Flange element

An annular flange element for connection of tubular elements, the flange element comprising:

• an inner periphery arranged around a central axis,
• an outer periphery arranged around the central axis,
• an outer flange part extending radially outward toward the outer periphery, the outer flange part comprising an outer section of a rear side and an outer front side with an outer front surface for connection to a cooperating structure,
• an inner flange part extending radially inward toward the inner periphery, the inner flange part comprising an inner section of the rear side and an inner front side with an inner front surface for connection to the cooperating structure, and
• an attachment part extending from the rear side in a direction opposite the inner front surface and the outer front surface the attachment part being adapted for secure attachment to a tubular element, and
• wherein the inner and outer flange parts are partially divided by at least one annular groove extending between the inner and outer flange parts from a position between the inner front surface and the outer front surface towards a position a distance from the rear side,
• wherein the inner flange part and the outer flange part extend radially inward and outward, respectively, from the attachment part.
