Stainless steel rectangular manways are typically used as the main inspection element, installed in the side shell of a tank or silo. This makes rectangular manways suitable for a wide variety of areas. In the area of the food industry, these will include:
- fruit and vegetable processing,
- milk and dairy processing plants,
- warehouses and processing plants for bulk materials (e.g. cereal grains),
- alcohol production (in particular – wine).
However, the use of rectangular manways is not limited to the food industry, but goes much further. Rectangular manways in the proper configuration are also ideal for other industrial applications. Thus, they are used:
- in various process vessels in the chemical and biotechnological industry,
- in process water tanks,
- in industrial washers,
- in chambers and dryers,
- in silos for plastic granulates,
- in civil engineering and hydraulic structures.
Extra large rectangular manways are the answer to the specific needs of technical, service and maintenance personnel. Often the activity of these services involves working in the confined environment of tanks, chambers, pipelines and similar spaces. Manways are installed in all such areas to provide safe access to the interior. The dimensions of such manways are based on the requirements in EN 547-1 (Part 1: Principles for determining the dimensions of openings for whole-body access to machinery). As a result, such manways have an opening that an adult of average body build can easily pass through. They are usually not smaller than 600×450 mm.
