  • Small Engine Inspection

    A small engine repair shop needed a borescope, primarily to conduct engine and valve inspections. The instrument had to small and portable, had to articulate in order view in inside of the combustion chamber, piston dome and valves, and it had to have image capture capability. The VJ-ADV from RF System Lab was selected because it met all of these requirements. In addition to saving time on ...

  • Environmental/Safety Management: Dissecting an OSHA Inspection

    Understanding OSHA inspections can help utilities prepare, preventing fines and penalties associated with non-compliance. While catastrophes and fatal accidents are obvious inspection triggers, almost half of OSHA (Occupational Safety and Health Admini- stration) visitations are complaint-driven. Therefore, the best way to avoid an inspection—and potential fines and penalties—is to eliminate ...

  • 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. This ...

  • Tips for Maintaining the Quality of Industrial Equipments

    For an enterprise dealing with industrial machinery whether in the generation of output or as a support function for the sideline activities, there is a prime need for such entities to hold its inspection checks and tests on a regular basis so as to ensure that suffice steps are followed in the maintenance of the plant equipments. Most often, the industrial apparatus deployed at the production ...


  • Comparison of the photoconversion of para-chlorophenol under simulated sunlight and UV irradiation in ice

    The photochemistry of para-chlorophenol (4-CP) was studied under simulated sunlight (λ > 300 nm) and UV irradiation by using a 125 W high-pressure mercury lamp with or without a hard glass as light source in an ice matrix. The experiments were carried out in a photochemical cold chamber reactor at −14 to −12 °C. The photoconversion rate, photoproducts and photoconversion mechanism of 4-CP were ...

  • Risk-based asset integrity management

    Within the area of management of process plant integrity, there has been a significant shift toward the adoption of risk-focused methods such as reliability centered maintenance (RCM) and risk based inspection (RBI), rather than following traditional preventative maintenance methods and prescriptive inspection intervals. There are various reasons for this trend, but the primary benefit that asset ...
