How to better choose Japanese standard flanges and apply them in suitable electric furnace models

How to better choose Japanese standard flanges? The specific basis for selecting Japanese standard flanges is as follows:
Determine the Japanese standard flange specifications based on the connection object, and correctly select the application of the flange according to the requirements of the use of the tubular furnace.
Determine the connection method and sealing surface form between flanges and pipes based on the usage location and connection conditions.
The basic properties of the conveying medium include toxic medium, flammable and explosive medium, general medium, and special medium;
According to the parameters of the medium, when the medium is determined, the nominal pressure PN value of the flange is determined based on the working pressure, working temperature, and working pressure of the medium.
There are currently four types of flange standards in China:
Petrochemical Industry Flange Standard SH3406-1996
Mechanical Industry Flange Standard JB/T74~86.2-1994
Chemical Industry Flange Standard HG20592-20635-1997
National flange standard GB/T9112~9124-2000
The nominal pressures of European system flanges currently include: PN0.25, PN0.6, PN1.0, PN1.6, PN2.5, PN4.0, PN6.3, PN10.0, and PN16.0MPa;
The nominal pressures of flanges in the American system currently include PN2.0, PN5.0, PN11.0, PN15.0, PN26.0, and PN42.0MPa;
Taking the national standard as an example, this article explains the selection of Japanese standard flanges, which are divided into two major systems: the American system and the European system.
