Stainless Steel Food Grade Custom Bolted Square Manhole
Square Manhole is made of 304 or 316 material, the sealing material is silicone, EPDM, Nitrile, Viton, and the handle can be made of plastic or stainless steel according to the need.
Working Principles
The working principle of a stainless steel square manhole is essentially that of a rigid, enclosed structure that provides a safe, sealed access for maintenance of tanks, containers, or equipment. It is permanently welded to the flange of the equipment opening, and its core function is to provide a reliable opening and closing passage for maintenance or inspection.
Stainless Steel Manhole Specification Chart
Radius | 200mm-1000mm |
Pressure | 0-5bar |
Material | 304/316L |
Seal Material | Silicone, EPDM, Nitrile, Fluorine rubber |
Outer surface treatment | Mirror polishing, matte |
Inner surface treatment | 0.8μm-0.4μm |
Features
● The main body is made of 304 or 3016L stainless steel, offering excellent corrosion resistance and a smooth, easy-to-clean surface.
● The square design makes more efficient use of space (compared to a round shape), and the structure is robust.
● Equipped with silicone or EPDM gaskets, and secured with evenly tightened bolts for reliable sealing.
● Compatibility and compliance: Customizable to meet specific requirements.
Application
Stainless steel square manholes are critical components in industries where hygiene, corrosion resistance, and structural integrity are paramount. They are extensively used in the food and beverage industry for tanks and processors requiring frequent cleaning, and in the pharmaceutical and biotechnology sectors to maintain sterile environments in vessels and bioreactors. The chemical and petrochemical industry relies on them for their durability in handling aggressive substances, while water and wastewater treatment plants utilize them for access points in treatment tanks due to their resistance to corrosion.
