SRUT Principle Short range ultrasonic testing (SRUT) is an application of guided ultrasonic sound waves using special types of probes. When the guided waves hit the discontinuities, the mode converted sound is reflected and received by the transducer.
WHAT ARE THE BENEFITS OF SRUT?
• Tank Inline inspection is possible for annular plates (up to 0.7 meter to 1 meter) while the product is still in tank and inspection will be perform from outside on projection plate. • The support structures surrounding the area of interest need not be removed. • Only one side access is needed. • SRUT is useful for detection of discontinuities related to loss of wall thickness such as corrosion, pitting, erosion, etc. • The tolerance for dimensions of a defect is usually within 0.040” for both length and width. • Multiple scans can be stitched together to show a complete image of the inspection zone. • SRUT can be used on a wall thickness ranging from 6 mm to 25 mm.
3D laser scanning for tank calibration first in Pakistan SGS Pakistan becomes first inspection company in pakistan to offer 3D laser scanning for tank calibration, with applications in the oil & gas and industrial manufacturing industries. The storage tank calibration is the process by which the exact volume of your tank is calculated in line with specified measurement standards. This process is key to obtaining accurate measurements of custody transfer quantity and keeping good contractual relationships with your clients and governing bodies. With 3DTank Calibration, which is a new concept introduced by SGS, companies can improve productivity & safety while producing unparalleled results! 3D Laser scanning, which is a remarkable technology for tank calibration measures and verifies quantities and volume in petroleum, fuel and chemical storage tanks.
Identify threats and address issues of insulation damage before they become CUI Corrosion under insulation detection through Advance Pulse Eddy Current Testing (PECT) technique In any industry that makes use of metal structures such as petrochemical, oil and gas, shipping and civil engineering, the detection of corrosion under layers of bricks, coating and insulation is not possible without removing insulation/layer. PECT is making this possible to detect corrosion in these conditions without removing the insulation. We understand that CUI is a huge problem for industry. It decreases productivity, endangers the environment, and puts workers at risk. It has even resulted in loss of life. Damage from CUI costs businesses around the world billions of dollars every year. Corrosion is a key safety and profitability consideration in an environment that makes use of steel structures, as the failure to identify and act on any form of corrosion can have serious consequences. WHY IS IT POPULAR? IS THE TECHNIQUE WORTHY ENOUGH?
FAST AND EFFICIENT
SGS’s 3D scanning services save clients time and money. Equally effective indoors and out, laser measurements are easier and quicker to collect, they also remove the need to fill tanks, pipes and similar spaces with liquids or gases. Data is collated direct from the scanning equipment ensuring accuracy, and significantly reducing the risk of measurement errors. In addition, the safety of inspectors is improved as there is less need for working at height and fewer inspectors are required on-site.
Solution for tank inline, pipe under support and difficult to access location with SRUT Technique Good news for the industry stakeholders as SGS Pakistan is glad to announce Short Range Ultrasonic Testing (SRUT) first time in Pakistan, a solution which is used for In-Line Inspection for corrosion detection in tanks, pipes under support, vessels and any other inaccessible or difficult locations.
As this technology does not require the removal of insulation or coatings to test the area, we discuss some of the benefits of the Pulse Eddy current technique that include but not limited to the following: • Fast results (no time wasted creating a clean and dry test environment) • Saves costs (no resources required to clean a coated area in order to test for corrosion beneath) • Reliable • Safe (no surface reparation is required, so it is particularly advantageous where surface grinding may be dangerous if the pipe or tank carries hazardous products) • Ease of use • Easy retrieval of data for comparison and evaluation
The technique is popular because of it’s unique characteristics, pulsed eddy current is a fast, reliable and cost-effective non-destructive testing solution for detecting flaws and corrosion, especially in situations that are hard to access and where dirt, corrosion, water, concrete, coatings or even natural marine growth make it difficult to reach the surface area. It’s versatile and easy to operate and can play a crucial role in the inspection strategy of a huge variety of operations across many different industries.
SHORT RANGE ULTRASONIC TESTING (SRUT) WILL EQUIP YOU TO DETECT:
WHERE THIS TECHNIQUE CAN BE APPLIED?
• Corrosion under pipe supports (CUPS) • Pipeline inspection for soil to air and soil to concrete interface • Tanks Annular plate inspection from outside of the tanks while the product is inside. • Vessel inspection for areas which is difficult to access.
• Fireproofed installations such as tank supports • Port structures
• Jetties • Bridges • Ships and boats • Buried piping
