6.1.1 Steam turbine piping systems are, in general, to comply with the requirements given in Vol 2, Pt 7, Ch 1 Piping Design Requirements and Vol 2, Pt 7, Ch 3 Machinery Piping Systems, due regard being paid to the particular type of installation.
6.1.2 Synthetic rubber hoses, with single or double closely woven integral wire braid reinforcement, or convoluted metal pipes with wire braid protection, may be used in condensate and lubricating oil systems. see also Vol 2, Pt 7, Ch 1 Piping Design Requirements.
6.2.1 Lubricating oil arrangements are to comply with the requirements of Vol 2, Pt 7, Ch 3 Machinery Piping Systems.
6.2.2 Where the lubricating oil for main propelling steam turbines is circulated under pressure, provision is to be made for the efficient filtration of the oil. The filters are to be capable of being cleaned without stopping the turbine or reducing the supply of filtered oil to the turbine.
6.3.1 Cooling water arrangements are to comply with the requirements of Vol 2, Pt 7, Ch 3 Machinery Piping Systems, as applicable.
6.4.1 Non-return or other means, which will prevent steam and water returning to the turbines, are to be fitted in bled steam connections.
6.5.1 Efficient steam strainers are to be provided close to the inlets to ahead and astern high pressure turbines, or alternatively at the inlets to the manoeuvring valves.
