128 Series Line Stop Plug WARNING Read and understand before using Petersen Line Stop Plugs! Failure to comply may result in property damage, serious injury or death! These instructions must be available to all users. Train all personnel for proper use.
Use two accurately calibrated pressure gauges that agree to monitor the inflation pressure. Verify that the pipeline flow is stopped. Contact the project engineer or Petersen if needed. Safety is the highest priority. Petersen Products 128 Series Important Safety Instructions 1...
Petersen recommends inspecting the line stop plugs after every use. Covers can be damaged when inserting into a hot tap. Often line stop plugs can be refurbished and recertified by Petersen Products to like-new condition or set interval to match quality standards.

Maximum vertical lift from the pipe invert is 18 ft. The Pump will only lift 18 ft on the inlet side. Pipeline pressure can assist with water deflation. If needed, Petersen can make line stop plugs that displace water with air for lifts over 18 ft.
After one section of the Inflation Ram is retracted, attach a Stop Collar at the lower Ram section to prevent the Ram from falling back down into the pipe. Remove the Inflation Ram one section at a time. Move the Pull Block down each time. Petersen Products 128 Series Removing the Line Stop Plug 29...
