1. Quality control in the installation process
The actual installation of the boiler pipe is not carried out on the flat ground. This also causes the installation of the pipe and bracket to have a direct impact on the extension of the pipeline and accuracy of the pipeline connection. Therefore, in the process of installing pipes and brackets, it is necessary to fully consider the problems that may occur, and appropriately adjust the brackets and pipes to avoid them.
Moreover, when the bracket and pipe are installed, the details of installation should be paid attention to. Ensure the pipe body, spring and components of connection points have the same model numbers. In the welding of specific boiler tubes, the welding is also susceptible to environmental impacts due to the relatively complicated welding process and high technical requirements. Therefore, in the actual welding process, the welding personnel should reasonably adjust the various parameters of the welding process based on the welding materials and standard process parameters, and adjust the construction drawings in time according to the conditions of the construction site environment. Before the actual welding operation, the aircraft must be cleaned up in advance to effectively ensure the welding quality. In the actual installation process of the boiler pipeline, it is also necessary to make specific plans in advance for the installation location, process, personnel, and possible deformation during later use. At the same time, the space required for the pipeline's installation should be reserved in advance around the boiler to ensure the quality of the boiler tube's installation.
2. Strengthening the inspection of the installation quality of boiler tubes in power plants
The installation quality of boiler tubes is directly related to the stable operation of the boiler after it is put into use. Therefore, in the installation process of the boiler tube, it is necessary to ensure the scientificity of the installation to ensure the service life and safe operation of the boiler system. Once a problem occurs for the boiler tube, there will be serious consequences. Therefore, after installing the boiler tube, an inspection must be done before it is put into use to ensure its installation quality. In addition, after the boiler pipeline is put into use, inspections are also required from time to time to find out and deal with problems in time to ensure the safe operation of the boiler.
Paying attention to the initial self-inspection of boiler tubes
Before the water pressure test of the steel furnace system is carried out, it is advisable to implement the initial self-inspection of the boiler tube, mainly to check the quality problems of each component to ensure the accuracy of the installation position of each component, and the firmness of the installation. Check the differences between the construction site and construction drawings. After the self-inspection is completed, necessary maintenance is required before the water pressure test can be carried out to determine the pressure bearing capacity of the pipeline. In the specific test process, data such as water consumption and test time need to be calculated strictly.
Strengthening the self-inspection of boiler tube pressure vessels
The self-inspection carried out for boiler pipeline pressure vessels is essentially a test for the practicability of boiler pipeline pressure vessels. For the boiler tube pressure vessel, only when its pressure is lower than that brought by the pipe body, the gas in the pipe can maintain normal circulation, so that the boiler tube can exert its actual effect. In the self-inspection process, the pressure and sealing effect of the pipeline pressure vessel can be tested. During the specific self-inspection, the certification of materials such as piping materials, equipment and safety accessories should be reviewed to ensure the quality of the materials.
Inspection of installation quality of boiler pipeline pressure vessels and pressure pipelines
Before putting the boiler tube into use, it is necessary to completely inspect the installation quality of the pressure vessel and pressure pipe, which is also the last inspection step. In the specific inspection, it doesn't simply monitor the boiler tube. It is necessary to implement the duties to specific individuals, and check the engineering certification materials. In the specific inspection process, once a lack of procedures or incomplete procedures occur, records and follow-up work must be done. The boiler tubes can only be put into use when all inspections are conducted.
3. Matters needing attention during installation
Since the installation of steel furnace pipes is complicated, some quality defects and common problems are difficult to be avoided. Therefore, it is necessary to pay attention to the actual work to ensure that the installation quality meets the standard requirements. When installing boiler tubes, carefully check the pipe fittings, accessories and valves to ensure that their appearance is in a good condition and conforms to the requirements of the pipe's installation standards. At the same time, it is necessary to clean up the inside of the pipeline and valve, and no debris is allowed inside. When welding pipes, the distance between the welding position and starting point of the elbow should be greater than the outer diameter of the pipe, and that between the two butt welding seams of the pipe must also be greater than the outer diameter of the pipe. Carefully inspect the valve when it is installed to ensure that it has no quality problems. At the same time, after the valve core and valve seat are ground and colored, the tightness of the joint must be ensured between the two. The pressing force of the valve flange must be uniform. Before the valve is installed, a pressure test should be carried out for 1.25 times the actual working pressure of the valve. The installation can be carried out only after the test is qualified. During the specific installation, the installation direction should be determined according to the flow direction of the medium or the sealing direction. The cleaning should be done and keep the tube closed.
4. Conclusion
A boiler is very important production equipment in power plants. In the boiler system, steel furnace pipes have the function of transmission and connecting, which can effectively ensure the safe operation of the boiler and realize the safe operation of the power plant as a whole. Therefore, attention needs to be paid to the installation of steel furnace pipes. There are strict requirements for the installation of steel furnace pipes, especially the meticulousness of the installation process. In the actual installation process of the boiler pipeline, any small problem will have a serious impact on the stable operation of the boiler in the later period. Therefore, boiler installers are required to have professional skills to ensure the scientific installation of steel furnace pipes. At the same time, before the pipeline is put into use, it is necessary to do a good job of inspection, find hidden dangers in time, reduce the risk factor of the boiler pipeline after it is put into use, ensure the safe and stable operation of the boiler, and lay a solid foundation for the timely and reliable supply of electrical energy.
