EP TUBES

EP Tubes (electrolytic tubes)

EP tubes has stable chemical property, high pressure-proof ability, high strength, low resistance, widely used in special gas systems,medical devices,semi-conductor and liquid crystal industry.

Mechanical Properties:can adjust HRB(75~580)figures、tensile properties and elongations.

Heat Treatment:Solution in reducing atmosphere

Precise BA tubes
