Name: High Pressure Hydraulic Tubing/ Hydraulic Steel Tube / High Pressure Precision Cold Drawn Tubing
Place of Origin: China
Brand Name: Datong
High pressure hydraulic tubing is made of cold drawn seamless precision tubes according to DIN 2391 made of toughened steel (ST37.4 and ST52.4).Available (external diameter) from 6 mm to 42mm with different wall thicknesses and lengths to 6 meters. The hydraulic steel tubing has a tensile strength greater than comparable annealed tubing. Our high pressure hydraulic tube is available in a range of size and pressure ratings and can be used in a wide variety of applications.
As a professional high pressure hydraulic tubing manufacturer and supplier,Datong has been supplying and exporting high pressure hydraulic steel tubes for almost 20 years.

There are two type of material grade for hydraulic steel tubes, ST52.4 and ST37.4. ST52.4 is high tensile strength tube means it has higher permissible working pressures by reduced tube wall thickness, and leading to reduced system overall weight.
