical properties. Seamless pipes are widely used in high-pressure applications such as oil and gas transportation, power generation, chemical processing, and boiler systems. They offer better corrosion resistance, precise dimensional accuracy, and higher load-bearing capacity compared to welded pipes. Seamless steel pipes are also ideal for structural and mechanical applications where safety and reliability are critical. Their smooth inner surface enhances flow efficiency and reduces maintenance needs.

Application scope
Round steel has broad application prospects and is widely used in hardware, construction, automotive, shipbuilding,
petrochemicals, machinery, medicine, food, electricity, energy, aerospace, and building decoration. The most extensive processing of ordinary mechanical parts, including general rod steel parts, CD rods, bolts, and nuts.
Material grade
10 #, 20 #, 35 #, 45 #, Q215, Q235, 304, 316, 20Cr, 40Cr, 20CrM o, 35CrMo, 42CrMo, 40CrNiMo, GCr15, 65Mn, 50Mn, 50Cr, 3Cr2W8 V,20CrMnTi, 5CrMnMo
The difference between round steel and other steel bars:
1. The appearance is different. Round steel has a smooth and round shape, without lines or ribs, while other steel bars have grooves or ribs on their surface. This results in a low bonding force between round steel and concrete, while other steel bars have a high bonding force with concrete.
2. The composition is different. Round steel (first grade steel) belongs to ordinary low-carbon steel, while other steel bars are mostly alloy steel.
3. The strength is different. Round steel has lower strength, while other steel has higher strength. That is, compared to other steel bars with the same diameter, round steel can withstand less tensile force, but its plasticity is stronger. That is, round steel has greater deformation before being pulled apart, while other steel bars have much smaller deformation before being pulled apart.
