  1. The Acoustic Emission (AE) equipment uses the velocity of the sound in various materials to calculate how long it takes the sound waves to reach each sensor. Based off the difference in time, it can determine where the event happened along the structure.

  2. Acoustic emission non-destructively tests (NDT) all structures under stress by monitoring for fatigue cracks that produce sound waves after failure.

  3. Phased Array has the capability to shoot a large range of shear wave angles from 45-70 degrees. 2D images of the part can then be created to easily assess the data.

  4. Some of the most common applications of magnetic flux leakage (MFL) testing are to non-destructively test (NDT) for wire breaks on bridge cables, amusement park rides, and mining operation cables.

  5. No you cannot - stainless steel isn’t ferromagnetic. However, you can use Liquid Penetrant testing (PT) which is an alternative way to non-destructively test (NDT) for cracks on non-ferromagnetic material.

  10. No you cannot - stainless steel isn’t ferromagnetic. However, you can use Liquid Penetrant testing (PT) which is an alternative way to non-destructively test (NDT) for cracks on non-ferromagnetic material.

  11. TechKnowServ (TKS) also offers unparalleled visual inspection of wire ropes and can accommodate your industry needs from amusement inspection to more industrial applications.

  12. Yes TechKnowServ (TKS) is leading the industry in magnetic flux leakage inspection (MFL) of wire ropes and can meet the needs of varying rope diameters.

  13. When doing a weld inspection TechKnowServ (TKS) can use magnetic particle (MT), penetrant testing (PT), ultrasonic testing including phased array (UT, PUAT) and visual (VT). TechKnowServ (TKS) can inspect to AWS standards.

  14. Acoustic emission testing can be very useful in detecting cracks forming in vessels and pressure vessels, but can be applied to any part under stress. It has also had large success in monitoring processes to detect anomalies.

  15. Acoustic emission (AE) is an advanced method of nondestructive testing (NDT) that monitors the behavior of test parts under stress.

  16. Some of the most common applications of phased array testing (PAUT) are to scan for surface and subsurface flaws in test parts ranging from large floodway doors to small welds. The application is very broad and materials can vary, metal, composite, and PVC piping all are suitable to be tested by phased array (PAUT).

  17. The industry benefits of using array (PAUT) begins with cost for some applications. Phased array is the most cost effective way to inspect simple and complex structures, without sacrificing the validity and reliability of the inspection.

  18. Yes TechKnowServ (TKS) offers comprehensive inspection of steel, stainless steel, and polypropylene tanks to API-653 and STI-001 standards.

  19. When inspecting fiberglass reinforced plastic tanks (FRP) some of the common flaws we find during testing are cracking, corrosion linear breakdown, and delaminations.

  20. We lead the industry in fiberglass reinforced plastic tank (FRP) inspection. With methods in acoustic emission (AE), visual (VT), as well as strain measurement.

  21. Yes, TechKnowServ (TKS) has several courses in all of the different methods of nondestructive testing (NDT) which include, acoustic emission (AE: I, II, III), frac iron certification, guided waves (GWUT: I, II), magnetic particle / liquid penetrant testing (MT,PT : I, II), phased array ultrasound (PAUT: I, II), ultrasonic testing (UT: I, II, III), UT thickness testing (UT: II), and UT Weld Inspection.

  22. We offer industry leading flow iron recertification training which includes ultrasound (UT), magnetic particle (MT), visual (VT), and also train students on how to use and calibrate a pressure transducer.

  23. You can receive ASNT/ISO 9712 training through TechKnowServ (TKS). We offer a wide range of nondestructive testing (NDT) classes at our training facility, with industry leading personnel and equipment.

  24. The different methods of nondestructive testing (NDT) TechKnowServ (TKS) offers are ultrasound (UT), visual (VT), magnetic particle (MT), penetrant testing (PT), guided wave (GWUT), magnetic flux leakage (MFL), acoustic emissions (AE), and phased array (PAUT) .

  25. Yes, TechKnowServ (TKS) is able to apply rope access to a variety of inspection services.

  26. There are three levels of NDT of technicians I, II, III, level one being lowest and three the highest. The technician’s placements are based off certifications through employers or the ASNT.  Each of the level of training has different field work hour requirements per method of nondestructive test (NDT), well as written and practical exams for each. We personally train our technicians in house, to the industry standards as to ensure the integrity and reliability as a product.

  27. Nondestructive testing (NDT) is an inspection process that does not damage the test part.  It accesses the life expectancy and reliability of the piece of equipment being inspected. The testing helps to keep your industry processes running safely and efficiently. There are a wide array of industry applications including Oil and Gas, Construction, Military, Power generation, and various others.
