Million-ton ethylene compressor solution passed
Thread protectors are devices used to protect the threads of pipes, valves, and other threaded components during storage, transportation, and handling. They are typically made of plastic or metal, and are designed to fit over the threaded end of the component, providing a protective barrier.

The domesticization of large-scale ethylene compressors is still the first case in China. When the National Development and Reform Commission approved Fushun Petrochemical's ethylene project, it put forward localization requirements for ethylene compressors. At the demonstration meeting, after discussion and review of the technical plan, the expert group unanimously held that the localization of the Fushun petrochemical million-ton ethylene engineering ethylene compressor unit will fill domestic gaps, break the monopoly of foreign technologies, save construction investment, and improve the manufacturing of major technical equipment in China. The capability and technical level are of great significance. After years of hard work, Shengu and Hangzhou Steam Turbine solved many key technologies in the development of the ethylene compressor unit through independent development and cooperative manufacturing, and accumulated experience in the design and manufacture of ethylene compressor units. It basically has the conditions to achieve localization and bears the manufacturing capacity of Fushun's 1 million-ton ethylene engineering ethylene compressor unit; the selection and structure design of low-temperature materials, the welding of impellers, and the rotor assembly process, the calculation and control of the turbine flow passage As for key links and technologies, Shengu and Hangzhou steam turbines must be taken seriously so that the performance parameters of the compressor group meet the technological and production requirements, and the vibration amplitude of the mechanical operation meets international standards to ensure the long-term stable operation of the unit and reach the international level of similar products. In the process of localization of the project, It is necessary to specify the drum set as the unit of the unit and to implement the responsibility, and to strengthen the assembly and quality control of the auxiliary machine and supporting system.
According to reports, the National Development and Reform Commission approved in March 2006 the construction of a million-ton-class ethylene project at Fushun Petrochemical. At the same time, it clearly defined the project as a localization support project and required the domestically-built million-ton ethylene “three machines†as petrochemicals. The breakthrough in the localization of equipment is provided by Fushun Petrochemical, which is responsible for the first set of localization tasks for ethylene refrigeration compressors, and large-scale cracking furnaces, ethylene cold boxes, and spare parts for the rotors of the “three machines†are also resolved domestically.
Thread protectors serve several purposes. Firstly, they prevent damage to the threads, which can occur from impacts, scratches, or corrosion. Damaged threads can lead to leaks, reduced performance, or even complete failure of the component. By using thread protectors, the threads are shielded from potential harm, ensuring their integrity and longevity.
Additionally, thread protectors help to keep dirt, dust, and other contaminants out of the threads. This is particularly important in industries such as oil and gas, where threaded components are often exposed to harsh environments. By keeping the threads clean and free from debris, thread protectors help to maintain the performance and reliability of the components.
Thread protectors come in various sizes and designs to fit different types of threaded components. Some are simple caps that cover the threads, while Others may have additional features such as handles or lifting devices for easier installation and removal. They can be reusable or disposable, depending on the specific application and requirements.
In summary, thread protectors play a crucial role in preserving the integrity and performance of threaded components. By providing a protective barrier and keeping the threads clean, they help to prevent damage, ensure proper functioning, and extend the lifespan of the components.
