Based on years of experience and research on customer needs in the oil/gas industry, Jereh has successfully developed treating iron products suitable for both standard, low-temperature and sour services, including swivel joint, plug valve, integral pup joint, integral fitting, safety valve, check valve, choke valve, hose loop and reel swivel. Maximum pressure is up to 20,000psi. Each treating iron product is conducted strict quality control and test, meeting international standards including ASTM/ASME. Each product has the only traceable number for lifecycle quality management. Tool kit and repair kit are available to suit each product for easy maintenance. Besides standard products, we can also provide customized service to meet various customer needs.

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.

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.

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.
