High Safety Margin Alloy Steel Flanges ANSI B16.5 DN80 Class 150
1. Product Description
An Alloy Steel Flange is a piping component made from alloy steel used to connect pipes, valves, pumps, pressure vessels, and other equipment to form a complete piping system. It creates a detachable, sealed, and pressure-bearing connection point by securing two flange faces with bolts and a gasket between them. Its core value lies in its ability to withstand high temperatures, high pressure, and extreme operating conditions, making it a critical foundation component in heavy industries like power generation, petrochemicals, and oil & gas.
