PEJacking PipeFeatures include aging resistance, impact resistance, and pressure resistance; it can prevent the generation of eddy currents during the laying of high-voltage cables, reduce transmission energy consumption, and prevent the pipe material from overheating.PEPipe Jacking is suitable for pipe jacking construction, reduces excavation volume, causes minimal disturbance to the ground surface and strata, and is effective for complex geological conditions. Pipes can bend with the terrain and navigate around obstructions, enhancing construction efficiency.
1. Physical properties: Made from polyethylene, offering excellent rigidity, strength, and flexibility, which is beneficial for pipeline installation.
2. The PE power cable protective conduit has a long service life.
3. High-toughness PE pipes offer excellent flexibility and bendability. They have a elongation at break exceeding 500%, making them highly adaptable to uneven ground settlement and misalignment. They also possess good seismic resistance, and small-diameter pipes can be bent to any desired shape.
4. PE power cable protection pipe features smooth closure, low friction coefficient, easy to pull through cables, and shortened construction duration.
5. PE power cable protective conduit offers excellent electrical insulation properties and has a long service life (over 50 years for buried piping).
6. PE power cable protection pipes are lightweight, easy to maintain, install, and handle, and are convenient for transportation and operation.
7. Small-diameter tubing can be supplied in coil form, featuring longer sections and fewer joints for easy installation.
8. Tubing can be manufactured in various colors for easy identification.
9. Low Temperature Impact Resistance - The low-temperature brittleness temperature of the ***PE is low, allowing safe use within a temperature range of -20 to 40 degrees.
10. Compared to other metal piping, PE piping is four times as strong.
A variety of construction methods.PE pipes can be installed using various trenchless techniques, in addition to the traditional excavation methods, such as jacking, lining, and bursting methods. This is an ideal choice for locations where excavation is not permitted.
Product Application:
Gas, liquefied gas, and natural gas transmission pipelines; liquid transport pipelines for industries such as chemical fibers, food, chemicals, forestry, dyeing and printing; telecommunications lines, power cable protection pipes; agricultural irrigation pipelines.
Installation Method for PE Corridor Ceiling Pipe
Hydraulic expansion and pneumatic hammers utilize expanders to enter the soil layer. Simultaneously, new pipes are pulled in to replace the old ones. This method, using the pneumatic hammer to provide expansion force, is known as the pipe bursting technique.
2. This method is applicable to undamaged pipes. Insert a smaller new pipe into the old pipe. This method is known as the lining method.
3. Suitable for large lake and river crossing projects, this method involves using pilot holes along the drilling trajectory, while reaming the hole, to guide the pipeline into the钻孔. This is known as the drilling-in method.
