Pressure Reducing Coils
Introduction
Pressure Reducing Coils (PRC), are used to enable the sampling of process fluids from high pressure process systems. By tapping off a small amount of the process fluid and passing it through the pressure reducing coil, sampling can occur at atmospheric pressure and low flow rate.

PRC Process
In operation, the process fluid tapped from the main high pressure process line is passed through a long coil of narrow bore tubing. High frictional losses, due to the narrow bore size, reduce the pressure and the flow rate of the process fluid.
In the PRC, the pressure is reduced to a level to permit safe sampling to atmospheric pressure.
Advantages To PRC's
Pressure reducing coils have many advantages over other pressure reducing systems such as active samplers which require o-rings, actuators, power connections and controls. Some of these advantages are:
- no moving parts
- robust
- simple
- safe
- no cavitation concerns
- the fluid is cooled as it passes through the coil
Numet Pressure Reducing Coils
Numet offers a wide range of pressure reducing coils which are easily adaptable to match the requirements of different process fluids and operating conditions. Furthermore, Numet pressure reducing coils can be supplied as seismically qualified units, if required, to meet any specific site requirements.
