Tube Plug Uses
Corrosion and wear eventually cause tube leaks. A tube plug seals off the bad tube so fluids can't cross between the tube and shell side, and the rest of the exchanger keeps working.
Snap It® Engineered Tube Plugs
Our weld-free Snap It® plugs install hydraulically in under 60 seconds. No hot work permits, no sparks, and no damage to the tubesheet. Snap It® Jr. is rated to 1,000 PSID and Snap It® Sr. to 7,000 PSID.
Puncture the Tube First
Always puncture the tube before installing any plug, so pressure can't build up behind it and loosen or blow out the plug. The One-Rev Internal Tube Cutter punctures a tube in a single revolution and works with the Snap It® system.
Heat Exchanger Tube Plug FAQ
What is a heat exchanger tube plug?
A plug inserted into a leaking or damaged tube to seal it off, so fluids can't cross between the tube side and shell side. The rest of the exchanger keeps running.
Which tube plug is right for my exchanger?
