Types of Non-Metal Conduit

Most of the non-metallic conduit is crafted from a tough-sporting plastic like PVC. It is a realistic choice in areas that cannot receive metal, inclusive of a health facility MRI room. Also, it’s miles useful for encasing in concrete underneath a driveway, or regions which are frequently in contact with water. PVC conduit isn’t only watertight, but is likewise able to arise to lengthy-term publicity to water with out experiencing issues with corrosion or rust.

The preferred form of non-metal conduit is primarily based on elements like the general set up cost, corrosion resistance and mechanical protection. Here are most of the most famous types of non-metallic conduit:

Rigid non-steel conduit (RNC)

The rigid non-metal conduit is the most cost-powerful option in the market and practical for the ones operating on a decent price range. The fittings are without difficulty connected collectively with a solvent which is a lot faster than the strategies used to comfy the separate portions of steel conduit. Once the solvent is welded and cooled, the joint is positive to be watertight for the lengthy-time period. This sort of conduit may be heated to make it more pliable and without difficulty bent to healthy the awkward areas.

The widespread size of this tubing is agenda 40 or 80. There is also the choice to apply special wall thicknesses and sizes. However, the thick tubing can begin to get tough to warmness and bend, so is more realistic for the directly routes.

Even although the RNC is a flexible alternative in a selection of conditions, it does have the drawback of no longer being so powerful at standing as much as bumps or knocks in comparison to the metallic alternatives. It isn’t always a realistic preference for grounding, so a special conductor is necessary. Also, while exposed to warmness the plastic can enlarge and settlement, so should be considered when making plans the lengthy runs.

Electrical Non-metallic Tubing (ENT)

The electrical non-metallic tubing is fabricated from thin tubing like cloth this is bendy and clean bent to shape. But, the bend isn’t always probably to live permanently. This tubing is beneficial to get round barriers with no need to weld or reduce. Plus, it is brief to put in with snap-in connections, which does suggest it isn’t a realistic preference for the moist environments. The favored option for the mildly damp regions is the liquid-tight bendy non-metallic conduit which is constructed with a right seal to guard against water access.
