Product Description

A large-diameter flange is a special type of flange with a relatively large diameter. Typically, its nominal diameter is DN200 or greater. Large-diameter flanges are commonly used in equipment and piping systems that must withstand high pressure or high temperatures.

The main features of large-diameter flanges are their robust construction and ability to withstand high pressures. They consist of two flange discs and several bolts, which secure the two discs together. The sealing surfaces of large-diameter flanges typically employ either flat-face or raised-face designs, effectively ensuring the sealing integrity of the piping system.

Large-diameter flanges are widely used in pipeline systems across industries such as petroleum, chemical processing, power generation, and metallurgy. They enable the connection of pipelines, valves, pumps, and other equipment with varying diameters, ensuring high levels of safety and reliability for the entire system. Additionally, large-diameter flanges are easy to install and simple to maintain, helping to reduce overall system maintenance costs.

In summary, large-diameter flanges play a crucial role in the industrial sector. They not only facilitate the connection of various equipment and pipelines but also ensure the system’s sealing integrity and safety. As technology continues to advance, the design and manufacturing of large-diameter flanges are steadily improving, providing stronger support for industrial development.
