Sometimes problems are not apparent or may not even exist until coatings have been applied. Performing a moisture survey — an inspection of a building and its environment prior to performing any tests — will provide a clearer picture of the potential problems moisture in both liquid and vapor form can pose.

The floor is prepped (blasted or ground) around the test area - 3. This section of floor has not been prepped which could restrict the emission of moisture from the concrete rendering false test results. That, and the fact that there is a close crack, makes this an unsuitable test area - 4. This floor is clean, but it has not been properly prepped. Tight surface laitance will restrict the emission of moisture rendering lower (false) test results - 5. Exterior conditions such as snow piled against a building create potential for future moisture problems - 6. Moisture is trapped under entrance mats - 7. Moisture can lift coatings systems at saw cuts - 8. A hand-troweled finish on a floor patch - 9. Moisture damage to vinyl composite tiles is evident by the appearance of curling edges - 10.

TuyauterieIndex. décimale : 667.9 Revêtements et enduits Résumé : The major oil and gas companies in Saudi Arabia and the Gulf Coast Countries (GCC) own and operate an average of more than 33,000 km (20,000 miles) of oit and gas pipeline networking systems. Due to the differences in the geographical area of the region, the service life, operations, and maintenance costs of these pipeline networks vary and depend on the location of the pipeline. These cross-country pipeline locations run from East to West, North to South, and vice versa. The trunklines and the flowlines can be divided into two main exposure environments : dry sand areas and wet sand areas.
These existing pipelines are between 40 and 50 years' old, and the average design life span is between 20 and 25 years. The external protection coating systems applied to these pipelines varied from old cold-petroleum tape wrap to hot coal tar enamel (late 1950s—early 1980s), liquid coating, and fusion-bonded epoxy (FBE) as a single-coat powder coating from the mid-1980s to date, including three-layer polyethylene (3LPE and 3LPP) for cross-country pipelines. Flowever, the internai protection was not implemented until mid-1980s, with liquid coatings, first in the field, and FBE powder coatings, by shop application, afterwards, when the FBE powder coating became the dominant system in the pipeline coating indus-try. This article gives background on the gener-al performance of ail of these coatings and a subsequent inspection program to survey performance, focusing on FBE coating systems.Note de contenu : - PIPELINE SURVEY

Structure en nid d'abeillesIndex. décimale : 620.112 Résistance et autres propriétés des matériaux, essais non destructifs Résumé : "Pitch-catch" (low frequency) bontesters are often used in airplane maintenance to inspect honeycomb sandwich structure in situ. However, use of these instruments is often troublesome due to difficult interpretation and less-than-adequate inspection sensitivity. In this paper, new approaches for the use of low frequency bondtesters are described. Boeing developed these algorithms using theoretical work and instrumentation developed by the Commonwealth Scientific and Industrial Research Organisation (CSIRO). Use of these techniques can result in an order of magnitude increase in sensitivity. The techniques require frequency analysis, available in bondtesters such as the CSIRO "baNDIcoot", but identify settings that can be used on conventional bondtesters that display results only in the time domain.
