A gasket is a mechanical seal that bridges the gap between two and more joining surfaces. These gaskets work well in preventing leakage under stress and strain from joined objects. For the implementation of gaskets, they require mating surfaces on machine parts and fills the defects properly. Excessive or inadequate gasket tension is a prevalent issue due to varied heat exchanger models. Large gaskets produce insufficient pressure, and hence it is essential to use the short gasket. Appropriate gaskets offer improved seating friction and sealing as well. Based on their dimensions and measuring tension, it is possible to repair most seating stress-poor heat, exchangers. Due to excessive stress, it is essential to add many bolts which may harm the graphite sealing. Here, one can select the bolts with optimum width and even change them.
What is the heat exchanger gasket?
Heat exchanger gaskets are available in several models based on the sort of heat exchanger and its application. One can use the metal jacketed, cam profile, and plate type of heat exchanger gaskets for simplicity. Along with this, each type of gasket has numerous configurations. Several companies manufacture a wide range of gaskets, including shell, tube, plate, and frame heat exchangers gaskets. These gaskets are useful in operations involving steam generation and heating or cooling processes.
What is the suitable material for Heat Exchanger Gasket?
To fabricate tube and shell exchanger gaskets, one can use a soft, resilient material shrouded with metal. The selected material provides additional mechanical strength. Metal clad gaskets are applied frequently in combination with narrow flanges. The combination produces a robust and resilient gasket that can be useful in complex shapes
Types of gasket materials
Several gasket materials are available and known for their consistency and measurements. Variety of materials are available for the production of gaskets, and its list includes the following:
For the manufacturing of rubber gaskets, natural rubber is useful, but nowadays synthetic rubber is preferred.
Graphite foil gaskets
The graphite foil consists of around 100% laminated graphite, enabling smooth handling and giving power to metal.
Fibre jointing compressed asbestos gaskets
It is a ubiquitous material suitable for low-pressure applications.
Manufacturing of Metal Jacketed Heat Exchanger Gaskets
Metal jacketed heat exchanger gasket is one of the suitable gaskets in heat exchanger operations. It is useful in circular and non-circular format and available in standard and non-standard sizes. For these gaskets’ production, various standards are suitable that include API, ANSI, DIN, and BS standards. The operating conditions and the mechanical features of the flanged assembly decide the style of gasket and metal. Besides, these gaskets are available in a custom format based on operational specifications. Metal jacketed heat exchanger gaskets are fabricated to fit in and offer an efficient seal.
Key Features of Heat Exchanger Gaskets
Heat Exchanger Gaskets are available in the custom form to give accurate and smooth assembly of gasket obstruction bars into the tube sheet channels. Additionally, weld-in bar exchanger gaskets allow advantages over one-piece gaskets with complete bars and a long sealing life. They have bars seal separately from the outer ring. All the heat exchanger gaskets are available in customized designs following API 601 for ANSI B 16.5 and API 605.
