Packed ball joints provide an economical, safe, and reliable method of absorbing large amounts of single and multiple plane displacements including rotation. Ball joints are an ideal choice for systems with vertical pipe runs and/or natural offsets. Ball Joints are available in sizes ranging from 3/4″ to 30″ for service conditions of up to 1000 psig at 750°F. designed ball joints can accommodate 15° to 33° of angular flex and 360° of rotation.
Thermal Pak ball joints employ the latest technology and are designed to meet the requirements of the ASME Boiler and Pressure Vessel Code as well as the ASTM F1298 Specification covering packed ball type expansion joints.
Standard ball joints include such special features as:
- A high performance injectable packing which is suitable for operation at temperatures up to 1000°F.
- Packing cylinder designs that allow in service packing of the joint and uninterrupted process at pressures up to 1000 psig.
- Series P2 and S2 ball joints are designed using a patented integral socket/retainer design that eliminates the in-service field error of over tightening the flange bolting or retainer cap.
Ball joint systems provide cost savings advantages by providing for movement in two or more planes simultaneously, by allowing more movement in less space, and by reducing the number and size of system anchors.
