Horizontal canned pumps with welded bodies (Villina-GNGC) are designed for transit in stationary conditions of neutral, corrosive, toxic, as well as explosive and fire hazardous liquids, the vapors of which can form explosive mixtures with air. These pumps are used in petrochemical, petroleum refining and other industries.
single-stage or multi-stage version of the unit design (increased discharge pressure, in contrast to back pull-out pumps);
high efficiency of the impellers;
a possibility to pump contaminated liquids with 100% tightness (for pumping units with combined seals);
Temperature of the pumped fluid: up to +420°С.
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
