Mechanical pipe plugs for pipeline testing and isolation
Justram BTT-145 mechanical pipe plugs provide a bolt-tightened seal for pipeline isolation during testing and construction. Replaceable seals support ongoing service, with body and seal options to suit the application.
Construction and options
- Standard construction: aluminum body, steel hardware and solid nitrile seal.
- Options include EPDM or Viton seals, steel or stainless steel body and hardware, and solid or inflatable seals.
- Contact Justram about other sizes, pressures and non-circular openings.
Applications
Water and force mains, lift stations, fire protection lines, irrigation supply lines and plant piping.
Pressure ratings and selection
Listed models are rated at 100 psi (6.89 bar) or 200 psi (13.8 bar), depending on size. These ratings apply to steel pipe only. Other pipe materials require lower ratings or additional restraints. Confirm the selected plug rating and follow installation instructions.
The listed sizes span pipe openings from 1.9" to 24.875"; availability is not continuous. Select by the actual pipe inside diameter and the individual minimum and maximum dimensions below.
