Ducting Systems
Because industrial ducting systems are very different from traditional HVAC or other types of ducting systems in a number of ways, there are special requirements that must be taken into consideration in the fabrication, installation, maintenance and repair of these systems. We at Gold Coast Refractory Service can offer experienced, comprehensive assistance with all of these areas from beginning to end.
In systems like those commonly used in many large industrial plants, duct systems used for weld fume and dust collection are under negative pressure as air is pulled at a much higher velocity through the duct, rather than pushed.
These systems are subject to much greater static pressure than is common in your average HVAC ducting. As this is the case, duct systems of this type are much more subject to abrasion from materials and dust moving through it, particularly at the areas where the air flow changes, like wyes and elbows.
What this means is, that in industrial ducting systems, significantly stronger materials are required. These strengthened materials usually begin at 28 gage steel and up, with such fittings as tees, wyes and elbows made from an even heavier gage material than the straight sections of ducting. In most cases, round is preferable to rectangular as it is much stronger structurally. Areas where joints and seams are must be properly sealed and heavily reinforced. In addition, oil mist collection systems must deal with the properties of the fluid “mist” and leaking problems that can occur at the joints and seams of the ducting structure.
Most clamp together industrial ducting systems provide a sound resolution to meet the requirements of fume, oil mist and dust collection systems. These ducts are fabricated in steels ranging from 28 gage to 10 gage in order to meet various needs.
Duct seams also can be created in a number of types, from fully welded to clinched. Joint ends are beaded and “clamped” together using gasketed clamps of stainless steel to guarantee a perfect seal. In addition, these gaskets are made from materials that best suit the application’s needs.
Of course, as is the case with most projects, proper service and maintenance of a ducting system begins with a collection of all relevant information regarding the specifics of your particular operation. Many factors such as normal operating conditions, construction materials required, space / layout limitations or requirements, cost of products and installation and perhaps many other concerns, may need to be considered. Gold Coast Refractory Service can help provide expertise in developing a plan for Refractory Duct Lining Systems that will best suit your overall situation.
