Hydraulic tubes

 

Looking pipes for hydraulic cylinders?

These tubes have a better equidistance of generating linear axis of the inner wall of the tube and an error of straightness' internal lower 1 / 1000 compared to the originalraw tube.

During the drilling of the hot rough-hewn, the tube assumes a spiral shape that maintains, although in smaller amounts, after completion of hot rolling and drawing(fig. B).
The traditional processes such as grinding and rolling spiral and follow this trend,while obtaining the required tolerance, do not change the default spiral tube in contrast with the principle of concentricity of the ROD / PISTON / SLEEVE.
The demonstration of the extreme straightness of the finish system is HIGH in the photo (c). The processing of a small tube with internal machining allowance left blankspots appear (in the photo darker spots) where the working HIGH has not beeneffective because those areas are outside the maximum tolerated straightness.
To overcome this HIGH employs tubes with allowance higher than that required by the standard (up to 3mm in diameter) to ensure straightness, roundness and surface cleaning.
