Mareflex GmbH

Advanced and certified anti-splashing tapes help to control oil spraying and leakages by the latest IMO SOLAS Consolidated Edition 2009, Chapter II-2 / Regulation 4, item 2.2.

General description

The Mareflex MF01 and MF02 anti-splash tapes were designed to prevent pipeline installations from oil sprays by the latest SOLAS Consolidate Edition 2004 Regulation II-2/4.2.2.5.3. Specially constructed to withstand high temperatures and high pressure, they serve as protection against uncontrolled spraying of flammable liquids onto hot surfaces, which might be a cause of fire or explosion. 

Antispray tapes are applied around pipe flanges and fittings to direct any potential leakage away from the possible areas of ignition. They are equipped with a flame-retardant (self-extinguishing) adhesive layer to enhance safety standards even further. The adhesive layer is very strong and resistant to high temperatures.

The structure of Antispray Tapes

MF01 and MF02 are produced of the highest quality materials selected to ensure the best possible protection against high pressure and high temperatures while maintaining the elasticity necessary for a quick and easy installation. 

MF03 and MF04 are new-generation Antispray Tapes designed to protect pipeline installations against oil spraying and leakages by the latest SOLAS Consolidated Edition 2001, Regulation II-2/4.2.2.5.3.

General description

The MF03 and MF04 upgraded versions of well-recognised MF01 and MF02 Antispray Tapes offer significant improvements in performance, with the ability to withstand even higher pressure, up to 25 bars and 55 bars, respectively. The MF04 is an ultra-strong solution for the most demanding applications in the marine, offshore, oil & gas and petrochemical industries.

The function of Mareflex anti-splashing tapes 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 are the potential sources of ignition.

General description

Inspection Point Labels are designed to identify inspection locations on non-insulated pipes and equipment to monitor their structural integrity and to detect surface and subsurface defects.

NDT Labels are used in Process Safety Management in industries that require NDT and have formalised processes for its use, including oil & gas, chemical, petrochemical, maritime, food processing and transportation sectors. Some non-destructive labels are equipped with the text field to record data, additionally secured with a clear laminate to seal written information. Each label is resistant to chemicals such as isopropyl alcohol, detergents, engine oils and moisture.

Application guidelines

The minimum temperature for NDT Labels application is + 15°C.

To obtain the best bonding conditions, the application surface must be clean, dry and at room temperature or slightly above. Any loose dirt, grease, or corrosion should be removed with isopropyl alcohol or heptane before the application.

The adhesive is a high-performance acrylic for strong bonding also on rough surfaces.

The initial bond is achieved through a rub-down pressure. The higher the pressure, the stronger the adhesive bond. The acrylic adhesive takes 48-72 hours to reach 90% of the final bond strength and two weeks to achieve 100% bond strength.

General description

Extreme weather conditions often damage hatch covers making them prone to leakage, which may lead to damage to the transported goods.

Mareflex MF 30 Hatch Cover Tape is a self-adhesive, heavy-duty sealing tape which protects goods against seawater. MF 30 Tape is made of a very enduring and flexible material which guarantees protection in all weather conditions.

Technical specification

Mareflex MF 30 is composed of a bituminous mass which has the appropriate viscidity to ensure watertight protection. It is equipped with polypropylene foil from one side and a release liner from the other. The tape is available in 20-meter rolls, 100mm and 150mm wide.

Regulatory requirements

General regulations regarding Hatch Covers may be found in Regulation UR S21, point 4.2 issued by the International Association of Classification Societies (IACS).

IACS Recommendation No 14 “Hatch cover securing and tightness” provides details regarding Hatch Cover sealings:

2.2.2 Weathertight sealings are to be obtained by a continuous gasket of relatively soft elastic material compressed to achieve the necessary weather tightness. Similar sealing is to be arranged between cross-joint elements. Where fitted, compression flat bars or angles are to be well-rounded where in contact with the gasket and are to be made of a corrosion-resistant material.

2.2.3 The gasket material is to be of a quality suitable for all environmental conditions likely to be experienced by the ship and is to be compatible with the cargo carried. The material and form of gasket selected are to be considered in conjunction with the type of cover, the securing arrangement and the expected relative movement between the cover and ship structure. The gasket is to be effectively secured to the cover.

General description

The MF40 Pipe Repair Kit includes a fibreglass polyurethane-soaked reisin bandage and a putty – a dough-like mouldable substance.  MF40 can be applied to the most commonly used pipes: PVC, fibreglass, steel, copper, concrete and others. 

The kit can be used on pipes with internal pressure up to 400 psi (27,5 bar).  The installation process takes only a few minutes and a pipe is ready to be used within an hour.

• Hardens in minutes
• Bonds to most Pipe Materials
• Suitable for T and elbow joints
• Reduce the cost of repair
• Resistant to most chemicals
• (applicable to various pipe contents including mild acids and alkalis, water, hydrocarbon, fuel, bases, solvents, slurries, gases, chemicals, organic salts etc.)
• High-temperature resistance
• Continuous use: from -30°C to +120°C
• Short time (Peak): up to +190°C

Maintenance and storing

MF40 should be stored in the original box at 21°C and 50% relative humidity and used within 36 months from the production date visible on the aluminium foil bag.

Mareflex provides the kit in ready-to-sell, individual cartoon boxes with English instructions inside.

General description

MF50 Anti Leak is a self-fusing silicon tape for emergencies and all-purpose repairs. MF50 can be applied on a wide range of surfaces and is versatile in use, including leaking pipes and hoses, electrical connections, cables, hand tool handles and much more. Anti Leak Tape is resistant to UV, fuel, water, oils, acids and a wide range of solvents.

How it works

The tape creates a permanent air-tight and water-tight seal immediately after application. It ensures anti-corrosive and electrical protection. It is very easy to remove and leaves no sticky residue.

Application guidelines

• Clean the surface from dirt, oil etc. before the application.
• Attach the beginning of the tape close to the damaged area and start wrapping it around (with tension).
• Keep stretching the tape until a 50% overlap is achieved. Once overlapped, the tape will fuse.
• Finish the wrapping around the problem area and press the tape firmly into place.
• For high-pressure leaks, additional wrapping may be required. Most hose repairs can be repaired with 3-5 layers by wrapping 3 to 5 inches in each direction away from the leak point; however, additional strength can be added simply by wrapping more layers of the MF50 tape.
• For electrical wiring, it is not necessary to stretch tightly. It will be more resilient to abrasion when it is not stretched too tightly.

Removing:

• Cut the tape using scissors or a knife.

Maintenance and storing

• The shelf life of MF50 is at least 5 years from the date of dispatch by Mareflex when stored in the original box at 21°C and 50% relative humidity.
