【Delong Steel (Thailand) 550 Hot Rolled Strip Molten Steel System Rubber Expansion Joint】 information. Songjiang Group provides rubber expansion joints for many steel enterprises. Below is an introduction to the Delong (Thailand) 550 hot rolled strip molten steel system rubber expansion joints.
I. Successful Commissioning of Delong Steel Thailand 550 Hot Rolled Strip Molten Steel System: The Delong (Thailand) 550 hot rolled strip molten steel system project, EPC contracted by Qinhuangdao Institute of China Metallurgical Oriental Engineering Co., Ltd. (CMOEC), was successfully commissioned on July 30, 2015, and passed the acceptance of the owner’s project department. The successful commissioning of the water system created favorable conditions for the subsequent full-line hot test of the hot rolled strip production line and was unanimously affirmed and praised by the owner’s project department. The Delong (Thailand) 550 hot rolled strip project is located in the Thai-Chinese Rayong Industrial Zone in Thailand and is an important strategic deployment by Delong Group in response to the national policy of “going global” by investing in overseas steel plants. This project is the first overseas EPC project directly contracted with the owner by the Qinhuangdao Institute, involving new topics such as sea transportation, customs declaration, and tax rebate, which is of milestone significance for Qinhuangdao Institute in exploring overseas markets. In the face of many difficulties and unknown risk factors of the project, in order to ensure the smooth progress of equipment supply, Qinhuangdao Institute specially established the Delong (Thailand) Water System Equipment Supply Project Department, with President Sun Ling personally serving as the project supervisor, and appointed special personnel responsible for the implementation, procurement, finance, technology, and on-site work of the project. From the signing of the contract, design, equipment procurement, customs declaration and shipment to the successful commissioning of the equipment, the project condenses the efforts and hard work of the leaders, project department, and designers at all levels of the Qinhuangdao Institute. In the face of the severe situation of overcapacity in the domestic metallurgical market, it has become a consensus among Chinese steel entrepreneurs to “go global” and lay out overseas. The successful operation of the Delong (Thailand) hot rolled strip molten steel system equipment supply project by the Qinhuangdao Institute of China Metallurgical Oriental Engineering Co., Ltd. not only accumulated valuable experience in the operation of foreign supply projects but also played a positive role in expanding the foreign metallurgical market.
II. Introduction of 【Delong Steel Thailand 550 Hot Rolled Strip】Molten Steel System Rubber Expansion Joint: Songjiang Group’s rubber expansion joints are fabric-reinforced rubber parts with flat joints. They are a type of pipeline joint with high elasticity, high air tightness, medium resistance, and weather resistance.
Classification:

- 1.6MPa
- 2.5MPa
- 4.0MPa
Performance Characteristics:
- Small size, light weight, good elasticity, easy installation, and maintenance.
- It can produce lateral, axial, and angular displacement during installation, without being restricted by the non-concentricity of the pipeline and the non-parallelism of the flange.
- It can reduce the noise transmitted by the structure during work, and has strong vibration absorption ability.
Rubber expansion joints are widely used in water supply, drainage, sewage treatment, petroleum, chemical industry, installation, construction, and many other industries. The products are sold well in more than 20 provinces, cities, autonomous regions, and municipalities across the country, and have been unanimously praised by the majority of users.
Detailed Applications of Rubber Expansion Joints in Molten Steel Systems:
- Sealing of Pipeline Connections: Rubber expansion joints effectively seal pipeline connections, preventing leaks of water, steam, or other fluids. This ensures the integrity and safety of the pipeline system, which is critical in a molten steel system where fluid containment is essential to maintain operational safety and efficiency.
- Absorption of Vibration and Shock: In steel mills, machinery and pipelines are subject to significant vibrations and shocks due to the operation of heavy machinery and the flow of molten steel. Rubber expansion joints have the elasticity to absorb these vibrations and shocks, thereby reducing the risk of pipeline damage and enhancing the lifespan of the system.
- Adaptation to Thermal Expansion and Contraction: The temperature variations in a steel plant can be extreme, especially in the molten steel system. Rubber expansion joints can accommodate the expansion and contraction of pipelines caused by these temperature changes. This adaptability helps in maintaining the pipeline’s structural integrity and prevents joint failure due to thermal stress.
- Ease of Installation and Maintenance: The compact and lightweight design of rubber expansion joints makes them easy to install and maintain. Their flexibility allows for minor misalignments during installation, reducing the need for precise alignment and easing the installation process in complex piping systems.
- Reduction of Noise Transmission: By absorbing vibrations, rubber expansion joints also reduce the transmission of noise through the pipeline system. This contributes to a safer and more comfortable working environment in the steel plant.
Application of Shanghai Songjiang Group’s Rubber Expansion Joints in Delong (Thailand) 550 Hot Rolled Strip Molten Steel System Project:
The DN1200 rubber expansion joints provided by Shanghai Jiuhu have been successfully applied in the Delong (Thailand) 550 hot rolled strip molten steel system project after rigorous field testing and verification. These joints played a crucial role in ensuring the sealing of pipeline connections, absorbing vibrations and shocks, adapting to temperature changes, and maintaining the overall integrity and safety of the molten steel system. Their reliable performance has been integral to the successful operation and production of the hot rolled strip line.
Conclusion:
Rubber expansion joints produced by Shanghai Songjiang Group are essential components in molten steel system projects. They ensure the normal operation of pipeline systems and enhance the safety and stability of the working environment. With their reliable quality and excellent performance, these rubber expansion joints have made a positive contribution to the successful commissioning and operation of the Delong (Thailand) 550 hot rolled strip molten steel system project, exemplifying the importance of high-quality joint solutions in industrial applications.
