flangühendused

Flangühendused, often referred to as flange connections, are a common method for joining pipes, valves, pumps, and other equipment to form a piping system. They consist of a flange, a gasket, and studs or bolts. A flange is a projecting rim or rib on an object, typically for strengthening or attachment. In piping, flanges are typically welded or screwed onto the ends of pipes.

A gasket is placed between two mating flanges to create a seal. The gasket material is chosen based on the fluid being transported, temperature, and pressure. Common gasket materials include rubber, PTFE, and various composite materials. The flanges are then drawn together by bolts or studs that pass through holes in each flange. Tightening the bolts compresses the gasket, creating a leak-proof joint.

Flange connections offer several advantages. They are relatively easy to assemble and disassemble, making maintenance and modifications simpler. They can be designed to withstand high pressures and temperatures. The variety of flange types, such as weld-neck, slip-on, threaded, and lap joint, allows for flexibility in system design and installation. Different flange standards, like ANSI/ASME and DIN, ensure interchangeability and compatibility between components from various manufacturers. However, flange connections can be more expensive than welded joints and require careful installation to ensure a proper seal.
