Pipeline Sampling

Application Summary

Application Pipeline Sampling
Description Removing samples from gasoline and oil pipelines for content analysis for safety and preview of crude prior to processing
How Used Extracting pipeline content through a bypass loop for sample isolation
Key Feature High system pressures and abrasion resistance
Micropump Products GDR
End Equipment Pipeline Sampling Equipment
Pump Function Circulation
Fluids Gasoline and oil
Flow Rate 11 to 19 L/min (180 to 300 USG/hr)
Differential Pressure <1500 psi (<103 bar)

Application 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.

Diagram: Critical Pumping Requirements

Gear pump extracts samples from a pipeline for automatic analysis.

FLOW RATE: 11 to 19 L/min (180 to 300 USG/hr) We have variable speed pumps with flows from 1.74 to 26.6L/min (27.6 to 421 USG/hr)
MAX SYSTEM PRESSURE: 1500 psi (103 bar) Our pumps operate up to 1500 psi (103 bar) max system pressure
ABRASION RESISTANCE FOR GRITTY CRUDE OILS Our construction materials maintain long life in abrasive environments
CONTROLLED, PULSELESS FLOW We offer positive displacement gear pumps for precise, pulseless flow for sample extraction
LEAK-FREE OPERATION Our magnetic drives eliminate dynamic shaft seals, keeping the oil and gas securely inside the pump and potential contaminants out
MAINTAINABILITY We offer Service Kits for easy field serviceability

Micropump Products Optimized for this Application

Micropump Series GDR is primarily used as a sampling pump. With A10 steel gears the GDR Series should be used to increase pump life when sampling gritty crude oil.
