【China Railway Qingdao World Expo City】Metal Hose Contract
Shanghai Songjiang Shock Absorber Group Co., Ltd. official website introduces the contract information for metal hoses in China Railway Qingdao World Expo City. Songjiang Group provides metal hoses for numerous projects. The following is a detailed introduction of the metal hoses provided for China Railway Qingdao World Expo City.
1.Introduction to China Railway Qingdao World Expo City: China Railway Qingdao World Expo City is located in Jiaonan, Huangdao, Qingdao City. It is constructed by China Railway Real Estate Group Co., Ltd., with a total construction area of 800,000 square meters and a total land area of 2,000,000 square meters. The residential complex comprises 3,555 households. The property management company for the community is China Railway First Group Taiping Property Management Co., Ltd., Qingdao Branch of Beijing China Railway First Taiping Property Service Co., Ltd. In 2021, after review and approval by the Administrative Committee of the Global Association of the Exhibition Industry (UFI), China Railway Qingdao World Expo City, located in the West Coast New Area of Qingdao, officially became a UFI-certified exhibition venue.
Qingdao World Expo City, driven by the conference and exhibition industry and tourism, is constructing a large-scale exhibition complex integrating various formats, including exhibitions, conferences, hotels, commerce, and offices. It has become a crucial hub for industry-city integration and innovative development, listed in the major project library for the transformation of new and old kinetic energy in Shandong Province and as a key project in Qingdao. Qingdao World Expo City is a new international landmark in Qingdao, with an investment of approximately 50 billion by China Railway, making it the largest investment project of China Railway nationwide. The project, combined with the permanent site of the East Asian Ocean Cooperation Platform, aims to create a world-class living circle integrating functions such as culture, tourism, leisure, entertainment, and business residence. The current development and construction of Qingdao World Expo City represent a significant effort by China Railway Real Estate in practicing industry and comprehensive urban operation, providing strong support for the country’s strategic construction. Entrusting China Railway Real Estate with the development of the ninth national new area, facing Northeast Asia and even the whole world, reflects the government’s firm determination for the development of the West Coast. The transition from the Qingdao city center to the Qingdao World Expo City project truly achieves the shift from the skyline to the coastline.

3.Introduction to the Use of Metal Hoses in China Railway Qingdao World Expo City
This contract mainly includes several products: outdoor buried corrugated compensators, stainless steel metal hoses, corrugated compensators, and stainless steel corrugated pipes.
Introduction to Outdoor Buried Corrugated Compensator:
The buried corrugated compensator is suitable for pipelines with only axial displacement. This product has the ability to compensate for lateral displacement and axial and lateral synthesized displacement. However, due to its small compensation amount, it is generally used for axial compensation to better leverage its characteristics, providing a longer service life and greater safety and reliability.
The buried corrugated compensator (also known as a buried compensator) is mainly used for axial compensation of buried pipelines. It has bending resistance, so the impact of pipeline sinking can be disregarded. The product has the characteristics of large compensation amount and long service life. Axial compensation range: 30mm-500mm
The buried corrugated compensator consists of one or more corrugated pipes connected together. The corrugated pipe has an outer sleeve that allows axial movement of the corrugated pipe. This outer sleeve serves as both a protective device and maintains stability.
Introduction to Stainless Steel Metal Hose:
The corrugated tube of the hose is formed by high-precision plastic processing of ultra-thin-walled seamless or multi-welded stainless steel pipes. The elasticity and flexibility of the hose are determined by the profile of the corrugated tube, providing good flexibility and fatigue resistance. This makes it easy to absorb various cyclic loads caused by movement and deformation, especially in pipeline systems with the ability to compensate for large displacements. In addition to our original sophisticated equipment for hose production, in 1998, we introduced two high-precision, high-tech corrugated tube automatic welding production lines, greatly improving the quality of the hose and removing length restrictions, meeting the needs for extra-long hoses.
The mesh sleeve is the main pressure-bearing component when the hose is installed in a pressure pipeline. It also provides protection for the corrugated tube. Depending on the pressure in the pipeline and the application environment, one or more layers of stainless steel wire or steel strips can be selected for weaving.
Since the main material for making hoses is austenitic stainless steel, it ensures excellent temperature resistance and corrosion resistance. The working temperature range of the hose is -196-600°C. The stainless steel grade used in the hose is selected based on the corrosiveness of the medium in the pipeline, ensuring the corrosion resistance of the hose.
Corrugated metal hoses have many advantages such as good flexibility, fatigue resistance, high temperature resistance, resistance to high and low temperatures, and corrosion resistance. Compared to other hoses (rubber, plastic hoses), they have a much longer service life, thus offering higher comprehensive economic benefits. With the development of modern industry, there is an increasing demand for corrugated metal hoses with high temperature and high-pressure resistance.
Application scope of hoses: Used for conveying pipes that require sufficient flexibility, piping at places prone to vibration, and for various mediums such as steam, gas, air, heavy oil, petroleum, and chemical products.
