Flanges are a reliable method of connecting pipeline systems with various equipment, valves, and almost all other processing system components, and they are the most widely used connection method after welding.
Flanges make it easier to disassemble and improve access to system components, thereby increasing the flexibility of maintaining pipeline systems.
A typical flange connection consists of three parts:
Pipe flange
Gasket
Bolt
In most cases, there are specific gasket and bolt materials that are the same or approved as the pipeline components you want to connect. Stainless steel flanges are one of the most common types of flanges. However, there are many flange materials, so you must match them to your needs.
Other common flange materials include monel alloy, inconel alloy, chromium molybdenum alloy, and many other materials, depending on the application.
The most suitable choice for your needs depends on the system you plan to use with flanges and your specific requirements.
