Stainless Manhole Cover
What is a Stainless Manhole Cover?
Stainless manhole covers are lids, usually designed in a round or oval shape, that provide access to the inside of closed systems such as tanks, boilers, and reactors. They both allow human access and ensure the safety of the system.
Why is Stainless Steel Preferred?
Stainless steel is the most preferred material for manhole covers due to its durability, hygienic structure, and long service life. Stainless steel is especially indispensable in sensitive sectors such as food, chemical, and pharmaceuticals.
Structure of a Stainless Manhole Cover
Materials Used
Generally, AISI 304 or AISI 316 grade stainless steel is used in stainless manhole covers. Grade 316 is preferred in environments requiring high corrosion resistance, while grade 304 is suitable for more standard conditions.
Production Processes
Each manhole cover, which undergoes laser cutting, welding, polishing, and sealing tests, is produced with high precision. Silicone, EPDM, or Viton gaskets are generally used for sealing.
Standard Sizes and Custom Production Options
Manhole covers can be produced in diameters ranging from 200 mm to 600 mm. However, production in custom sizes and connection types is also possible.
Areas of Use
Use in the Food Sector
Thanks to its hygienic structure, it is used in milk, olive oil, beverage, and other liquid food production facilities. With its cleanability and bacteria-resistant structure, it complies with HACCP standards.
Use in the Chemical and Pharmaceutical Industries
The sealing and resistance properties of manhole covers are of great importance in tanks where chemicals are transported and stored. It does not deteriorate in acidic or basic environments.
Role in Water Treatment and Storage Systems
Stainless manhole covers are indispensable for inspection and maintenance in water tanks. Thanks to their corrosion-resistant structure, they can be used safely for years.
Advantages of Stainless Manhole Covers
Durability and Long Life
Thanks to its stainless steel structure, it can be used for years without deformation. It shows high resistance against impacts and external factors.
Hygienic Structure
Thanks to its non-porous and smooth surface, it does not harbor bacteria. It can be easily sterilized.
