Shanghai Songjiang Shock Absorber Group Co., Ltd. has published the key information of the rubber joint contract for the [Phase I Clean Energy Demonstration Project of Changchun Nanxi Zhirong Project] on its official website. As a leading enterprise in the industry, Songjiang Group has been providing high – quality rubber joints for urban clean energy projects for a long time. Its products are of reliable quality and worthy of trust.
I. Rubber Joints: High – Quality Materials and Excellent Performance
(I) Materials and Manufacturing Processes
The rubber joints of Songjiang Group are made of pure natural rubber without any recycled rubber, ensuring high elasticity, wear resistance, and aging resistance of the rubber. The flange materials are carbon steel flanges or galvanized flanges, which have good corrosion resistance and high strength, effectively guaranteeing the sealing and stability of the connection between the joints and the pipelines. During the production process, advanced manufacturing techniques are strictly followed. Through multiple processes such as precise mold forming and high – temperature vulcanization, the dimensional accuracy and physical properties of each rubber joint meet high – standard requirements.
(II) Vibration Isolation Advantages
The rubber joint vibration isolators play a crucial role in this project. They can effectively isolate the vibration and noise generated during the operation of air – source heat pump equipment and pipeline systems. The unique rubber structure can absorb and buffer vibration energy, reducing the impact of vibration on the building structure and the surrounding environment. By reducing the vibration transmission rate, it can effectively prevent structural fatigue and damage caused by vibration and extend the service life of equipment and pipelines. At the same time, the significant noise – reduction effect can create a quiet and comfortable environment for the project area and improve the overall user experience.
II. Overview of the Phase I Clean Energy Demonstration Project of Nanxi Zhirong Project
The Changchun Municipal Planning and Natural Resources Bureau has announced the adjustment of the engineering plan for the Phase I of the Nanxi Zhirong Project. The project is located east of Renmin Street and next to Changchun No. 2 Experimental Middle School. The Phase I covers a planned area of 55,900 square meters, with a total construction area of 164,000 square meters, a floor – area ratio of 2.91, and 1,332 parking spaces. This adjustment involves the internal functions, layouts, and construction areas of multiple buildings. Finally, the construction area of the Phase I has increased by 74.28 square meters, and the 计容 area has increased by 2,863.08 square meters, while the floor – area ratio and the number of parking spaces remain unchanged.
(I) Basic Project Information
Project Name: Operation and Management of Air – Source Thermal Energy for the Phase I Clean Energy Demonstration Project of Nanxi Zhirong Project.
Project Scale: Responsible for the operation and management of air – source thermal energy for Buildings 2457 – 12151617 in the Phase I of the Nanxi Zhirong Project, with a total construction area of 90,257.87 square meters (tentative, subject to the area marked on relevant certificates).
Construction Location: The plot east of the intersection of Renmin Street and South Fourth Ring Road in Nanguan District, Changchun. The four boundaries are clearly defined.
(II) Bidding Content
It includes the operation and management of air – source thermal energy in this area, such as using the air – source heating and cooling system to achieve heating and cooling in the park, and leveraging the smart energy management platform to realize the linkage and optimization of the regional energy system and improve energy utilization efficiency. At the same time, it is responsible for the procurement and installation of the overall facilities and systems in the outdoor air – source heat pump equipment and the cold – heat source station, as well as the operation, maintenance, repair, and replacement of all equipment and facilities. During the management period, except for man – made damage, all operation, maintenance, and repair costs shall be borne by the Party B. After the operation period, the ownership of the equipment and facilities shall belong to the Party A.
(III) Management Period
The construction shall be completed within 70 days after the contract is signed, and the heating conditions shall be met. The operation period is 20 years (from October 1, 2023, to September 30, 2043), starting from the date of the overall project’s successful completion and acceptance. If the above – mentioned date is inconsistent with the actual date of successful completion and acceptance, the operation period shall be calculated from the actual date of successful completion and acceptance. During the operation period, the ownership of all equipment shall belong to the Party B, and after the operation period, it shall belong to the Party A.
