Revolving Joint

High temperature revolving joint is small, light, and has a small friction moment. It adopts reliable ball surface friction seal configuration, it can be concentric automatically and compensated automatically. Reliable material can lower down wear effectively and prolong service life through fine grinding .This series of product is mainly used for blast furnace pipeline in steel factory, the sway times per minute is controlled continuously. its usage temperature is 350?Its performance is reliable, can be fit for pipeline corner, curve or vibrated places, playing an important role of cracking, damaging or pulling pipeline, so it can be widely used in fields of spaceflight, steel, metallurgy, chemical industry, electric power etc.

Our company was established in 1985,located in the first batch of reform and opening to the outside cities in China(China Valve City)--- WenZhou.
