Check the drill pipe thread
It is important to check your threads for wear and make sure they are free of sand, dirt and grit. Foreign debris will prematurely wear the threads. You should visually inspect the connections for galling or sharp threads. How do I know when the rod is worn out? You don’t. However, there are a couple of things you can do to assess the current condition of your rod. First, visually inspect ...

FE model updating of welded structures for identification of defects
A non-destructive evaluation procedure for identifying defects using finite element (FE) model updating based on natural frequencies is presented in this paper. Welded structures that are intended to represent a common configuration used in automotive body construction are investigated. The first procedure is to find the measured natural frequencies of both benchmark and defective structures, by ...

Aircraft Engine Remote Visual Inspection
An aircraft MRO center was in need of an easy to use borescope for use in a wide variety of applications on both turbine and piston powered aircraft. The VJ-Advance (VJ-ADV) from RF System Lab was selected because of its unique combination of features and very competitive price. Using the VJ-ADV, technicians are now able to conduct engine and airframe inspections quickly and easily, documenting ...

Comparison of core sampling and visual inspection for assessment of concrete sewer pipe condition
Sewer systems are costly to construct and even more costly to replace, requiring proper asset management. Sewer asset management relies to a large extent on available information. In sewer systems where pipe corrosion is the dominant failure mechanism, visual inspection by closed circuit television (CCTV) and core sampling are among the methods mostly applied to assess sewer pipe condition. ...

Confined Space Visual Inspections
What is a Confined Space? Confined Space refers to any place, including any vessel, tank, container, pit, bund, chamber, cellar or any other similar space which, by virtue of its enclosed nature, creates conditions that give rise to a likelihood of an accident, harm or injury of such a nature as to require emergency or rescue action. Many workplaces contain areas that are considered ...

Is Visual Inspection an Effective NDT Method?
Is visual inspection effective? Overall, the visual inspection method on its own cannot produce the same quality results as other nondestructive testing (NDT) methods. For one, it cannot detect certain minute flaws regardless of how keen an eye or how much experience an analyst has. Even the use of visual aids and tools is sometimes insufficient—and even minor defects may develop into ...

Comparison of different radar-raingauge rainfall merging techniques
The improvement of precipitation estimation with the use of radar-raingauge rainfall merging techniques is influenced by several factors, such as topography, storm types, raingauge network density for adjustment, data quality and the rainfall accumulation time. However, the influence of the raingauge network configuration on the performance of radar-raingauge merging methods is often ignored. ...

Regional Taiwan rainfall frequency analysis using principal component analysis, self-organizing maps and
L -momentsThe objective of this paper is to propose an approach, which consists of principal component analysis (PCA), self-organizing maps (SOM) and the L-moment method, for improving estimation of desired rainfall quantiles of ungauged sites. Firstly, PCA is applied to obtain the principal components. Then SOM is applied to group the rain gauges into specific clusters and the number of clusters can be ...

Are Oil and Gas Visual Inspections Enough?
With so many small anomalies that can hamper asset performance, conventional visual inspections may not be sufficient. This is especially true in the hydrocarbon industry, where detailed oil and gas visual inspections often depend on the use of advanced nondestructive testing (NDT) techniques. To achieve a robust inspection, consider ultrasonic testing (UT) and eddy current testing (ECT). Both ...

Heron Articulating Rigid Videoscope is perfect for inspecting Scuba Cylinders
Scuba cylinders need to be visually inspected a minimum of once a year, and often times more frequently depending on the use of the cylinder. These inspections are done to ensure the ongoing safe use of these cylinders. Scuba divers rely on them completely when diving, and therefore they need to be maintained excellently. Scuba cylinders come in various sizes and hold air at pressures up to 300 ...

Ultrasound Case Study on a 13800/4160V Plant Main Substation
Challenge: A power outage caused by a ground fault in a 13800/4160 volt plant main substation. The outage was caused by a main substation tripping on ground fault but the issue was what caused this. Solution: Initially both an infrared and ultrasound inspection was performed around the perimeter of the substation with no indication. A closer inspection was required. An external infrared ...

.35mm Ultra Thin HQ Borescope now available on demand
We will now be carrying an Ultra Thin HQ Borescope that will measure only 0.35mm in diameter. As our thinnest diameter fiberscope yet, this fiberscope will allow places with even smaller access points to be visually inspected. This .35mm borescope features the same German made high resolution Quartz Fibre optic bundle used in our other Ultra Thin HQ Borescopes. This HQ fiberscope also comes with ...

Ultrasonic Hull Inspections: How to Find the Right Equipment
Hull inspections keep crew, ship, and cargo safe at sea. Not only is it plain good sense to periodically ensure the seaworthiness of any vessel, but it can also be required by law for ships registered in the U.S. and other countries. Hull inspections can be conducted visually in some cases, but for the best results, ship owners rely on nondestructive testing. Marine nondestructive testing, such ...
