Vssja flange limit

Flange limit expansion joint is composed of body, sealing ring, gland, expansion pipe and other main parts.

The pipeline can expand freely in the allowable expansion amount. Once it exceeds the maximum expansion amount, it will play a limiting role to ensure the safe operation of the pipeline. It is especially suitable for the connection in the pipeline with vibration or certain slope and bend. It is suitable for transporting seawater, fresh water, cold and hot water, drinking water, domestic sewage, crude oil, fuel oil, lubricating oil, product oil, air, gas, steam and granular powder with temperature not higher than 250 ¡æ.
