Salt Mist Chamber

Salt Mist Chamber

Salt spray test is also called as Fog Test. This is an accelerated environmental corrosion test in which metal specimens are exposed either continuously or intermittently to a fine mist of salt-water solution used to evaluate the resistance to corrosion of paints, coatings, or electrical connections. The appearance of corrosion products (oxides) is evaluated after a period of time. Test duration depends of the corrosion resistance of the coating; the more corrosion resistant the coating is, the longer the period in testing without showing signs of corrosion.In the salt spray test cabinet painted coated panels, automobile components i.e Electro-plated, Painted, and Anodized etc are exposed to a mist of salt over a period of test duration. Saturated air produced by spraying common salt solution into an enclosed cabinet creates humid atmosphere upto 98%. The articles being positioned for this accelerated corrosion test in such a way that they are exposed to the hot mist produced in the chamber, through the controlled air and liquid nozzles. The instrument is suitable for testing as per IS BS ASTM standards. Testing is carried out at 35 deg cent. Or even upto 50 deg cent.

Wet Film Wheels

Wet Film Wheels

Caltech Engineering Services Mumbai India Wet Film Wheels are rolled via thumb wheel specially made from brass on the flat surface to measure wet film thickness of the wet painted surfaces. The wet film wheel gauge is in the form of a wheel, approximately 50mm in diameter, grooved with three disk sections. Ends sides of the disks are of the same diameter, uniformly spaced apart for gauge support, and are concentric. Centre grooved third disk is smaller, and is eccentric to them. When the wet film wheel gauge is rolled over a wet film, center eccentric disk will also roll on the surface to pick up the material only at and below the actual thickness, which permits its immediate and direct reading. These are used for accurately measuring the wet film thickness of paints, primers, inks, adhesives, gel coatings and several other products. The Wet Film Wheel has engraved scale on the side face of measuring rim. The gauge is highly accurate with disadvantage of wft range. Wet film wheel has low range of measurement; therefore it is often used while close range measurements are required.

DGVG Equipment DCVG

The voltage gradient becomes larger and more concentrated the greater the current flowing and the closer you are to a coating fault location. In general, the larger the fault, the greater the current flow and hence bigger the voltage gradient. The direct current voltage gradient method (DCVG) uses a sensitive mili-volt meter, to indicate the potential difference between two coppercopper sulphate half cells placed in the soil in the voltage gradient at ground level. If spaced two metres apart in a voltage gradient, one half cell will adopt a more positive potential than the other, which thus enables the size of the gradient and direction of the current flow causing the voltage gradient to be established.

All of these findings can take place without the necessity of uncovering the pipeline under test. However, a Pearson-Type Detector can be used successfully only if a pipeline has been carefully backfilled and the soil is compact around it. There also must be some moisture content in the surrounding soil. The cleats are worn by two inspectors walking in tandem. The cleats are terminated by cable connections to a receiver worn on the belt of one inspector. They enable him to accurately find holidays or large discontinuities in pipe coatings.
