Double-Ferrule Compression Fittings: Benefits and Applications
Double-Ferrule compression fittings are the most common types of instrumentation pipe fittings with versatile applications. These pipe fittings find applications in industries like defence, aerospace, oil and gas, chemical processing plants, process measurement and control, and even medical equipment.
What are double-ferrule compression fittings?
Double-ferrule compression fittings have three parts, the nut, the body for tube fittings, and the ferrules (on one or two sides). The sequential grip that such a design gives this tube makes it very effective. Most instrumentation fittings come with United National Extra Fine (UNEF) threads. The fitting sizes rely on the tube's outer diameter. The ferrule fit into the tubing by compressing, ensuring strong connection.
A double-ferrule instrumentation fitting features a male and a female end. This male end has a counter-bore (recessed) and matches the tube's outer diameter. In addition, it also has an inner cone.
Pros and cons of double-ferrule compression fittings
These pipe fittings are available in various sizes and material grades per requirement. These fittings also possess some advantages and disadvantages like other pipe fittings as follows:
Pros:
· Availability: The good part about double-ferrule tube fittings is that they are available in all sizes, materials, shapes, and combinations.
· Strong and secure: After following all the right steps during installation, these fittings can make leak-free and strong connections.
· Resistance: Double-ferrule pipe fittings are more resistant to vibrations, giving them an advantage over other instrumentation pipe fittings, like cone and thread pipe fittings.
· Reliability: Double-ferrule pipe fittings are safe, and one can utilize them in all systems- low or high-pressure ratings.
· Performance: Double-ferrule pipe fittings well with thin and thick wall tubings.
· Flexible: Double-ferrule pipe fittings have high flexibility, ensuring versatile application in different piping systems.
Cons:
· Complex designs: Double-ferrule tube fittings have complex designs leading to incorrect installation. As a result, it requires one to be more careful.
· Requires a Proper Selection of Tubes: Selecting the wrong tube can lead to an unreliable performance on the part of the tubing system. It is a common error, and one must pay close attention to it.
· Lubrication requirement: Galling is a common problem for these fittings due to their threads. It is essential to lubricate double-ferrule tube fittings due to the threads on the mating nuts.
· Longer Process of Installation: One needs to be very careful while installing double-ferrule tube fittings, as these tubes have to undergo cutting, deburring, chamfering, and other processes, ensuring no defects or scratches.
· Corrosion: Corrosion is another possibility among double-ferrule tube fittings due to their materials and applications.
· Expensive: Finally, double-ferrule pipe fittings are costlier than non-instrumentation pipe fittings.
