Gasket XT1 is an improved innovation of traditional double jacketed gasktes.
Structurally, it is much more resistant, since it has the most extensive seams that prevent the opening of the “Jacket”.
Between the two inserts of Grafoil it is inserted a layer of “Metal” which strongly reduces the extrusion (when the thickness of the Grafoil is lower, the tendency to extrude is less).
Both mentioned features allow the gasket to retain its original width, and even under high loads not by cracking at the edges; phenomenon that often leads to collapse most of normal double jacketed gasket.
The crossbars are obtained from straight elements, joined together and to the circular part of the gasket, by brazing.
The innovation in the joining system between the cross bar and the circular part, makes the gasket homogeneous, on the whole circumference, as no longer influenced by cross bars made from the whole piece.
Thanks to the use of the coating with Grafoil Silver adhesive, applied on both faces of the gasket, since it is not a corrugated tape, it gives the best alignment capability, and a greater adaptability to irregularities of the sealing surfaces of the flanges.
The use of this coating is in accordance with what is reported in the Standard ASME PCC-1 ed. 2019 [P-4.5.1].
