High-Density Polyethylene Silicon-Core Pipe

Silicone-core pipe is a novel composite pipeline with a silicone-based solid lubricant coating on the inner wall, offering excellent sealing performance, outstanding chemical corrosion resistance, and low construction costs. It is widely used in optical and cable communication network systems for highways, railways, and other infrastructure projects. This product is suitable for direct burial, duct installation, and trench installation, as well as for deployment within large protective conduits. Optical cables, power cables, microducts, and microduct bundles that can be installed via air-blowing within protective conduits are extensively employed in outdoor communication cabling, public information networks, cable television networks, highway communications, postal and telecommunications networks, railway communication networks, optical cable duct systems, oil and gas communication networks, and water conservancy and hydropower communication infrastructure projects.

Purpose:

Silicone-core pipe is a novel composite pipeline with a silicone-based solid lubricant coating on the inner wall, offering excellent sealing performance, outstanding chemical corrosion resistance, and low construction costs. It is widely used in optical and cable communication network systems for highways, railways, and other infrastructure projects. This product is suitable for direct burial, duct installation, and trench installation, as well as for deployment within large protective conduits. Optical cables, power cables, microducts, and microduct bundles that can be installed via air-blowing within protective conduits are extensively employed in outdoor communication cable networks, public information networks, cable television networks, highway communication systems, postal and telecommunications networks, railway communication networks, optical cable duct systems, oil and gas communication networks, and water conservancy and hydropower communication infrastructure.

Installation, transportation, loading and unloading, and storage of silicon-core pipes

1) The length of each individual reel of silicon-core pipe shall be determined in accordance with the actual project requirements and the spacing between manholes. During the installation of silicon-core pipe, within the trench (over long distances),
There will be a certain natural curvature, so the actual length of the silicon-core pipe used is typically 0.4% to 0.7% longer than the ground length; a typical allowance of 1.3% is generally adopted. If this factor is ignored, it will result in an increased number of short sections and joints.
2) Transportation of silicon-core pipes: During loading, no large gaps should be left between adjacent reels to minimize mutual impact among the reel racks during transit; fully wound silicon-core pipes must not be transported in a horizontal position. Secure the reel racks to the vehicle body with heavy-duty ropes, and place triangular wooden chocks beneath and on both sides of the reel racks to prevent the fully wound pipes from rolling around inside the cargo compartment during transport. Never use ropes to tightly constrict the pipes, and it is strictly prohibited to lash silicon-core pipes with iron wire or steel cable.
3) Handling of silicon-core pipes: There are typically three methods for handling:
(1) When loading and unloading with a forklift, ensure that the steel forks do not come into contact with the silicon-core pipe; the forks must enter only from both sides of the rack to prevent damage to the pipe.
(2) When loading and unloading with a crane, the wire rope may be passed through the central axle hole of the reel stand or the upper end of the steel frame for lifting; under no circumstances shall the silicon-core pipe be lifted directly by looping the wire rope around it. When lowering, the pipe must be placed gently on a level surface.
(3) The channel steel shall be laid diagonally across the rear of the cargo compartment; when the reel rack is pushed downward from the compartment, personnel on both sides must use thick ropes to wrap around the vehicle’s gantry and lower it slowly. It is strictly prohibited to directly push the silicon-core pipe down from the cargo compartment or from any elevated position.
4) Storage and Preservation of Silicon-Core Ducts: During storage, silicon-core ducts shall be neatly arranged in rows according to color codes, with the end caps on both ends of each duct kept intact to prevent rainwater, sand, dust, debris, and other foreign materials from entering the duct. Silicon-core ducts must be stored away from sources of ignition, and conspicuous no-fire signs shall be posted at the storage area.
