Core Functions of Tang End

1) Permanent Embedding & Fixation The short tang-end thread can be screwed tightly into the tapped holes of equipment bodies or pressure vessel shells to realize permanent installation, and frequent disassembly is not required.
2) Simplified Assembly Operation After the tang end is fully embedded into the workpiece, only the opposite threaded end is exposed outside. Workers only need to install nuts on this single side to clamp flanges, cover plates and other components, which greatly cuts down assembly time and labor cost.
3) Excellent Anti-loosening Performance The tang end adopts interference-fit thread tolerance.
4) It can effectively resist loosening generated by mechanical vibration, and is perfectly applicable to harsh working conditions including high-temperature & high-pressure pipelines, pumps, heat exchangers and pressure vessels.
