How to choose, process, and install hydraulic 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, our company Younglee Metal specializes in manufacturing stainless steel hydraulic tubing and carbon steel hydraulic tubing for many years, and has many years experience of hydraulic tube related technology and research, we solved the hydraulic tube related technical issues for many customers, and provided production and technical services to them.
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 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 thickness meet the system requirements, and the inner wall of the selected steel pipe must be smooth, non-corrosive, non-oxidized skin, no clips and other defects. If any of the following problems is found on the hydraulic tube, it cannot be used:
- the inner and outer walls of the hydraulic pipe have been heavily rusted;
- the scratch depth of the pipe body is more than 10% of the wall thickness;
- the surface of the pipe body is recessed to more than 20% of the pipe diameter;
- the wall thickness of the pipe section is uneven and the ellipticity is obvious.
In applications of medium and high pressure hydraulic systems, the seamless steel tubes are generally used, because they have the advantages as high strength, low price, and easy leak-free connection, it is widely used in hydraulic systems.
Ordinary hydraulic systems often use cold drawn low carbon steel tubes, because carbon steel hydraulic tubing can be reliably welded to various standard pipe fittings. And for applications where there is corrosion resistance is required, such as Hydraulic servo system, often use ordinary stainless steel seamless pipe, stainless hydraulic tubes are with corrosion resistance, smooth inner and outer surfaces, accurate size.
Regarding how to choose the right outside diameter and the wall thickness of the hydraulic tubes, we will talk in another blog article later.
Hydraulic Tubes processing, like Cutting, bending, welding
The processing of pipes mainly includes cutting, bending, welding and so on. The quality of the pipe processing has a great influence on the parameters of the pipeline system, and it is related to the reliable operation of the hydraulic system. Therefore, scientific and reasonable processing methods must be used to ensure the quality of processing.
