The special-shaped pipe is a general term for seamless steel pipes with cross-sectional shapes other than round pipes. As a manufacturer, it is also necessary for us to tell you about the main points of using special-shaped tubes. Interested partners can take a look together.

  Special-shaped pipeIt is a general term for seamless steel pipes having cross-sectional shapes other than round pipes. As a manufacturer, it is also necessary for us to tell you about the main points of using special-shaped tubes. Interested partners can take a look together.

Special-shaped pipe is a kind of economic section steel pipe. Including non-circular cross-section profiles, equal wall thickness, variable wall thickness, variable diameter and variable wall thickness along the length direction, symmetrical and asymmetrical cross-sections, etc. For example, some common front square, rectangle, cone, trapezoid. The special-shaped pipe can better adapt to the particularity of the use conditions, save metal, and improve the labor productivity of parts manufacturing. At present, the product is widely used in aviation, automobile, ship, mining machinery, agricultural machinery, construction, textile and boiler manufacturing and other fields. The production methods of special-shaped tubes include cold drawing, electric welding, extrusion, hot rolling, etc., in which the cold drawing method has been widely used. Now generally according to the section to distinguish, according to the material can be divided into seamless, aluminum alloy, plastic. The forming method of this product is solid bending square tube compaction, inner and outer wall re-bending, inner and outer roller compaction for two-way process. The advantage of the real bending of the rectangular tube is that the bending of the entity will be relatively small and will be more accurate, and as long as the roller type is used accurately during production, the internal rebound will be sufficient. The formed steel pipe is more accurate. We can guarantee the angle accuracy of the special-shaped steel pipe.

  Special-shaped pipeThere are many advantages. For example, plasticity refers to the ability of metal materials to produce plastic deformation without damage under load. Analysis of the hardness of the performance index of the special-shaped pipe. In fact, it is mainly a pointer to measure the degree of hardness of metal materials. At present, the commonly used hardness measurement method in production is indentation hardness method, which uses an indenter with a certain geometric shape to press into the surface of the tested metal material under a certain load, and determines its hardness value according to its hardness value. to the extent of indentation. Moreover, the strength, plasticity and hardness discussed above are all indicators of the mechanical properties of a metal under static load. In fact, many machine parts operate under cyclic loading, in which case the parts become fatigued. Of course, the special-shaped pipe also has impact toughness. The load acting on the machine at high speed is called impact load, and the ability of metal to resist damage under impact load is called impact toughness. In fact, its strength refers to the ability of a metal material to resist damage under static load. Due to the load, there are tensile, compression, bending, shear and other forms.

The content of the above article is to introduce the main points of the use of special-shaped tubes for all friends. Friends can read it carefully. Of course, there are still a lot of information about special-shaped pipes. We will continue to update later. The company is committed to the expansion and development of domestic and foreign markets, using online Internet e-commerce platform and offline physical sales in two ways.
