Hydraulic Thrust Expansion System
Features
Specially designed to expand stainless steel thick walled and exotic harder tubes, where conventional expanders would fail. Can expand tubes in a deep channel using stepping extension.  Quality leak proof joint in 3 to 5 seconds. Precise control of advancing force. Constant RPM even under load condition ensures equal pressure to the rolls for tight fit, leak proof joint between tube and tube sheet. Internal cylindricity of expanded tubes. Durable heavy-duty construction ensures long reliable life. Reduction of tube stretching & internal stresses. Simple operation saves time & reduces operator fatigue. Large oil tank and external filter for better cooling effect and easy filter replacement. Automatic lubrication system increases tool life and reduces consumable cost. Continuous programmed cycle-microprocessor controlled.
