MTDPOLYSTOP™ Plugging Machines
Plugging Machines for HDPE Pipe
The MTDPOLYSTOP™ System is designed to stop flow through an in-service section of 4”, 6”. 8” or 12” polyethylene pipe up to 125 psi.
- Designed to be lightweight, which saves operator fatigue and eliminates harmful stresses on HDPE pipe.
- Familiar folding-head operation.
- SDR-specific sealing elements for the best sealing performance.
Permanent Relocation of Existing Mainlines
The MTDPOLYSTOP™ plugging machine is ideal for stopping flow through an existing mainline for abandonment after a permanent relocation line has been installed.
M.T. Deason also offers size-on-size electrofusion hot tapping valves & branch saddles through 8"× 8" IPS for this purpose.
Permanent Repair following an Emergency Squeeze
MTDPOLYSTOP™ is also commonly used for replacing a section of pipe that has been squeezed in an emergency.
The temporary bypass ports on the housings of both plugging machines allow service to remain uninterrupted downstream of the section being replaced.
The MTDPOLYSTOP™ System is now available in convenient kits by size. Each kit includes all the equipment needed to perform a double-position stop operation:
All kit items are packed in an aluminum case with custom-cut supporting foam so everything has its place.
These double-position kits are perfect for short-notice jobs, or just to keep everything organized.
Each MTDPOLYSTOP™ machine includes:
