The steam turbine cylinder sealant MFZ-4 is a high-temperature sealant, which can play an excellent sealing role in the high-temperature and high-pressure steam of steam turbine. It has following functions:

1. Connect the split joint of steam turbine cylinder to achieve the purpose of sealing and bonding.

2. Prevent steam leakage and penetration. The cylinder sealant MFZ-4 has good filling and wettability, can fill tiny gaps and form a barrier impervious to liquid and gas, which is used to prevent leakage and external environmental impact.

3. It can be used alone or combined with sealing rings, copper sheet, asbestos gasket, etc. to apply to the high-temperature sealing of the flange surface of other high-temperature hot furnace pipes.

Main Features of Cylinder Sealant MFZ-4:

1. Good thermal stability, can withstand high temperature without degradation or combustion. The MFZ-4 sealant uses materials and additives with good thermal stability, and can work at 600 ° C or higher.

2. Resistance to high-temperature chemical medium erosion. MFZ-4 sealant has good protection against high temperature and possible chemical media, and will not age or fail rapidly due to chemical attack.

3. Keep good performance at high temperature. At high temperature, the MFZ-4 sealant will not significantly soften or harden, and can maintain good mechanical strength, elasticity, and leakproofness.

4. Strong oil and water resistance. MFZ-4 sealant can prevent liquid and gas penetration under high temperature, and has strong oil and water resistance.

MFZ-4 sealant is not only used in steam turbines, but also widely used in chemical, steel, paper mills, sugar mills and other industries, such as:

·Sealing and lubrication of cylinder head joint surface of steam turbine and gas turbine.
·Sealing and lubrication of cylinder end faces of compressors, steam engines and turbines.
·Sealing and lubrication of parts in contact with acid, alkali and steam under high temperature and pressure.
·Sealing of high temperature furnace pipe flange and oil and gas field deep well drilling tools.

High-Temperature Sealant Recommendation

If you want to use high-temperature sealant on other equipment except steam turbine, how to choose? Here YOYIK recommends the following selection criteria for you:

1. Working Temperature: select according to the ambient temperature of the sealant, especially in high temperature environment. It is necessary to select the high-temperature resistant sealant with appropriate ambient temperature.

2. Working Pressure: select according to the pressure of the sealant. Sealants used for high-pressure structures must be able to withstand high pressure. For example, MFZ-4 sealant can withstand the pressure of up to 32MPA.

3. Working Medium: select according to the medium contacted by the sealant, such as fuel, coolant, etc., in order to prevent the medium from corroding the sealant.

5. Gap size: select according to the size of the gaps to be sealed. Different gap sizes require different viscosity of sealant. MFZ-4 sealant can be used in 0.5-0.7mm gap and has excellent sealing performance.

6. Performance: select the appropriate sealant according to other performance requirements of the sealant, such as viscosity, hardness, tensile strength, elasticity, etc.
