Steam receivers
Subregulation 1
Every steam receiver shall be —
of good construction, sound material and adequate strength;
free from patent defects; and
properly maintained.
Subregulation 2
Every steam receiver that is not constructed and maintained to safely withstand either the safe working pressure of the steam boiler or the maximum pressure which can be obtained in the pipe connecting the receiver with any source of supply, shall be fitted with —
a suitable reducing valve or other suitable automatic appliance to prevent the safe working pressure of the receiver being exceeded;
a suitable safety valve so adjusted as to permit the steam to escape as soon as the safe working pressure is exceeded, or a suitable appliance for cutting off automatically the supply of steam as soon as the safe working pressure is exceeded;
a correct steam pressure gauge indicating the pressure of steam in the receiver;
a suitable stop-valve; and
except where only one steam receiver is in use, a plate bearing a distinctive number which shall be easily visible.
Subregulation 3
The safety valve and steam pressure gauge referred to in paragraph (2) shall be fitted either —
on the steam receiver; or
on the supply pipe between the receiver and the reducing valve or other appliance to prevent the safe working pressure from being exceeded.
Subregulation 4
For the purposes of paragraph (2)(a) to (d), any set of receivers supplied with steam through a single pipe and forming part of a single machine may be treated as one receiver if the set of receivers is fitted on the single pipe.
Subregulation 5
For the purposes of paragraph (2)(a), (b) and (c), any other set of receivers supplied with steam through a single pipe may be treated as one receiver if the set of receivers is fitted on the single pipe, provided that the reducing valve or other appliance to prevent the safe working pressure being exceeded is fitted on that single pipe.
Subregulation 6
Subject to paragraph (7) and regulation 31A, every steam receiver shall be examined by an authorised examiner —
at least once every 2 years; and
after any extensive repairs.
Subregulation 7
