Product Description

Stainless steel atmospheric manhole is a widely used equipment in industry and daily life, mainly for the entry and exit of materials and maintenance of containers. Its material and structural design enable it to play an important role in many situations.

Definition and Basic Concepts
Stainless steel atmospheric manhole is a detachable circular or square opening, usually installed on various storage tanks, reaction vessels, pipelines and other equipment. The main function of a manhole is to provide a safe and convenient passage for personnel to enter the interior of the container for inspection, cleaning, and maintenance. Due to its use of stainless steel material, it has good corrosion resistance and strength, making it suitable for various industrial environments

Structural characteristics
The structure of stainless steel atmospheric manhole usually consists of the following parts:

Hole body: The hole body is the main part of the manhole, usually made of high-quality stainless steel material, with good corrosion resistance and compressive strength.
Lid: The lid can be fixed with bolts or quickly locked to ensure that it will not be accidentally opened during use. The design of the lid also takes into account sealing performance to prevent material leakage.
Sealing ring: The sealing ring of manholes is usually made of rubber or other high-temperature and corrosion-resistant materials to improve sealing performance and ensure the safety of the internal environment.
Handle and Lock: The handle design facilitates the opening and closing of the manhole by personnel, while the lock provides additional safety measures to prevent accidental operation.

application area 
The application fields of stainless steel atmospheric manholes are very wide, mainly including the following aspects:

Food and beverage industry: In the production process of food and beverage, stainless steel atmospheric manholes provide convenient access to ensure the hygiene and safety of the production line.
Chemical industry: Equipment such as reaction vessels and storage tanks in the chemical production process require regular inspection and maintenance. The use of manholes can effectively improve work efficiency and ensure production safety.
Pharmaceutical industry: Pharmaceutical equipment has extremely high requirements for hygiene and safety, and the sealing and corrosion resistance of stainless steel atmospheric manholes make them the best choice for the pharmaceutical industry.
Environmental protection industry: In environmental protection equipment such as wastewater treatment and garbage disposal, stainless steel atmospheric manholes can be easily inspected and maintained to ensure the normal operation of the equipment.
Material and Manufacturing Process
Stainless steel atmospheric manholes are usually made of 304 or 316L stainless steel materials. 304 stainless steel is an austenitic stainless steel containing 18% chromium and 8% nickel, which has good oxidation resistance and corrosion resistance, and can resist corrosion from various chemical media. Its mechanical properties are also relatively good, with good formability and weldability, which can meet the requirements of various complex processes.
