Reel swivels are mainly used in coiled tubing units with one end connected to the coiled tubing and the other end connected to surface manifold to rotate under pressure. Jereh reel swivels feature excellent sealing capability and strong corrosion resistance. Special sealing configuration and components ensure higher sealing performance and longer service life. Key seal surfaces are treated specially to enhance corrosion resistance. To meet diverse needs, Jereh offers two basic types (U-shape and L-shape) both for standard and sour gas service. Customized design is also available.

Hose loops are used to transport fluids for a variety of high pressure well service applications including discharge lines, well test lines and cementing lines. Jereh hose loops include long radius type and integral flexible type. Long radius hose loops combine advantages of Jereh long radius swivel joints and integral pup joints, featuring erosion, vibration and shock resistance, and large flow. Integral flexible hose loops feature single union connection with excellent sealing and rotary performance. It is an ideal product for oilfield operation. Jereh offers hose loops both for standard and sour gas services, suitable for cementing, fracturing, acidizing and testing lines. Customized design is available to meet diverse needs.

Integral fittings are mainly used to connect components to form surface manifolds. Forged from high strength alloy steel, Jereh integral fittings have gone through advanced heat treatment and strict quality control before delivery. Jereh integral fittings adopt union or thread connection. Jereh integral fittings are available in many types such as tees, laterals, wyes, long radius elbows, elbows, crosses, adapters and plug unions. Customized design is also available.

Choke valves are widely used to adjust pressure and flow. Jereh choke valves include the hydraulic and manual in respect of the operation mode. Adjustable choke valves adopt union connection and the orifice size is adjusted to achieve the regulation of flow and pressure.

Check valves are widely used in high pressure pipeline to control fluids flowing in one way and stop fluids from flowing back to the pump, protecting pipeline safety. Jereh check valves are available in three types including top-entry, dart and flapper. The top entry and flapper types adopt completely wrapped flappers to extend the service life, and they are mainly used in fluid services. Dart check valves feature dual seals between stainless steel and seal ring and they are mainly used in gas services.

Pressure relief valves act as a fail-safe for reciprocating plunger pumps, pressure vessels and testing lines, etc. The open/close pressure is controlled by belleville washers. When the pressure exceeds the preset limit, the valve will release pressure automatically. When the pressure drops below the preset limit, the valve will close automatically to protect the personal and equipment safety. Jereh pressure relief valves feature high strength, wide pressure range and stable performance. The pressure containing parts are forged from premium alloy steel and the metal melting and heat treatment process guarantee the hardness and strength. Various belleville washer stack configurations are available for different pressure ranges. The special treatment of the pressure relief mechanism provides stable sealing performance. To meet diverse customer needs, Jereh offers pressure relief valves suitable for cementing, acidizing, fracturing and testing lines. Customized design is also available.
