Flexible single sphere rubber expansion joint play a crucial role in the outfit of shipyards

Flexible Single Sphere Rubber Expansion Joint plays a significant role in the outfit of shipyards, primarily used for connecting piping systems and addressing stress concentrations caused by issues such as thermal expansion and contraction, vibration, or displacement of pipes, thereby protecting the safe operation of pipes and equipment. Below are some suggestions regarding the selection and use of flexible single sphere Rubber Expansion Joints in shipyard outfits:
  1. Material Selection:

    Rubber Material: In shipyard environments, where seawater and salt spray are highly corrosive, it is necessary to choose rubber materials with good corrosion resistance, such as fluoroelastomer (FKM) and nitrile rubber (NBR). These materials not only resist corrosion from seawater but also exhibit excellent resistance to high temperatures, oils, acids, and alkalis.

    Reinforcing Material: To enhance the strength and wear resistance of Rubber Joints, reinforcing materials such as nylon cord fabric are often added.

  2. Structural Type:

    Flexible single sphere rubber joints feature a simple structure and easy installation, making them suitable for connecting piping systems in shipyards. When selecting, ensure that the joint matches the interface of the piping system to avoid installation issues.

  3. Working Pressure and Temperature:

    Select the appropriate Rubber Joint model based on the working pressure and temperature requirements of the piping system. Generally, rubber joints come in various working pressure ratings such as 0.6MPa, 1.0MPa, 1.6MPa, and 2.5MPa.

    In terms of temperature, consider the temperature of the medium in the pipes and the high or low temperatures in the shipyard environment to choose a rubber joint with suitable temperature resistance.

    When installing rubber joints, ensure they are in a natural state, avoiding artificial deformation or excessive stretching. At the same time, follow the installation instructions to ensure the joint's sealability and stability. For rubber joints that need to be used overhead, elastic supports can be equipped to reduce the burden on the joints.

  4. Maintenance:

    Regularly inspect the condition of rubber joints, including whether the appearance has damage, aging, or leakage. If necessary, replace aged or damaged joints promptly.

    Avoid contact between rubber joints and sharp metal instruments to prevent puncturing the sphere.

  5. Precautions:

    During use, pay attention to whether the pressure and temperature of the piping system are within the bearing range of the rubber joint, avoiding overpressure or overtemperature use.

    In case of abnormal situations (such as increased vibration, noise, etc.), inspect and address them promptly to ensure the safe operation of the piping system.

    The selection and use of flexible single sphere rubber joints in shipyard outfits require comprehensive consideration of factors such as material, structure, working pressure, temperature, as well as suppliers. During use, strictly follow the installation instructions, and regularly perform maintenance and inspections to ensure the normal operation of rubber expansion joints and extend their service life.
