Flare fittings are one of the most common fittings in industrial applications. They are typically used as connections between pipe elements to prevent flow separation. Many types of this type of fitting are available, including wire, hose, or spool. The flare can also be a straight line or curved to meet specifications. Most of them are self-cleaning, to help maintain a constant connection between the elements.
Flush fittings consist of a threaded brass member that is used as an end fitting. It is pushed into a pre-determined spot on the pipe, whereupon it is pulled out and the inner brass sleeve is inserted into the threaded portion of the flare. This allows the end to be pushed against the flanged end to keep it closed. Other types of flange are available with one end threaded, or with a double or multiple flange, so that they may be driven or clamped for tightness.
Flare fittings are usually a temporary fix for gas connections and are used in construction and manufacturing. There are different types of flare fittings, including: cold formed, hydraulic couplings, gas connections, tapered, slotted, flanged, ball and bent termination, internally threaded and externally threaded. They are usually made of corrosion resistant stainless steel, although other metallic materials such as iron or aluminum may be used.
Most common applications of flare fittings use either one or two flange lengths; however, there are sometimes three-foot and four-foot options available. Three-foot and four-foot flare fittings have been designed to handle moderate pressure applications, which are common in most industries. The two-foot option is intended for high pressure applications.
Some of the most common gases, including propane, butane, gasoline, diesel, ethane, methanol, and ethylene-based hydrocarbons (Methylene chloride) are handled by this type of fitting. This means that a flare fitting can be adapted for almost any application. It is important to note that the flexible gas must always be enclosed in a flare fitting. There are many different varieties of flare fittings.
Other flare fittings that are used in the construction and manufacturing industry include: flare connections, flare stoppers, wire nut and flare conduit. All of these fixtures are often referred to as twist fasteners or wrench fittings.
