Stainless steel pressure manhole is an important component used for pressure vessels or non pressure vessels, usually made of 304 or 316L stainless steel material. It is designed as a quick opening structure, connected by upper and lower flanges, and has a sight glass installed on the manhole cover for easy observation of the internal situation of the container. Stainless steel pressure manholes are widely used in industries with high medium requirements such as food and biopharmaceuticals, such as large tanks and containers in dairy products, beer, pharmaceuticals, and other industrial sectors.
Material and specifications
The main materials for stainless steel pressure manholes include 304 and 316L stainless steel. Its specifications range from a nominal diameter of DN150mm to 600mm and can be customized according to specific needs.

Application scenarios
Stainless steel pressure manholes are suitable for various equipment that requires frequent inspection and maintenance, especially in industries such as food and biopharmaceuticals that have strict hygiene requirements. Its quick opening structure makes operation convenient, safe, and has a beautiful and durable appearance.

Installation and maintenance
When installing stainless steel pressure manholes, it is important to apply even force to prevent deformation of the cover plate or damage to the glass caused by uneven force. Regular inspection and maintenance can ensure its long-term stable operation.
