1.First, to clean up the oil on the surface of our hydraulic cylinder barrel, then we will use the grinder machine to the surface treatment of the scratched part of our cylinder, at this time we have to grind the surface of the cylinder wall out of swallowtail groove.Although we have cleaned our cylinder at the beginning, at this time we need to clean the cylinder barrel further. At this time, we use anhydrous ethanol to clean the surface of the scratch repair of honed cylinder barrel.

2.We usually use special repairing adhesive to solve the scratches on the surface of cylinder barrel, before using it, we need to check the expiry date of the repairing adhesive to see whether the repairing adhesive or validity range, in addition, although some repairing adhesive within the period of validity, but due to improper storage has failure, it also can not work, After our hydraulic cylinder repair agent is pressed hard repeatedly, remember to make it higher than the surface of the original wall cylinder, and then make the repaired part warm and solidify.

ADVANTAGES OF DATONG’S HONED TUBE

1, High precision tolerances;
Our honed steel tube can meet ID tolerance H7, H8, H9, … etc according to the customer’ requirements, and its I.D dimension.

2, Seamless tube with high pressure resistance;
We only use seamless cold drawn tubes to produce honed pipes, which means our honed tubing can work under higher pressure, thus our honed pipes are more reliable for hydraulic cylinder applications.

3, High Smooth inside surface;
The roughness of our honed pipe is Max Ra 0.4 microns ID finish .

4, Good weldability: The weldability of our honed steel tubing is very good, this is quite helpful for manufacturing the cylinders.
