Description
PJ-RJ flange is relatively simple to manufacture and is mainly applicable to the pipeline system with corrosive medium.
Different materials can be used for flange and flat welding ring, so the number of stainless steel can be saved, the cost of flange can be reduced, and the service performance can be improved.

Characteristic
PJ-RJ flange is a movable flange, which is generally matched with water supply and drainage accessories.
When the manufacturer leaves the factory, there are flanges at both ends of the expansion joint, which are directly connected with the pipe fittings and equipment by bolts.
The purpose of using flat welding ring loose flange is usually to save material.
Application
PJ-RJ flange is widely used in oil and gas pipeline engineering, natural gas pipeline, chemical plant, power plant, shipyard, pharmaceutical, dairy, beer, beverage, water conservancy and other fields.
