Leak Detection in Oil & Gas
Pipelines Service in Qatar
INTRODUCTION
Pipeline networks are a mode of transportation for oil, gases and other fluid products. As a means of long-distance transport, pipelines have to fulfill high demands of safety, reliability and efficiency. If properly maintained, pipelines can last indefinitely without leaks. Some significant leaks that do occur are caused by damage from nearby excavation, but most leaks are caused by corrosion and equipment failure and incorrect operation.[1]

EQUIPMENTS USED
- Helium Gas
- Agilinet Harsh Environment Probe
LEAK DETECTION USING HELIUM TRACER GAS
LEAK DETECTION USING HELIUM TRACER GAS
- Even when a leak is present helium will not readily reach the test connection. Maximum flow through a pipe is at its center and flow is near zero at the wall. This greatly inhibits detection of helium.
- The Harsh Environment Probe can be inserted in the pipe for faster detection and greater sensitivity. Alternatively it can sample at a vacuum pump exhaust or steam ejector
