Small diameter seamless steel tube
| Item | Small diameter seamless steel tube/ pipe |
| Introduction | Small-caliber seamless steel pipe is a round, square and rectangular steel with a hollow section and no joints on the periphery. Seamless steel pipes are made of steel ingots or solid tube billets through perforation into capillary tubes, and then made by hot rolling, cold rolling or cold drawing. Seamless steel pipes have a hollow section and are mostly used as pipelines for conveying fluids. Compared with solid steel such as round steel, steel pipes have the same bending and torsion strength and lighter weight. They are economical cross-section steels with small outer diameters. Seam steel pipes can be called small-caliber seamless steel pipes. Small-caliber seamless steel pipes can also be divided into: seamless small-caliber steel pipes and straight seam (also known as welded) small-caliber seamless steel pipes, generally on the outer diameter of the steel pipe. Those below 89mm and those above 4mm can be collectively referred to as small-diameter seamless steel pipes. |

| Application | 1. Small-caliber seamless steel pipes are widely used in industrial plants, high-rise civil buildings, municipal engineering, oil platforms, bridges, railway vehicles and other fields. Because of their good plasticity, high structural stability, and strong resistance to natural disasters, they are especially suitable for earthquakes. Architectural structure in prone areas.
2. Small-diameter seamless steel pipes have high tensile strength and toughness. They have good cold bending performance and welding performance in steel structures such as high-rise buildings and bridges. The section size and surface quality are well controlled, so they are widely used in vehicle manufacturing. , Large-scale bridge construction, machinery manufacturing, industrial plant components and many other industries. 3. Small-caliber seamless steel pipes are mainly used to make transmission line towers, microwave transfer station towers, construction crane towers, elevator supports, etc. The idea is to choose weathering steel when the tower needs to meet the normal temperature and low temperature conditions. |
