人孔是指用于人員進出設(shè)備以便安裝、檢修和安全檢查的開孔結(jié)構(gòu)。主要由短筒節(jié)（或短管）、法蘭和帶把手的人孔蓋組成。從安全檢查考慮，壓力容器要求開設(shè)的人孔數(shù)及其。人孔材料有碳鋼和不銹鋼。按受壓情況人孔分為常壓和受壓人孔；按形狀人孔分為圓形、橢圓形和矩形人孔，矩形人孔僅適用于常壓設(shè)備；按安裝位置人孔分為水平和垂直安裝人孔；人孔蓋固定方式有迥轉(zhuǎn)蓋和吊蓋；人孔開后速度有普通式和快開式，人孔結(jié)構(gòu)和尺寸一般都已標準化，可參照有關(guān)手冊選用或設(shè)計。

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.
