What’s flange insulation kit?
A flange insulation kit consists of a flange gasket, bolts and insulating sleeves used to install a leak-proof flange. The insulating sleeves used in the kit are manufactured of a high-density, polyethylene plastic that prevents an electrical charge from dissimilar metals from causing corrosion and ultimately weakening and breaking a flange bolt. In place of a conventional nut and bolt system, the flange insulation kit uses a stud with a washer and nut on each end of the flange joint.(types of flange insulation gasket kit)
When fluid flows through two dissimilar metals, an electrical charge is often produced. Moreover, a chemical reaction is often created that causes the deterioration of the metals at the connection. In a typical pipeline, this weak spot is the flange. The corrosion is commonly responsible for the breaking and failure of flange bolts where the two dissimilar metals are joined. By installing a flange insulation kit, the union of the two metals is often made more trustworthy.
The key components in the kit are the polyethylene insulating sleeve and mounting stud. The insulating sleeve is inserted into the bolt holes of the flange using one insulator on each side of the flange. This results in two insulators per bolt hole being inserted into the flange. The mounting stud is then inserted into the insulating sleeves until threads on each end of the stud are visible outside of the flange. A flat, steel washer is slid onto the stud at each end, and a nut is threaded onto each end of the stud and tightened.
By tightening a nut on each end of the stud, the connection of the flange insulation kit becomes much stronger than the typical nut-and-bolt type connection. When a nut is tightened onto a bolt in the traditional manner, all of the clamping force is applied to the single set of threads on the bolt. When a double-ended stud is used, such as in a flange insulation kit, the clamping force is divided equally between the threads on each end of the stud as well as inside both nuts. The stud, suspended away from the metal flange inside of the plastic-like sleeves, is protected and insulated from any electric charge and corrosion. This creates a flanged connection that will not corrode or fail due to a chemical reaction between two dissimilar metals.
