Specialized copper flanges are used in plumbing and piping systems to join pipes or other components. These flanges, usually composed of copper alloys, have a flat, circular disc with bolt holes placed uniformly around the edge. They can be securely fastened using bolts or welding since they are made to be fastened to the ends of pipes or other equipment. Copper flanges have multiple functions, such as making pipe systems more accessible to assemble and disassemble, providing a sealing surface to stop leaks, and enabling the attachment of extra parts like valves or instruments. Copper flanges are extensively used in many industries where dependability and durability are crucial due to their resistance to corrosion, thermal conductivity, and adaptability.

The pipes or equipment that has to be connected must first have their mating surfaces cleaned and cleared before installing copper flanges. The flange gaskets are then positioned to provide a seal between the mating surfaces. To firmly hold the copper flanges in place, bolts are put through the holes in the mating surfaces in line with them. A steady, leak-free connection can be achieved by carefully and evenly tightening the bolts. Additional sealing techniques, such as soldering or welding, may be used, depending on the application, to improve the security and integrity of the connection. Regular maintenance and inspections are recommended to guarantee the copper flange installation's continued dependability and functionality.

Various copper flange types meet diverse needs in piping and plumbing systems. The long neck of weld neck flanges allows for high-pressure applications, giving the joint strength and structural support. Perfect for low-pressure applications, slip-on flanges slide over the pipe and are fastened using fillet welds on both the inside and exterior. Threaded flanges are ideal for small-bore piping systems because their internal threads match the external threads of the pipe, making assembly simple and requiring no welding. To provide a smooth flow channel, socket weld flanges are similar to slip-on flanges but feature a recessed section to fit the pipe's end. Lap joint flanges comprise a backing flange and a stub end. This design reduces joint stress and makes alignment and assembly simple. These various copper flange types provide adaptability and flexibility to satisfy the requirements of piping systems in various industries.
