Pneumatic Tyre Union/ Air-o-unions
Pneumatic tyre union is widely used in those pipelines, like low-pressure, large pipe size, big pipe misalignment, frequent installation and uninstall. Especially, in connecting mud tanks, mud suction and return lines in solid control system.
Fast, easy make-up without close alignment
Allows pipe expansion or misalignment without breaking the seal
No nuts, bolts, or wrenches required
Available in 4-, 6-, 8-, 10-, 12-, 14-inch sizes
1. Working medium: mud,oil,water
2. Medium temperature:-45~50 C
3. Reconversion time when deflated: 1-3 seconds.
4. Medium presssure:0.4Mpa
5. Structure: steel shell and pneumatic tyre
Mud tank unions
Mud tank union is an updated based on pneumatic unions. Tank unions can accept pipe misalignment to finish an excellent connecting and sealing, and installation and uninstall rapidly, which has been widely used in mud tanks, mud tank connecting lines, and pump suction flanges.
Molded nitrile seal provides a compression seal
Makes up with hammer
Elongated cross-section of seal ring ensures greater sealing surfacewhen in contact with the pipe
Tank union accepts up to 7 deg. pipe misalignment
Available in 4,6, 8,10,and 12inch sizes
6, 8, 10inch unions may be socket welded to pipe, or butt welded to tubing.12inch unions require butt-weld.
With large diameter, medinm-low voltage and frequently dismantling, rapid installation and dismantling.
1. Working medium:mud,oil,water
2. Medium temperature:0~90 C
3. Ambient temperature:-30~50 C
4. Medium presssure:0.6Mpa
Wing union/Hammer Union
Hammer unions are widely used in manifolds, line connections, pump suction, pump services, Cementing, and choke-and kill lines. Series of hammer unions are made of different material to suit different pressure, environment request. From 1,000 psi to 20,000 psi in generial service or corrosion service, including Fig100,FIG20
