Seamless Steel Tube has excellent corrosion resistance and its versatility allows for a wide range of applications. Due to the special process used in the manufacturing of Seamless Steel Tube, it is well suited for high-pressure and high-stress scenarios.
Seamless Steel Tube differs from welded steel tubes in that it does not have any welded joints and is a hollow cylindrical structure made from a single piece of steel. This seamless structure provides better uniformity, greater durability, higher strength and compression resistance, and superior performance in extreme environments, making it the preferred choice in industries where reliability is critical.
Selection of suitable raw material: High quality billets are selected as the raw material according to the application area and the expected properties of the final product (e.g. strength, corrosion resistance and flexibility).
Heating: The billet is heated to a very high temperature (usually around 1200°C), which facilitates the subsequent forming process.
Punching: The heated billet is very flexible and a piercing machine is used to punch holes in the billet to transform it into a hollow tube.
Rolling and stretching: The blank is rolled and stretched by means of a mandrel mill or an extension machine to achieve the required diameter and wall thickness.
Cooling and Straightening: The tubes are cooled to room temperature and then straightened top and bottom and side to side to ensure dimensional and straightness accuracy.
Cutting and Inspection: The tubes are cut to the required lengths and subjected to rigorous quality testing, including ultrasonic testing, to ensure that they meet industry standards.
Corrosion resistant and high strength, Seamless Steel Tube is suitable for use in highly corrosive and high-pressure environments such as chemical plants and offshore oil platforms.The high dimensional accuracy of Seamless Steel Tube ensures that it is manufactured in full compliance with industry standards. It is lighter than welded tubes, which helps to reduce costs in transport and installation.
Oil and gas industry: used for drill pipes, pipelines and oil well casing.
Energy industry: Commonly used in boilers, turbines and power plant systems.
Machinery and equipment: for hydraulic systems, bearings and heat exchangers.
Automotive industry: for components such as drive shafts, exhaust systems and hydraulic cylinders.
Construction industry: for structural supports, scaffolding and bridge construction.
