Our Watertight Doors for Industrial Tanks and Containers
Portex designs and manufactures in France a complete range of watertight doors for industrial tanks and containers. Thanks to our in-house design office, we offer custom solutions tailored to the most demanding environments.
A Complete Range of Watertight Doors
Round Doors
Depending on the shape of cylindrical tanks, these standardized doors offer a perfect balance between compactness, ease of installation, and excellent pressure resistance. They are suitable for most industrial applications.
Rectangular Doors
Their geometry allows easy access for cleaning, inspection, or maintenance operations. They are particularly suited for large-capacity tanks requiring a front opening.
Oval Doors
Thanks to their compact profile, oval doors fit into tight technical areas while ensuring reliable and watertight closure. Their design optimizes the space-to-opening ratio.

Embedded Doors
Designed to be sealed onto the tank, these doors ensure structural integration without flanges or added components. They offer a durable and hermetic solution for demanding environments.

Autoclave Doors
Designed to withstand high thermal and pressure cycles, these doors resist sterilization processes (SIP/CIP) and ensure production line safety.

High-Pressure Autoclave Doors
Equipped with reinforced locking systems, these doors are specifically designed for high-pressure environments. They ensure maximum sealing under extreme conditions.
Bolted Manholes
Easy to install and maintain, these technical access points allow quick intervention inside the tank. The bolted system ensures solid closure and excellent mechanical strength.
