2.3 MDS Inflatable Stopper Specifications
2.3 MDS Inflatable Stopper Specifications
A)
MDS Stopper size = 1.96” – 2.16” (50 mm – 55 mm) [Part #23000096]
B) Inflation pressure = 2x system pressure and/or 22 psi maximum
NOTE: If the condition of the interior of the pipe being stopped is unknown, it is a recommended practice to
inflate the stopper to the maximum inflation pressure to obtain the best stop off possible.
C) Design burst pressure = 170 psi
D) Operating temperature range = 5° F (- 15° C) to 140° F (60° C)
E) Maximum temperature range = 158° F (70° C) for up to 30 minutes
2.4 Hand Pump (Pressure and Vacuum Pump)
2.4 Hand Pump (Pressure and Vacuum Pump)
A)
1 positive pressure connection
B) 1 negative pressure (vacuum) connection
C) 10 foot air hose with quick disconnects included
D) Weight = 12 lbs.
2.7 Maximum Flow Rates
2.7 Maximum Flow Rates
A)
Maximum design flow rate = 65 ft/sec (19.8 m/sec)
NOTE: The system is designed to be used in controlled stop off applications, and is not intended to be used to
stop flows in severely ruptured pipes. Flow should be reduced before attempting stop off.
3.0 Typical Site Set Up and Sequence:
It is important to understand the MCS stopping tools and their operation completely. It is also important to understand the
complete job and sequence of steps to perform a safe stop. Safety of the operators on the job site is the most important
factor so pre-plan the whole job including the stopping and retrieval sequences.
The following examples are typical installations. Example I (green background) illustrates stoppers positioned towards
each other. Example II (blue background) illustrates stoppers positioned away from the work area. Both configurations
work equally well. For additional set up illustrations, see Appendix B or contact your distributor / MCS representative.
Remember to consider the ancillary steps like purging / venting the area to be worked on and back pressuring stoppers for
removal. The features of the MCS7-2PVC offer options to make these processes efficient.
