Hyspan Barco Ball Joints
Installation and Maintenance Procedures
Standard Series & 600 Series Ball Joints
Installation Recommendations
|
1.
|
|
The media flow direction can be from either end of the ball joint except for liquids with suspended solids, then flow should be from ball end to casing end.
|
|
|
2.
|
|
In vertical installations, ball joints should be installed with the ball end down to prevent foreign matter from collecting between neck of ball and retainer.
|
|
|
3.
|
|
Do not loosen the ball joint retainer during installation, or utilize ball joints as Unions. Each joint is factory preset and tested before shipment. LOOSENING OF THE BALL JOINT RETAINER IS NOT RECOMMENDED. If the retainer must be loosened it should be loosened 1/4 of a revolution maximum, and retightened an equal amount before any pressure testing or flushing of the line. There is a setscrew to maintain the position of the retainer - be sure the setscrew is loosened and retightened after the adjustment and prior to applying pressure.
|
|
|
4.
|
|
Use CAUTION PREHEATING, WELDING, OR POST WELD HEAT-TREATING ball joints into the line. Excessive heating of the sealing area may cause leakage.
|
|
|
5.
|
|
Protect the exposed ball surface from weld splatter, and prevent dirt and debris from collecting around neck of the ball.
|
|
|
6.
|
|
Although ball joints can be rotated or twisted around the centerline, they are designed to absorb motion by the Offset Method that utilizes angular flex to provide the required movement. Consult a Hyspan Barco sales representative or contact Hyspan by email at websales@hyspan.com if an application involves extensive rotating motion.

|
General Warning
Standard Series and 600 Series Hyspan Barco Ball Joints are not designed for maintenance to be performed while the system is pressurized. DO NOT PERFORM ANY ADJUSTMENTS TO A BALL JOINT THAT IS PRESSURIZED.
Maintenance Instructions
To correct leaks or to perform routine maintenance:
|
1. |
|
Relieve the internal pressure. |
|
2. |
|
Loosen the retainer setscrew and tighten retainer until it is snug against the ball using
a reasonable amount of torque with manual wrenches. Tighten the setscrew and pressurize the system. If leakage still occurs the ball joint can be disassembled for maintenance
|
|
3.
|
|
TO DISASSEMBLE the ball joint for maintenance it must be removed from the system.
|
|
a.
|
|
Disassemble by loosening the setscrew and removing the retainer.
|
|
b.
|
|
Inspect the inner seal for wear: The inner seal is seldom worn enough to require replacement. It is recommended that the outer seal should be replaced.
|
|
c.
|
|
Clean and inspect ball surface carefully. Replace the ball if it is worn, scored or pitted.
|
|
d.
|
|
Replacement balls and seals are available from an authorized Hyspan Barco representative or by contacting Hyspan by email at websales@hyspan.com. Be certain to dispose of the discarded seals properly.
|
|
e.
|
|
To reassemble, coat the surfaces of seal(s) and ball with a light coat of assembly lubricant. For service over 350º F use molybdenum disulfide based lubricant.
|
|
f.
|
|
If the inner seal has been removed, install it in the case with the concave surface
out by tapping it in place evenly with a soft mallet.
|
|
g.
|
|
Slide new outer seal over extended end of ball with the concave surface mating to
the convex surface of ball.
|
|
h.
|
|
Replace ball into case.
|
|
i.
|
|
Tap the new outer seal evenly with soft mallet into casing around ball.
|
|
j. |
|
Add thread lubricant to retainer threads and replace the retainer - tighten until the seals are snug against the ball with a reasonable amount of torque with manual wrenches. Do not back off. Tighten the setscrew.
|
|
Note: In some sizes with 90º balls, it may be necessary to slip seal and retainer over the ball before seating ball and seal into case to provide clearance at neck or elbow.
