Pipe Factory Prefabrication To Achieve Double Benefit And Quality Improvement

In industrial construction projects, the workload of pipeline construction is large, and the amount of pipeline construction tasks has doubled, and the pipeline construction procedures are complex, and the number of components is huge. When the pipeline construction conditions are available, the construction period for pipeline installation is short, the task is heavy, and the phenomenon of time rush often occurs, which is bound to affect the quality of pipeline installation to some extent. For pipeline construction not only to ensure the quality, but also to speed up the construction progress, the promotion of factory prefabrication is the direction of engineering construction industry efforts for many years. With the rapid development of China's economic construction, the scale of engineering construction projects is becoming larger and larger, which provides development space for the factory prefabrication of pipelines in the environment. The factory prefabrication of pipeline is the direction of the development of pipeline installation projects in the future.

In developed countries, the factory prefabrication of pipelines has covered most of the building mechanical and electrical installation projects. In construction projects, there is basically no on-site prefabrication of pipelines, and more than 90% of the workload is completed in the prefabrication factory, and then gradually distributed to the site for assembly and installation according to the construction schedule. The factory prefabrication technology of pipelines has reached a fairly high level. In China, the factory prefabrication technology of industrial pipeline is basically mature, and it has been widely used in the engineering construction represented by petroleum and chemical industry. However, in civil building electromechanical engineering, the application of pipeline factory prefabrication technology is still in the initial stage of development, and needs to be further explored and promoted.

Recommendations for factory pipe prefabrication

1. Open the pipe prefabrication speed breakthrough

In order to optimize and improve the efficiency and quality of factory pipe prefabrication, it is a necessary way to open the speed breakthrough of pipe prefabrication. For example, the establishment of a special pipeline engineering company to manage the pipeline prefabrication process, the use of factory assembly line operation management mode, the implementation of process decomposition, streamlined production and other operations, and the entire process of operation supervision and management. It is necessary to establish a control system for pipeline prefabrication construction, clarify the management responsibilities of relevant personnel, improve the control means and technological level with the prefabrication process as the core, simplify the construction process and process steps, and improve the technical level of prefabrication engineers to meet the construction requirements of prefabrication and process standardization in factories. At the same time, it is necessary to control the time and space of pipeline prefabrication, promote the development and application of automatic welding, reduce the inefficient way of manual welding, and improve the efficiency of prefabrication by rail mobile distribution method. At the same time, the integration and optimization of the construction process should be strengthened, the relatively independent prefabrication sections should be established, and the quality inspection operation between each section should be set up to ensure that the overall quality of the pipeline prefabrication meets the qualified standard.

2. Strengthen the construction of prefabrication plants

In order to improve the construction efficiency of factory pipe prefabrication, project construction enterprises should strengthen the construction of prefabrication factories. The prefabrication scheme can be developed according to different prefabrication process design and production line. First of all, it is necessary to check the conditions of the factory building to see whether the factory has a standardized and standardized factory building, to provide a special place space for pipeline prefabrication, and to strengthen the supervision of the prefabrication site, and scientifically place the measures of pipeline prefabrication.

In addition, mobile workshops can be built with automated equipment to increase the flexibility of the pipeline prefabrication process.

3. New technology helps improve quality and efficiency

Innovative pipeline prefabrication technology can also improve the efficiency of pipeline prefabrication. We can improve the professional precision of pipeline prefabrication by introducing high-tech welding equipment and improving the automatic pipeline welding process independently, and then drive the progress of enterprise benefits and reputation. Through continuous innovation of prefabrication and welding technology, the results of prefabrication operations are improved. With the development of science and technology, the control of intelligent equipment and computer system should be combined to improve the process from the design of pipeline single line drawing to the second design of prefabricated pipeline drawing, establish complete information of the prefabrication process, and track the weld assembly heat treatment information and pipeline pressure test information during the whole installation process.

In summary, factory pipeline prefabrication is an important process in the construction of engineering projects. It has a better environment and equipment than the construction site, which can get rid of the restrictions brought by the environment and improve the construction speed. However, in the prefabrication process, we must first try to choose the actual prefabrication factory location and control the principle of factory pipe prefabrication. In order to improve the quality of factory pipe prefabrication, it is necessary to open the pipe prefabrication speed breakthrough, and strengthen the construction of prefabrication factories, while introducing new process technology and advanced equipment as the support for optimizing pipe prefabrication, to improve construction efficiency and bring better economic benefits to enterprises.
