The
spherical joint has the advantages of simple construction, good mechanical performance, disassembling, fatigue resistance, and not loosening under dynamic load, so it is a promising connection method.
Spherical joint is a kind of equipment to solve the thermal expansion and cold contraction of pipelines. It can be widely used in metallurgy, petroleum, chemical industry, electric power, light industry, textile, construction and national defense construction and other industries. The specific uses of spherical joint are as follows:
1. Used in heat pipe to compensate thermal expansion.
2, used for rocket launch pad, aircraft exhaust facilities, compensation impact expansion.
3, used for metallurgical equipment (such as blast furnace, converter, electric furnace, heating furnace, etc.) vaporization cooling system and coal ash conveying pipeline system for universal joint.
4, used in various pipelines of buildings, to prevent uneven subsidence of the foundation, or earthquake and other unexpected reasons to damage the pipeline.
