Electrical conduit that is made of metal, such as steel or aluminium, is known as metal conduit. Compared to other conduit materials like PVC or plastic, metal conduit is more robust and long-lasting. Additionally, it is more resistant to dangers like fire.
A common option for a variety of applications is metal conduit, including:
commercial structures
industrial settings
installations made outside
Locations at risk
The Benefits of Metal Conduit
In comparison to other forms of conduit, metal conduit has a number of benefits, such as:
Durability: Compared to other conduit types, metal conduit is stronger and more resilient. It is corrosion, impact, and crushing resistant.
Metal conduit has a high fire resistance. High temperatures and flames can be applied to it without melting or burning it.
EMI shielding: Metal conduit can offer EMI shielding, which aids in preventing electromagnetic interference from damaging electrical lines.
Grounding: Grounding electrical connections with metal conduit can help shield humans and equipment from electric shock.
Amount of Metal Conduit Use
Because of its durability, fire resistance, EMI shielding, and grounding characteristics, metal conduit is a popular choice for a multitude of applications. In addition to being reasonably priced, metal conduit is an economical option for many applications.
Various Uses for Metal Conduit
There are numerous uses for metal conduit, such as:
Commercial structures: To shield EMI and safeguard electrical lines in commercial structures, metal conduit is employed.
Industrial facilities: EMI shielding and environmental protection for electrical cables are provided in industrial facilities via the use of metal conduit.
Outdoor installations: To shield electrical lines from the elements and damage from people or animals, outdoor installations employ metal conduit.
Hazardous areas: To protect electrical wires from fire and explosions in hazardous areas like chemical facilities and petrochemical refineries, metal conduit is utilised.
Metal Conduit Types
Metal conduit is available in a wide range of forms, including:
Metal conduit: The most used kind of metal conduit is rigid metal conduit. It is built of sturdy metal and is corrosion, impact, and crushing resistant.
The construction of flexible metal conduit consists of a thin metal tube covered by a flexible metal sheath. Although it is simpler to bend and install, flexible metal conduit is less resilient than stiff metal conduit.
Metal tube covered in a liquid-tight sheath makes up a liquid-tight metal conduit. Metal conduit that is liquid-tight is impervious to liquids like water and oil.
The Best Metal Conduit to Use
The following criteria should be taken into account when selecting metal conduit:
Application type: The kind of metal conduit required depends on the application type. For applications where durability is crucial, rigid metal conduit is the ideal option, whereas flexible metal conduit is the best option for applications where flexibility is crucial.
Environment: The type of metal conduit required will depend on the environment in which it will be installed. For applications where the metal conduit will be exposed to water or other liquids, for instance, liquidtight metal conduit is the ideal option.
Budget: The budget should be taken into account when selecting metal conduit. Flexible metal conduit is less expensive than rigid metal conduit, which is the most expensive kind of metal conduit.
Setting up Metal Conduit
There are numerous ways to install metal conduit, including:
Using a pipe threader, metal conduit can be threaded. Then couplings are used to join threaded metal conduit.
Compression fittings: Compression fittings are another way to join metal conduit. Although compression fittings are less robust than threaded fittings, they are simpler to install.
Set screw fittings: Metal conduit can also be connected using set screw fittings. Set screw fittings are more resilient than compression fittings, but installation is more challenging.
Conclusion
Electrical conduit made of metal is a flexible and reliable material utilised in a range of applications. In comparison to other conduit types, metal conduit has a variety of benefits, such as durability, fire resistance, EMI shielding, and grounding abilities. In addition to being reasonably priced, metal conduit is an economical option for many applications.
It is crucial to take the type of application, the climate, and the budget into account while selecting metal conduit. There are numerous ways to install metal conduit, including threading, compression fittings, and set screw fittings.
