Seamless Hydraulic Tubing (SAE J-524) covers cold drawn and annealed seamless low carbon steel pressure tubing intended for use as hydraulic lines and in other applications requiring tubing of a quality suitable for flaring and bending. All material is dead soft annealed and drawn. Has uniform ductility and a smooth clean inside surface.

Seamless hydraulic tube

seamless hydraulic tube application

Hydraulic seamless tubes are widely used in petrochemical industries, refineries, power industries, chemical industries, aerospace industries, automotive industries, etc. Heat exchanger tubes, hydraulic tubes, boiler tubes, mechanical tubes, finned tubes, etc. required in these industries are hydraulic seamless tubes.

How to make hydraulic tube

The tubes surface finishing is NBK, where the tubes are phosphate and normalized which provides corrosion resistance. It is oiled inside and outside. Normalize process creates tougher metal product. During normalizing, metals will be heated at a high temperature, and it allowed to naturally cool back down to room temperature by exposure after heating. Metals that have been through this process are more formable, harder and ductile.
