High-Quality Stub End Flanges

Stub end flanges are also known as lap-joint flanges; use them with a stub-end straight adapter (not included). The stub-end straight adapter slides into the flange and welds to pipe (not the flange). Since the flange isn't welded to the pipe, it can be disconnected easily for frequent cleaning and inspecting. Forged flanges have better strength than cast flanges.

 Excellent Sealing Performance: Precision machining creates a smooth, flat sealing surface. Compared to traditional welded flanges, this eliminates potential welding defects, effectively improving the sealing performance of the joint and reducing the risk of leakage.
 Strong Corrosion Resistance: Typically constructed from high-performance materials such as stainless steel, these flanges withstand long-term use in highly corrosive environments, are less susceptible to corrosion damage, and thus extend the overall service life of the piping system.
 Adaptable to Various Operating Conditions: Customizable to suit various pipe sizes and pressure ratings, they can accommodate a wide range of operating conditions, including high and high pressures, as well as low and low pressures. They maintain a stable connection even in environments subject to significant vibration and shock, ensuring the safe operation of the piping system.
 Reduced Fluid Turbulence: Their geometry matches the pipe's inner diameter, and their tapered ends gradually change the flow direction of the fluid within the pipe, minimizing turbulence and erosion at the joint and helping to maintain smooth fluid flow.
