Lid

Stainless steel tank lids are tried and tested closure components in the manufacture of silo, process, sterile and pressure vessels. They are primarily used in the food and beverage industry, but also in the pharmaceutical industry.

 

Due to their design, the tank lids are characterized by a fast opening and closing system compared to conventional flange connections. Robust hinges replace the familiar clamping elements and always center the lid when closing.

The unpressurized tank lids are supplemented by pressure dome lids, which in turn are divided into different pressure levels. The pressure levels depend on the operating pressure, temperature and other loads (e.g. an agitator).

Wetted parts are made from the material 1.4404 (316L). In addition to the standard surfaces, we can offer you a wide range of qualities for internal and external surfaces.

This type of lid is mainly used in storage tanks and provides access for maintenance and repair. Due to the conical shape of the frame, the tank lid can be easily adapted to the tank.

The installation position is on the side in the lower area. This enables safe and easy access to the tank. The stable water column supports the seal. The lid is also CIP-compatible.

The P11 manhole cover is also available in several variants with a flat frame and a deep frame. All of them allow very good cleaning and access to the tanks in the same installation position.

 

 

The pressure dome cover is used in pressure vessels. It allows the tank interior to be inspected. The design can be used to accommodate agitators, sight glasses and cleaning equipment.

The installation position is usually on the tank. However, the pressure dome cover can also be installed on the side.

The pressure load depends on the diameter, the number of tommy screws and the temperature. The dome cover is sealed by the preload force of the tommy nut.

 

 

This component was developed for unpressurized containers. The outer door serves as an inspection hatch on machines.

It is installed in the spray area above or below the water level. The design is easy to operate and enables optimum opening and closing without tools.

 

 

The cover type P31 was designed for unpressurized tanks. It is mainly mounted on the tank as a dome lid. It must be ensured that the liquid level is below the tank lid.

The design makes it easy to open and close without the need for tools. The fixed connection between the bracket and the cover ensures that the cover can be easily placed on the frame, thus ensuring a secure seal. It provides access for maintenance and repairs.

It can also be used to fill a container. The lid can also be used to accommodate inlet nozzles, sight glasses or other connections. This lid is both a very inexpensive and high-quality variant for use in an unpressurized tank.

AWH also offers other lid variants for even more areas of application. The portfolio includes pressure dome lids as well as pressureless and sterile versions.
