Flare Fittings | Sizes On Average

Flare fitting is essentially a term that we would find in the field of engineering, one that many may not be familiar with, although many people will have used them in many situations, unaware of the technical term. These fittings are found in all households, for example to carry mains gas into your house from the gas pipes we find in our streets. Flare fittings are used when joining together pipework, be it a temporary join for filling a fuel tank, or emptying a sewage tank for example, or for a permanent join of two pipes when adding additional pipework to existing pipework, or adding to existing pipework. Flare fittings come in different sizes, denoted by the angle of the flared edge, the most common two sizes being a 37 degree and 45 degree flare. JIC fittings, which are the most common type of pipe fitting in the hydraulics industry, having gained almost the entire niche of the market due to their durability , economic pricing, and easy assembly, are 37 degree Flares.

The fitting together of two pipes by Flare fittings is known as a forging process, the Flared edge of one pipe fitting inside the sleeve of the second pipe, and then being secured by a Flare nut.
Flare fittings are used in circumstances where reliability is crucial and in situations where the pipes will have a liquid delivered through them at great pressure, or where machinery vibrates, in these circumstances, flexible piping usually is used to prevent distortion. This type of security from leakage is essential in highly populated areas where liquids are transported by great pressure, leakage leading to little less than environmental disaster.

Flare fittings are of essentially a very simple design as they contain only three essential parts, each of which can be replaced separately if necessary, although Flare fittings very rarely need replacing as they contain no perishable substance such as rubber, relying on metal on metal contact.

Flare fittings are made of a wide variety of metals such as steel, stainless steel, copper, and nickel - copper alloys. The fittings can be used with both metric and non metric systems within the hydraulics industry, as JIC fittings can provide converters to convert from one system to another, the exact measurements of both sides of the flare fittings being measured with a gauge that will give both metric and imperial readings. JIC fittings are world renowned in the hydraulics industry, being 37 degree Flare fittings. Other companies are starting to introduce other fittings, but as compatibility between these new systems and the renowned JIC fittings is very limited, JIC maintain the hold on the hydraulics market, having more than thirty years of production experience as well as an unbeatable choice of shapes and sizes.

The obvious advantages of using this type of fittings when joining pipes are the simplicity, yet strength of the structure, being able to withstand enormous pressure, as well as the economic prices and huge variety of Flare fittings that are available on the market. The only disadvantage of Flare fittings, or thing of which you must be aware when using these fittings in your day to day businesses etc. is that the over tightening of the Flare nut, followed by dismantling and re assemble may distort to an extent the pipe, and cause small leakage, the same as would happen if the Flare fitting was not connected tight enough.
