High temperature and pressure safety valve leak? A variety of standards for high temperature steam valve sealing requirements are generally no obvious smoke is considered to meet the requirements. There is generally no problem with the emergence of a small safety valve on the on-line safety valve. It is advisable to install an exhaust pipe to direct the steam to a safe area for export. Safety valve test is generally carried out at room temperature, the media is compressed air. Mainly look at the safety valve setting performance and sealing performance. Effectiveness of the working conditions when not so bad online, sealing performance easier to meet. How much pressure relief valve is high pressure? Low-pressure safety valve: Nominal pressure PN ≤ 1.6Mpa safety valve Medium-pressure safety valve: Nominal pressure PN2.5 ~ 6.4Mpa safety valve High-pressure safety valve: Nominal pressure PN10.0 ~ 80.0Mpa safety valve High pressure safety valve: nominal Pressure PN> 100Mpa safety valve high temperature and pressure safety valve manufacturers Recommended: Shanghai and Shanghai Engineering Valve Factory (Group) Co., Ltd.
