Product Description


Ordinary Medium Pressure Union Classification:

300 Cold Working Pressure (3,000 psi/207 bar) , under medium pressure, Standard Environmental Economy , General Purpose of connection economy between manifold and pipeline

400 Cold Working Pressure (4,000 psi/276 bar) , under medium pressure, Standard Environmental Economy , General Purpose of connection economy between manifold and pipeline




High-Middle-Low Pressure Union


1. Figure 602


With resilient nitrile-butadiene rubber seal ring, this figure is used for sealing and protecting the steel-to-steel match.


It is recommended for the connection of manifold and pipe and truck-mounted application and mud delivery. It may be used as pressureless seal union with butt weld Sch. 80.


2. Figure 1002


Resilient nitrile-butadience rubber seal ring is mounted.


It is recommended for cement filling, fracturing, acidizing, testing and chock and kill line. It is designed for high-pressure systems including truck-mounted system. Also, it may be used as pressureless seal union. Butt weld Sch. 160 or XXH is desired.


3. Figure 1003


With an spheric seat, the union allows a deviation by 7-1/2° from the center or angle adjustment with a total deviation capacity of 15°. In addition to the steel-to-steel match, the nitrile-butadience rubber O-ring ensures air-tightness in connection at any deflected position.


It is recommended for the connection of high-pressure lines when alignment is impossible. The product may be used in applications with air, water, oil, mud or gas.


4. Figure 1502


With replaceable resilient nitrile-butadience rubber seal ring and robust wall thickness design, this figure is used in high-pressure system.


It is recommended for cement filling, fracturing, acidizing, testing and chock and kill line. Also, it may be used in pressureless seal connection. Butt weld Sch. XXH is desired.


5. Figure 2002


For this union, only the 2 in type is available with a replaceable resilient nitrile-butadiene rubber seal ring combined in the stainless steel liner tube, providing complete compression protection in application with extra high pressure. The design of detachable nut/segment ring/retainer ring simplifies the removal of the nut from the piping.



6. Main Technical Parameter of American 1502 High-Pressure

Union and GJ series Union


7. Figure 2202


With fluoroelastomer seal ring, 15000PSI NSCWP and the heat-treated parts 100% subjected to hardness test, this model complies with National Association of Corrosion Engineers Standard MR-01-75 and American Petroleum Institute RP-14E.


This product is designed for application with acid gases. Green nuts and parts.
