Introduction: A glass-lined quick-opening manhole or hand-hole is a type of access port that is used in glass-lined vessels. It provides a convenient and safe way to access the interior of the vessel for maintenance, cleaning, or inspection purposes.
The quick-opening manhole or hand-hole consists of a metal frame with a glass-lined cover that can be easily opened and closed. The glass lining provides excellent corrosion resistance and prevents contact between the process fluid and the metal frame, ensuring long-lasting performance and reducing maintenance costs.
The quick-opening manhole or hand-hole is typically installed on the top or side of the glass-lined vessel and is secured with bolts or clamps. It can be opened and closed quickly and easily, allowing for rapid access to the interior of the vessel.
Advantages:
