Structural Tubes, also known as hollow sections, are used as a structural element in buildings, bridges and other structures, and in a wide variety of manufactured products. It’s produced in round, square and rectangular shapes in a broad range of sizes and gauges. Rectangular Tubes are commonly used in welded steel frames where members experience loading in multiple directions.
Structural Tubes, also known as hollow sections, are used as a structural element in buildings, bridges and other structures, and in a wide variety of manufactured products. It’s produced in round, square and rectangular shapes in a broad range of sizes and gauges. Square Tube, similar to round tube, has efficient shape for multiple-axis loading as it has uniform geometry along two or more cross-sectional axes, and thus uniform strength characteristics. This makes it good choice for columns. It also has excellent resistance to torsion.

A series of studs are welded on the surface of the steel pipe by the studded tube automatic welding machine to strengthen the heat exchange components, which is characterized by: 1. The square circumference is welded equally; 2. The hexagonal circumference is welded equally. Compared with the traditional studded tube manufacturing process, the square and hexagonal studded tubes strengthen the heat exchange elements, which are formed by welding at one time. The phenomenon that the welding stud falls off after the welding is forced to stretch by tooling in the past has been changed, so that the studded tubes are welded more firmly and the welding stud is not easy to fall off. The welding studs, diameter, length, longitudinal spacing, number of circumferential welding stud and angle of inclination of welding stud are all factors affecting heat transfer of studded tubes. Therefore, it must be considered systematically to be more practical. The square and hexagonal circumferential welding and stud shaped tubes are used to arrange the welding and stud shaped tubes equally, which have a larger expansion surface, and the stud shaped tubes have a disturbing effect on the fluid, which can greatly improve the heat transfer coefficient, especially suitable for the enhanced heat transfer of high viscosity oil products, heavy oil and other medium.
Spiral wound finned tubes or crimped finned tubes spiral wound on the base tube, without welding, but spot welding at the end. Material of spiral wound finned tube or crimped finned tube: the finned strip can be copper, carbon steel, stainless steel, non-ferrous metal tube and fin, or it can be root welded or completely welded. Spiral crimped stainless steel finned tube. Spiral tension wound finned tubes for air coolers. Due to the high corrosion resistance of stainless steel, when the environment has certain corrosivity or cleanliness, such as climate industry, heating, drying and cooling, stainless steel crimped fin tubes can be widely used. Usually used for finned tube heat exchangers. The maximum working temperature is 180 â??. Compared with L-shaped finned tubes, spiral wound finned tubes or crimped finned tubes provide higher air side turbulence and heat transfer due to fins curling. Material standard of crimped fin tube: both base tube and fin can be carbon steel and stainless steel Carbon steel: A179, A192, SA210 Gr A1/C, A106 Gr B Stainless steel: TP304/TP304L, TP316/TP316L

Across several industries, a hydraulic cylinder tube is referred to as a Honed tube. One of the most important materials of manufacturing hydraulic cylinders are Honed Tubes. This type of tubing is ordinarily honed in the inside diameter of a Ready to Honed Tube. Which is why it is also known as honed ID tubing. Honing is an abrasive or a grinding machining process that delivers a precision surface on a metal workpiece for e.g. Hydraulic Tubes. During this process, an abrasive grinding stone or grinding wheel is scrubbed against a Pre Honed Tube along a hegemonized path. Honing is a process which is fundamentally used to enhance the geometric form of a surface.

SA 106-B DN300 SCH80X800 seamless steel tube Seamless precision steel pipes and welded pipes are basically the same in shape. They are mainly different in the forming process, which leads to different places and prices for them. For example, a water pipe is usually welded by bending the flat plate, and a weld can be found on it. The seamless precision steel pipe is generally formed by backlogging the molten steel in the molten state through the annular slit, and then forming it by stretching and other processing processes, so that there is no weld. In terms of performance, especially the pressure bearing capacity, it is greatly improved compared with ordinary steel pipes, so it is often used in high-pressure equipment. Such as pipeline connections for hydraulic equipment.
