flangesamling

A flange assembly, often referred to as a flanged joint, is a method of connecting pipes, valves, pumps, and other equipment to form a piping system. The core components of a flange assembly are flanges, gaskets, and fasteners. Flanges are typically ring-shaped devices that are welded, screwed, or forged onto the ends of pipes or equipment. They have a flat or raised face that provides a sealing surface.

Gaskets are placed between the mating faces of two flanges to create a seal and prevent leakage. Gaskets are made from a variety of materials, including rubber, PTFE, metal, and composite materials, chosen based on the fluid, temperature, and pressure of the application. Fasteners, such as bolts and nuts, are used to draw the flanges together, compressing the gasket and creating a tight seal. The number and size of fasteners are determined by the pressure rating of the flanges.

Flange assemblies are common in many industries, including oil and gas, chemical processing, water treatment, and power generation. They offer advantages such as ease of assembly and disassembly for maintenance or inspection, and the ability to handle high pressures and temperatures. However, proper installation is crucial to ensure a reliable seal and prevent leaks. Incorrect bolt tightening, improper gasket selection, or damaged flange faces can all lead to joint failure. Various types of flanges exist, including weld-neck, slip-on, threaded, socket-weld, and blind flanges, each suited for different service conditions and installation methods.
