Description
marker
Carbon pipe is a new type of single-wall spiral power cable protection pipe made by special extrusion molding and unique rotational molding technology. It is made of HDPE high density polyethylene as the main material, and modified carbon and other auxiliary materials. Excellent chemical properties, good insulation, stress resistance, good strength and corrosion resistance, acid and alkali corrosion resistance and long service life.
KEYUACE-HDPE carbon pipe with its unique progressive filamentary physical structure provides pressure resistance and impact resistance far exceeding the technical standard GB/T13381.9, and also has good flexibility and self-healing properties. Light weight, high strength, corrosion resistance, arbitrary length, free bending and traction steel wire laid inside the pipe make construction quick and easy to maintain. It has excellent indestructibility, does not come into contact with oxygen in the absence of sunlight, and has a service life of more than 50 years when buried underground.
Functions:
1. Good flexibility. The product is shaped like a special thread and can bend freely around obstacles, making the design convenient.
2. The length of one root is large. The length of one root is determined by the user as desired to reduce the number of joints, making construction quick and easy to maintain.
3. Light weight: shorter than cement pipes, fixed length cast iron pipes, steel pipes and fixed length PVC pipes are lightweight, easy to carry and reduce labor intensity.
4. High strength. The special thread-like shape of the product provides high compressive strength and does not deform due to strong pressure underground.
5. Corrosion resistance. The product has excellent resistance to acids, salts and alkalis and has a long service life.
6. Safety: The product has high impact resistance, anti-interference and high toughness. It is safe even in the event of changes such as earthquakes or subsidence.
7. Convenient thread: the inner and outer surfaces of the product are smooth, the friction coefficient is small. There is a wire inside the tube, which makes threading very convenient.
8. High Reliability: The products have been carefully tested and identified by relevant national departments, and they all meet technical standards. They are reliable substitutes.
9. Low construction cost. Due to the above advantages, construction is fast, the construction period is short, interfaces are few, and it has high economic benefits.

Special Note: Related specifications, models and production technical parameters, including product wall thickness and quality improvement, can also be customized according to customer needs.
Construction method:
1.Choosing the diameter of carbon pipe (threaded carbon pipe, single wall spiral pipe, carbon corrugated pipe, black spiral pipe)
Select according to cable outer diameter, voltage, current and other project conditions.
2. Digging engineering trenches
The trench must be excavated in accordance with applicable department regulations and user requirements. Its width and depth should be determined depending on the number of cables laid. The distance between the tube and the trench is 50 mm, and the distance between the pipe and the tube is 30 mm.
3. Laying
After placing the carbon pipe in the trench, areas with large bends must be sealed with cement to prevent them from becoming tangled or crushed. The connection between two sheathing pipes must be laid with bricks, and the heads of the sheathing pipes must be secured with cement.
4. Connection
If two carbon pipes need to be joined end to end, first screw the joint to the joined end, then screw it to the other joined end, and then wrap with PVC sealing tape or use special KEYUACE carbon pipe joints to make the connection. .
5. Backfill
After laying the carbon pipe as required, simply backfill it with the original soil from the trench and compact the backfill soil.
