PTFE-lined rubber joints are also called soft rubber joints, rubber joints, rubber flexible joints, rubber elastic joints, pipe shock absorbers, etc. It is a pipe joint with high elasticity, high air tightness, medium resistance and weather resistance. This product uses the elasticity, high air-tightness, medium resistance, weather resistance and radiation resistance of rubber, etc. It is made of polyester cord fabric with high strength, strong cold and heat stability, and then obliquely compounded. After high pressure and high temperature, The mold is vulcanized. Fluorine lining is mainly used in strong corrosive conditions. Line fluoroplastics (commonly PTFE, nylon) where metal pressure vessels (valves, tanks, etc.) or rubber products (rubber joints, compensators, etc.) need to be in contact with strong corrosion. Etc.) to prevent the medium from corroding the pressure vessel.
PTFE-lined joints are hollow rubber products used for flexible connection between metal pipes. It consists of inner and outer layers of rubber, ply and traveller, which form a tubular rubber piece. After vulcanization, it is combined with a metal flange or a parallel joint loose sleeve. This product can reduce vibration and noise, and can compensate for thermal expansion and contraction caused by temperature changes. It is widely used in various piping systems. This product is manufactured by Xinli Company using a new process of air-blowing mold. It is a product composed of inner rubber layer, reinforcement layer, middle rubber layer, outer rubber layer composite sphere and loose-forged low-carbon steel flange. It has high pressure resistance. , Good elasticity, large displacement, good vibration and noise reduction effects, easy installation and so on. In addition, the product has good acid and alkali resistance and stable chemical state, which can greatly reduce the impact of corrosive media on the rubber joints. Can be widely used in water supply and drainage, HVAC, fire protection, compressors, paper making, pharmaceuticals, ships, pumps, fans and other pipe systems.
Features of PTFE-lined joints: high internal density, high pressure resistance, and good elastic deformation.
Advantages of PTFE-lined joints: shock absorption, noise reduction, lightweight, non-toxic.
Use of PTFE-lined joints: connection with pumps and valves, especially suitable for pipelines with large vibrations and frequent changes in hot and cold. The rubber joint is a joint made of fabric-reinforced rubber parts and loose metal flanges, which is used for pipe vibration isolation and noise reduction and compensation for displacement. It is a pipe joint with high elasticity, high air tightness, medium resistance and weather resistance. Xinli strictly abides by international standards and quality requirements of raw materials, and eliminates the phenomenon of cutting corners. The environmental protection standard means that the raw materials of the product not only need new materials, but also environmentally-friendly new materials.
The reporter learned from the Tianjin International Institute of Biomedicine that the second-phase project of the institute has started preliminary preparations such as planning and environmental assessment, and strives to start construction within the year.
It is reported that the planned total construction area of the second phase of the Joint Research Institute is 230,000 square meters, including the construction of the National Biomedical International Innovation Park headquarters building and the GMP general plant. Among them, the headquarters building has a construction area of 80,000 square meters to create a headquarters base; three general-purpose biological product factories with a total construction area of 65,000 square meters for pilot development and small-scale production; two general chemical and chemical factory buildings with a total construction area of 3.5 10,000 square meters, to meet the needs of the companies settled in the research and development of the laboratory to scale up the research, and some companies invested in the establishment of the plant early and small-scale production of clinical trial drugs; 3 general medical equipment workshops, a total construction area of 50,000 square meters, providing standard production lines And irradiation sterilization centers and other high-standard industrialized environments.
Xinli lined with PTFE rubber joints: connection with pumps and valves, especially suitable for pipelines with large vibration and frequent changes in cold and heat. The rubber joint is a joint made of fabric-reinforced rubber parts and loose metal flanges, which is used for pipe vibration isolation and noise reduction and compensation for displacement. It is a pipe joint with high elasticity, high air tightness, medium resistance and weather resistance. The installation of PTFE-lined joints on the pipeline can effectively improve the resistance to acid and alkali corrosion of the line.
The relevant person in charge of the Joint Research Institute stated that after the biomedical project has grown to a certain stage, a pilot test and production workshop is needed. The second phase of the Joint Research Institute will provide enterprises with accelerator services to help enterprises eventually achieve industrialization. It is reported that enterprises in need can rent for a long time or purchase the venue at a very favorable price and enjoy the various resources provided by the joint research institute. Through the support of the large platform of the Joint Research Institute and the communication between enterprises, in the future, dozens or even hundreds of small giants of biomedical technology will emerge here, which will further promote the gathering of the biomedical industry in Binhai New Area.
