Equipment produces three-, five-layer composite pipe

THE Machines Yvonand SA offers composite pipe production lines for three- and five-layer construction. The equipment can be supplied in metal-plastic, plastic-metal, and plastic-metal-plastic configurations.

All current alloys are employed, from aluminum to steel, as well as copper alloys and polymers such as PA, PBTP, fluoropolymers, and all current polyolefins. Typical production speed in a continuous 24/7 operation for a five-layer composite construction with a 0.63-in. dia. is 196.85 FPM.

After forming and welding, the metal tube can be passed directly through an inline annealing oven and exposed to temperatures of about 1,832 degrees F. This technology also is available during the manufacture of high-precision monolayer alloy tubes such as those found in heat-exchanger pipes.
