Heat treatment of  seamless steel tubes  is a process to improve the properties of metal materials and their products. Depending on the use, the material and its workpiece are heated to the appropriate temperature, insulated, and then cooled in different ways to alter the internal structure to achieve the desired performance. Heat treatment of seamless steel tubes is generally divided into annealing, normalizing, quenching, tempering, failure, chemical heat treatment and vacuum heat treatment. By heat treatment, the efficiency or life of the steel can be improved, and in some cases, more expensive special materials can be used instead of cheaper ordinary metal materials. The basic heat treatment methods of seamless steel tubes mainly include the following four forms: 1. Annealing Annealing is a process in which a seamless steel tube is heated to a slightly higher or lower critical temperature for a period of time (ie, heat preservation) and then slowly cooled. Common annealing...

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...

Hydraulic cylinder tube  is one typical application type of honed tube. It is made from  cold drawn seamless steel tube  (CDS tube), by the process of honing or Skiving & Roller Burnishing (SRB tube) on the inside surface. It is widely used to manufacture hydraulic cylinders, so it is known as hydraulic cylinder tube. As the most experienced hydraulic cylinder tube supplier and manufacturer, we can understand the requirements of our customers accurately, and we can give our suggestions to our customers to help them to choose the right materials and the hydraulic cylinder tube sizes. Here below are the main features of our hydraulic precision cylinder tubes. Tolerance  Our cylinder tubes with high accuracy tolerance can be provided by us at premium cost, mostly the tolerance of the honed tube  ID is ISO H8 ; and we also can manufacture hydraulic cylinder tubes with  ID tolerance H7 or H9  on customer’s request. Ovality  The ovality of cyli...
