Pipeline sampling

Application Summary


Pipeline Sampling


Removing samples from gasoline and oil pipelines for content analysis for safety and preview of crude prior to processing

How It’s Used

Extracting pipeline content through a bypass loop for sample isolation

Key Feature

High system pressures and abrasion resistance

End Equipment

Pipeline Sampling Equipment

Pump Function



Gasoline and oil

Flow Rate

11 to 19 L/min (180 to 300 USG/hr)

Differential Pressure

<1500 psi (<103 bar)

Applications Overview

Pipeline sampling enables monitoring of pipeline flow content for safety reasons as well as previewing crude oil content prior to arrival at the processing plant.

The sampled fluids are usually either oil or gasoline, at ambient temperature. Pipeline pressures can be as high as 1500 psi (103 bar). Pump differential pressure is low, and flow rate must be accurate to achieve proper sampling.

Gear pump extracts samples from a pipeline for automatic analysis.
