Flanges are basically used to join two different pipes with each other with the help of bolts and not by welding or threading. They can be used to join two pipe ends either of same size or different. They have an external or internal ridge / rim for joining. These rings also acts to provide strength to the flange or pipes. These products are made up of steel and can be used to join a system with the existing product. They provide a facility to form fittings for pipes that can be easily assembled and disassembled with the help of these flanges.
