33、ing the tank contents and/or discharge equipment with steam 3.2 steam trap Self contained valve which automatically drains the condensate from a steam containing enclosure while remaining tight to live steam, or if necessary, allowing steam to flow at a controlled or adjusted rate 4 Requirements The
34、 extremities of the heating installation shall be fitted as follows: Each inlet shall be fitted with a valve PN 16, and a connection according to clause 6; Each outlet shall be fitted with a valve PN 16 or a steam trap. In order to drain condensate the outlet shall be situated at the lowest point of
35、 the steam heating installation. This outlet shall not be obstructed when the outlet valve is open. It shall be directed to the ground in such a way as not to present a danger to personnel or damage on brake parts or to other wagon equipment. 5 Positioning of connections The connections shall be pos
36、itioned entirely within the areas shown in Figure 1.

41、 permissible working pressure and temperature of the heating installation. At these maximum working conditions, the materials shall be compatible with the steam where they come in contact with it. 8 Marking The maximum allowable working pressure of the heating installation shall be legibly marked on
42、 the tank wagon close to the connections. Where the heating device can also be used for heating tank equipment, a diagrammatic representation of the use of the different devices shall be fitted on the tank wagon close to the connections. 9 Maintenance, tests and inspections 9.1 Maintenance Gaskets,
