round manhole with pressure

Manhole refers to the opening structure used for personnel to enter and exit equipment for installation, maintenance and safety inspection. It is mainly composed of short tube section (or short tube), flange and manhole cover with handle. From the point of view of safety inspection, the number of manholes and "inspection holes" required to be opened in pressure vessels.

round manhole with pressure

Sanitary manholes are used in food, pharmaceutical, winemaking, and chemical industries.

The material is stainless steel 304 316L 904L Q235B TA2

Pressure range can be customized

Manhole refers to the opening structure used for personnel to enter and exit equipment for installation, maintenance and safety inspection. It is mainly composed of short tube section (or short tube), flange and manhole cover with handle. From the point of view of safety inspection, the number of manholes required to be opened in the pressure vessel and its size. Manhole materials are carbon steel and stainless steel. Manholes are divided into normal pressure and pressure manholes according to the pressure condition; manholes are divided into circular, oval and rectangular manholes according to shape, and rectangular manholes are only suitable for atmospheric pressure equipment; manholes are divided into horizontal manholes according to the installation position and vertical installation of manholes; the fixing methods of manhole covers include swivel cover and hanging cover; the speed of manhole opening is ordinary and quick-opening, and the structure and size of manholes are generally standardized.
