Rectangular manway
A374 (420x310)
Rectangular manway A374
Rectangular A374 vertical manway with a cover that opens to the inside of the tank. The manway cover is supported by two internal hinges, so it opens safely and smoothly. This model will be great for smaller tanks and wherever compact size will be an advantage.
This model has been designed for installation in the side wall of stainless steel tanks. The pressure of the tank contents on the manway increases overall tightness of the closure.
As standard, the A374 manway is manufactured from AISI 304 grade stainless steel, and optionally from AISI 316L. A wide range of elastomers used in the production of gaskets, allows the manway to be used for a wide range of working mediums (fluids, liquids).
The use of stainless steel rectangular manway A374
The main areas of application are:
- food industry,
- beverage and alcohol production,
- chemical and biotechnology industries,
- industrial equipment and chambers.
With good results, the manway is successfully installed wherever the parameters of the materials used for its construction allow its application.
