Honeywell Enraf Tape Wiper Assembly

Honeywell Enraf Tape Wiper Assembly for HERMetic UTI Tape (GTEx / RTEx)

The Honeywell Enraf Tape Wiper Assembly is an essential maintenance component engineered for the HERMetic UTImeter GTex (Gas-Tight) and RTex (Restricted) portable electronic gauging units. Designed for operation on crude oil, product, and chemical tankers, the tape wiper mechanism is installed directly at the neck/housing interface of the UTI unit. Its primary function is twofold: systematically stripping aggressive liquid cargo residue, hydrocarbons, and particulates from the graduated tape as it is reeled back into the storage drum, while maintaining strict containment of volatile organic compounds (VOCs) and toxic vapors to uphold closed/restricted gauging safety standards.

Worn, hardened, or degraded wiper elements compromise gas-tight integrity, contaminate the upper housing, foul internal slip-ring assemblies, and lead to graduated tape markings becoming illegible. Replacing the wiper assembly restores the mechanical integrity and hermetic seal of your UTI unit to factory specifications.

Key Features

1. Dual-Action Cleaning & Stripping: Efficiently scrapes liquid and heavy sludges off both the graduated face and back of the ETFE-jacketed tape simultaneously to prevent gumming of the winding spool.
2. Hermetic Pressure Containment: Forms a tight mechanical seal around moving tape profiles to eliminate fugitive cargo VOC emissions up to rated working pressures.
3. Hydrocarbon & Chemical Resilience: Constructed from premium FKM elastomer compounds to prevent swelling, blistering, or premature hardening in aggressive cargo environments.
4. Electrostatic Grounding Path: Ensures uninterrupted electrical continuity from the graduated steel core to the device housing, preventing dangerous static charge accumulation.
5. Modular Drop-In Replacement: Fast installation using standard hex fasteners directly onto the guide neck without requiring recalibration of the electronic sensing probe.

Applications

• Crude Oil Tankers (VLCC/Suezmax/Aframax): Custody transfer, ullage verification, and free-water interface dipping under inert gas pressure.
• Chemical Tankers (IMO II & III): Closed ullage measurement of refined petrochemicals, aromatics, and alcohols without vapor release.
• Product Tankers & Bunker Barges: Routine line blending, inventory control, and cargo tank dryness checks.
• Offshore Floating Production (FPSO / FSO): High-frequency cargo storage tank level monitoring in severe offshore marine climates.
• Shore Terminals & Tank Farms: Restricted and closed roof tank inspection.

Frequently Asked Questions

What are the symptoms of a worn Honeywell Enraf tape wiper assembly?

The most common indicators are liquid cargo leaking into the upper spool housing, oil slinging against the window during tape retrieval, volatile vapor escaping the top housing during gauging under inert pressure, and physical drag when winding the tape reel.

Can the tape wiper assembly be replaced while the UTI tape remains inside the housing?

Yes. The assembly is designed as a split/slotted modular kit, allowing field engineers to unbolt the wiper flange and swap the elastomeric inserts without disconnecting the sensing probe head or unspooling the entire 15m, 30m, or 35m graduated tape.

How often should the UTI tape wiper be replaced?

Under normal chemical/product tanker operational profiles, it is best practice to replace the tape wiper annually during routine intermediate calibration or immediately following any accidental cargo back-flooding event.

Is this tape wiper assembly compatible with both GTex and RTex devices?

Yes. Both the HERMetic UTImeter GTex (gas-tight) and RTex (restricted) share identical mechanical tape guidance necks and mounting bolt circles. Ensure that the perimeter housing gasket is inspected whenever replacing the wiper on GTex units to preserve gas-tight certification.

Does replacing the wiper assembly affect probe calibration?

No. The tape wiper is a mechanical sealing and cleaning interface. It does not contact the internal RTD, temperature probe circuitry, or interface sensor logic, meaning re-calibration of temperature or ullage electronics is not required.
