A Pipe Ferrule is a name for various
types of metal objects, of which most consist of a circular clamp used
to hold together and attach fibers, wires or posts. A pipe ferrule is thus a
ring or cap attached to an object to protect against damage, splitting
or wear. It is also known as a circular fitting device that is used to
hold the pipes together.
A pipe ferrule is used in various industries like hardware, electrical & electronics, fiber optics, lawn and garden instruments, automotive, compressed-gas, fire suppression, welding, furniture, beverage, appliance, farm and lighting industries etc. Ferrule, apart from holding parts of a rod etc together, are also used for giving strength to weakened materials and for preventing wearing or splitting. A few of the applications of Pipe Ferrule :
Also known as a Tube insert, ferrule can also be a metal, glass,
plastic or ceramic tube that is inserted into the end of a heat
exchanger tube to provide a specific function. The purpose of a ferrule
here is to either be sacrificial to the effects of inlet-end erosion,
corrosion, impingement, or induce a fluid to fall on the ID of a tube in
a falling film exchanger, or transfer extremely high heat past the tube
sheet to the exchanger tubes. Each of the above applications requires a
specific style of design.
Even though there are some applications where plastic performs satisfactorily, a metal tube insert is more durable in environments where there are concerns of the stability of the product, its tendency to transfer erosion problems down the tube, its durability in an abrasive environment and its reaction to elevated temperatures. In some cases, ceramics also exhibits good performance well like in a situation when the temperatures are extremely high. Also, ceramic bonds well to glass and its expansion coefficient is close to that of the glass fibers, making it environmentally stable. However, ceramics can be subject to breaking. Some of the metal ferrules are :
