Flanges are components in pipe systems that hold pipes together with modified faces, collars or processes. As a Carbon Steel Flanges manufacturer we produce flanges of different types to be used in different applications. The Carbon Steel Flanges have high wear and tear resistance. They have less corrosion resistance compared to most stainless steels and have less strength compared to some special alloy material, but they are of high cost efficiency. There are different types of flanges used in different applications. Our Carbon Steel Blind Flange is used to close a pipe line in a system. The blind flange has a flat end with which it closes the pipe.

There are Carbon Steel Slip On Flange types which allow pipes to slip through them so the connection could be made in the desired locations. Most flanges are welded together with the pipe for maximum and permanent connectivity. The Carbon Steel Puddle Flange is used to connect two pipes and seal them tight by holding the ends of pipes inside the flange structure. The Carbon Steel Weld Neck Flange has a welded neck that increases the grip with the pipes and welding surface. Our Low Carbon Steel Forged Flange has comparatively higher corrosion resistance and strength but low wear and tear resistance. Please contact us for further information on carbon steel flanges.

Carbon steel flange has a much better tensile strength, it lacks the corrosion-resistant properties, Although it’s stronger and more durable than stainless steel.
