  The  cylinder barrel tube   before processing the surface will have a lot of hemp point, which is an important factor affecting the quality of honing tubing, to get the quality of the hydraulic oil tubes after quilting, it is necessary to repair these points. So, what are the methods for repairing the surface defects of honing tubes? Increase the amount of cold-drawn deformation Increasing the number of  cold-drawn  deformation and increasing the total deformation can achieve the purpose of reducing the depth of the hemp point and reducing the honing grinding allowance. Preferred hot-rolled tube blanks Cold drawn tubes defects are caused by hot-rolled pipe, so, through the selection of small corrosion degree, uniform wall thickness of the hot-rolled pipe, can reduce the defects of the hemp, improve the yield of the cylinder. Hot-rolled pipe hole defect cleaning g is also relatively low, if the diameter is greater than 50mm, it is best to use mechanical process...

honed hydraulic tube  is referred to as a Honed tube. One of the most important materials of manufacturing hydraulic cylinders are Honed Tubes. This type of tubing is ordinarily honed in the inside diameter of a Ready to Honed Tube. Which is why it is also known as honed ID tubing. Honing is an abrasive or a grinding machining process that delivers a precision surface on a metal workpiece for e.g.   Hydraulic Tubes .  During this process, an abrasive grinding stone or grinding wheel is scrubbed against a Pre Honed Tube along a hegemonized path. Honing is a process which is fundamentally used to enhance the geometric form of a surface. ADVANTAGES OF OUR HONING 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 ...

As we all know,In the process of using the  hydraulic cylinder , the hydraulic cylinder barrel will be damaged,it is common that there will be scratch on the surface of the  honed tube , some customers will ignore these scratches, this to us is not responsible for the cylinder, when a small scratches in the cylinder,we usually take some tips to deal with them. 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  hydraulic cylinder barrel ...

hydraulic Honed tube  is a kind of tube that the inner hole of cold drawing tube is machined by honing head with the high speed grinding process, so that the inner hole achieves the tolerance dimension and surface roughness requirements required by us. It is widely used in  hydraulic cylinder  ,engineering machinery, metallurgical machinery, mining machinery, road construction machinery, textile machinery and other industries.

How to choose, process, and install  hydraulic cylinder tubes   properly, in order to make the hydraulic line system work more energy-efficient, reliable, and have a longer life? This has become an important issue for hydraulic technologies. As one of the leading China hydraulic tube manufacturer and supplier,  Datong Hydraulic  specializes in manufacturing hydraulic cylinder tubes and carbon steel honed tube for many years, and has many years experience of hydraulic tube related technology and research. This article will briefly describe the hydraulic pipe selection, processing, installation, etc., with hope to help the customers in the hydraulic system industry who are in need. CHOOSE THE RIGHT MATERIAL AND SIZE OF HYDRAULIC TUBES The hydraulic cylinder tubes should be selected according to the system pressure, flow and application environment. Must pay attention to the strength of the tubing whether is enough, whether the pipe diameter and the wall thick...

The required barrel is a key part of hydraulic cylinder , and sometimes the direct acting component of hydraulic cylinder (when piston rod or plunger is fixed); the barrel, end cover and piston (plunger) form a sealed chamber for containing pressure oil and driving the load for acting; thus the barrel has requirements for strength, rigidity and sealing as below: (1) The barrel should have sufficient strength to prevent permanent deformation under long-term rated operating pressure and short-term dynamic test pressure. (2) The barrel should have sufficient rigidity to prevent bending caused by lateral force imposed by the piston and reacting force during installation. (3) Reliable seal: The grade of dimensional tolerance and accuracy of geometric tolerance of cylinder inner surface, piston seal and supporting ring should be designed rationally to ensure reliable seal and reduce wear. (4) The cylinder barrel to be welded should have good weldability to avoid cracking or excess...
