1. After understanding the relevant specifications of the manhole, the nominal diameter, standard, and allowable approval can choose the manhole that suits the corresponding requirements;

2. Confirm the applicable medium, working pressure and temperature of the manhole, or select the corresponding manhole style and material according to the specific working conditions of the medium;

3. Determine the structure style: such as round manhole, oval manhole, square manhole, etc.

4. Determine the material of the main body of the manhole: 304 stainless steel, 316L stainless steel, etc.;

5. Determine whether the manhole needs special attention: such as temperature resistance, anti-corrosion and height requirements of the cylinder section, etc.
