Pipeline with pressure opening is an important method for construction and maintenance in pipeline system. It can be operated while the pipeline is running, without having to shut down the pipeline system, saving time and cost. However, the construction of pipeline with pressure opening also has certain risks and requirements, which need to strictly abide by the operating procedures and stability standards. In this paper, the requirements of pipeline construction with pressure holes will be elaborated to ensure the stability and construction quality of the project.

First of all, before the construction of pipeline with pressure opening, it is necessary to carry out adequate construction preparation work. The construction unit shall conduct a comprehensive inspection and evaluation of the project site, confirm the parameters such as material, pressure and temperature of the pipeline, and check whether the surrounding environment meets the construction requirements. At the same time, the construction unit shall prepare the necessary construction equipment and tools, including opening equipment, stability protection tools, etc., and carry out the necessary training and guidance for the construction personnel to ensure that they have the skills and knowledge required for opening operations.

Secondly, in the construction of pipeline with pressure opening, the construction unit must strictly abide by the relevant construction norms and standards. Before opening the hole, the pipe should be adequately decompressed to ensure that the pressure inside the pipe is reduced to the range. During the opening process, the construction personnel should operate in accordance with the regulations to avoid too large opening speed and too high opening pressure to prevent the pipeline from bursting or leaking. At the same time, the construction unit shall be equipped with advanced monitoring equipment to monitor the pressure and temperature changes of the pipeline in real time, find problems in time and take measures to deal with them.

In addition, when the pipeline is constructed with a pressure opening, the construction unit should pay attention to the implementation of stability measures. At the opening site, a warning line and stable signs should be set up to limit the entry of non-construction personnel, and to keep the site clean and tidy. Construction personnel shall wear safety protective equipment that meets the requirements, such as hats, shoes, gloves, etc., to ensure the personal safety of construction personnel. At the same time, the construction unit should also formulate emergency plans and tight aid measures to deal with possible accidents and ensure the smooth progress of the construction process.

Finally, after the construction of pipeline with pressure holes is completed, the construction unit should carry out comprehensive acceptance and monitoring work. Check and test the opening parts to confirm whether the position, size and quality of the opening holes meet the requirements. At the same time, the pipeline system is comprehensively tested and monitored to ensure the normal operation and stability of the pipeline system. In addition, the construction unit should also develop sound construction records and reports to record the key parameters and data in the construction process to provide a reference for future maintenance and management.

In general, the construction of pipeline with pressure opening is a complex and important engineering activity, which requires the construction unit to have rich experience and technology, strictly abide by the relevant norms and standards, and strictly implement stability measures to ensure the stability and quality of the project. In this way, the normal operation of the pipeline system can be guaranteed and the smooth progress of the project can be guaranteed.
