SEALING
• Join the two ends as shown in the sketch ( Image 2 , Fig . 2 ). The bolts should be torqued in a star pattern . This should be done in three stages , torquing to approximately 25 % of the total required torque value with each round . The fourth and final adjustment should be made in a circular direction to the full torque value .
• Two tape strips can be used for particularly difficult sealing problems ( flange rotation , vibrations , or similar ) ( Image 2 , Fig . 3 ).
Final thoughts
Expanded PTFE gasket-tape offers significant benefits across various industrial applications , particularly when custom dimensions or emergency repairs are required . The choice between mono-axial and multi-directional ePTFE tape depends on the application ’ s specific needs . Mono-axial tape provides flexibility and ease of installation , while multi-directional tape excels in environments where strength and dimensional stability are paramount . By understanding each ePTFE tape ’ s unique properties , engineers can select the right one for their specific sealing requirements , improving both efficiency and safety .
