Pipe flange is a mechanical component used to connect pipes, valves, pumps, and other equipment in piping systems. Flanges provide easy access for inspection, maintenance, and modification of piping systems.
Industrial pipe flanges are manufactured in various types such as weld neck flange, slip on flange, blind flange, socket weld flange, threaded flange, and lap joint flange. Each type is designed for specific pressure ratings and installation requirements.
Most industrial flanges follow international standards such as ASME B16.5, ASME B16.47, and material specifications according to ASTM standards.

Pip Valcon have stocks for most used flange types in Petro and chemical industry such as Welding Neck (WN Flange), Slip On (SO Flange), Socket Weld (SW Flange), Lap Joint Flange, Threaded / Screwed Flange and Blind Flange. See image below:
all flanges are provided with a raised face except the Lap Joint Flange.
Materials for Flanges
The most used material is forged carbon and stainless steel, and have machined surfaces. The material of a flange, is basically set during the choice of the pipe, in most cases, a flange is of the same material as the pipe.
Bolted Flange connections
A bolted flange connection is a complex combination of many factors (Flange, Bolts, Gaskets, Process, Temperature, Pressure, Medium). All these various elements are interrelated and depend upon one another to achieve a successful result.
The reliability of the flanged joint depends critically upon competent control of the joint making process.
