        3. Guigang Iron and Steel Group was established in March 2003, succeeding the Guangxi Guixian Iron and Steel Works founded in 1958. With over 50 years of steel production history, it is a privately-owned integrated iron and steel enterprise encompassing ironmaking, steelmaking, and rolling operations. The company occupies a site exceeding 1 million square metres, with principal products including HRB400(E) φ12-40mm hot-rolled ribbed steel bars, Q195-270 φ16-40mm hot-rolled smooth steel bars, HPB300 φ5.5-16mm coiled bars, and HRB400(E) φ5.5-16mm coiled threads. Since its inception, the company has pursued high-level development through substantial technical upgrades funded by capital investment. Its current equipment standards are advanced, featuring a 1080m³ blast furnace for ironmaking, a 120-tonne converter for steelmaking, and rolling systems comparable to those in China's 10-million-tonne-scale steel enterprises. The company now possesses an annual production capacity of 3.2 million tonnes of steel, generating an annual output value exceeding RMB 10 billion and contributing over RMB 1.5 billion in profits and taxes. It stands as a key enterprise and major taxpayer in Guigang City, Guangxi, recognised as one of Guangxi's Outstanding Enterprises and among the Top 100 Enterprises in Guangxi.
4. Guigang Iron & Steel Group prioritises environmental governance and resource utilisation, consistently treating the development of a circular economy and enhanced environmental protection as major strategic tasks in fulfilling social responsibilities and implementing the Scientific Outlook on Development. Environmental improvements are undertaken concurrently with technological upgrades, ensuring comprehensive recycling of waste heat, residual pressure, waste gas, wastewater, iron-bearing materials, and solid waste. The enterprise has now achieved waste heat power generation from blast furnaces and converters, processing and recovery of slag and steel slag, desulphurisation of sintering flue gas, circulating wastewater to achieve zero discharge of effluent and slag, while ensuring exhaust emissions meet regulatory standards. During the Twelfth Five-Year Plan period, Guigang Steel Group will steadfastly adhere to the Scientific Outlook on Development, resolutely advancing technological and managerial innovation.

        Introduction to Shanghai Luoying Expansion Joints Adopted by Guangxi Guigang Iron & Steel Group: Luoying expansion joints are commonly referred to as expansion joints or flexible connectors. They comprise a corrugated tube (an elastic element) as the primary working component, supplemented by end tubes, brackets, flanges, guide tubes, and other accessories. As a compensating element, it utilises the effective expansion and contraction of its corrugated tube to absorb dimensional changes in pipelines, ducts, or vessels caused by thermal expansion and contraction. It also compensates for axial, lateral, and angular displacements in such systems. Additionally, it serves to reduce noise and vibration, finding extensive application in modern industry. In heating systems, expansion joints are installed on pipelines to prevent deformation or failure caused by thermal elongation or temperature stresses during heating. They compensate for thermal expansion, thereby reducing wall stresses and forces exerted on valves or support structures.
