Reel Swivels are mainly used on coiled tubing unit, with one end connected to coiled tubing, another end to surface manifold for pressurized rotary operation. Jereh Reel Swivels feature excellent sealing capability and corrosion resistance. Main sealing area surfaces are handled by special technology to increase corrosion resistance. Jereh offers two basic structure types-U shape and L shape, suitable for standard service and H2S service. Customized design is also available to meet various demand.

Check Valves are widely used in high pressure lines to control one-way flow and prevent fluid from flowing back to the pump, thus to protect pipeline safety. Jereh Check Valves include top-entry check valves, in-line flapper check valves and dart check valves. Flappers of top-entry and in-line flapper check valves which are mainly used in fluid condition adopt complete coating design, increasing service life. Dart check valves are mainly used in air condition.

Safety Valves act as a fail-safe for reciprocating plunger pump, pressure vessel and testing lines, etc. The open/close pressure is controlled by spring washer. When the pressure exceeds preset limit, the valve may automatically unload. When the pressure drops below preset limit, the valve may automatically close to protect people and equipment. Jereh Safety Valves feature high strength, wide pressure range and stable performance. Jereh Safety Valves are forged from premium alloy steel, handled by advanced metal melting and heat treatment technology. Different number combination of spring washers allows wider pressure adjustment range. Pressure relief device realizes stable seal. To meet various demand, Jereh has developed many types suitable for cementing, acidizing, fracturing and testing lines. Customized service is also available.

Jereh swivel joints are forged from premium alloy steel, handled with advanced metal melting and heat treatment technology to ensure strength and hardness. Based on analysis of weight, resistance to abrasion and blasting, Jereh developed optimum wall thickness for swivel joints, introduced advanced equipment and machining technology to ensure the uniformity of wall thickness, the longest service life and highest safety factor with the weight unchanged. Special seal design and seal material significantly increase sealing capability and service life.
