Flanges are used to connect valves, pipes, pumps and other equipment to make a pipework system. Typically flanges are welded or threaded, and two flanges are connected together by bolting them with gaskets to provide a seal that provides easy access to the piping system. This is when you need flange drilling services!
With a protruding ridge or rim, they are often used to increase strength or spread the load.
For example, sectional beams often have flanges that carry most of the load and that are connected by a web joining the flanges together. Pipes may also be fitted with flanges, which provide attachments. Nuts and bolts may include flanges to spread the clamping force over an increased area.
Flanges are the second most used joining method after welding. They are used when joints need dismantling. It provides flexibility for maintenance.
A flanged joint comprises of three components; flanges, gaskets, and bolting and assembled by a pipefitter. Special controls are required to select and apply all these elements to attain a joint, which has acceptable leak tightness.
Pipe flanges form a rim that radially protrudes from the end of a pipe. They have several holes that allow two pipe flanges to be bolted together, forming a connection between two pipes. A gasket may be fitted between two flanges to improve the seal.
Pipe flanges are available as discrete parts for use in joining pipes. The pipe flange is attached permanently or semi-permanently to the end of a pipe. It then facilitates easy assembly and disassembly of the pipe to another pipe flange.
Pipe flanges are classified according to how they are attached to the pipe. The different types of pipe flange and their specific differences and purpose include:
Flanges are typically manufactured from different materials such as carbon steel, low alloy steel, stainless steel, duplex steel, monel, inconel, hastelloy or nickel.
