SPIRAL VANE INTERLOCK SPIROLATOR
THE TYPE 349 SPIRAL VANE INTERLOCK SPIROLATOR IS A TWO SEGMENTED, HINGED, RIGID SPIRAL-VANE SPIROLATOR DESIGNED FOR SEVERE LOADING CONDITIONS WHERE POSITIVE STAND-OFF OF THE CASING IS DESIRED.

The Type 349 is made from a fully welded construction and features solid steel vanes rather than formed vanes as used on the Type 340 stand-off band. The hinged design makes this Spirolator ideal for use on external upset tubing strings.
