 Hydraulic tube, is one of seamless steel pipe material, the carbon content between 0.24-0.32%, simn separate because because of the five elements (carbon C, silicon Si, manganese Mn, phosphorus P, sulfur S), the high levels of manganese is about 1.10-1.40%. 
 Hydraulic stent, the implementation of standards GB/T17396-1998. Mainly for the production of coal and hydraulic support cylinders, columns, and other hydraulic cylinders, columns. 
 Stent made of representatives of the hydraulic hydraulic support pipe 20, 45 hydraulic support pipe, 27SiMn hydraulic support pipe. 
 Hydraulic prop tube, the implementation of standards GB/T17396-2009. Mainly for the production of coal and hydraulic support cylinders, columns, and other hydraulic cylinders, columns. 
 Hydraulic prop tube made of representatives of 20 hydraulic prop tube, 45 hydraulic prop tube, 27SiMn hydraulic prop tube. 
 Hydraulic tube hydraulic pipe hydraulic prop stent advantages: 
 With mechanical drive, electric drive compared to the hydraulic drive has the following advantages: 
 1, a variety of hydraulic components, as needed easily and flexibly to the layout. 
 2, light weight, small size, inertia is small, fast response. 
 3, manipulation and convenient control, enabling a wide range of variable speed (up to 2000:1 speed range). 
 4, automatic overload protection. 
 5, generally use mineral oil as a working medium, the relative motion plane can be self-lubricating, long life; 
 6, it is easy to achieve linear motion / 
 7, it is easy to achieve automation of the machine, when the joint use of electro-hydraulic control, not only can achieve a higher degree of automatic control process, and can achieve remote control.
