Single-hole microtube are the most basic components of the micro-piping system. They are high-density polyethylene (HDPE) as the main raw material. Generally, the plastic pipe with the nominal diameter of not more than 16mm can be understood as the smaller size silicon core tube. The inner wall of the pipe also has a continuous production of extruded permanent solid silicon core lubrication layer, part of the specifications of the micro tube wall with a longitudinal guide rib structure, further reducing the friction coefficient of the inner wall of the pipeline to facilitate the laying of fiber optic cable.

The basic performance parameters microtube:
