With the rapid development of urban planning and construction, the steel mesh skeleton composite pipe has been widely used in various construction projects for a long time, and its many advantages have been recognized by us. In order to make better use of it, let's take a look at the precautions when assembling the steel mesh skeleton composite pipe.
Before laying the steel wire mesh skeleton composite pipe, check the pipe material. If cracks, gouges or scratches are found, check the pipe material. Upper repair welding. If there is no reason for repair welding at first, repair welding shall be carried out when obvious symbol operating conditions are made on the pipeline. Pipeline prefabrication shall be carried out according to the double track diagram of pipeline management system, and pipeline components shall be selected according to the number and rules of the double track diagram. The number of pipeline management system and the number of each component shall be stated together according to the prefabrication order.
The squeezed pipes can be prefabricated on the ground in the principle of pipe support being close to each other. If it is necessary to expand equipment one by one on the pipe gallery, the pipes must be scattered during pipe laying, instead of being stacked on a structure or pipe gallery in a centralized way. After the pipes are laid into the trench, they should be laid along the axis of the trench without great distortion or bending, The multiple pipes connected on the trench can be lowered into the trench after being fully cooled.
The support and bracket shall not be changed and adjusted when the steel mesh framework is used to replace the pipe equipment. The equipment shall be flat and firm, and the design elevation shall meet the preparation requirements. The middle of the pipe and the pipe support must be padded with rubber, and the support and bracket shall be closely connected with the steel pipe. When laying underground, the pipe can be placed in the trench for assembly and welding, and the support can be placed horizontally on the trench, Place the pipe inside to prefabricate the assembly equipment.
Before the pipeline equipment, the pipe fittings and pipes should be placed according to the rules of engineering construction I preparation. The direction of placement should be conducive to assembly and welding. Buried pipes should also be conducive to hoisting and lowering into the trench. The squeezed pipes should also be conducive to hoisting and threading. When laying pipes, the middle of the pipe fittings should be connected head to tail persistently. When laying flange coil pipes, attention should be paid to the positive and negative excitation of the sealing groove of the flange coil head. The lifting and placing of pipes must avoid hazards. Ensure light lifting and small handling). You cannot drag on the ground. Pay attention to safety when lifting pipes.
