From a global perspective, many developed countries have adopted HDPE silicon core tubes as trunk protection pipelines in the laying of optical cable communication lines. From a large number of practical analyses, it has been found that the channelization of optical communication can not only improve the quality of communication and accelerate construction The speed of the communication can also e
Silicon core pipe is a new type of composite pipe with silicone solid lubricant on the inner wall. It has good sealing performance, chemical resistance and low engineering cost. It is widely used in optical cable communication network systems such as highways and railways. HDPE silicon core tube is a new type of composite pipe with silicone solid lubricant on the inner wall, referred to as silic
After the heating of the cluster tube is completed, the to-be-connected parts should be quickly disengaged from the butt-connected heating tool, and uniform external force should be applied to make it completely contact to form a uniform flange. The on-site inspection of the cluster tube shall meet the following requirements, and the tube shall be in accordance with the test report and certificate
The COD tube (corrugated fiber optic cable conduit) is made of polyethylene, and the structure uses a prism wall tube or a silicon core tube with a very low friction coefficient as a sub-tube, and a high-pressure resistant, flexible corrugated tube as a mother tube. Made. Its comprehensive performance is unmatched by any optical cable sheath tube in the past. C.O.D tube has become the best choice
How to set the pressure during production? How good is it? The pressure in the production process of the cluster tube is mainly that the vacuum pressure is generally controlled between 0.3-0.4Mpa, so as to maintain a certain water level. The steel tube or tube box is used to protect the cluster tube crossing the bridge, and the steel tube or tube box is fixed on the outside of the bridge guardrail
Precautions for construction of trenchless COD tube When the burial depth of the cluster pipe is less than 0.5m and when crossing the bridge, it is protected by C15 concrete encapsulation or galvanized steel pipe. Before laying the bundled pipes, the construction unit should consider the length of each section in the whole section, scientifically arrange the plates, do not break the pipes at wi
Advantages of COD pipe: 1. Each inner pipe of COD pipe stands tightly on the inner wall of the outer pipe during the production process. 2. The inner tube of the COD pipe is smooth and the construction is convenient. 3. The inner tube of the COD pipe is subjected to rigorous compression test in advance, and then used to produce a complete COD tube, together with the special spiral shape of the out
What is a COD tube COD stands for Corrugated Optical Duct (Corrugated OpticDuct). It is a whole composed of multiple internal cable tubes and outer tubes. Shunming COD and traditional general PVC tubes COD pass the manufactured inner tubes (3 to 5) through the reproduction process. ) The method of assembling in the outer tube has created a new era in this field.
