Hygienic stainless steel manhole installation requirements description

Hygienic stainless steel manholes should be located near the right side of the inlet and outlet pipes, and try to make the manholes close to the tank chambers for personnel access, maintenance of oil tanks and ventilation nozzles.
Since the manhole is installed on the lowermost body ring of the oil tank, leakage prevention is particularly important. It is required that the joint surface of the two flanges must ensure the straightness and no whirling phenomenon. Reinforced plates and flanges should be cut as much as possible on the entire steel plate without splicing. Sealing rings are machined on the flanges and cover plates, so pay special attention to protection during construction. Sealed with 3mm thick asbestos rubber gasket, no cracking is allowed. When tightening the bolts on the manhole cover, it is necessary to apply diagonal force to prevent deformation of the hole cover.
The products are used in large tanks and containers in the fields of dairy products, beer, food, beverage, pharmaceutical, bioengineering, etc.
 
Sanitary stainless steel manhole is a negative pressure manhole
Made of SUS304, 316L, it can meet the special requirements of various media in food and bio-pharmaceutical fields. It can be applied to stainless steel cans and containers in dairy, beer, food, beverage, pharmaceutical, bioengineering and other industrial fields. Occasionally, access to the interior of the large tank and container can be locked.
