As a manufacturer of authentic Songjiang brand shock absorption products, Songjiang Electromechanical Group produces Songjiang brand rubber soft joints that have the functions of shock absorption, noise reduction, and compensation, which can effectively protect pipeline systems. Songjiang Electromechanical Group has also proposed corresponding solutions for various media application scenarios and developed corresponding specialized products, such as SD1ZSJ and SC2ZSJ models specifically designed for acid-base media environments. Below are suggestions on how to correctly select rubber soft joints in acidic and alkaline media environments for reference.
When selecting rubber soft joints in acidic and alkaline media environments, the following factors need to be considered:
  1. Acid and alkali resistance: Select rubber materials with good acid and alkali resistance, such as ethylene propylene diene monomer (EPDM), chloroprene rubber (NBR), polytetrafluoroethylene (PTEF), polypropylene rubber (PP), etc. These materials can maintain good corrosion resistance in acidic and alkaline media, and will not be damaged due to the acidity and alkalinity of the medium.
  2. Temperature resistance: Select rubber materials with suitable temperature resistance based on the specific working temperature, such as silicone rubber (VMQ), fluororubber (FPM), styrene butadiene rubber (SBR), butyl rubber (NBR), polyimide rubber (Aflas), etc. Different rubber materials have different temperature resistance ranges, and appropriate temperature resistance performance needs to be selected based on actual working conditions.
  3. Elasticity and sealing performance: Rubber soft joints need to have a certain degree of elasticity and sealing performance, which can maintain good sealing performance when connecting pipelines and prevent medium leakage. Choose rubber materials with good elasticity and sealing performance, such as nitrile rubber (NBR).
  4. Size and connection method: Select appropriate rubber flexible joints based on the actual pipeline size and connection method. The size of the soft joint needs to match the diameter of the pipeline, and the connection method needs to be adapted to the pipeline connection method, such as flange connection, threaded connection, etc.
  5. Manufacturer’s reputation and quality assurance: Select reputable and quality guaranteed rubber soft joint suppliers to ensure reliable product quality and meet practical work requirements.
  In summary, when selecting rubber soft joints, it is necessary to comprehensively consider factors such as acid and alkali resistance, temperature resistance, elasticity and sealing performance, size and connection method, as well as supplier reputation, and choose suitable rubber materials and product specifications. The SD1ZSJ and SC2ZSJ series of acid-base media specialized products produced by Songjiang Electromechanical Group are well-known in the industry, providing protection for pipelines in acid-base media environments.
