Application Most boat fuel tanks do not have ay direct access into them, usually because the thickness of the tank does not allow a threaded entry port. The Drillsafe System has been used extensively throughout the petroleum industry and to date has provided more than 3,000 new access ports in petrol and diesel tanks throughout Europe, for such companies as BP, Shell and Esso. This technology is now available to the marine industry.
Process An entry hole is drilled into the tank, if it is a petrol tank, intrinsically safe drilling methods are used. The hole size is dependant upon the entry required. Entries are available as 2" and 4". A Viton 'U' profile seal is inserted around the hole and an internally threaded kebler is fitted. A jacking screw is then temporally fitted into the kebler and hydraulic pressure is then applied upwardly to the kebler. This then crimps into the Viton 'U' seal leaving a compressed fitting tested to 80psi pressure. The jacking screw is then removed and a blanking plug is screwed into the internally threaded kebler.
Advantages Having a blanked threaded entry directly into your fuel tank means that periodically this can be removed and a pipe inserted into the hole and by means of a simple hand pump, water and other contaminants can be removed. An access port means a fibre optic camera inspection is also possible to inspect the condition of the tanks and contents. Should your vessel ever suffer the "Diesel Bug", rectification treatment directly into the tank is available. As the insert is only fitted into the top of the tank, there is never a danger that leakage can occur, the insert and seals are capable of withstanding pressure up to 80psi.
Suitable for Steel, GRP and Plastic Tanks
