Wenzhou HongTai Fluid Equipment Co.Ltd\" \/>\n<meta property=\"og:description\" content=\"Stainless steel manholes include pressure manholes and non-pressurized manholes, of which the non-pressurized tank manholes can provide SS304 or SS316. They are mainly used in tank equipment such as atmospheric storage tanks and mixing tanks to check the liquid level, while maintaining control of the air at the top of the tank - the manhole is sealed and prevents air exchange. The manhole is usually installed on the top of the tank, and its size depends on the condition applied: larger ones facilitate the addition of solids, or smaller ones for the addition of liquids or powders. Manhole pressure depends on the thickness of the wall of the stainless steel material and the thickness of the flange ring, we can provide round manholes, square manholes and oval manholes. According to different customer needs, we can customize the glass manhole, with breathing valve manhole, the surface can be sandblasted or mirror polishing  Glass manholes are very convenient for observing tank materials. We can also install manholes with lights, which are slightly more expensive than other manholes, which are suitable for the installation of atmospheric tank tops. The functions are divided into fully enclosed, observable glass mirror type and observable glass mirror type with light.

They are mainly used in tank equipment such as atmospheric storage tanks and mixing tanks to check the liquid level, while maintaining control of the air at the top of the tank - the manhole is sealed and prevents air exchange. The manhole is usually installed on the top of the tank, and its size depends on the condition applied: larger ones facilitate the addition of solids, or smaller ones for the addition of liquids or powders. Manhole pressure depends on the thickness of the wall of the stainless steel material and the thickness of the flange ring, we can provide round manholes, square manholes and oval manholes. According to different customer needs, we can customize the glass manhole, with breathing valve manhole, the surface can be sandblasted or mirror polishing  Glass manholes are very convenient for observing tank materials. We can also install manholes with lights, which are slightly more expensive than other manholes, which are suitable for the installation of atmospheric tank tops.
