Few Important Information About Sanitary Fitting
All sanitary fittings are so designed and constructed that it will be used in food, beverage, pharmaceutical, medical and biological applications. In such applications, cleanliness and sterility is very important.
Therefore, all fittings and sanitary replacements parts are usually constructed of such materials that can ensure sterile environment to maintain sterility during their use.
The fittings are categorized depending upon 3 different kinds of vessels which are designed for:
Pipes are made of hollow cylinders by using uniform material having some amount of permanence and rigidity. Pipe sizes will be defined nominally, which may vary based on ANSI, ASME and API standards.
Pipes and tubes are often can be interchanged in industry and the basic difference will be how the dimensions are specified. Usually, tubes are defined with their exact dimensions.
Hoses are typically more portable and flexible and are usually made up with multiple layers of various materials that may vary depending upon the use.
Types of Fittings
All sanitary fittings are classified on the basis of connection type and the function it will perform.
Following are the different connection types:
- Ball and sleeve type fittings
Outer sleeve is connected to inner fitting.
- Barbed fittings
Used mainly for low pressure uses, since no strong seal is provided.
- Cam-lock fittings
They are mainly used in heavy-duty applications.
- Compression fittings
They connect vessels by using compression on ring, gasket or ferrule.
- End fittings
For making connections it will provide specific type of end surfaces
- Crimp fittings
These fittings need crimping tools for making the connections.
While connecting pipes and tubes, these fittings will be attached separately to vessel ends. Typically, flange connections are built in the hose.
- Luer locks
Most commonly thy are used for connecting tubes in various medical as well as laboratory applications.
- Push-on fittings
Fittings that have ends designed for accepting vessels by pushing all them into the one end. Typically, these fittings disconnect through some collar retraction type.
In the system where during the operation frequent disconnections and again reconnections are needed, in such place quick connections will be more convenient for those sections.
- Threaded fittings
These fittings are with screw threads which is built-in grooves in their inner which is female or outer which is male surfaces are designed for accepting tubing having matching threads.
For proper selection of fittings, the engineers will decide based on the function and their applications.
