Regarding the selection of 800HT flanges
Thread Content
There is a device with a temperature of 930 degrees Celsius and a pressure of 1.2 MPa. It is intended to use ASME B16.5 standard flanges for the pipe flanges, but ASME B16.5 does not provide a pressure rating table corresponding to flanges made of the material N08811. Additionally, N08810 can only be used at a maximum temperature of 816 degrees Celsius. Is it still possible to use standard flanges in this case?
Flanges that fall outside the standard parameter range cannot use this standard. Non-standard flanges can be designed, but at such high temperatures, flange connections are not reliable; welding is recommended.
Designed for industrial furnaces; has been used in other devices as well
