Pipe Flange Basics

November 12, 2014 in Blog, Valves and Fittings by

FlangesPipe flanges are an important parts of piping systems. Some flanges are bolted together to form connections between pipes, while others–blind flanges–are used to cover or close the end of pipes.

One main advantage of using pipe flanges is that they make it easy to inspect, modify or clean pipes. Furthermore, using flanges means that you don’t have weld pipe spools, and they also make blasting, painting and NDO simpler and more convenient.

Pipe flanges, however, do have a few disadvantages. Their primary drawback is that they may be slightly more prone to leaking than other methods of connecting pipes. They also usually take up more space than their alternatives.

For high temperature and pressure treatment, consider purchasing high pressure steel flanges that comply with ASTM, ASME, ANSI and/or API standards.

API vs. ASME/ANSI standards:

Flanges meeting API standards can withstand high pressures and temperatures. The main difference between flanges that meet API standards and those that meet ASME or ANSI standards is the material used that can handle a high-pressure environment. Typically they are more efficiently used in dealings with gas and oils. When working with water, air, and steam in an industrial setting, ASME/ANSI flanges are more common.
