Glass Tube - Pegasus GlassThe glass mixture used to make Glass Tubes is typically made up of silicate materials with the potential for additives during the process. A stream of air keeps the molten glass from collapsing until it has hardened in the shape of a tube. As glass is a brittle material, it is necessary for glass products to undergo the process of annealing after they have been fabricated, especially in the manufacturing of heat resistant glass.
Annealing reheats and cools the glass which removes any potential areas of stress or weakness and makes the glass product more resistant to sensitivity to temperature changes. Glass tubes are hollow and are available in a variety of thicknesses and lengths. Depending on the intended application of the glass tube, the wall thickness can be adjusted accordingly. Tempered glass or safety glass tubes are likely to be thicker.
Glass Tube - Pegasus GlassAs glass is a malleable material when heated, it is possible for glass tubing to be bent or curved although this is likely to distort the cross section of the tubing. Yet the added malleability broadens the range of possible uses for glass tubes and rods. These hollow or solid stock size tubes have a number of uses including fluorescent or halogen light bulbs, sterilized tubes used for medical and laboratory purposes as well as for vials, gas transportation and material storage.
In industrial applications glass tubing is commonly used with liquids and gases to store, transport and in flow measuring applications, or in specific components of mechanical pieces such as sight glass. There are many things to consider when selecting the most suitable glass rod for a process. For example, a tube's optical properties and thermal capabilities, as well as physical and electrical characteristics.
If a tube is to be used for lighting or visual purposes, its levels of opaqueness and resistance to light are important. If a tube or rod is to undergo stress or tension in its application, then wall thickness and material strength should be considered. Density, thermal conductivity and co-efficiency, as well as electrical resistance and loss tangent for energy are further considerations, especially in precision applications such as medical operations.
