不銹鋼材質304/316L方形人孔

人孔是指用于人員進出設備以便安裝、檢修和安全檢查的開孔結構。主要由短筒節（或短管）、法蘭和帶把手的人孔蓋組成。從安全檢查考慮，壓力容器要求開設的人孔數及其最小尺寸見“檢查孔”。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蓋和吊蓋；人孔開后速度有普通式和快開式，人孔結構和尺寸一般都已標準化，可參照有關手冊選用或設計。

人孔已有成型產品，直徑通常為600mm。人孔中心距地板一般為750mm。便于工作人員在安裝、清洗、維護時進出油罐或通風。

非金屬油罐的人孔設在罐頂上，金屬油罐的人孔設在罐壁最下圈板上。大都為直徑600mm的圓孔，其中心距底板750mm，為油罐清洗或維修人員進出油罐用，又稱作道門。檢修清理油罐時刻利用人孔進行采光和通風。立式油罐的容量在5000m3以下時設1~2個人孔，5000m3以上的設2個人孔。人孔的安裝應與進出油管線相隔不大于90°。當只設一個人孔時，應將其置于罐頂透光孔的對面；當設2個人孔時，其中一個設在透光孔的對面，另一個應至少與第一個人孔相隔90°。

Stainless steel 304/316L square manhole

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. For safety inspection, the number of manholes required for pressure vessels and their minimum size are shown in "Inspection Holes". 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.

Manholes have formed products, usually 600mm in diameter. The center of the manhole is generally 750mm from the floor. It is convenient for staff to enter and exit the oil tank or ventilate during installation, cleaning and maintenance. square manhole

The manhole of the non-metal oil tank is set on the top of the tank, and the manhole of the metal oil tank is set on the lowermost ring plate of the tank wall. Most of them are round holes with a diameter of 600mm, the center of which is 750mm from the bottom plate, which is used for tank cleaning or maintenance personnel to enter and exit the tank, also known as the door. Always use manholes for lighting and ventilation during maintenance and cleaning of oil tanks. When the capacity of the vertical oil tank is less than 5000m3, there are 1~2 manholes, and if the capacity is more than 5000m3, there are 2 manholes. The installation of the manhole should be no more than 90° away from the oil inlet and outlet pipelines. When there is only one manhole, it should be placed opposite the light-transmitting hole on the tank top; when two manholes are set, one of them should be located opposite the light-transmitting hole, and the other should be at least 90 degrees apart from the first manhole. °.
