SU / TM series: Comparison
Toray offers most of its standard 8″ elements with a new flush cut design. The anti-telescoping device (ATD) on new TM elements provides improved face-to-face contact for hydraulic loading, providing more uniform distribution of the loads.
These new flush-cut elements are fully compatible with many other elements in the industry. With its new flush-cut elements, Toray has set its sights on how internal sealing is done, thus ensuring the highest degree of integral sealing between elements within the pressure vessel.
- Toray 4″ and 8″ TM Type
- Toray 4″ and 8″ SU Type
