Microduct HDPE Tube Introduction
HDPE bundle pipes are generally ring-shaped pipes formed by combining multiple micro-pipes. During the construction process, it is necessary to dig enough pits for installing pipes, and cooperate with fixing brackets and other mechanisms to fix the pipes and then backfill them. Due to the use of ring pipes, It makes it inconvenient to install and fix the pipe itself. In the case of using a fixed bracket, the size of the pit that needs to be excavated is much larger than the actual size used, and the space utilization rate is low, which greatly prolongs the entire construction time of excavation and backfilling, which affects the construction. progress, but also caused unnecessary damage to the environment.
HDPE Tube Characteristics
1. Wide range of applications: direct burial, pipelines, overhead, buildings; especially in complex terrain conditions, it is more space-saving; such as building line wells, bridges, crossing roads, railways, rivers, etc.;
2. Wide applicable temperature range: -60~70CO, construction temperature -10~40CO;
3. Long service life: non-sunlight exposure, more than 50 years;
4. The unit length is large, and there is no interface within a well spacing of 1000m, so there is no worry about water ingress, and the follow-up construction is simple;
5. The whole system is fully sealed, with good waterproof performance; and there are three layers of sheath (outer tube, aluminum foil, core tube) to enhance the mechanical protection of the optical cable; at the same time, the aluminum foil has a shielding effect;
6. Each core tube is an independent unit, which does not affect each other and is easy to maintain;
7. Due to the good flexibility of the pipeline, it can bend and undulate freely, and effectively resist the damage to the pipeline and cable caused by the foundation settlement; 8. The fiber optic cable is laid by the air blowing method, which has high construction efficiency and safer fiber optic cable;
8. The optical cable laid into the duct by air blowing should be relaxed relative to the optical cable laid into the duct by traction, which can protect the optical cable from short-term and high tension and effectively prolong the service life of the optical cable.
Application Scope
1. Long-distance backbone network
2. Metropolitan area network – a computer communication network established within a city
3. Wide area network – a computer communication network established in a vast area (beyond the city)
4. Local area network – a computer communication network established within a local area (such as a school, an enterprise…)
5. Private network——internal communication network established by public security, railway, forest area, sports venues, etc.
6. Public network – a communication network established by the telecommunications department to provide various communication services to the public
7. Local network——in a long-distance numbering area, several end offices, inter-office relays, Changshi relays, and subscriber lines
8. Personal network – communication between users’ homes, offices or personal information appliances (the basis of Bluetooth technology)
During the construction of the cluster tubes, the number of pre-buried holes is increased, the construction speed is improved, and the material and construction costs of the engineering unit are greatly reduced. The color of the five-hole cluster tube is uniform, and the color is mostly red, but other colors can also be customized according to user requirements. The bundled pipes are smooth and flat, with uniform color, and defects such as deformation and twisting are not allowed. Cracks, breakage and perforation are not allowed on the inner and outer pipe walls. Markings should be durable and legible. Bundle tubes are mainly suitable for: protection of telecommunication cables in railways, China Unicom, China Telecom, China Netcom and other places. PVC cluster tube is a plum blossom-shaped communication tube formed by pvc particles as the main material and other formulas through a unique mold, also known as cluster tube and honeycomb tube. The inner wall of this tube is smooth and can directly pass through optical cables, saving It has reasonable structure, high use value and long service life.
The porous structure allows various types of cables to be inserted in different holes. These holes are separated from each other and do not interfere with each other, and a lot of spare holes can be reserved, which provides a great degree of convenience for the future addition of equipment and line transformation and timely restoration of operation after failure. The material of the bundle tube is mainly PVC. The bundle tube of this material has very strong toughness, which is very convenient during construction and can be applied to various construction methods. It greatly reduces the cost and reduces the damage and impact of the surrounding environment. Therefore, the use of cluster tubes is very good in these industries. Industries such as electric power and network communications cannot do without cluster tubes.
