6.3 PIPEWORK
GENERAL
All pipework for water services should be of a suitable material and capable of withstanding working
pressures of up to 16 bar. The pipework has been standardised at 15 mm O.D. with a minimum wall
thickness of 1 mm. For example: ASTM B111-69 alloy 706 - or BS 378/2871 type CN 102-0.
Air signal pipework should be copper, and generally be 6 mm O.D. x 4 mm I.D.
The exception in this sizing is the air supply for the window wash pump mounted on the skid, and
shown as V12. These lines are 8 mm O.D. x 6 mm I.D. (ASTM B75-68 alloy 122 - or BS 2871/1971
type C106-0).
Pipework must be clean and oil free prior to fitting and care must be taken to ensure all joints are
leak tight. Failure to ensure this will adversely affect system function, particularly if air leakage is
evident on pump suction lines. Ideally all joints should be made using brazed couplings. If piping is
being installed during a sea passage then compression fittings may be used. These couplings
should be of a salt water resistant material, and the use of stainless steel compression rings may be
necessary if a non-flared tube end technique is used to make the joints. Mild steel couplings must
not be used. Pipework must be adequately clipped and supported, and shall not impose any strain
or force on equipment, e.g. pump or skid assembly. Pipework must also be protected in exposed
situations. In those cases where the water discharge from the ballast skid is taken to a slop tank, if
the ship has an inert gas system, a loop-seal arrangement must be fitted in the discharge line to
prevent contamination being forced back down the line. Also measures must be taken to prevent the
discharge from free-falling into the tank. This is usually achieved by diverting the flow against the
bulkhead of the tank.
