Emergency plan for heat transfer oil leaks and detailed procedures for welding repairs at pipeline leaks

May I ask if you are utilizing the waste heat from the riser? Is heat transfer oil used as the heat exchange medium? ? How is things progressing currently? Could we exchange some experiences? ?

With such high residual heat in the rising pipe, it’s not suitable to use heat transfer oil as a heat transfer medium, right?

Japan’s earliest technology used heat transfer oil as a heat exchange medium! !

Have you guys tried it? Which factory do you come from, and how is the performance? Could you introduce it?

The full name of pressure-based leak sealing is “rapid pressure-based leak sealing without shutting down the pipeline or container and without the need for welding.” It has now become a standard practice in this field. This industry focuses on addressing issues related to corrosion, perforations, leaks, and other problems in various pipelines and containers used in industries such as petroleum, refining, ethylene production, chlor-alkali manufacturing, gas processing, chemicals, power generation, papermaking, shipbuilding, as well as in residential settings. It can effectively solve various challenges that arise during production processes； Applicable media: oil, water, gas, steam, various gases, sulfur, concentrated acids, alkalis, highly corrosive substances such as benzene, and various chemicals. Principle of leak sealing: The technology of leak sealing under pressure (online sealing) originated in the UK. In China, this technique has been used for stopping leaks while the system is still in operation since 1984. Today, it is widely applied in power and chemical industries, serving as an important means for ensuring long-term operation without leaks. Moreover, avoiding the need to shut down the system to discharge materials not only brings significant economic benefits to enterprises but also has important environmental advantages. Pressure-based leak sealing usually requires the fabrication and installation of clamps, after which a specialized glue injection tool is used to inject the dedicated pressure-based leak sealing adhesive into these clamps, thereby creating a dense filler that forms a new seal. When performing leak sealing under pressure, operations that generate sparks such as welding and electric grinding wheels can often be used, as there is no concept of working without fire in leak sealing under pressure. However, in actual leak sealing operations, flammable and explosive substances are often present, and such substances must not generate any sparks at all. As a result, in China, pressure-based leak sealing methods were gradually replaced by methods that allow sealing under pressure without using fire. This approach makes it possible to explain the essence of this industry more clearly. Yet people tend to simplify it to just \"pressure-based leak sealing.\" Today, when people talk about pressure-based leak sealing, they actually mean \"sealing under pressure without using fire.\" Since the industry of leak sealing under pressure has not been standardized, there are various terms used to describe it. Most people consider leak sealing under pressure to be a form of injection-based sealing, but in reality, injection-based sealing is just one of the techniques employed in this field. It can only be used for leak sealing on straight pipes, which limits its applicability; it is ineffective in cases involving tees, elbows, reducers, flange roots, and large containers. Methods for sealing leaks include adjustment-based sealing, mechanical sealing, support methods, compression methods, clamp methods, glanding methods, packing methods, covering methods, tensioning methods, plugging methods to seal holes, sewing methods, wedge insertion methods, plug usage methods, and welding repair methods. It is recommended to use a specialized plasticized composite sealing adhesive; its main advantage lies in the fact that it replaces traditional gluing methods, allowing for significant resource savings. These sealing methods are flexible, enabling safe, efficient, and rapid leak sealing in most hazardous areas ； If the pipes and equipment already have conditions for pressure release, operations can be carried out directly. For those parts where it is not possible to stop the operation or release pressure, special clamps can be used to block the leaks first and then carry out repairs; these clamps can be reused, thus saving labor and materials. For leakages in straight pipes, the pipe leak-sealing clamp developed by our company can be used for one-time repairs, which also helps to increase the strength of the pipes.
