MF30
Hatch Cover Tape
The function of hatch cover tapes is to protect the metal hatch covers on carriage ships
against leakage of water into the carriage area.
Extreme weather conditions often damage hatch covers making them prone to leakage, which may lead to damage of 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.
Mareflex MF 30 is composed of a bituminous mass which has the appropriate viscidity in order to
ensure a watertight protection. It is equipped with polypropylene foil from one side and a release liner
from the other. The tape is available in 20 meters rolls, 100mm and 150mm wide.
General regulations regarding Hatch Covers may be found in the 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 weathertightness. 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 cargoes carried. The material and form of gasket selected is to be considered in conjunction with the type of cover, the securing arrangement and the expected relative movement between cover and ship structure. The gasket is to be effectively secured to the cover.
