What Are Slip On Flanges?
Slip on flange is a common pipe connection flange that is fixed to the pipe or equipment by flat welding. Slip On flanges strike a balance between cost and performance, making them ideal for low and medium pressure piping systems.
Made from aluminum alloy, aluminum slip on flanges are built to withstand various environmental conditions, ensuring longevity and durability. The primary characteristic of these flanges is their ability to easily slip over the end of a pipe. Once positioned, they are welded inside and outside, creating a secure and sturdy joint. This dual welding process not only enhances the strength of the connection but also significantly reduces the risks of leaks, making these flanges an essential component in any piping system.
Slip On Flange Structural Features:
- Short Neck Design: With a short conical neck that matches the outside diameter of the pipe to provide structural support.
- Welding method: The flange bore is set outside the pipe and is welded by an external fillet weld (usually one side only) without the need for beveling.
- Sealing surface type: common flat surface (FF), convex surface (RF) or concave-convex surface (MFM), selected according to requirements.
- Flange holes: bolt holes are evenly spaced for easy alignment and installation.
