Cut Sheet

mils in thickness continuous over the entire length of the conduit except at

the threads, and be free of blisters, bubbles or pinholes. PVC shall be UL

listed as a primary corrosion protection.

A blue urethane coating shall be uniformly and consistently applied to the

interior of conduit. This internal coating shall be a nominal 2-mil thickness.

All male threads on elbows and nipples shall be protected by this same

application of urethane coating.

Coated couplings shall be used with coated conduit. The thickness of the

coating on couplings shall be at least equal to the thickness of the coating

on the conduit. Each coated coupling shall have a flexible PVC sleeve

which extends from each end of the coupling and which will overlap the

PVC coating on the conduit when the coupling has been installed on the

conduit. The length of the sleeve extension(s) shall be at least equivalent

to the nominal conduit size for sizes up through 2”. For sizes 2” – 6”, the

length of the sleeve extension(s) shall be at least 2 in. The PVC sleeve

shall be a nominal thickness of 40 mils in thickness. The inside diameter

of the overlapping sleeve shall be less than the outside diameter of the

PVC-coated conduit.

B. PVC COATED RIDIG ALUMINUM CONDUIT:

The PVC coated ERMC- aluminum conduit prior to coating shall be UL

listed. The PVC coated ERMC- aluminum conduit shall be UL listed with

the PVC as the primary corrosion protection.

The exterior of the conduit shall have a PVC coating of a minimum

thickness of nominal 40 mils.
