A conductive flange is set forth for a fitting such as a conduit. The flange is non-conductive including at least one strand of conductive yarn in conductive contact with the conduit and extending to the flange rim where it intersects one or several bolt holes. The flange is conductively attached to the conduit such that any static electrical charges are conducted by the yarn to the ounting bolt or bolts disposed in the bolt holes. The bolts are grounded to, in turn, ground the static charge and prevent sparking.

Conductive flanges for pipe fittings

An insulated pipe for conducting high and low temperature fluids includes a rigid carrier pipe, a layer of volumetrically compressible insulating material around the O.D. of the carrier pipe, and a protective outer pipe around the insulating layer. The method of making the pipe product includes placing a closed flexible bag around the carrier pipe and the insulating layer, and then drawing a vacuum on the interior of the bag to compress the insulating layer. The outer pipe is slid lengthwise over the compressed insulating layer, and the vacuum is then removed to allow the insulation to partially expand and fill the annulus between the carrier pipe and the outer pipe.
