Where metal conduits cannot be used, other materials are preferred. The most common among them is the Polyvinyl chloride (PVC)conduit. Polyvinyl chloride (PVC) is a combination of plastic and vinyl that is used to make PVC pipes. These popular types of pipes are commonly used in plumbing as an alternative to more expensive copper piping. PVC is also used to produce electrical conduit. PVC conduit wiring is usually used where it will be in contact with water, such as below ground or encased in concrete.
PVC conduit will not rust or corrode when exposed to water. They can withstand high temperatures and are fire resistant. They are also shock proof. They are easy to cut and join and hence installation of PVC conduits are quite easy. They are lightweight and inexpensive and are versatile as they come in a variety of thickness. PVC Electrical Conduit Pipes are available in sizes of 20mm, 25mm, 32mm, 40mm, 50mm, & 63mm with mechanical strength of Light (LMS ), Medium(MMS), Heavy(HMS) series as per IS:9537 (Part-3) : 1983 standards. These pipes are available in standard length of 3 mtrs.
Since PVC is resistant to weather, chemicals, corrosion, shock and abrasion, it is has become the preferred electrical pipe choice for most long-life and outdoor projects. PVC material has been extensively tested, and their use and properties monitored since they were invented. On the basis of these many tests, they were deemed safe and their extensive use was authorized.
Schedule 40 PVC conduit is permitted for exposed locations where they will not be subject to physical damage. Schedule 80 PVC conduit is identified for use in areas subject to physical damage. PVC conduit installed underground must comply with the various burial requirements that is applicable.
Hence PVC conduits meets a host of different needs and have a wide variety of applications.
