A metallic coating (20) is produced on a non-weldable inorganic substrate (6) by hot-spraying on a hot-sprayed intermediate layer (19) of refractory metal alloy chosen from nickel-chromium alloys and nickel and titanium aluminides. This intermediate layer itself may be deposited on an undercoat (18) of a ceramic chosen from aluminium and zirconium oxides and titanium hydrides, which is formed by hot-spraying on the inorganic substrate (6).

A coastal installation for loading or unloading liquefied natural gas comprises a fixed tower installed on a seabed close to a coast and carrying at the top a rotating mooring arm and a rotating loading arm. Cryogenic pipes connect the coast to the tower, the pipes passing from the coast to below the tower inside a tunnel and then up the tower in at least one vertical casing which penetrates into the tunnel at a point vertically in line with the tower, the upper ends of the pipes being connected to pipes carried by the loading arm by a rotating joint. The cryogenic pipes are thus sheltered against the sea and access to the installation is possible for ships in practically any weather.

A control valve comprises a body having a fluid inlet and a fluid outlet and a rotary member provided with two separate internal passages, each capable of connecting the fluid inlet to the fluid outlet, according to the angular position of the rotary member in the said body. A control system is arranged in one of the passages for controlling fluid along the passage independent of the angular position of the rotary member, while the control of flow of fluid in the other passage is effected by adjustment of the angular position of the rotary member. The one passage is the main passage for normal use and the other passage is a secondary or by-pass passage for use when work is required to be done on the control system in the one passage. The control system in the one passage comprises valve members operated by a rod for closing seats in the passage.
