COD cable Pipe production line makes the COD tube other name multichannel corrugated pipe, the ripple fiber optics tube protector, it is a whole which constitutes by the internal many cable ducts and the outer tube, managed COD along bright COD and traditional general PVC the inner tube which already made (3 to 5) to assemble through the reproduction process in outer tube's method founded this domain new times. The inner tube and the outer tube are (high density polyethylene) make with HDPE, have the high elasticity, although in the outer tube is equipped with the most inner tubes, still could the very good winding in entangle on the tube frame.

The resistant to compression COD product is the special spiral shape, it strengthened the traditional PE ascending pipe's resistant to compression ability, its resistant to compression ability is traditional tube's several times, enhanced the validity and the elasticity, has the earthquake, the collapse and so on, can also assure the security. Bears the chemical substance strongly, the durability, strong acidproof, alkali ability is greatly strengthened, the water resistance is more superior, lays down in the sea water and the wetland, but is anti-corrosive, is the semi-permanent pipeline.

Fiber optics, cable protection pipe and so on.
