卫生级常压人孔简介和用途：

是安装于各种不锈钢罐顶端，作为工作人员安装、维修、清洗、维护时的进出通道和通风口！一般不锈钢人孔使用304和316两种材质的钢板作为原料来制作，也可以根据客户的要求制作。人孔应有一个设在进出油管右侧附近，并尽量使人孔正对罐室密闭门，以便人员进出、维修油罐和通风接管用。由于人孔安装在油罐的下层体圈上，防渗漏就显得特别重要。
要求两法兰结合面必须保证其平直度，无飘扭现象。加强板和法兰应尽量在整块钢板上切割而不拼接。法兰和盖板上加工有密封圈，在施工中要特别注意保护。密封用3mm厚石棉橡胶垫片，不允许有折裂。安装人孔盖板上紧螺栓时，要成对角均与用力，以防孔盖变形。

Sanitary manhole is installed in a variety of stainless steel tank top, as a staff installation, maintenance, cleaning, maintenance of access and ventilation! General stainless steel manhole using 304 and 316 two materials of steel plate as raw materials to produce, can also be made according to customer requirements. A manhole should be located near the right side of the access pipe and should be positioned as close as possible to the airtight door of the tank room for personnel access, maintenance of the tank and ventilation connections. Because the manhole is installed on the lower body ring of the oil tank, the anti-leakage appears to be 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, must form a pair of angle all with the force, in order to prevent the manhole cover deformation. Product name: stainless steel manhole, round manhole, quick opening manhole, normal pressure manhole, type: round (normal pressure and 3 kg pressure type) material: 3043016L 321304L 316. Standard: according to the national manhole related standard requirements production, size: according to user requirements to map, sample size processing, specifications: 150MM-300MM finish: surface polishing or Matt. Product packaging: Carton, shock-proof film, external processing: according to user requirements to map, sample processing non-standard products, product prices: negotiation, online quotation, negotiable
