Kinesis Pipe

Kinesis Pipes are a class of pipes from BuildCraft that transport Redstone Flux (RF). They are created by combining the original Transport Pipe with Redstone. Note that if more power is trying to go through a pipe than it can handle, a bottleneck will form and the energy "wire" inside the pipe will become red to indicate it. Befor BuildCraft 6.1.2 the pipes transports Minecraft Joules (see section BuildCraft 6.1.1 and below).

BuildCraft 6.1.1 and below
Until BuildCraft 6.1.1 the Kinesis Pipes transfer Minecraft Joules (MJ), which has been replaced in BuildCraft 6.1.2 by Redstone Flux. There is no MJ version of the Emerald Kinesis Pipe.

Below BuildCraft 3.7
In older versions, Kinesis Pipes are referred to as Conductive Pipes. Before BuidlCraft 3.70, the only Conductive (Kinesis) Pipes were Wooden, Stone and Gold ones.
