The stainless steel sanitary circular pressure manhole is an inspection and operation window designed for closed tanks and piping systems. It not only provides internal visibility, but also can withstand certain pressure fluctuations. The stainless steel sanitary circular pressure manhole is usually used in tanks or containers that require sealing and pressure bearing capacity, such as fermentation tanks, storage tanks, reactors, etc. At the top or side of these pipes or containers, the pressure manhole not only facilitates personnel to enter for inspection and cleaning, but also ensures that the quality of internal materials or production safety will not be affected under high temperature and high pressure conditions. Common types of stainless steel sanitary circular pressure manholes include: standard pressure manhole, pressure manhole with sight glass, quick-opening pressure manhole, pressure manhole with exhaust function, double-locking pressure manhole, high temperature and high pressure pressure manhole, and pressure manhole with pneumatic switch device.

Stainless Steel Sanitary Round Pressure Manhole For Dairy Products
The stainless steel sanitary circular pressure manhole not only provides an entrance for inspection and maintenance, but also undertakes the task of maintaining system stability, optimizing production processes and improving safety. Its design takes into account the micro-positive or micro-negative pressure environment inside the tank, which can effectively prevent tank deformation or sealing failure caused by pressure fluctuations. In addition, it can also reduce the risk of leakage of high-pressure water flow or steam during cleaning, ensuring the stability of the internal environment of the tank during CIP/SIP cleaning. In some special scenarios, it can also serve as a safe buffer point, playing a certain buffering role when the pressure surges unexpectedly, avoiding damage to the tank or overflow of internal materials due to instantaneous pressure changes. For systems that need to store active substances for a long time, its high sealing can prevent oxygen infiltration or loss of volatile components, ensuring stable product quality.
Working Principles
The working principle of the stainless steel sanitary circular pressure manhole mainly depends on its powerful sealing and pressure-bearing design. First, in the tank or pipeline system, the pressure manhole forms a sealed contact with the pipeline or container through a flange or welding connection. When working, the sealing ring of the pressure manhole (such as silicone, PTFE, etc.) maintains a good seal under high pressure environment to prevent liquid, gas leakage or contaminants from entering. To ensure the stability of the internal pressure, the pressure manhole is usually designed with a pressure release device, which can automatically exhaust when the pressure is too high, maintain the balance of internal and external pressures, and avoid system damage caused by pressure fluctuations. When maintenance, cleaning or sampling is required, the user can open the manhole through a quick-open device or manual operation, and operate after the internal pressure is released.
