Rectangular manway
A381 (225x175)
Rectangular manway A381
Rectangular vertical manway A381 with cover opening outside the tank. The small size and solid construction make the manway well suited for places where it is necessary to open the cover frequently to inspect the process. If necessary, the manway will also allow sampling, product filling or inserting of a washing ball.
This model was developed for installation in the side wall of stainless steel tanks. It can also be used as an upper manway, both in tanks and in other applications requiring increased corrosion resistance and small dimensions.
As standard, the A381 manway is manufactured from AISI 304 grade stainless steel, and optionally from AISI 316L grade steel. A wide range of elastomers used in the manufacture of gaskets, allows the manway to be used for a wide range of working media (fluids, liquids).
The use of stainless steel rectangular manway A381
The main area of usage is:
- food industry,
- beverage and alcohol production,
- chemical and biotechnology industries,
- small tanks.
With good results, the manway is successfully installed wherever the parameters of the materials used for its construction allow its application.
