Hastelloy B-3 Stub End Astm B366 Wear-Resistant Pipe Fittings
Stub end is a special type of pipe connection in pipe fittings. It is usually used in pipe systems where valves, flanges or other pipe equipment need to be connected. The main functions and features of Stub end include:
-
Connection function: Stub end can be used as a connecting component in the pipeline system to connect pipelines and other equipment, such as pumps, valves, etc. It is usually used in conjunction with flanges and bolts to achieve a sealed connection in the piping system.
-
Convenient Maintenance: The design of the stub end allows for easy replacement or maintenance of connected equipment without the need to disassemble the entire duct system. This design is particularly suitable for parts of pipes that frequently require inspection or replacement.
-
Stress Reduction: In piping systems, pipes may develop stress due to temperature changes or fluid dynamics. Stub ends can help disperse these stresses through their structural design, thereby reducing potential damage to the piping system.
-
Corrosion resistance: Stub ends are usually made of stainless steel or other corrosion-resistant materials, which makes it particularly useful in environments exposed to corrosive media, such as chemical, petrochemical and other industries.
-
Adaptability: Stub ends can adapt to pipeline systems of different sizes and pressure levels, with good adaptability and flexibility.
