A flange is a component that connects pipes, valves, pumps and other equipment. It usually consists of two interconnected circular or square planes that are bolted together. Gaskets or sealing strips can be installed at the seal. Flange connection allows for easy disassembly, repair and replacement of equipment. Depending on their structure and purpose, flanges can be divided into plate flanges, butt-weld flanges, threaded flanges, socket-weld flanges, slip-on flanges and other types.
1. Function
(1) Connecting pipes
Flanges are one of the most common ways to connect pipes, especially in the industrial field. By selecting the appropriate specifications and materials for the pipe, the firmness and sealing of the pipe connection can be ensured.
(2) Connecting valves
When installing valves, using flange connections can make them easier to replace or repair.
(3) Connecting equipment
Flanges can also be used to connect equipment such as pumps and compressors to ensure the firmness and sealing of the equipment connection.
(4) Installing measuring instruments
In some cases, it is necessary to measure and monitor parameters such as flow and pressure in the pipeline. In this case, measuring instruments can be installed at the flange connection to facilitate data collection and analysis.
(5) Brackets and fixings
When installing pipelines or equipment, flanges can be used as brackets and fixings to enhance the stability and firmness of pipelines and equipment.
2. Application areas
(1) Petrochemical industry
Flanges play an important role in pressure bearing, force transmission and sealing in the oil and natural gas extraction, refining, storage and other industries. Since the liquid and gas media involved in the petrochemical industry are relatively complex, the sealing requirements for flanges are very high. Therefore, this industry has a great demand for high-quality, safe and reliable flange products.
(2) Shipbuilding
A large number of flanges are used to connect ship pipes, hatches, valves and other equipment. Their quality and performance are directly related to maritime safety. In order to meet the needs of ship use, various flange products must undergo special treatment and material selection to meet the qualified standards.
(3) Construction industry
Many equipment and pipelines in the construction industry also need to be connected using flanges, such as pipeline transportation, heating, refrigeration, ventilation, etc. The pressure and temperature generated during the operation of these equipment will bring high requirements to the performance of flanges.
