Tätningsytan
Tätningsytan is the contact surface on a component that forms a seal with a mating surface or sealing element to prevent leakage of fluids or gases under operating conditions. It is critical in joints using gaskets, O-rings, or lip seals, and is designed to be flat, parallel, and free of defects so that the sealing element can deform properly under clamping force.
Design features include surface flatness and planarity, perpendicularity and parallelism to the mating face, and an
Manufacturing and inspection: Tätningsytan is produced by machining processes such as turning, milling, grinding, lapping, or
Operation considerations: Sealing performance depends on gasket material, clamping pressure, temperature, pressure, and chemical compatibility. Proper
Standards: Many industries reference standards specifying acceptable surface finishes for sealing faces, including flange and valve
