- What is a Stainless Oval Manhole Cover?
A stainless oval manhole cover is an access cover made of stainless steel with a durable structure, generally used in water, chemical, and food storage tanks. Thanks to its oval shape, it can be easily integrated into tank or pipe systems and provides a tight seal.
- Types of Stainless Oval Manhole Covers
Stainless oval manhole covers are produced with different features according to the area of use and need:
- Pressure Covers: Designs resistant to high pressure.
- Non-Pressure Covers: Used in low-pressure environments.
- Manhole Covers with Sight Glass: Designs with a glass section to observe the contents.
- Quick Open/Close Covers: Covers equipped with special hinge systems for practical use.
- What Materials Are Used?
304 and 316 stainless steel are generally used for stainless oval manhole covers. These types of steel offer high resistance to corrosion, ensuring long-term use. 316 grade stainless steel is particularly preferred in areas that come into contact with seawater, chemical substances, and food.
- Production Process and Quality Standards
The production of stainless oval manhole covers is carried out in accordance with specific quality standards. During the production process:
- Laser cutting and precision bending processes are applied.
- Durability is increased through welding processes.
- Quality control is ensured by passing sealing tests.
- Hygienic surface coatings suitable for the food and chemical industries are applied.
Covers with quality certificates such as ISO 9001 and CE offer high durability and safety.
- Areas of Use and Sectoral Applications
Stainless oval manhole covers are widely used in the following sectors:
- Food industry (milk, beer, beverage production)
- Chemical and pharmaceutical industry
- Water treatment and wastewater management
- Petrochemical plants
- Pressurized and non-pressurized tank applications
- Use in the Food Industry
Hygiene is one of the most important elements in food production. Stainless oval manhole covers meet food safety standards thanks to their bacteria-resistant surfaces and easy-to-clean structures. They are particularly preferred in milk, beer, and beverage production.
- Use in the Chemical and Pharmaceutical Industry
Manhole covers used in the chemical and pharmaceutical industries are produced from materials with high chemical resistance and are resistant to aggressive substances. This ensures a safe working environment.
- Use in Water and Wastewater Treatment Plants
In wastewater treatment plants, stainless oval manhole covers offer long-term use thanks to their durable structures. Their sealing properties prevent water leaks and contribute to the efficient operation of the system.
