Pop-A-Plug® CPI/Perma Tube Plugs

 

Perform Maintenance on Leaking Condenser & Boiler Tubes

Choosing the wrong plug for your heat exchanger tube leaks can increase downtime and further damage equipment.

EST Group’s Pop-A-Plug Tube Plugs are a permanent mechanical tube plugging solution for leaking heat exchanger, condenser, and boiler tubes. Mechanical tube plugs feature an internally and externally serrated ring designed to maintain a helium leak-tight seal even under extreme thermal and pressure cycling.

Pop-A-Plug Tube Plugs install hydraulically in minutes with an engineered breakaway while offering a controlled installation force to limit operator fatigue and prevent damage to tubes, tubesheets, and surrounding tubes.

Choose from a broad range of tube sizes and materials. Full material traceability documentation available.

Pressure Rating Up to 1,000 PsiG (68.9 BarG) - higher pressures available upon request

Size Range 0.472” to 2.067” (11.99mm to 52.5mm) Tube I.D. -larger/smaller sizes available upon request View Size Chart

Standard Material Brass 360/464, Carbon Steel (1018 & 1045), 304/304L Stainless Steel, Copper Nickel 70/30, 316/316L Stainless Steel, Titanium – additional alloys available, contact customer service for full list

Features & Benefits

  • Plug material matches tube material preventing thermal expansion and contraction issues and/or undesirable galvanic interaction
  • Resistant to thermal and pressure cycling
  • Eliminates welded or explosive plugging methods
  • Meets ASME PCC-2* recommendations and EPRI** criteria
  • Lowest lifecycle cost compared to alternative plugging methods
  • Maintains helium leak-tight seal to 1 x 10-6 cc/sec

320 Series

320 Series

320 AxFlo Trim is a high resistance, multi-stage, axial flow path trim to combat erosive service.

  • 2 to 8 inch NPS (50 to 200mm DN)
  • Globe Body Style
  • RF |  RTJ  |  NPT  |  BWE  |  SWE Available End Connections
  • ASME B16.34 Class 300 / 600 / 900 / 1500 Pressure Rating
  • ANSI/FCI 70.2 and IEC 60534-4 Class V Shutoff

More Details

320 AxFlo Anti-Cavitation trim is a heavy duty dirty service trim option designed for entrained particulate and high pressure drop applications. AxFlo trim offers multi-stage protection against cavitation and erosion.

You can expect enhanced trim life when using AxFlo trim because pressure gets distributed over the length of the valve plug across multiple STAGES. Each STAGE is not exposed to the full pressure differential, and on properly sized 320 valves, the amount of pressure drop per STAGE is controlled to prevent cavitation.

Overview

 

320 Series

Principles of Operation

Dyna-Flo 320 AxFlo trim is a high resistance, multi-stage, axial flow path trim, which means process fluid will flow through AxFlo valves parallel to the axis of the plug and cage.
This design is well suited to reduce clogged flow passages in applications involving fluids with entrained particles.

You can expect enhanced trim life when using AxFlo trim because pressure gets distributed over the length of the valve plug across multiple Stages, this means each Stage is not exposed to the full pressure differential. On properly sized 320 valves, the amount of pressure drop per Stage is controlled to prevent cavitation problems and to minimize erosion issues.

LINEAR - ANTI-CAVITATION FLOW UP 

AxFlo trim is designed to have no significant flow for the first 15% of travel, this design feature is in place to maximize the life of the seat ring.

The multi-stage clearance flow design helps prevent high pressure drops in the seating area during throttling at low capacity. By preventing these high pressure drops, we can significantly extend the shutoff capability while simultaneously enhancing the throttling control at low travels.
