    Packing & Loading

    In piping, a Gasket is sealing material placed between connecting flanges to create a static seal, which will maintain the leakage proof sealing in all operating conditions. Different types of gaskets are used to achieve the leak proof sealing between the pipe flange. The primary function of gaskets is to seal the irregularities of each face of the flange so that there will be no leakage of the service fluid from the flange joint.


    Types of Gaskets to be used in given fluid service is depends on the parameters such as

    1. Temperature – Gasket material must withstand entire design temperature range of the fluid it handles.

    2. Pressure – Gasket material must withstand entire design pressure range of the fluid it handles.

    3. Corrosion resistance – Gasket material should not corrode when it comes in contact with the fluid it handles or by the environmental exposure.

    4. Types of fluid – Gasket material should be capable of dealing with different type of fluids if installed in line that handles more than one types of fluids.

    5. Robustness – The gasket must be capable of withstanding all movement that may occur due to change in temperature and pressure.

    6. Availability – Gasket should be easily

    7. Cost – Cheap and unreliable gasket should not be used at the same time it should not be costly.


    Selection of Gasket

    Proper selection of gasket depends upon following factors.

    Compatibility of the gasket material with the fluid.

    Ability to withstand the pressure-temperature of the system.


    The service life of the gasket

    It is important to understand the requirements of particular applications before making gasket selection. Gaskets must maintain a seal for an acceptable period against all the operational forces involved. There are eight important properties which any gasket must possess to achieve this –

    1. Impermeability – The gasket should not be porous to the fluid being sealed.

    2. Compressibility – The gasket should compress into the imperfections on the flange sealing faces to create the initial seal.

    3. Stress relaxation (creep resistance) – The gasket should not show significant flow (creep) when subjected to load and temperature. Such flow will allow the bolts to relax, reduce gasket surface stress and cause leakage.

    4. Resilience – Although normally stable, flanges do in fact move slightly relative to one another under the influence of cycling temperature and pressure. The gasket should be capable of compensating for such movements.

    5. Chemical resistance – The gasket should withstand chemical attack from the process medium being handled. Likewise, the gasket material itself must not contaminate the process medium.

    6. Temperature resistance – The gasket should be able to withstand the effects of the maximum and minimum temperatures within the process and the external atmospheric temperatures.

    7. Anti-stick – The gasket has to be easily removable after use.

    8. Anti-corrosion – The gasket must not cause corrosion of the flange faces.


    Types of Gaskets

    There are three types of gaskets used in process piping.
