Plate flanges are very popular in different fields such as piping and manufacturing. The flanges are made of flat steel plates and are used in high-pressure scenarios such as welding and piping to connect pipes and various parts of the system.
There are several different materials, shapes, and sizes of metal rings available for selection to provide durability to strengthen the pipeline and maintain its connection with other components. When needed, through fastening and disassembly, the plate flange simplifies the installation process.
Plate flanges are commonly used in multiple industries, including the oil and gas industry, to connect and protect pipelines from external influences. This kind of flange is made from a flat piece of metal, it is round and has a larger circumference, which can withstand higher pressure levels. Its significant advantage lies in its durability, as it can establish a strong connection between pipelines of different sizes when facing severe temperature fluctuations. Plate flanges are versatile because they can be produced using various metals, including but not limited to carbon steel, stainless steel, and alloy steel.

Usage:
Plate flanges connect pipes, but they can also serve as connectors or seals for specific parts of various system components.
Plate flanges have a wide range of applications in the field of pipe fittings. They are an ideal choice when it comes to connecting metal pipes or different parts of a pipeline.
In addition, these flanges can separate two metal parts that need to be separated. Their versatility extends beyond metal pipes, as they can connect plastic pipes or even different parts of air conditioning or heating devices.
Pros:
1. Can be manufactured to create strong joints that can withstand high pressure and provide a reliable seal
2. Their thin and flat design saves space and money without compromising reliability
3. Flanges made from bent plates are stronger and less prone to corrosion or fatigue than those welded together
