Tristar Special Expanders

    

Apart from the Standard Series of Tube Expanders due to Continuous R&D, We have Successfully Designed Special Tube Expanders to Suit Specific Applications .

   
  

DIESEL ENGINES EXPANDER
 A Special Series of Tube Expanders designed for rolling the injection sleeves into the head of Diesel engines. These Tube Expanders are made to order for each application, and a detailed drawing of the injector sleeve and the engine head must accompany the order to ensure proper Tube Expander Design.
 
   

STEP ROLLING EXPANDER
Ideally suited for faster Tube rolling in Tube Sheets that are 10" (250 mm) and thicker without removing the Tube Expander cage has grooves spaced 1" apart and is fitted with a spring-loaded, quick spacing thrust collar that permits fast step rolling in 1" increments throughout the full thickness of the Tube Sheet. 

 

   
  

TVN EXPANDER
A Special Tube Expander which has roll-slots positioned such that the mandrel is not self feeding. The Tube expanding Machine used with these Expanders applies two separate forces to the Mandrel. One force rotates the Mandrel and the other force moves the Mandrel longitudiually to achieve Tube Expansion. The Rolls and the Mandrel are made from High Speed Steel.
