Frequently Asked Questions
What is the difference between a Test Ball and a Muni Ball?
- A Test Ball does not have a bypass and is only intended to block (seal) a pipe.
- A Muni Ball has a bypass tube that runs through the plug, allowing the user to bypass effluent through the tube or complete an air test with an adapter cap.
- Muni Balls can also be used to obstruct pipes.
How to install Cherne Test-Ball plugs?
- Place the plug in the pipe or application to be blocked or tested, making sure it is at least as long as the pipe diameter.
- Connect one end of the inflation hose to a plug inflation fitting (such as a Schrader valve, 1/4, 3/8 / 1/2-inch port). The other end of the inflation hose is connected to line pressure, a pump or another source of pressure.
- Connect a second hose to the fitting if another one is available. The other end of the second hose should be connected to a gauge that has been calibrated.
- Before inflating the plug, use the appropriate method to block / brace it.
- Apply pressure to the plug using the inflation hose. Fill the plug to the inflation pressure specified on the plug.
- Allow the plug to settle for a few moments. If necessary, add pressure to maintain the rated inflation pressure.
- Continue testing the pipe / application. Once done, release back pressure behind the plug outside the danger zone.
- After releasing back pressure, relieve plug pressure from outside the danger zone until the plug is completely deflated.
- Take down the blocking / bracing system. Finally, take the plug out of the pipe.
What is the maximum temperature that these plugs can handle?
They can handle temperatures ranging from 0 to 125 degrees Fahrenheit.
