Boiler Gaskets Still Big Business

Boilers are closed vessels in water heating, it is important but the name might be misleading; the water does not have to actually boil. The hot water is then used for heating purposes such as hot water showers, central warming, cooking and power generation. With the effects of global warming, climate conditions have changed, winters are longer, and the cold lasts long after the snow is gone. Since boilers serve multiple purposes and are cheaper than other methods, their demand has remained relatively steady.

The biggest culprit in the breakdown of a boiler is a faulty gasket. Made from a variety of elements; Topog-E rubber, ceramic fiber, copper, and plastic being the main ones. The demand for gaskets has grown with the rise in demand for automation, used in most everyday appliances to offer protection from vibration, electromagnetic interference; gaskets form a perfect seal for parts that have an imperfect fit. With technology evolving rapidly, people are increasingly going for custom gaskets and companies like Die & Gasket in Phoenix, Arizona, specializing in the creation of high-quality gaskets using different elements.

Throughout history, boilers have been used with a difference being in the fuel used from firewood, coal to natural gas. No matter what kind of boiler being used (Pot Boiler, Flued Boiler, Fire-tube or Water Tube.) all boiler have one thing in common, they all need gaskets. These gaskets not only form seals, but they also separate sheets of different elements used to insulate against excess hot air. Boiler gaskets need to make top covers that can withstand the hot steam of up to 1200o Fahrenheit (650o Centigrade), but other factors also contribute to the choice of a gasket.

Boilers boil up water, and this results in various changes in states and the changes affect different elements in different ways. The seals in boilers are exposed to creep, hot/cold fluctuations, high pressures and chemicals used in water treatment. Depending on the environment that will be encountered, gaskets made out of cutting out the shape from the desired element. Depending on the budget, purpose and the likelihood of chemical contact, gaskets can be made into many designs.

The most basic gaskets are known as Sheet Gaskets, these are crude and cheap and are made by punching out the gasket shape on an iron element , historically asbestos was used but now the elements most preferred are from various forms of rubber. Solid material gaskets are made from various metals, these are better than the iron properties gaskets but come with the risk of oxidation, and they have to be softer than the parts being closed up. The most common type of boiler gasket are Spiral-Wound gaskets, and these are made by with a mix of a metallic element and a filler material. The two are wound such that the metal and filler element alternate with one beginning from one end and the other from the opposite side. The filler elements acts as the seal while the metallic element were offering structural support.

Boilers have various connections and with these come Flange Gaskets. These are gaskets that fit between two flared pipes to provide a higher surface area. They are categorized according to their internal and external diameters. Rope or hemp is used to act as connectors in joints made of pipes that have undergone cutting.

Boiler Gasket Selection

To minimize downtime, it’s important to select the correct boiler gasket to ensure trouble free service. To provide ease of install and replacement, boiler gaskets should be selected and based on performance.
