In numerous industrial fields such as rubber and plastic, leather, textiles, dyeing and printing, chemical engineering, and new energy, thermal oil (heat transfer oil) is used as an efficient heat transfer medium and is widely applied to various rotating equipment that require heating, such as calendering machines, plastic mixers, drying drums, etc. And the thermal oil rotary joint is precisely the key "joint" that transfers these high-temperature heat transfer oils from static pipelines to rotating rollers.

Steam rotary joints are widely used in heavy industries such as papermaking, textile, dyeing, rubber vulcanization, and steel metallurgy. Stable heat energy transmission is the key factor ensuring production efficiency and product quality. The steam rotary joint, as the crucial sealing component connecting the stationary steam source and the rotating drum, acts as a "heat energy bridge". Although it seems to be just a small mechanical component, it directly determines the energy efficiency ratio and operational stability of the entire heating system.
