Stainless Steel Hydraulic Round Pipe
SS Hydraulic Tubing
Stainless steel hydraulic pipe is one of the commonly used pipe materials in hydraulic systems. Due to its excellent corrosion resistance and sufficient strength, it is widely used in various hydraulic equipment.
Stainless steel hydraulic pipes are usually made of 304, 316, 316L and other stainless steel materials. These materials can maintain good corrosion resistance in humid, acidic, alkaline and other environments and are not easily corroded, thereby extending the service life of the hydraulic pipes.
In addition to corrosion resistance, stainless steel hydraulic pipes also have good mechanical properties and pressure resistance. It can withstand the high pressure commonly found in hydraulic systems, ensuring the stable operation of the hydraulic system and preventing damage caused by pressure fluctuations. In order to improve the surface finish and corrosion resistance of stainless steel hydraulic pipes, surface treatments such as polishing and pickling are usually required.
In the process of producing and using stainless steel hydraulic round pipes, relevant standards and specifications must be complied with. These standards and specifications specify the chemical composition, mechanical properties and manufacturing processes of pipes, thus ensuring product quality and reliability. For example, standards such as ASTM A269 and ASTM A312 are commonly used standards for stainless steel hydraulic pipes. They clearly specify various performance indicators of pipes.
