When carrying out the leakage plugging work of natural gas pipeline equipment, the pressure-operated plugging operation technology should be used reasonably. Here, it is also necessary to have a sound operation and planning scheme. Effective implementation at work. There is a certain level of reliability in this. In petrochemical production pipeline equipment, natural gas is often flammable and explosive. Therefore, it needs to be very strictly regulated. First, it should be judged reasonably. Among them, the reason for the leak in the pipeline should be started. It is necessary to integrate the specific conditions of natural gas leakage. If it is in accordance with the mode of depressurization treatment, under the corresponding condition mode, the welding leakage can be reasonably carried out. At the same time, a comprehensive analysis of temperature and leakage area should also be carried out. Second, we should pay attention to the environment of the leak point, starting from the wind and wind direction, to prevent the problem of gas accumulation. However, if there is an indoor leak, it should be ventilated, the combustible gas should be discharged, and safety hazards such as fire should be prevented. Third, positive pressure should be used when welding. Starting from the specific welding process, there should be a gas source inside the system and professional personnel should be responsible for it. The problem of negative pressure cannot occur in it. The gas pressure mainly involves the range of 200-450mm. If it does not meet this range, the fire should be stopped.
Safety precautions for hot workers: First, welding workers should have professional skills and knowledge, and must have certificates for employment. Second, the action staff should proceed from specific standards and strictly implement the operation techniques. Third, the staff should start from the upper air outlet of the welding and pull the protective equipment to prevent safety problems. Fourth, in response to possible problems, we should estimate them and optimize the emergency handling mode. Fifth, guardians should clarify their responsibilities and improve their technical level. In this process, the situation on the spot should also be dealt with. Under the circumstance of paying attention to various safety matters, it can be concretely implemented and reasonably deal with unexpected dangers.
