20 # cylinder tube manufacturers offer

20 # cylinder tube manufacturers offer sales hotline: 13676382696 The company has a cylinder tube honing pipe unit 4, machine production 30--600 of honing tube (HM pipe cylinder tube). The company produces honing tube (HM pipe cylinder tube) roughness can basically meet Ra≤0.08μm about correcting roundness, ovality can ≤0.01mm, increase surface hardness, so that by eliminating deformation, hardness HV≥4 °, after processing residual stress layer, improve the fatigue strength increased by 30%, increasing with the quality and reduce wear and extend the life of parts. Cylinder honing steel tube HM pipe cylinder pipe pressure, pneumatic cylinder size and precision processing methods cylinder diameter mm Length m straightness mm / m diameter size difference in thickness precision bore roughness μ m cold drawn 40-320 ≤ 12M 0.2- 0.5 H8-H10 ± 5% 0.8-1.6 cold rolled 30-100 ≥ 12M 0.2-0.5 H8-H10 ± 5% 0.8-1.2 drawing - honing 40-500 8M 0.2-0.3 H7-H9 ± 5% 0.2-0.8 drawing - Rolling 40-400 7M 0.2-0.3 H8-H9 ± 5% 0.2-0.4 recently finishing mill 3, the outer diameter of 10-202 can be customized production, precision bright seamless steel pipe wall thickness of 1-18mm. Our factory produce cold rolled precision light control system looks smooth, uniform thickness, no oxide layer, high precision. Widely used in automobiles, motorcycles, power, petrochemical, shipbuilding, aerospace, bearings, pneumatic components, fuel tanks, boiler equipment, medical equipment, fitness equipment and other industries. GB can be customized non-standard precision tubes according to user needs. Material can be divided into 20 #, 35 #, 45 #, 40cr.16mn so on. Various national standard and customized non-standard precision tubes according to user needs. Precision Tube light pipe │ │ │ precision light pipe rolled precision light pipe can be customized to customer requirements in advance of non-standard and other special steel. Weekends and holidays, 24 hours a day you can do in the rail, road and sea transport, large concessions and shipped directly from the manufacturer. Today, good reputation for quality and service, there will be a wide breadth of market returns tomorrow, in each business from the beginning to the end of the whole process, regardless of how many customers need the goods, we will be available to every program to strict, honest pragmatic, fine, good service attitude to surplus cylinder tube is a long-time customer of high precision cold-drawn or hot-rolled steel material after processing a pass. Because precision steel inner and outer wall oxide layer, under high pressure without leakage, high-precision, high-quality finish, cold deformation, flaring, flattening without cracks a bit, so the main pneumatic or hydraulic components used in the production of products, such as cylinders or cylinder, which can be seamless. Chemical composition of the cylinder tube with carbon C, silicon Si, manganese Mn, S, phosphorus P, chromium Cr. Cylinder tube with processing cylinder tube using a rolling process, the surface layer of the surface residual compressive stress left, helps a closed surface microcracks, impede erosion expansion. Thereby enhancing the corrosion resistance of the surface, and can delay fatigue cracks or expanded, thus increasing the fatigue strength of the cylinder tube. By roll forming, cold rolling the surface layer of the hardened layer, the elastic and plastic deformation to reduce the grinding surface of the auxiliary contact, thereby improving the wear resistance of the inner wall of the cylinder tube, while avoiding burns caused by grinding. After rolling, the reduction of the surface roughness can be improved with the nature. Cylinder tube rolling process is a non-cutting machining, at room temperature using a metal plastic deformation, so that microscopic surface irregularities or rolling so as to achieve the purpose of changing the surface structure, mechanical properties, shape and size. Therefore, this method can simultaneously achieve finishing and strengthen both purposes, is not able to do the grinding.

Seamless steel tube and the difference between the fuel tank 1, the main characteristics of seamless steel pipe without welding seam, can withstand greater pressure. Products can be very rough cast or cold call. 2, the cylinder tube is a product emerged in recent years, mainly in the hole, the outer dimensions with tight tolerances and roughness. www.sdxzgg.com www.lcxzggc.com www.hmg6.com www.lcygg.com www.fsw-zy.cn www.hnlcgg.com www.hmggs.com www.hmgongju.com www.dwymg.com www.xzymg .com
