Stationary tube plate type:
The tube plate and case are welded together. The launders on both ends of pipe
side are flange type connected to tube plate by screw. The flow way of launder 
can be multi-tube type. The expanding coupling added on case can eliminate the
stress generated by the thermal expansion difference of interior tube and case.

Floating head type:
The tube and case floating-head type heat-exchanger are separated. The
floating tube plate is freely fluctuating for elimination of the thermal expansion
difference of case and tube. This design is widely used in petroleum refinery.

U-tube type:
U-type heat-exchanger consists of a stationary tube plate, U-tube, damper, 
dead lever and spacing ring. Other tubes cannot influence the expansion and
shrinkage of each tube.
