How to Measure Relative Humidity and Dew Point in the Field?
There are two basic methods of measuring Relative Humidity and Dew Point Temperatures in the field. These are addressed in ASTM E 337, Standard Method for Measuring Humidity with a Psychrometer (The measurement of Wet and Dry Bulb Temperatures). One is with a sling psychrometer and the second is with the newer electronic meters. The […]
Electronic Ambient Meters or Sling Psychrometers, what should I use?
It is strongly suggested that electronic meters are used instead of sling psychrometers. This ensures the highest accuracy. Nevertheless, sling psychrometer are still widely used in the field. We will guide you to properly use the sling Psychrometers and electronic meters. It is highly recommended to follow this procedure to minimize any errors. SLING PSYCHROMETER. […]
6 Considerations for coating rehabilitation
The selection of a suitable pipeline repair/replacement coating is from a technical point of view the major decision to be made for a rehabilitation project. Rehabilitation seeks to re-establish coating efficacy to its original state. This does not mean that the same coating must be used for rehabilitation; often more state-of-the-art coatings are employed. Current […]
When do you need to rehabilitate a pipeline?
The rehabilitation of pipelines is in many cases forced upon operators by the fact that leaks occur (severe pitting) or extended general corrosion has been recognised on the steel surface. Various inspection techniques are applied generate information about the condition of the steel surface, such as: Intelligent PIG runs. This is an inspection robot, that […]
