Galvanized rigid conduit (GRC) is galvanized steel tubing, with a tubing wall that is thick enough to allow it to be threaded. Its common applications are in commercial and industrial construction. [1] It is designed to protect wire and connectors. Intermediate metal conduit (IMC) is a steel tubing heavier than EMT but lighter than RMC. It may ...
Bend radius, which is measured to the inside curvature, is the minimum radius one can bend a pipe, tube, sheet, cable or hose without kinking it, damaging it, or shortening its life. The smaller the bend radius, the greater the material flexibility (as the radius of curvature decreases , the curvature increases ).
PVC Bendit was designed in late 2010 to early 2011 as a way to bend longer sections of pipe than were possible with other methods. The inventor, Victor Johnson of Manitou Springs, Colorado, was looking for a method to bend long sticks of clear PVC to make a lighting system, and he could not find a method to efficiently bend more than two feet of pipe at a time.
The profile is guided between bending-roll and supporting-roll(s), while being pushed through the tools. The position of the forming-roll defines the bending radius. The bending point is the tangent-point between tube and bending-roll. To change the bending plane, the pusher rotates the tube around its longitudinal axis.

A compression fitting 15 mm isolating valve. A compression fitting is a fitting used in plumbing and electrical conduit systems to join two tubes or thin-walled pipes together. . In instances where two pipes made of dissimilar materials are to be joined (most commonly PVC and copper), the fittings will be made of one or more compatible materials appropriate for the connect
Bending A chimney starter, a sample product of bending. Bending is a manufacturing process that produces a V-shape, U-shape, or channel shape along a straight axis in ductile materials, most commonly sheet metal. [1] Commonly used equipment include box and pan brakes, brake presses, and other specialized machine presses.
Plenum-rated and riser-rated cables are restricted to only allow certain chemicals for manufacture of the wire insulation and cable sheath. Typically this results in reduced flexibility of plastic cables, making it stiff and hard to bend. The bend radius may also be increased, and tight bends can potentially crack or tear the insulation and ...
