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.

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.

Integral pup joints are straight tubes with union connection on both ends, widely used for transporting high pressure flow in fracturing manifold, cementing manifold, servicing manifold and testing lines. Jereh integral pup joints are forged from premium alloy steel. Metal melting and heat treatment processes ensure the strength. Based on analysis of weight and erosion resistance, Jereh has improved wall thickness and inner bore, extending service life, making them the ideal choice for oilfield applications. To meet diverse customer needs, integral pup joints for standard service are available with many styles, pressure and temperature rating. Besides, Jereh has introduced integral pup joints for sour gas service as per NACE MR 0175. 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.
