Pipe supports are where corrosion prevention plans often become reality—or quietly fail. Corrosion under pipe supports (CUPS) is a “touchpoint” damage mechanism driven by water entrapment, crevices, and difficult access. In the field, the biggest challenge is that a support solution must work in two very different worlds: new construction (where everything is being built and assembled) and maintenance (where uptime, permits, access, and inspection cost control the schedule). Independent industry literature repeatedly highlights the same themes: water trapping at supports creates crevice conditions, and the damage is often hidden and costly to quantify without specialized inspection.
The SmartPad System was designed to bridge that gap—one interface that works on new pipe, in service, and even on previously treated pipe surfaces, while also making inspection simpler and cheaper over the life of the asset.
Greenfield vs. Brownfield
To avoid jargon confusion:
- New construction (greenfield): a new build where piping and structural steel are being fabricated and installed as part of a coordinated construction effort.
- Maintenance / retrofit (brownfield): modifications and repairs inside an operating facility where access is constrained, permits matter, and shutdowns or production delays can dominate cost and schedule.
CUPS in brief: why supports corrode even when coatings exist
CUPS typically starts because common support geometries create a tight contact zone that traps water and limits drying. Once moisture (often chloride-bearing in coastal/offshore service) is held against the pipe, corrosion can initiate and then spread under coatings as oxygen gradients and crevice chemistry develop. In these shielded areas, coatings don’t behave like they do on free pipe spans: water can wick through defects, along coating edges, or through microvoids, and the trapped electrolyte keeps the surface wet long enough for underfilm corrosion to grow.
At the same time, galvanic effects can amplify damage when metal-to-metal contact exists or when small coating holidays expose steel at the support interface. With a conductive path through the support and an electrolyte present, the local electrochemistry can concentrate attack at exposed spots—turning tiny defects into aggressive corrosion sites. This is one reason two supports that “look the same” can corrode at very different rates depending on contact condition, wetting frequency, and how well the coating remains intact at the interface.
A third contributor is mechanical wear and fretting: vibration and thermal cycling can microscopically rub the coating at the contact zone, creating or enlarging defects that then become the starting point for crevice and galvanic corrosion. In practice, these mechanisms are coupled—abrasion opens the coating, water retention sustains the electrolyte, crevice chemistry accelerates the localized attack, and galvanic coupling can intensify it.
Inspection is the second practical problem: the most relevant area is often hidden and hard to verify using conventional methods. Full line lifting or disassembly can be impractical on live systems, and in high pipe racks the equipment, access, and coordination required for advanced NDE (UT mapping, guided wave, radiography) can be expensive and time-consuming. That’s why designing for inspectability matters: SmartPads support a simple workflow where the interface can be opened by releasing the banding and removing the pad, the pipe can be checked with minimal clearance at the support, and the assembly can be re-secured—reducing reliance on logistically heavy, high-cost inspection deployments.
What the SmartPad System is
The SmartPad System, from Cogbill Construction, is a non-metallic support interface built around:
- a contoured FRP saddle (load spreading + dielectric separation),
- a bonded closed-cell gasket intended to seal and conform at the pipe–pad interface, and
- composite bands and buckles that apply consistent preload and can be easily removed/reinstalled quickly for inspection.
How SmartPads work
SmartPads win on a combination of simple, field-relevant mechanisms:
- Sealing and water exclusion: A compressive, closed-cell gasket is used to eliminate the pathways for moisture and contaminants to enter and remain at the touchpoint. This directly targets the “water trapping + crevice” conditions that drive CUPS.
- Dielectric break (no metal-to-metal path): By introducing a non-metallic load path between the pipe and structural steel, the system eliminates metal-to-metal contact at the support interface—important in mixed-metal environments and in wet service.
- Load distribution to protect coatings: A contoured saddle spreads load and avoids point/line loading, reducing localized coating stress and wear that otherwise becomes an initiation point for corrosion. This aligns with broader industry observations that common support types create crevices and inspection obstacles and are implicated in a large share of external piping corrosion failures.
- Vibration and micro-movement control: Micro-movement at supports can abrade coatings and “pump” moisture/contaminants in and out. SmartPad materials and gasket behavior are positioned to damp vibration/noise and reduce that micro-motion.
Suitability for new construction (greenfield)
In a greenfield project, welding and hot work are already part of the construction workflow, so the practical advantages are:
- Speed and consistency at scale: SmartPad materials are installed mechanically, with no welding or drilling, no epoxy mixing, no cure time, and no touch-up cycles built into the work package. This is why installation time is around two (2) minutes per SmartPad.
- Lower dependence on installer experience and skillset: Adhesive bonding is highly sensitive to surface condition and prep. Even in controlled environments, epoxy bonding generally demands clean, dry, properly prepared surfaces and good wetting/contact; contamination and inadequate surface prep are well-known failure contributors. Also, without the need for welding to install the SmartPads, costly skilled welders are no longer required to protect piping. On large projects, reducing workmanship variability and cost are often as valuable as reducing minutes-per-support.
- Sets you up for future reliability work: The “construction choice” becomes tomorrow’s maintenance constraint. Selecting an interface that can be reopened and resecured later changes inspection strategy and future work planning, and drastically reduces the total cost of ownership (TCO).
Suitability for maintenance projects (brownfield)
- Minimal lift and practical access: In many retrofit situations, the line only needs a small lift to insert the SmartPad (~¾ inch). That matters because brownfield work is limited by access and congestion: if you can avoid large crane picks and heavy rigging, you remove a major planning and schedule variable.
- No welding/cutting/drilling: In operating facilities, “no welding” is not just convenience—it can be the difference between a routine maintenance job and a delayed scope waiting on permits, gas testing, fire watch staffing, and the operational coordination that comes with hot work. And “no cutting/drilling” also reduces the chance that a seemingly simple support change triggers additional structural modifications or line constraints.
- Works on previously treated and uneven surfaces: Epoxied FRP wear pads generally require surface prep and smoothness for reliable adhesion. Surface prep guidance for epoxy bonding consistently emphasizes cleaning/degreasing, drying, and roughening/conditioning to maximize bond area and wetting; contamination or moisture films can significantly weaken the bond.
In a brownfield unit, the pipe surface is rarely “ideal”—it may have prior corrosion treatment, touch-up paint edges, profile irregularities, or residual films.SmartPads are specifically positioned as suitable for new, existing, and treated pipes because the closed-cell gasket conforms under compression rather than depending on adhesive bond strength to a prepared substrate. This single point is what makes one product truly viable for maintenance projects.
Why one solution across the lifecycle matters
Standardizing one support interface is not just an inventory preference—it’s a reliability strategy:
- Specs and details stay consistent: one design basis through build-out, tie-ins, and future revamps.
- Inspection planning becomes repeatable: the same “open/inspect/resecure” logic can be embedded into route-based inspection, turnaround scopes, and mechanical integrity programs.
- Training burden drops: fewer “special-case” installations that require niche craftsmanship.
- Spare parts simplify: instead of replacing an entire bonded pad or dealing with welded components, the system is designed so the “consumable” portion is primarily banding/straps, while core components remain in service.
These are the quiet benefits that pay off year after year: fewer unique procedures, fewer surprises, fewer re-learning cycles.
Conclusion
If the goal is to reduce CUPS risk and reduce the time and cost of living with CUPS over decades, the support interface must be suitable for both new construction and maintenance. The SmartPad System is positioned to do that by combining a non-metallic load-spreading saddle with a closed-cell conforming seal and fast mechanical banding—avoiding the prep sensitivity and cure-time logistics that make epoxy-bonded pads difficult in real brownfield conditions.
The result is a single, standardized approach: fast to install in construction, fast to retrofit in maintenance, and designed to make future inspection cycles cheaper and easier by allowing quick open-and-resecure checks rather than turning every support into an NDE planning event.
