Generally, the plastic corrugated pipe manufacturers is roll with 25 meters, 50 meters or 100 meters long. 

How can such a long pipe pass through the wire and cable harness?

A buyer said: I cut it and then feed wire harness inside. This is really a method, but if the wire used is long, it can't be cut into pieces.

B buyers said: feed the wire harness to pipe directly. this is another method,but it may cause blocked in the pipeline.

tell you the most convenient way to feed wire harness to pipes:

1. Insert a relatively thin and thin steel wire into the plastic corrugated pipe, and tie the steel to the pipe and then pass it through.

2. split the corrugaetd pipe from one side. The professional saying is “splitting”. You can also order the spliting corrugated pipe machine directly, and the machine will spit the corrugaed pipe to feed wire harness.  Although this method is simple, however it is only suitable for places that do not come into liquids, and is not waterproof,not oil resistant.
