Plastics Pipes for Air Leads Hydraulic Systems & Fluidics

Consumption of a wide range of ~lastics FOI- pipe applications is increasing quite rapidly and of the more specialist applications those for air ieads, hydraulic systems and fluidics are some of the niost varied arid perhaps lesser known. 

Tubing is used extensively for process instrument air lines as single tubing or cabled instrumentation air and/or . hydraulic tubing including when desired electric cable for telephone signal, power or thermocouple measurement. 

Air leads are used in the main for pneumatic control of valves, switchgear or pressure readings in areas where pneumatics are considered more desirable than, say, electrical control in sites that have particularly stringent fire regulations. Such sites would be refineries, generai petro-chemical complexes or explosive plants. An increasing use of single way tubing is a G.P.O. application in automatic telephone exchanges where nitrogen is passed along a single low density polyethylene, iamir~ated polyethylene aiuminium, polyethylene tube, in order to continually dry and partially pressurise, for. cleanliness, contactor switches.
