English term or phrase:transverse rod
Outer coating of rust-sensitive steels shall be with primer.
Inner coating only if expressly specified.
Boreholes open to atmosphere such as testholes and vents shall be filled with putty resistant to sea water, grease or approved equivalent.
Nozzles shall be closed, e.g.
nozzle flanges by means of blind flanges or covers with rubber gaskets;
or (in case of welding bevels and accessibility from inside) by means of covers with rubber gaskets, held by a tension rod vertically welded to the inside of the cover bolted to a transverse rod supported at the vessel wall,
or (in case of welding bevels) by a buttwelded cap or a flat cover, designed for the test pressure.
If equipment is air-freighted all covers shall be loosened to allow pressure equalization during flight.
For sea transport or storage in marine environment:
Filling with 0.3 bar gage dry nitrogen or dry air (dew point -10°C) for static equipment and package units made of stainless steels, aluminium, copper and its alloys or rust-sensitive steels with stainless steel internals (incl. vane type separator internals, wire mesh demister, vane type distributors etc.).
For that purpose an easy accessible filler device (e.g. with threaded valve like vehicle-type valve) mounted on a temporary blind flange shall be used.
It shall be provided with a control pressure gauge (protected against mechanical damages).
The filler device shall remain on the equipment during the whole transport and site storage period.
A well visible danger sticker "Attention!
Internal pressure below 0.5 bar gage!", in case of nitrogen filling "Attention!
Danger of asphyxiation!
Venting prior to access!" shall be applied at each manhole and nozzle > DN300 / NPS12.
