Hammer Union Fig400
Recommended working media: Air, Water, Oil, Gas and Mud. The pressure between the metal and the metal is sealed by virtue of the close coordination of the precise spherical end and conical surface. While the size exceeds 4 inches, the seal of the hammer union assembly is replaced by O-type seal ring.
Hammer Union type mainly consists of Figure50, Figure100, Figure200, Figure206, Figure207, Figure400, Figure600, Figure602, Figure1002, Figure1002 ,Figure1502, Figure2002 etc.
For the pressure seal pipe thread, it is not recommended to use under the surge pressure with above 70 MPa, or the side loading, or the working environment with estimating the corrosion. The non-pressure seal thread or the straight integral connections will be better under the above-mentioned conditions. In order to acheive the recommended vibration free cold working pressure, the threading connection needs the power firm device. Other usage under the abnormal working state can be consulted with the plant.
