If the tubing is bent infrequently after installation, refer to table 360.24 (a) in the nec®. Note normally the pipe body is built up as a composite structure composed of metallic and polymer layers. The parts that make up the entire lfmc are bound with water.
Galvanized metal flexible conduit YouTube
Which is used for the required seal fitting includes a plastic coating.
Deflection is limited to 2 percent if the flexible pipe has a rigid lining and coating and 3 percent for a rigid lining and flexible coating.
If the tubing is bent for installation, use table 360.24 (b) in the nec®. Typical flexible hoses metallic flexible hoses are available in various end connections like welded pipe end, flanged end, threaded ends, tube ends, coupling ends, etc to meet a broad range of application requirements.

Flexible metal conduit has a spiral construction which allows the conduit to bend easily, simplifying installation in walls or other structures. Flexible metal conduit and fittings flexible metal conduit also known as fmc, this conduit offers the crush resistance of metal combined with flexibility to handle bends in tight spaces.
This strip is formed into a corrugated profile and is tightly interlocked to form a.
You find this used most often for fixture whips, motor attachments to safety switches, and other short run connections where a flexible system is more suitable than a rigid pipe system.
