ABOUT OUR SEAL


Fixing Concept :

The fixing execution of flexible Metal Seals depends on a the relative high particular contact load at the fixing line and a specific versatility or spring back of the versatile metal seal. 

The seating load and the comparing fixing line width, are a component of the chose seal sort, cross area, material, material thickness and the composite properties itself. 

Contingent upon the required snugness and the media to be fixed, a particular seating burden will be required. Plating or covering with delicate, bendable material will give better fixing by topping off score blemishes. The seating burden will make the pliable layer to stream and top off the section surface anomalies. 

Versatile Metal Seals require a controlled pressure. Regularly these seals are introduced in a machined groove, or the pressure is restricted by a supposed retainer plate.





Exceptions And Particular Cases :

Resilient Metal seals often have to perform under extreme service conditions. Standard solutions as found in this catalog may not always suffice this requirements.

HTMS Futom can alter the standard design and materials to optimize seal performance for a given application.

With high accuracy and backed by FEA in cooperation with the University, HTMS Futom can adjust the seals cross section, wall thickness, selected alloys, to name a few, in order to adapt seal performance to the variables in service.

FUNCTION OF A SEAL :






The fixing execution of flexible Metal Seals depends on a the relative high particular contact load at the fixing line created by the pressure of the seal to a specific furrow profundity and a specific strength or spring back of the versatile metal seal. 

Commonly strong metal seals are compacted 20%. For instance a 3,18 mm FH (free stature) seal is compacted to around 2,5 mm. 

• Point B delineates the most extreme depression profundity. Now the seating load as of    now passed 90% of its maximum.
• Point C outlines the base section profundity, or the point where the seating load achieves its most extreme. 
  Diminishing the depression profundity considerably more and along these lines expanding the pressure proportion can prompt seal failure.
• Point D At this point the seals' strength conquers the rest of the (decompression) stack, this versatility is called springback.
• Point E Springback of the seal at 20% of the most extreme burden (Lmax) is the valuable springback.
• Point F Springback of the seal at zero burden is all out springback = flexible recuperation of the seal
