Sanitary Flange
Definition
Basic concept of sanitary flange
The sanitary flange is a fundamental component in plumbing systems, designed to connect and secure the joint between the toilet and the drain pipe. Its main function is to guarantee a hermetic seal that prevents water and gas leaks, maintaining the hygiene and functionality of the sanitary system.
This element is usually manufactured in materials resistant to corrosion and humidity, such as PVC, rubber or polypropylene, and is available in different sizes and designs that adapt to the specific regulations and needs of each healthcare facility.
Characteristics and Types of Sanitary Flanges
Common materials in manufacturing
Sanitary flanges are mainly manufactured from plastic materials such as PVC and polypropylene, due to their chemical and humidity resistance, ease of installation and low cost. These materials guarantee durability and prevent corrosion that could affect the metal flanges.
There are also rubber or elastomer flanges that provide flexibility and better sealing, especially in connections that require absorbing movements or vibrations. Some metal flanges, although less common, can be found in specific industrial or commercial installations.
Types according to design and functionality
Sanitary flanges are mainly classified into rigid and flexible. Rigid ones are ideal for fixed installations with little movement, and are usually made of PVC or polypropylene. The flexible ones, for their part, allow a certain degree of movement, facilitating adaptation in spaces where the alignment is not perfect.
Another classification is based on size, with the most common being 3 and 4 inches, which correspond to the standard diameter of toilet and household sewer pipe connections. There are also flanges with different configurations, such as those with integrated screws for greater fixation or with a built-in seal for quick and safe assembly.
