Product Description
First, how is the cross section of cold-drawn seamless steel pipe
1. Cold-drawn seamless steel pipe is a long steel strip with hollow section and no joints around it.The steel pipe has a hollow section and is widely used for conveying fluids, such as conveying oil, natural gas, gas, water and some solid materials. Steel pipe and round steel and other solid just compared with the bending and torsion strength at the same time, lighter weight, is an economic section of steel, widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipe, car drive shaft, bicycle frame and construction of steel scaffolding.
2. Making ring parts with steel pipe can improve material utilization rate, simplify manufacturing process, save material and processing time, such as rolling bearing ring, jack sleeve, etc., has been widely used to manufacture steel pipe. Steel pipe or all kinds of conventional weapons indispensable material, gun barrel, barrel and so on to make steel pipe.
3. Steel tubes can be divided into cold-drawn seamless steel tubes and special-shaped tubes according to the shape of the cross-sectional area. Since the circle has the largest area with the same perimeter, more fluid can be transported with a circular tube. In addition, when the annular section is subjected to internal or external radial pressure, the force is more uniform, so the vast majority of steel tubes are cold-drawn seamless steel tubes.
Second, the bending pressure resistance technology of cold-drawn seamless steel pipe is introduced
1. Square pipe Association continues to pay attention to and report that cold-drawn seamless steel pipe also has certain limitations. For example, under the condition of plane bending, cold-drawn seamless steel pipe is not as strong as square and rectangular pipe in bending strength. According to different uses also need to have other cross-section shape of the steel pipe, the structure of cold-drawn seamless steel pipe is used for general structure and mechanical structure of cold-drawn seamless steel pipe.
2. Cold drawn seamless steel pipe for fluid transportation is used for conveying water, oil, gas and other fluids. Cold-drawn seamless steel tubes for low and medium pressure boilers are high quality carbon structural steel hot-rolled and cold-drawn seamless steel tubes, which are used for manufacturing superheated steam pipes, boiling water pipes for various structures of low and medium pressure boilers and superheated steam pipes, large smoke pipes, small smoke pipes and arch brick pipes for locomotive boilers.
3. Cold-drawn seamless steel tubes for high pressure boilers are high quality carbon steel, alloy steel and stainless heat-resistant steel cold-drawn seamless steel tubes used for manufacturing the heating surface of water tube boilers with high pressure and above pressure. The reasons influencing cracking of cold-drawn seamless steel pipe are work hardening. Hydrogen embrittlement.
The effect of work hardening on steel pipe during cold drawing produces a large number of plastic deformation, resulting in obvious lattice distortion, which increases lattice energy and metal internal energy, resulting in uneven internal stress of metal and residual internal stress. This makes the metal harder and less ductile.
