Compact flange

The compact flange is based on NORSOK l005 standard and is suitable for use in severe sealing environments with thermal expansion or fluid cycling loads.
DETAILS:

The compact flange is based on NORSOK l005 standard and is suitable for use in severe sealing environments with thermal expansion or fluid cycling loads, such as risers, single point mooring systems, manifolds, Christmas trees, subsea pipelines, heat exchangers, and other piping systems in various process industries.

The design principle of compact flange is double sealing system with independent flange sealing surface. The root of wedge-shaped flange face forms a seal due to the pressure brought by bolt pre tightening force; the main seal is IX sealing ring, and the sealing force mainly comes from the elastic energy of the sealing ring under its own stress state. If the wedge flange root seal leaks, then the pressure from the inside expands to the outer diameter, thus improving the sealing effect.
