The pipeline is divided into long-distance pipeline, public pipeline, industrial pipeline, power pipeline and gathering pipeline, mainly used for transportation of crude oil, refined oil, natural gas, artificial gas, steam and industrial hazardous media. The pipeline is an important infrastructure people's lives, and occupies an extremely important strategic position in the national economy, known as the national lifeline.
China's 100% natural gas, more than 75% of the crude oil is transported by the pipeline. The fundamental way to ensure the safety of pressure pipelines is to improve manufacturing and installation quality and management of pressure pipelines, which relies on scientific and technological progress of inspection and testing technology.
Pressure pipeline safety involves the design , manufacture, installation, usage, inspection and transformation of pipeline , and is a highly technical project.
To ensure the safety of pressure pipelines must rely on scientific and technological progress.
The system to solve the main problems
1. non-destructive testing of oil pipelines
2.oil pipeline leak alarm
3.open fire alarm around oil pipeline
4.construction identification around oil pipeline
5.personnel identification around oil pipeline
The system is mainly through the infrared thermal imaging detection. the principle is the use of optical system of infrared cameras to gather infrared radiation energy of detected object . Infrared energy focused on the photoelectric detector and then converted to the corresponding electrical signal. And the signal then converted into temperature value of the measured target .
To detect the surface temperature of the various parts of detected object and then form distribution map of infrared radiation energy , known as thermal image.
The advantages of infrared thermal imaging detection:
It is an non-contact non-destructive testing technology and can realize up and down, left and right non-contact continuous scanning for the measured object.
high display sensitivity, high precision, 0.01 degrees temperature difference recognition and reliable test results.
Quickly predict problems. With a wide range of temperature measurement, as long as the measured temperature is above the absolute temperature of zero (-273 ℃), the detector will respond.
It can realize normal monitoring both day and night . Infrared thermal imaging detection is widely used in industry and many other industries, providing predictive detection and reference data for maintenance.
Infrared imaging detection technology features: Infrared detector with a focus length of 20cm to infinity is suitable for non-contact, wide area and large area nondestructive testing, and realizes pipeline heat preservation inspection, pipeline fire-resistant inspection, pipelines thickness changes detection and pipeline leaks and corrosion detection.
