Flanges are integral components used in piping systems to connect pipes, valves, pumps, and other equipment. They provide a method for joining two pieces of pipe together, either by welding, threading, or bolting. Flanges also allow for easy access for inspection, cleaning, or modification of the piping system.
Flanges are available in a wide range of materials, including carbon steel, stainless steel, alloy steel, brass, bronze, and plastic. The choice of material depends on factors such as the fluid or gas being transported, temperature, pressure, corrosion resistance requirements, and budget considerations. Flanges have bolt holes drilled around the circumference, allowing bolts to pass through and secure the flanges together. The arrangement of bolt holes follows a standard bolt circle diameter, determined by the flange size and pressure rating. Common bolt circle standards include ANSI, ASME, and DIN.
The manufacturing process of flanges involves several steps to produce these critical components used in piping systems. Here's an overview of the typical manufacturing process:
By following these steps, We produce high-quality flanges that meet the stringent requirements of piping systems in various industries.
