Corrosion Under Pipe Supports (CUPS) is a persistent, expensive problem in industrial piping. It develops in the narrow band where the pipe rests on its support, a tight gap that traps moisture, salts, and debris while vibration and thermal movement bruise coatings. Small coating defects in that zone can turn into hidden corrosion cells that drive leaks, unplanned outages, and safety or environmental incidents.
The RedLineIPS SmartPad System, developed by Cogbill Construction in Texas, is a fully non-metallic, weldless, epoxiless pipe support solution created specifically to break that cycle. A contoured FRP saddle, bonded closed-cell Hydroseal gasket, composite SmartBands, and a simple SmartTool work together to form a sealed, dielectric, vibration-damping, and reopenable interface at each support—installed as cold work on live lines in minutes, and reopened just as quickly for direct visual inspection.
The benefits of this approach can be grouped and summarized as follows:
1. General SmartPad System Benefits
(Any facility with steel piping: refineries, chemical plants, terminals, power stations, offshore platforms, FPSOs, coastal plants, etc.)
1.1 Core Corrosion Protection at the Pipe/Support Interface
- Watertight, sealed interface (NEMA-4–like when compressed)
Closed-cell gasket seals the pipe/pad contact, keeping brine, rain, washdown water, and condensate out of the crevice. - Eliminates metal-to-metal contact
FRP saddle + gasket + composite bands create a fully non-metallic load path, breaking galvanic and differential-aeration cells. - Exact NPS match – no voids
Pads are built to the pipe OD, avoiding “daylight” gaps that act as crevices. - Works on scarred/repaired pipes
Gasket compresses around pits, weld caps, and spot repairs, maintaining a seal on imperfect surfaces. - Elevation and airflow
Lifts pipe off steel, improving drying at the support and further reducing crevice and under-deposit corrosion.
- Watertight, sealed interface (NEMA-4–like when compressed)
1.2 Structural Performance, Mechanics & Coating Protection
- Heavy-duty, all-composite FRP exoskeleton
Purpose-built saddles carry significant compressive load with long service life in industrial and marine environments. - High structural resiliency
Maintains shape and support under load, unlike softer plastic rods or liners that crush or creep. - Contoured saddle – no point/line loading
Cradles the pipe and spreads bearing stress, protecting coatings and reducing local stress peaks. - Recessed band grooves & sloped edges
Grooves lock bands in place; sloped edges help the pad and pipe recenter after movement. - Vibration and noise damping
Gasket layer reduces fretting at the contact and lowers structure-borne noise.
- Heavy-duty, all-composite FRP exoskeleton
1.3 Materials, Temperature, UV & Chemical Performance
- Wide operating temperature range
Typical assemblies handle about −60 °F to 400 °F (−51 °C to 204 °C), depending on gasket selection. - Low flammability/fire-retardant FRP
Fire-retardant resin systems support use in high-hazard facilities. - UV-stable, long-life materials
FRP and gasket options resist UV, chalking, and embrittlement for outdoor and offshore duty. - Broad chemical compatibility (gasket options)
EPDM, silicone, PTFE-faced and other options cover aggressive chemicals, hydrocarbons, and utilities. - Proven, non-exotic materials
Uses FRP laminates, elastomeric gaskets, and composite bands with decades of field history; the innovation is in the integration, not new chemistry.
- Wide operating temperature range
1.4 Installation, Inspection & Operational Efficiency
- Epoxy-less and weld-less system
No mixing, no cure windows, no weld prep, no hot work at supports. - Install on live lines (no shutdown in most cases)
Cold-work installation fits retrofit campaigns without process outages. - Very fast installation and removal
Typical install in seconds to a few minutes versus tens of minutes plus cure time for epoxied and welded options. - Minimal training; low error risk
Simple, repeatable steps reduce installer dependence and cut the chance of bad installs. - Preset SmartTool tensioning
Controlled band load gives repeatable compression and seal quality across crews and shifts. - Visual inspection in seconds
Cut bands, lift pad, wipe and inspect, re-band; many CUPS checks become quick visuals instead of heavy NDT.
- Epoxy-less and weld-less system
1.5 Safety, Permits & HSE
- No welding / grinding at supports
Removes hot-work risks and simplifies permits. - No epoxy mixing or solvents
Avoids VOCs, pot life issues, cold-weather unworkability, and cure-related failures. - Shorter tasks at height / fewer confined-space NDT jobs
Faster installs and inspections reduce exposure hours and HSE risk. - Cleaner workface
No weld spatter, drilled holes, or adhesive cleanup; fewer paint repairs.
- No welding / grinding at supports
1.6 Design, Flexibility & Standardization
- Accommodates any pipe size (exact NPS)
Custom pads for size, schedule, and coverage angle allow standardization across a facility. - Retrofit-friendly
Drops into existing supports with no new steel penetrations; ideal for prioritized upgrades by risk. - Newbuild-ready
Can be written into design standards so new assets start with sealed, dielectric contacts. - Works across onshore, coastal, offshore & FPSO assets
One support philosophy across multiple asset types simplifies spares and procedures. - CP/earthing compatibility
Isolation can be checked quickly; easy to align with site CP/earthing strategies.
- Accommodates any pipe size (exact NPS)
1.7 Lifecycle, TCO & “Maintenance-Free” Performance
- Lower installed cost per support
Quick cold-work installs, no welders, no cure time, fewer permits → lower installed cost than welded, drilled, and epoxied options. - No planned shutdown for most retrofits
Avoids production losses commonly tied to welded modifications. - Lower inspection cost
Supports can be opened visually in minutes, reducing reliance on expensive UT/EMAT/RT at every CUPS location. - Minimal ongoing support maintenance
Non-metallic, UV-stable components avoid rusting, repaint cycles, and re-torquing. - Reusable components
Saddles, gaskets, and buckles can be reused on same-size lines; band stock is the main consumable. - Multi-year OPEX and risk reduction
Lower leak probability, fewer emergency repairs, reduced downtime, and better RBI execution drive total cost of ownership down over the life of the asset.
- Lower installed cost per support
2. Offshore Platform–Specific Benefits
(Fixed jackets, gravity-based structures, coastal plants with marine exposure)
2.1 Built for Harsh Marine Exposure
- Marine-grade corrosion resistance
Handles salt spray, humidity, rain, washdowns, and firewater test wetting in topside environments. - UV-stable on open decks
Long-term performance under direct sun and weather on windward faces. - Sealed interface in splash / washdown paths
Maintains dryness at supports even in regular firewater testing and hose-down zones.
- Marine-grade corrosion resistance
2.2 Pipe Rack Integrity, Vibration & Coating Life
- Coating protection in congested racks
Contoured saddle and radiused contact reduce damage where recoating is difficult. - Anti-walk behavior under deck vibration
Grooved bands and durable preload resist strap migration from pumps, compressors, cranes, and wave-induced motion.
- Coating protection in congested racks
2.3 Offshore Work Execution, Safety & OPEX
- No welding or epoxy at height
Reduces hazardous work and the number of hot-work and special permits required in pipe racks. - Shorter offshore work packs
Minutes per support mean more upgrades per trip, better use of vessel/helicopter time. - Reduced NDT burden at supports
Visual inspections replace many complex CUPS NDT jobs, lowering cost and exposure hours. - Field-proven with major operators
Deployed on offshore and coastal platforms with multi-year performance history.
- No welding or epoxy at height
3. FPSO-Specific Benefits
(Floating Production, Storage & Offloading units)
3.1 Managing Motion, Wetting & CUPS on Floating Hulls
- Stable seal under heave, roll & pitch
Gasket compression and saddle geometry keep the interface sealed as hull and pipe move. - Ideal for sweating cold lines and “always-wet” decks
Closed-cell, non-wicking gasket suits chilled and condensing services. - Dielectric separation under dynamic motion
All-composite load path prevents metal contact from re-forming under flexing supports.
- Stable seal under heave, roll & pitch
3.2 Vibration, Noise & Mechanical Integrity on FPSOs
- Load distribution under combined motion
Saddles spread stress where hull flex, wave loading, and thermal growth interact. - Anti-walk grooves for continuous low-level motion
Bands stay locked in place across roll/pitch cycles, preserving clamp force and seal. - Vibration and noise damping on ship-shaped hulls
Gasket reduces rattles and structure-borne noise, helping both integrity and crew comfort.
- Load distribution under combined motion
3.3 FPSO Operations, Safety & Lifecycle Economics
- No hot work on moving decks
Cold-work installs simplify SIMOPS and reduce fire risk. - High-impact OPEX savings where labor is expensive
Very fast installs, simple training, no cure time, and no shutdown requirement strongly favor SmartPad in offshore maintenance economics. - Supports life-of-field and life extension
Fewer CUPS-driven leaks at supports help maintain uptime, support integrity cases, and improve the asset’s long-term cost and risk profile.
- No hot work on moving decks
