Single-Hole Microtube

The most basic component of the micro-pipe system is high density polyethylene(HDPE plastic pipe,which can be simply described as “small-sized silicon core pipe”)with a nominal outer diameter of not more than 16mm,The inner wall of the pipe has a permanent solid silicon core lubricating layer, and some specifications of micro-longitudinal guide rib groove structure on the inner wall of the micro-pipe can further reduce the friction between the inner wall of the pipe and the cable, which is beneficial to the laying of optical cables by air blowing. A variey of microtubes can be selected by customers. The most commonly used specifications include Ø10/8mm,Ø12/9mm,Ø14/10mm.

Cluster Tube

In the bundle pipe, porous microtubes are arranged and combined according to a certain way,and the outer layer is coated with polyethylene sheathe to form the bundle pipe, so that more tube holes can be accommodated in a limited space. The bundled microtubes are independent of each other,which is convenient for the identification and connection of microtubes. The outer layer sheath provides better mechanical lightness for the microtubes.

Product Characteristics

1. The inner wall of microtube never falls off, and friction coefficient is very small,so it is very easy for optical cable to be extracted in the pipeline.

2. The radius of curvature of microtube is small ( ten times of its outer diameter). When laying, the bends and drops are encountered, which can be determined according to the topography of Hanjing, without any treatment, let alone setting up excessive wells.

3. The length of each microtube (disc) can be made into any length. Generally, considering transportation safety and construction blow-out technology,the standard length of each microtube(disc) is set at 200M.

4. The background color and color bar of microtubeles can be determined according to the actual situation of the project. To enhance the antixidant capacity of microtubules, we recommend using microtubules with air guide grooves on the inner wall of white ground. This kind of micro-plastic pipe can prolong its service life, and can also effectively divide trenches and lay multiple pipe, such as white, blue,yellow,red and orange.
