Abstract
An easy pull conduit for receipt of wire and/or wire bundles reduces the resistance to pulling wire and/or wire bundles. The conduit has an inner surface and a boron nitride coating applied to the inner surface. An aluminum EMT conduit having the boron nitride coating exhibits a 55 percent reduction in pull force compared to a bare aluminum conduit. A method for reducing the pull force required to pull wire and/or wire bundles through a conduit is also disclosed.
Claims13
A conduit for receipt of wire and/or wire bundles, the conduit having reduced resistance to pulling wire and/or wire bundles, comprising:
- a conduit having an inner surface;
- and
- a boron nitride coating applied in a carrier to the inner surface, wherein the boron nitride is present in a concentration of at least 85% by weight in the carrier.
A method for reducing the pull force required to pull wire and/or wire bundles through a conduit, comprising:
- providing a conduit having applied to an inner surface thereof boron nitride, wherein the boron nitride is applied in a carrier and wherein the boron nitride is present in a concentration of at least 85% by weight in the carrier;
- and
- pulling a wire or wire bundle through the conduit.
