Jiangxi thick-walled cylinder tube produced varieties specifications: Diameter diameter 30mm-300mm, wall thickness 2mm-40mm. Technical conditions: H5-H10 precision bore bore roughness Ra≤0.63um, straightness ≤0.3mm / m. Steel is 20 # -45 #, 16Mn, 27SiMn and some low-alloy steel standard GB8713-88. Honing production of major equipment: 350 tons of prestressed high-precision hydraulic drawing machine and 150 tons each in Taiwan, pulling machine maximum travel 12 meters, the maximum drawing force of 350 tons. And there are two sets of vertical honing machines, horizontal honing machine 2. Main purpose: hydraulic, pneumatic cylinder; hydraulic lines; spinning, textile and printing machinery pipe; automobile shock absorber tube; sleeve tube; rod and precision steel pipe. According to customer requirements are also available: Length of pipe, tube and special honing heat pipe. Jiangxi thick-walled cylinder pipe company to provide the following services: * Zero run, one from the sale. * Customers can pick and choose the desired length or other requirements. * Booking, purchasing all kinds of steel products or special specifications spot. * Swap temporary lack of specification of the library, eliminating the need for you to run around the procurement of hard work. * Arrange transportation, large straight hair you can specify the location. Now I have a lot honing tube, hydraulic cylinder tube, HM tube, cylinder tube, rod tube, bearing steel, high-precision drawing stock, will be preferential prices, wholesale and retail ways, to provide you with fast quality service, welcome new and old customers to negotiate, Power Conference smaller walled cylinder tube outer diameter Features 1.. 2. Do small batches of high precision cold drawn finished raw high accuracy, good surface quality. 4 Steel Cross area more complex. 5. Pipe better performance, relatively dense thick metal cylinder tube material used 10 # 0.07 ~ 0.13 0.17 ~ 0.37 0.35 ~ 0.65 ≤0.035 ≤0.035 20 # 0.17 ~ 0.23 0.17 ~ 0.37 0.35 ~ 0.65 ≤0.035 ≤0.035 35 # 0.32 ~ 0.39 0.17 ~ 0.37 0.35 ~ 0.65 ≤0.035 ≤0.035 45 # 0.42 ~ 0.50 0.17 ~ 0.37 0.50 ~ 0.80 ≤0.035 ≤0.035 40cr 0.37 ~ 0.44 0.17 ~ 0.37 0.50 ~ 0.80 ≤0.035 ≤0.035 0.08 ~ 1.10 25Mn 0.22 ~ 0.2 0.17 ~ 0.37 0.70 ~ 1.00 ≤0.035 ≤0.035 ≤0.25 fix thick walled cylinder tube cylinder tube surface defects prior to processing the surface will be a lot of pitting, which is an important factor affecting the quality of the thick-walled cylinder tube, in order to pass honing After obtaining good quality hydraulic pipes, we need to fix these pits. So, fix hydraulic pipe surface defects, what does? 1. Increase the amount of deformation increases cold drawn cold drawing deformation passes, increase the total amount of deformation may lead to lower pitting depth, reducing the honing grinding allowance purposes. 2. Preferred hot-rolled tube blanks drawn tube pitting defects are caused by hot-rolled tubes, so the extent of corrosion by selecting a small, uniform thickness of hot-rolled tubes can reduce pitting defects and improve the cylinder timber rate. 3. Hot-rolled tube defects in the hole to clean. Product quality is a prerequisite, and only good quality, and customer service is fundamental, therefore, hydraulic tube defects surface perfect repair, is our biggest commitment to customers
