Carbon tube, also known as "carbon threaded protective sleeve," is a type of power embedded conduit. It is a single-wall spiral pipe primarily made from HDPE high-density polyethylene resin, along with modified carbon and other auxiliary materials, produced through special extrusion and molding processes. With its unique spiral structure, carbon corrugated pipe boasts numerous advantages, including high strength, high toughness, corrosion resistance, high-temperature resistance, high insulation resistance, excellent flame retardancy, lightweight, long service life, and resistance to deformation.
This carbon corrugated pipe is widely used in urban street lighting cable burial projects, the laying of power and communication cables for electrified railways, the construction and renovation of power and communication facilities on highways, residential community construction projects, and underground cable projects in parks and large entertainment venues. It is the most ideal protective conduit for buried cables.
Product Features
1. Excellent flexibility: The pipe features a unique spiral design, allowing it to bend freely around obstacles, making construction convenient.

2. Long single-piece length: The length of a single piece can be customized according to user requirements, reducing the number of connections and enabling faster construction and easier maintenance.
3. Lightweight: It is lighter than cement short pipes, fixed-length cast iron pipes, steel pipes, and fixed-length PVC pipes, making it easy to transport and handle.
4. High strength: The unique spiral physical structure provides high compressive strength, ensuring it does not deform underground under heavy pressure.
5. Corrosion resistance: It offers excellent resistance to acids, salts, and alkalis, with a service life of over 50 years.
6. Safety: It has strong impact resistance, flexibility, and high strength, ensuring safety even in the event of earthquakes or ground subsidence.
7. Easy cable pulling: The smooth inner and outer surfaces have a low friction coefficient, and the pipe is equipped with a pulling wire, making cable installation very convenient.
8. Low construction costs: Combining the above advantages, carbon corrugated pipe enables fast construction, short project duration, and fewer connections, offering high economic benefits.
