Low Pressure Pipe Plugs

Low Pressure Pipe Plugs available in sizes to 240" ( 20' ) and to pressures of 15 Psig (1 bar)

Low pressure pipe plugs are used for the isolation of piping systems during testing, repair and maintenance, low pressure pipe plugs can be used for bypassing damaged sections of piping and for the testing of piping systems during construction. These Low pressure plugs can be used to verify the leak tightness of piping systems prior to putting the piping system into service. They are also used to individually test the integrity of pipe connections ie, welds, couplings, mechanical joints, gaskets.

Our pipe plugs provide positive "seal" against pipeline test pressures and positive "hold" (restraint) against total pipe pressure force.

Some additional applications are:
Dam penstock plugging
Plugs for blocking flows in culverts
Testing of manufactured parts
Night caps for newly installed piping
Debris dams for clean work
Men work platforms in vertical piping
FME (Foreign material exclusion)

Materials of construction of the pipe plug body are typically "light weight" corrosion resistant aluminum. If your requirements need another material we can provide:
Stainless Steel
Carbon Steel
Cast iron
Other materials available,... just ask!

Material of construction for the seals (elastomers) can be any of the following:
EPDM - Ethylene Propylene
Neoprene Chloroprene
Buna-N Nitrile
Natural rubber
SBR - Butadiene Styrene
Viton® Fluorinated Hydrocarbon
High temperature seals
