During the construction of an industrial facility, much attention is paid to the strength of the service pipelines fasteners. It is also necessary to provide reliable connection of all units of industrial equipment with the pipelines. In this case, it is not always possible The use of a permanent welded joint is not always possible, therefore, there are various types of weld-free tight joints. FLANGE JOINT COMPONENTS At present, one of the most effective connections used in industrial facilities is a flange joint. This is an airtight connection that provides high structural integrity, consists of two flanges, fasteners (studs or bolts, washers, nuts) and gaskets. An important matter in choosing a set of flanges is tightness. The gasket material must have good elasticity, strength, resistance to the operating temperature conditions and to the media with which direct contact is expected. For flange joints, Villina company uses the following types

Composite’s Bolts, nuts, bushings, studs from carbon (carbon fiber). Carbon or more precisely CFRP (Carbon fiber reinforced polymer) has very light weight and in the same time they are strong like a steel bolt. Unlike steel, these bolts have high strength and rigidity. Carbon Fiber Bolts perfectly fits of light weight construction and for reaching reduced weight of this construction. They are also having resistance against heat, chemical and corrosion, low weight and high strength at the same time Carbon bolts are very good alternative to Steel Bolts.
