 When it comes to hydraulic cylinders, the quality of the cyinder barrel directly impacts performance, durability, and efficiency. ​ E355 seamless tubes ​ stand out as a premium solution, offering superior strength, precision, and reliability compared to welded or inferior-grade alternatives. Why Choose a E355 Seamless Tubes?​ ​ ​1. Superior Strength & Durability​ ​Seamless Construction:​​ Unlike welded tubes, seamless E355 tubes have ​no weak points, ensuring uniform strength and resistance to high-pressure conditions. ​High-Quality Material:​​ E355 steel (EN 10297-1) provides excellent ​mechanical properties, including high tensile strength and impact resistance. ​Longer Lifespan:​​ The absence of welds reduces the risk of cracks, leaks, and premature failure, making it ideal for ​heavy-duty hydraulic systems. ​2. Precision Honing for Optimal Performance​ ​Smooth Inner Surface:​​ Honing achieves a ​fine surface finish (Ra 0.2–0.4 µm)​, reducing friction and wear on seals a...

  ST52 Cylinder Barrel  is well known as hydraulic cylinder tube in industries.  Honed Tubes , Skived & Roller Burnished Tubes are the most important material of manufacturing  hydraulic cylinders . Delivery Condition Of ST52 Cylinder Barrel Normal speaking , Annealing and normalizing of steel are two common heat treatment processes.The purpose of annealing and normalizing is to eliminate certain defects caused by hot processing of steel, or to prepare for the subsequent cutting and final heat treatment. As a professional cylinder barrel factory,  Datong Hydraulic  can do production with Delivery Condition: BK, BK+S, GBK, NBK. To keep the cylinder tube good working performance. Cold Finished(BK):  Honed Cylinder Tubes  do not undergo heat treatment following the final cold forming and thus, have a rather high resistance to deformation. Cold finished and stress-relieved (BK+S): Heat treatment is applied following the last cold forming 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 ...

  HYDRAULIC HONED PRECISION TUBES Hydraulic honed tubes  are seamless, hot rolled and honed. They can be used for manufacturing any hydraulic cylinder. Honing is finishing method whose goal is to ensure perfect surface grade, in our case final treatment of the inner diameter of the tube. Advantage of this classic procedure is high geometrical accuracy of the shape with minimal conicity and waviness of the surface. However, after the process, they will be a large number of spiral grooves from the grinding tool. These result in greater wear and lesser lifespan of the seals, compared to the roller burnished tubes. Final surface will have roughness Ra 0,4 μm. Hydraulic Honed Tubes are made of ST52.0 (E355) material. ST52 Hydraulic Cylinder Tubes are preferred in various sizes and thickness by our clients all across the globe. SKIVED AND ROLLER BURNISHED PRECISION TUBES These tubes are cold drawn, skived and roller burnished. They can be used for manufacturing any hydraulic cylinde...

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 ...

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...
