803.5 MIscellaneous Systems
coutmi piping: all piping, valves, and fittings used to interconnect air, gas, or hydraulically operated control apparatus or instrument transmitters and receivers.
gas processing plant: a fad lity used for extracting commercial products from gas.
in.ctrunsent piping: all piping, valves, and fittings used to connect instruments to main piping, to other instruments and apparatus, or to measuring equipment.
production facility: piping or equipment used in production, extraction, recovery, lifting, stabilization, separation, treating, associated measurement, field compression, gas lift, gas injection, or fuel gas supply. Production facility piping or equipment must be used in extracting petroleum liquids or natural gas from the ground and preparing it for transportation by pipeline
sample piping: all piping, valves, and fittings used to collect samples of gas, steam, water, or oil.
803.6 Meters, Regulators, and Pressure Relief Stations
customers meter: a meter that measures gas delivered to a customer for consumption on the customer’s premises.
meter set assembly: the piping and fittings installed to connect the inlet side of the meter to the gas service line and the outlet side of the meter to the customer’s fuel line.
monitoring regulator: a pressure regulator installed in series with another pressure regulator that automatically assumes control of the pressure downstream of the station, in case that pressure exceeds a set maximum.
prcssure-limitin station: consists of equipment that under abnormal conditions will act to reduce, restrict, or shut off the supply of gas flowing into a system to prevent the gas pressure from exceeding a predetermined value. While normal pressure conditions prevail, the pressure- limiting station may exercise some degree of control of the flow of the gas or may remain in the wide open position. Included in the station are piping and auxiliary devices, such as valves, control instruments, control lines, the enclosure, and ventilating equipment, installed in accordance with the pertinent requirements of this Code.
pressure-regulating station: consists of equipment installed for automatically reducing and regulating the pressure in the downstream pipeline or main to which it isconnected. Included are piping and auxiliary devices such as valves, control instruments, control lines, the enclosure, and ventilation equipment.
pressure relief station: consists of equipment installed to vent gas from a system being protected to prevent the gas pressure from exceeding a predetermined limit.
