A Guide to Mareflex Antispray Tapes. Why Is Spray Shielding Mandatory on Ships?

Mandatory Protection for Marine & Offshore Piping Systems

In high-risk marine environments, uncontrolled oil spray from piping systems can pose serious hazards – including fire, explosion and personnel injury. Even a fine mist of leaking oil can ignite instantly upon contact with hot surfaces within engine room compartments. That is why the use of spray shielding solutions is not just recommended, but mandatory under international maritime safety regulations, helping to prevent catastrophic incidents and ensure crew safety.

Antispray tapes, also known as anti-splashing or spray control tapes, are essential safety products designed to protect pipe flanges and valves from sprays of flammable liquids.


Purpose and Industry Applications

The MF03 Antispray Tape is a self-adhesive, high-performance aluminium tape engineered specifically for use on flanges, valves and pipe joints where there is a potential for high-pressure fluid leakage. Its primary function is to transform a mist of flammable substances into a liquid and allow it to drip away in order to eliminate the risk of flammable mist combustion. Leaks or sprays of pressurized fluids, such as hydraulic fluid, lube oil or fuel oils, onto hot surfaces or electrical components are the potential sources of ignition.

Antispray Tapes are widely used in:

  • Marine vessels
  • Offshore platforms
  • Petrochemical plants
  • Power generation facilities
  • Heavy industrial process installations


Exceptional Pressure Resistance: Up to 25 Bar

One of the key features that sets MF03 anti-splashing tapes apart from competing products is its pressure resistance. The tape is certified to withstand up to 25 bar – a significant improvement over many other spray control tapes on the market, which are typically rated for 15 bar.

This added resilience provides greater safety margins, particularly in critical systems operating under fluctuating or high-pressure conditions.


Certified Safety – Regularly Updated

MF03 anti-splash tape is tested and certified in accordance with SOLAS Consolidated Edition 2009, Chapter II-2/ Regulation 4, item 2.2.5.3., and its certifications are routinely renewed to reflect the latest international safety standards. This ensures the tape remains compliant with classification society requirements, such as DNV, China Classification Society, ABS, Class NK and Korean Register.

Each roll is marked with batch information and documentation is available for verification during inspections or audits.


Importance of Proper Installation

No antispray system is effective without correct installation. MF03 is designed for tight and secure wrapping around flanges and valves, and improper application may compromise its protective function.

To ensure full performance:

  • The tape must fully cover the protected element
  • It should be applied with consistent tension
  • The installation should include overlapping layers

Visual Design for Easy Identification

The MF03 Antispray tape features a silver reflective background with a bold orange Mareflex logo and the MF03 product symbol, which ensures easy identification during inspection. This design also helps to distinguish original Mareflex products from imitations or non-certified alternatives. Also technicians can instantly recognize the tape type during routine checks or emergency interventions.
