POSSIBILITIES OF INCREASING CONNECTIONS DURABILITY FOR LARGE DIAMETER PIPES, BY GLASS COATING INTERNAL SURFACE

Cristel MUREŞAN, Gheorghe ACHIMAŞ

Abstract


Time of operation, or durability, of a part represent the actual time of operation until reaching the limit condition of wear. Bends are the parts of the fluids transport installations subject to wear, erosion being the main cause of degradation. When flow direction is changed using bends, the particle would not follow the fluid, but would impact the bend wall. Interior coating of bends used enamelling technology by applying frit produced by Pemco BVBA company in Bruges. A mixture of three frits has been used, as follows: 5% (R5750); 25% (R10) and 70% (R25). Glass coating the interior surface of bends has the advantage of substantially reducing the friction between the fluid and the interior surface of the bends, increasing the operational durability of bends.
