A sanitary stainless steel fan shaped manhole provides practical tank access where conventional openings require too much space. The sector shaped structure is designed for small diameter mixing tanks, helping maximize the feeding port at the tank end while keeping the surrounding area compact. Its geometry also supports easier entry, inspection, cleaning, and maintenance.
Fan Shaped Geometry Changes Tank Access
A stainless steel manway is defined not only by material but also by opening geometry. On small tanks, limited end space can restrict conventional round or square openings. The fan shaped design uses the available area more efficiently, creating a wider practical access opening without requiring the same footprint.
A stainless manway with this structure suits compact mixing equipment where tank geometry, surrounding equipment, and personnel access must work together.
| Design Consideration | Practical Effect |
|---|---|
| Fan shaped geometry | Uses restricted tank end space efficiently |
| Compact access profile | Fits small vessel layouts |
| Smooth sanitary surface | Supports easier cleaning |
| Welded installation | Creates an integrated tank access point |
Stainless Steel Construction Meets Sanitary Needs
The manhole is available in SS304 or SS316L stainless steel, with surface finishing up to Ra≤0.6. Silicone, EPDM, Viton, and NBR gasket options provide flexibility for different process conditions. These features support sanitary tank equipment where surface cleanliness, material compatibility, and sealing performance matter.
- SS304 and SS316L stainless steel construction
- Ra≤0.6 surface finishing
- Silicone EPDM Viton and NBR gasket options
Stainless steel manway lids form part of the complete access assembly, so the cover, gasket, opening geometry, and tank wall should work together. Proper matching supports routine inspection and cleaning.
A Compact Alternative to Conventional Openings
A steel manway needs to match the physical shape and available space of the vessel. This becomes more important when a small mixing tank has limited room around the end or nearby equipment.
The fan shaped configuration provides another option when a circular or rectangular opening is less practical. Its main value is combining usable access with efficient use of restricted tank space.
Installation Details Matter
Correct welding position, gasket selection, and surrounding clearance should be considered before installation. The opening should remain accessible for inspection and cleaning, while the selected gasket should match the process conditions.
The product follows 3A, SMS, DIN, RJT, and IDF standards, with a listed height of 90 mm and a working temperature range of -10℃ to +120℃ when using EPDM.
A stainless steel manway with fan shaped geometry balances tank access with limited installation space, making the design particularly suitable for small diameter mixing tanks.
