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.
COD tube, collecting tube, micro tube collecting tube, COD collecting tube The flexible bellows is a mother tube, which is formed by compound extrusion. COD pipe has the following advantages: 1. During the production process, the inner tubes of the COD cluster tube stand tightly on the inner wall of the outer tube. 2. The inner tube of COD bundle pipe is smooth and easy to construct. 3. The in
COD pipe equipment, COD fiber optic cable protection equipment, COD corrugated pipe equipment. The English name of COD is CORRUGATED OPTIC FIBER, and the Chinese translation is called multi-channel corrugated tube and corrugated optical cable protection tube. It is made of HDPE (high-density polyethylene) resin by extrusion molding. It has a high degree of elasticity. The structure is a pipeline p
