3v Glass Types

3v’s primary glass is G2208 has a number of superior characteristics. In addition to its excellent corrosion resistance to acidic process environments, it is distinguished by higher thermal shock resistance and smoother surface finish than other glasses. The G2208 glass is available in: dark blue, light blue and white. The corrosion resistance for all three colours is the same.

Phi Glass is a new formula that improves the limited heat transfer properties of the glasses commonly used in the chemical industry and improves heat transfer rates across the glass interface. The glass was developed by the study of the behaviour of ceramic particles in hot and cold conditions. Phi Glass is a hybrid glass that includes a percentage of ceramic particles which impart enhanced heat transfer capacity to the glass. This glass is available in light blue colour and is the first of its type that has been introduced in the glass lining industry.

SIGMA glass is not the first of its type but it is innovative in the sense that it advances the concept of electrically conductive glass. This glass offers an enhanced electric conductivity through all layers of its lining, from the ground coat up to its last layer, thus making an electrical connection between the process fluid and the substrate. Since the introduction of SIGMA glass to the market is has become the glass preferred by the major manufacturers in central Europe and in Asia.

Glasscoat uses a unique application technology that creates a glass with a smoother surface and finer bubble structure resulting in lower air content. The lining consists of several layers applied and fired at temperatures in excess of 800 °C. The unique dust/liquid application technology allows Glasscoat to achieve the final thickness with fewer layers and trapping less air into the glass matrix. The result is a glass with a micro bubble structure and better dielectric proprieties. As proof we test all vessels at a Glasscoat standard of 30.000 V – 10.000 V to 15.000 Vhigher than the voltage used by other manufacturers in the market.

Glasscoat Engineers are familiar with European, American and Chinese pressure vessels codes, cGMP, Explosion Protection standards (ATEX and NEMA) and are familiar with the often higher technical standards of the major European customer accounts and their counterparts in the rest of the world.
