Inspection of pipeline and hose

A inspection of pipeline and hoses carrying everything from water to crude oil, the pipe is vulnerable to attack by internal and external corrosion, cracking, third party damage and manufacturing flaws.

If a pipeline carrying water springs a leak bursts, it can be a problem but it usually doesn't harm the environment. However, if a petroleum or chemical pipeline leaks, it can be a environmental disaster.

In an attempt to keep pipelines operating safely, periodic inspection of pipelines and hoses of AIM Control Inspection Group are performed to find flaws and damage before they become cause for concern.

When a pipeline is built, inspection personnel may use visual, X-ray, magnetic particle, ultrasonic and other inspection methods to evaluate the weld seams and ensure that pipelines are of high quality.

Sections of pipeline are left above ground like shown above, but in most areas they get buried. Once the pipe is buried, it is undesirable to dig it up for any reason.

Even though X-ray inspection of pipeline competes with other technologies at pipe mills, for example ultrasonic, as imaging technology radiography offers decisive advantages.

  • Replacement for film when inspecting pipe ends

  • Rapid inspection of longitudinal and spiral welds

  • Post-inspection of ultrasonic indications

A regular inspection of pipeline's welds for weak points is stipulated by law in many countries, for instance at nuclear power plants or in the chemicals industry, oil / gas

  • Crack identification

  • Verification of bonding flaws

  • Detection of inclusions

Engineers have developed devices to inspection of pipeline, called "pigs", that are sent through the buried pipe to perform inspections and clean the pipe. If you're standing near a pipeline, vibrations can be felt as these pigs move through the pipeline. The pigs are about the same diameter of the pipe so they range in size from small to huge. The pigs are carried through the pipe by the flow of the liquid or gas and can travel and perform inspections over very large distances. They may be put into the pipe line on one end and taken out at the other

Pigs use several nondestructive testing methods to perform the inspections of pipeline. Most pigs use a magnetic flux leakage method but some also use ultrasound to perform the inspections. A strong magnetic field is established in the pipe wall using either magnets or by injecting electrical current into the steel. Damaged areas of the pipe can not support as much magnetic flux as undamaged areas so magnetic flux leaks out of the pipe wall at the damaged areas. An array of sensor around the circumference of the pig detects the magnetic flux leakage and notes the area of damage. Pigs that use ultrasound, have an array of transducers that emits a high frequency sound pulse perpendicular to the pipe wall and receives echo signals from the inner surface and the outer surface of the pipe. The tool measures the time interval between the arrival of a reflected echos from inner surface and outer surface to calculate the wall thickness.
