Copper flanges are components used in plumbing systems to connect pipes, valves, and equipment together. Made of copper - an exceptional metal known for its diverse uses - one key characteristic of these components is machinability: copper is relatively easy to machine which allows precise shaping and customization to suit specific requirements.
Copper flanges stand out with their exceptional corrosion resistance. Copper provides great moisture or chemical exposure resistance that ensures long term reliability even under harsh environments. This characteristic also ensures flange longevity for various applications in difficult circumstances.
Copper flanges' weldability is an integral aspect of their design, enabling them to quickly be attached to pipes or fittings through welding processes such as brazing or soldering for fast installation with secure, leak-free connections ensuring efficient use in any piping system. This feature ensures efficient installation while supporting its integrity as a whole.
Due to their special properties, copper flanges offer numerous advantages. Not only is copper machinable and corrosion-resistant, but it also provides outstanding thermal and electrical conductivity, antimicrobial properties, and aesthetic appeal—qualities that make copper flanges highly sought-after across various industries and applications.
Copper flanges find uses in industries as diverse as plumbing, HVAC (heating, ventilation and air conditioning), refrigeration and industrial processes. Common applications for copper flanges in residential settings, commercial businesses or chemical processing plants includes connecting pipes in water supply systems or HVAC/R systems that control temperature or conditioning levels and chemical processing plants - among others.
Copper flanges have a range of applications in which durable, corrosion-resistant piping connections are essential, including water distribution systems, refrigeration units, heat exchangers, air conditioning and hydraulic systems - in industrial settings they're frequently found at oil and gas refineries, power plants and manufacturing facilities to transport fluids or control them.

Raw Material
At the very first process, the system controls check the quality of supplies raw materials as per the test certificate and also visual and dimension.
Material Inspection
Incoming quality control (IQC) is the process of observes the quality of materials and parts for manufacturing a product before production starts.
Material Cutting
In this process refers to manufacturing flanges by cutting stripes from the middle plate and then rolling them into round shape.
Flange Forging
Forged flanges generally have lower carbon content than cast flanges and are less disposed to rust. In Forgings Material Grade Check, weight measuring, and control the temperature.
Final Inspection
In this method measure & inspect the dimension & size of the flange. The diameter is check to control what size pipe a flanges can be used.
