Introduction:
Quilted seamless pipe is a kind of high precision steel pipe material after cold drawing or hot rolling. Because there is no oxide layer on the inner and outer walls of precision steel pipe, [1] under high pressure without leakage, high precision, high finish, cold bending without deformation, flaring, flattening without cracks and so on, it is mainly used for the production of pneumatic or hydraulic components, such as cylinders or cylinders, which can be seamless. The chemical composition of quilted seamless tube is carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, chromium Cr
Quilted seamless pipe adopts processing technology
The quilted seamless pipe is processed by rolling. Because of the residual compressive stress on the surface layer, it is helpful to close the micro cracks on the surface and prevent the expansion of erosion. It can improve the surface corrosion resistance and delay the generation or expansion of fatigue cracks, so as to improve the fatigue strength of quilted steel pipe. By rolling forming, a cold working hardening layer is formed on the rolling surface, which reduces the elastic and plastic deformation of the contact surface of the grinding pair, thus improving the wear resistance of the inner wall of the quilted steel pipe and avoiding the burn caused by grinding. After rolling, the reduction of surface roughness can improve the fit property.
Rolling machining is a kind of chip free machining. At normal temperature, the plastic deformation of metal is used to flatten the microscopic roughness of the workpiece surface so as to achieve the purpose of changing the surface structure, mechanical characteristics, shape and size. Therefore, this method can achieve the two purposes of polishing and strengthening at the same time, which is unable to do grinding.
No matter what kind of processing method is used to process, there will always be fine convex and concave uneven knife marks on the surface of the parts, and the phenomenon of staggered peaks and valleys,
Rolling processing principle: It is a kind of pressure finishing processing, is the use of metal in the normal temperature state of cold plastic characteristics, the use of rolling tools to exert a certain pressure on the workpiece surface, so that the workpiece surface metal plastic flow, fill into the original residual low concave trough, and achieve the workpiece surface roughness value reduced. Due to the plastic deformation of the rolled surface metal, the surface tissue cold hardening and grain thinning, the formation of dense fiber, and the formation of residual stress layer, hardness and strength, thus improving the wear resistance, corrosion resistance and compatibility of the workpiece surface. Rolling is a plastic machining method without cutting.
Quilted seamless pipe several advantages:
1, improve the surface roughness, roughness can basically reach Ra≤0.08µ m or so.
2, correct roundness, ellipticity can be less than 0.01mm.
3, improve the surface hardness, the force deformation is eliminated, hardness increase HV≥4°
4, after processing residual stress layer, improve the fatigue strength by 30%.
5, improve the quality of fit, reduce wear, prolong the service life of parts, but the processing cost of parts is reduced.

OEM/ODM China China Professional Supplier Hot Rolled Wide Flange Steel H Piles Steel Section H I Beam
I-beam is mainly divided into ordinary I-beam, light I-beam and wide flange I-beam. According to the height ratio of flange to web, it is divided into wide, medium and narrow flange I-beams. The specifications of the first two are 10-60, that is, the corresponding height is 10 cm-60 cm. At the same height, the light I-beam has narrow flange, thin web and light weight. Wide flange I-beam, also known as H-beam, is characterized by two parallel legs and no inclination on the inner side of the legs. It belongs to economic section steel and is rolled on four high universal mill, so it is also called “universal I-beam”. Ordinary I-beam and light I-beam have formed national standards.
