Pressure-opening is a safe, environmentally friendly, and cost-effective technique for the maintenance and repair of pipelines in operation. It is suitable for the routine maintenance and modification of pipelines carrying various media such as crude oil, refined oil, chemical substances, and natural gas, as well as for emergency repairs in case of accidents (such as repairs while the pipeline is under pressure, replacement of corroded sections, installation of new devices, and modifications for branching off flow). News: Yibin (We are more professional in making openings in fire protection pipes while they are under pressure). The second piece of news concerns efforts to reduce excess production capacity. Focusing on the strategies of \"reducing overcapacity, lowering costs, eliminating excess inventory, and addressing weaknesses,\" with industries such as steel and coal as key areas, local pollutant emission standards are being gradually tightened to address excess production capacity in a proactive and cautious manner. In 2017, apart from the complete shutdown of Jigang’s production capacity, the province planned to reduce its crude steel production capacity by 5.27 million tons and its pig iron production capacity by 1.75 million tons, with the aim of cutting coal consumption by 5.7 million tons. Accelerate the elimination of illegal aluminum electrolysis projects, and at the same time shut down coal-fired power plants of corresponding capacity, in an effort to reduce coal consumption by 10 million tons. By taking measures such as improving the energy efficiency of key energy-consuming devices, carrying out comprehensive reforms in coal-related industries, and making full use of green energy, the “Industrial Green Power” initiative is being advanced vigorously, with the goal of saving 36 million tons of standard coal and reducing carbon dioxide emissions by 90 million tons across the province by 2020. Let me explain the operating procedures for making openings under pressure: 1. Connect the power supply to the equipment used for making openings under pressure, turn on the motor switch, check how the device is functioning; once it’s operating properly, turn it off. 2. Attach the V-shaped bracket on the base of the pressurized hole-opening machine to the pipeline, then adjust the length of the chain and secure it in place with a pin; subsequently, tighten the nut at the other end of the chain to ensure that the machine is firmly fixed to the pipeline. 3. Determine the diameter of the hole to be drilled under pressure as specified, and install a suitable hole-drilling tool for working under pressure. 4. Start the motor and verify once again that the hole-making machine under pressure is operating properly. 5. Pull (press down) the handle of the hole-making tool under pressure to slowly lower it; as it approaches the pipe, check whether the hole‑making position is correct ； Conversely, it should be shut down, repositioned, and then turned on again. 6. When making an opening under pressure, the handle should be pressed down slowly, and the tool used for making the opening under pressure must be continuously cooled with coolant. 7. After the opening under pressure is completed, turn off the motor and remove the machine. Handle pressurized openings with care. What are the operating procedures for working on pressurized openings? Machines must not be transported on the ground. By the end of 2018, around 2,000 low-end and outdated enterprises were shut down, with 55% of these closures occurring this year. At the same time, a number of chemical enterprises were relocated, upgraded, or restructured to ensure that the efforts to reduce such enterprises yield practical results. During interviews in Wuxi, reporters learned that although the local chemical industry has undergone three rounds of rectification efforts, it still remains large in scale and numerous in number. Moreover, since most chemical enterprises started as township enterprises, the industry is naturally scattered in terms of spatial layout, which is quite far from the requirements set by the province’s \"special action\" initiatives. The office in charge of the \"special action\" in Wuxi organized various departments such as the Economic and Information Technology Commission, environmental protection agencies, transportation authorities, work safety supervision departments, and the Taihu Lake Management Office to conduct extensive investigations and research in order to study relevant policies. Pressure-based leak sealing technology is applied in many areas; when leaks occur in various systems, this technology is used to seal them up, ensuring that the leakage problem is resolved and a reliable seal is achieved. However, there are many different ways to carry out assignments; depending on the method used, the specific requirements for completing those assignments vary.
