Product Description: this series of sealing gasket includes manhole gasket for pressurizer (bmcmhr), primary manhole (bmcmhp), secondary manhole (bmcmhs), hand hole (bmchh) and observation hole sealing gasket for steam generator Bmceh, which adopts the sealing structure design of metal to metal, has excellent thermal shock resistance and alternating load resistance. The gasket has high stability, safety and reliability throughout its service life. Meet all kinds of harsh working conditions.
• The new metal to metal structure can achieve higher sealing stress with less compression and meet the operating conditions of the pressurizer and steam generator
• Enhanced gasket compensation stress relaxation ability, adapt to frequent temperature and pressure fluctuations
• The reliability of gasket has been fully verified by rigorous 100 times thermal cycle test
