Function Introduction |
Stub-end is a pipe fitting that forms the edge of the pipe mouth into a vertical edge along a specific curve through stamping or welding. It is mainly used for connecting pipes with flanges, valves, or other pipe fittings to enhance sealing and structural strength. Its design replaces complex drawing processes, optimizes material plastic flow, avoids cracking or wrinkling, reduces processing steps, and saves materials. It is especially suitable for high-pressure, corrosion-resistant, or precision fluid delivery systems. |
|
Application fields |
Widely used in pipeline system connections in the fields of petrochemicals, natural gas transportation, electric power, shipbuilding and municipal engineering, suitable for high pressure, high temperature and corrosive media environments. |
