Metal wrapped gasket for shell and tube heat exchangerThere are generally several types of gaskets, such as box gaskets, floating head gaskets, box side gaskets, outer head cover gaskets, and head cover gaskets. Depending on the different pipe passes, there are different gasket forms. For multi pipe passes, different forms of ribs are generally required on the inner ring, which are usually wrapped with ribs or solid core ribs with graphite on both sides;The production process of welding the reinforcing bars on the inner side of the inner ring of the winding gasket is quite complicated. For some inner ring sealing surfaces smaller than 6mm, stainless steel bars with a diameter of 3.2mm are generally used as the inner ring, and the basic body production is the same as that of the standard winding gasket.
Performance characteristics of metal wrapped gaskets:
1. The winding surface of the gasket is tightly combined with the flange surface Ensure good sealing effect,
Under conditions of alternating temperature and pressure The use effect is outstanding,
3. The inner ring of the wrapped gasket provides a guarantee for the compressive performance of the gasket,
4. The structure and form of the reinforcement can be changed according to different requirements Ensure better sealing effect under different working conditions
Shell and tube heat exchanger tube box gasket, floating head gasket, tube box side gasket, outer head cover gasket, and head cover gasket, etc

Metal wrapped gaskets are an ideal choice for flange seals in valves, pumps, pressure vessels, and other applications due to their high mechanical strength, ease of use, good compression resilience, and suitability for use in harsh temperature fluctuations. Another prominent feature of metal wrap mats is the large selection space, as the product has a wide range of material selection and diverse structures, which can meet the different needs of different users.

Metal wrapped gaskets are suitable for various corrosive chemical fluids, strong alkalis, hydrochloric acid, sulfuric acid and other highly corrosive liquids, organic solvents, liquid nitrogen, etc. They are widely used as static sealing components at flange connections of pipelines, valves, pumps, heat exchangers, towers, manholes, handholes and other industrial equipment such as petroleum, chemical, synthetic fiber, coal mining, power generation, metallurgy, etc. The metal graphite wrapped gasket has good compression resilience and is suitable for sealing parts with severe temperature and pressure fluctuations. It has excellent characteristics such as good impermeability, long service life, and maintenance free.

1. The metal wrapped gasket has excellent high temperature resistance because it can be used normally between -200~850 ℃

2. The sealing performance of the metal wrapped gasket is not affected under a pressure of 0-20MPa, so its pressure resistance is also tested by JD's postgraduate entrance examination

3. With a variety of styles and materials, there is ample space for customers to choose from

4. Stable and reliable sealing performance, long service life,
