不銹鋼材質(zhì)304/316L不銹鋼人孔

人孔已有成型產(chǎn)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(fēng)。

非金屬油罐的人孔設(shè)在罐頂上，金屬油罐的人孔設(shè)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(fēng)。立式油罐的容量在5000m3以下時設(shè)1~2個人孔，5000m3以上的設(shè)2個人孔。人孔的安裝應(yīng)與進出油管線相隔不大于90°。當(dāng)只設(shè)一個人孔時，應(yīng)將其置于罐頂透光孔的對面；當(dāng)設(shè)2個人孔時，其中一個設(shè)在透光孔的對面，另一個應(yīng)至少與第一個人孔相隔90°。不銹鋼人孔

人孔應(yīng)有一個設(shè)在進出油管右側(cè)附近，并盡量使人孔正對罐室密閉門，以便人員進出、維修油罐和通風(fēng)接管用。

由于人孔安裝在油罐的最下層體圈上，防滲漏就顯得特別重要。要求兩法蘭結(jié)合面必須保證其平直度，無飄扭現(xiàn)象。加強板和法蘭應(yīng)盡量在整塊鋼板上切割而不拼接。法蘭和蓋板上加工有密封圈，在施工中要特別注意保護。密封用3mm厚石棉橡膠墊片，不允許有折裂。安裝人孔蓋板上緊螺栓時，要成對角均勻用力，以防孔蓋變形。

Stainless steel 304/316L stainless steel manhole manhole has been formed products, the diameter is usually 600mm. Manhole Center from the floor is generally 750 mm. Facilitate the staff in the installation, cleaning, maintenance of access to oil tanks or ventilation. The manhole of the non-metal oil tank is arranged on the top of the tank, and the manhole of the metal oil tank is arranged on the lowest ring plate of the tank wall. Most of them are round holes with a diameter of 600mm, the center of which is 750mm away from the bottom plate. Maintenance and cleaning of oil tanks always use manhole for lighting and ventilation. When the capacity of vertical oil tank is below 5000m3, there are 1 ~ 2 manholes, and above 5000m3, there are 2 manholes. The manhole shall be installed not more than 90 ° apart from the inlet and outlet pipelines. When only one manhole is provided, it shall be placed opposite the light hole on the tank top; when two manholes are provided, one of them shall be located opposite the light hole and the other shall be at least 90 ° apart from the first manhole. The stainless steel manhole shall be provided with a manhole located near the right side of the inlet and outlet tubing, and shall be as close as possible to the airtight door of the tank chamber for Personnel Access, maintenance of the tank and ventilation connections. As the manhole installed in the tank on the lowest layer of the body ring, anti-leakage is particularly important. It is required that the joint surface of the two flanges should be straight and free from torsion. Stiffeners and flanges shall be cut as far as possible on the entire steel plate without splicing. The flange and the cover plate processing has the sealing ring, must pay special attention to the protection in the construction. 3 mm thick asbestos rubber gasket for sealing, no cracking is allowed. When installing the bolt on the manhole cover plate, apply equal force in diagonal to prevent the manhole cover from deformation.
