MTDPOLYSTOP™

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.
