It is composed of porous thin-walled micro-tubules and thin-sheathed layers. It is suitable for non-long-term pressure-bearing applications, such as piercing in other pipes or residential roads.
Cluster tube
It is composed of porous thin-walled microtubules with thick outer sheath, which is suitable for complex road conditions or potential long-term pressure-bearing applications, such as long-distance trunk lines, metropolitan area network trunk lines, etc.
C Exhaust focusing tube
It is composed of porous thick wall micro tubes and thin sheathing layer coated on the outer layer. The shape is like row type, which is suitable for the construction of pavement slotted mode.
D Parallel Cluster Tube
It is composed of porous thick wall microtubules and thin sheathing layer coated on the outer layer. The shape is like juxtaposition, which is suitable for the construction of pavement slotted construction.
