相對浮頂油罐,一般類型油罐的人孔與罐壁結合的筒體是穿過罐壁的,這種人孔不利于浮盤升降和密封。
帶芯人孔是在一般的人孔蓋內加設一層與罐壁弧度相等的芯板,并與罐壁齊平。為便于啟閉,在孔口結合筒體上還裝有轉臂和吊耳,操作時人孔蓋仍不離開油罐。內浮頂油罐人孔,一般至少設2個:一個距罐底板約700mm處,用于清洗油罐及檢修人員進入;一個距油罐底板約2400mm處,為操作人員登上浮盤用。
GTG帶芯人孔選型標準: 中石化標準 GRK型DN500 PN0.25 (96KG) GRK型DN600 PN0.25 (126KG) 
標準L-1/22 DN600 PN0.25 (156KG) 
機械部標準 JB580-79回轉蓋人孔
帶芯人孔裝于油罐下部,人可以由此進出。本產品出廠時不帶加強板。
