Flänsiliitosten

Flänsiliitosten, often translated as flanged joints, are a common method for connecting pipes, valves, pumps, and other equipment in industrial and mechanical systems. They consist of three main components: flanges, gaskets, and fasteners. A flange is a projecting rim or edge, typically attached to the end of a pipe or fitting, designed to provide a means of connection to another flange. Gaskets are sealing elements placed between the mating flange faces to create a leak-proof seal. Fasteners, usually bolts and nuts, are used to draw the flanges together and compress the gasket, creating the required sealing pressure.

The primary advantage of flanged joints is their ease of assembly and disassembly. This allows for maintenance, repair, or replacement of components without requiring the cutting or welding of pipes. They also offer a reliable and strong connection, capable of withstanding significant pressure and temperature variations, making them suitable for a wide range of applications. The choice of flange type, gasket material, and fastener specification is crucial and depends on the operating conditions of the system, including pressure, temperature, fluid type, and environmental factors. Common flange standards, such as ANSI/ASME and DIN, ensure interchangeability and compatibility between components from different manufacturers. Proper installation, including correct bolt tightening sequences and torques, is essential for achieving a secure and leak-free joint.
