Carbon Steel Slip on Flange is a type of pipe fitting commonly used in the piping systems of industrial and commercial settings. It consists of two parts a slip-on hub that contains threads, and a flange which provides an airtight seal at the designated point. In essence, this form of flange acts like a clamp for pipes so there is no need for welding or threading when connecting pieces together. The ASTM A105 Slip On Flange also has excellent corrosion-resistance due to its carbon steel material construction, making them suitable for both indoor and outdoor applications. They are designed with slightly raised faces on either side allowing easy installation with accessories such as gaskets or o-rings to ensure an even better seal between connected components. Overall, Carbon Steel Slip On Flanges offer superior strength, durability and cost efficiency compared to other types of pipe fittings.
