The construction technical process of pipeline with pressure sealing is a necessary technology to ensure the stability of modern industrial and agricultural production, which is mainly used in industrial production or urban pipeline network maintenance, transformation and accident emergency treatment. The following is a detailed process for this technology.

1. Check the environment and engineering facilities of the construction site, understand the structure and use of the pipeline, and formulate a detailed construction plan.

2. At the same time of formulating the construction plan, carry out stability evaluation, confirm the job responsibilities of the on-site operators, and arrange personnel allocation and management. Ensure that all personnel have sufficient stability awareness and necessary skills.

3. Prepare the required materials and equipment, such as pipe plugs, pressure gauges, valves, pipe plugs, and protective appliances. Ensure that the quality and quantity of materials and equipment comply with the relevant stability standards and engineering standards.

4. Carry out drainage and exhaust treatment of the pipeline, and remove the dirt in the pipe to facilitate the subsequent construction efficiency.

5. Close the corresponding inlet valve, input clean air into the pipeline, check the leakage resistance of the pipeline through the pressure gauge and ensure the stability of the operator.

6. Under the monitoring of the pressure gauge, place the pipe plug in an appropriate position, determine the installation position, and check whether the installation quality meets the requirements to avoid air leakage.

7. Fill the slow water pump or air pump through the pipe stopper to gradually increase the pressure. After reaching the predetermined pressure, check the leakage resistance of the pipeline through the pressure gauge to ensure safety.

8. After confirming that the pressure at the pipe plug reaches the required level, retain onsite personnel to avoid accidents.

9. Monitor the operating point of the leaked pressure. If the pressure drops, apply the pressure gauge to locate the leak point in order to carry out necessary maintenance treatment.

10. After the completion of construction, remove the pipe stopper, and carry out the corresponding cleaning and maintenance to facilitate the next use and extend the service life.

The above is the construction technical process of pipeline with pressure sealing, which is becoming more and more important for modern production and social security. In the use and construction, we should strictly follow the standard process to ensure the stability, efficiency and quality of construction.
