Stainless Steel Hygienic Pressure Inspection 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. The outer surface is mirror polished or matte polished.
Working Principles
The stainless steel square manhole provides a sealed access point for tanks and pressure vessels. It uses a gasket to form a tight, hygienic seal between the cover and the frame. When closed and locked, it maintains pressure, prevents leakage, and keeps contaminants out. Operators can quickly open the cover for inspection, cleaning, or maintenance, then re-seal and lock it to restore safe operating conditions.
