Pipeline and pipe inspection is a vital service provided to many industries, often oil, gas, chemical and power. The main purpose of SMC producer inspection would be to maintain and enhance the integrity of the plant or system, in order to avoid failures, ensure safety standards, avoid accidents, adhere to government laws and save time and money.
Pipeline and pipe Inspection uses NDT (Non Destructive Testing) methods to undertake inspections, using very skilled personal often performing a number of methods to determine number of flaws, size, type and chance of each. Outcomes are summarised in a report with appropriate graphs and technical drawings to illustrate the a summary from the results after careful analysis with a trained technician.
Several different kinds of piping might be inspected, several of the main types include;
Above ground non insulated piping
Long pipeline runs
Short underground runs
Service Water systems in nuclear plants
Fire protection systems in nuclear plants
The Low Frequency Electromagnetic Technique (LFET) is often used because of its highly flexible nature. For rapid identification of total flaws, some kit for example the PS-2000 may be used, though it is also dedicated to screening mode to offer more in depth information, which may then be proved up via another technique say for example a-Scan Ultrasonics.
For much longer pipelines equipment including the LineCat excels. The LineCat is ideally designed for long pipeline inspection, because of its shape, and its particular self-propulsion. The LineCat is a rig that wraps around the OD (Outer Diameter) from the pipeline, propelling itself at 10 ft/minute. The LineCat uses the LFET technique just like the PS-2000 above, however because of its rapid independent nature, makes SMC pipeline non problematic, compared to a other systems that require manual movement via an operator.
In nuclear plants the primary concerns of piping inspections are service water system piping and fire protection system piping. These are generally inspected to quantify MIC (Micro-biologically induced corrosion) and FAC (Flow accelerated corrosion).
For shorter underground piping runs, equipment for example the Eagle-2000 system could be utilised. The Eagle-2000 uses SMC alu tube, and performs inspections 17dexypky the ID (Inner Diameter), obtaining on small flaws due to its high definition and small sensor size. It could provide realtime 3d data to analyse flaws instantly, and inspects through scale.
During inspection the same kinds of flaws often arise, attack by external and internal corrosion are normal, and also cracking, though 3rd party damage is one of the main culprit for a lot of the major flaws. Flaws caused during the manufacturing process can be acquired on too, though they’re generally rare to come across.
