ABSTRACT:
A fluid pressure reduction system includes two streams, each stream having pressure regulators 19 & 20, 32 & 33. Isolation slam shuts 16 and 30 are provided in respective streams. A sequence tester 40 allows a sequence of test operations to be effected such that the slam shuts can be opened and closed and the working pressure settings to the regulators can be changed to check system integrity. These tests can be effected without interrupting the supply of gas through the system. It is also possible to carry out the sequence from another location.
