Fiber optic welding machine L-WELD is designed to weld metal plates and pipes. Fiber laser creates a high-frequency beam, which is focused in one spot. This concentrated laser source provides thin, deep welding and is of high speed. Fiber optic:1 T-weld, Butt, Overlapping weld:2 welding stainless steel, aluminum, copper, gold, silver, chromium, nickel, titanium and other metals:3 System of welding consumables automatic supply:4 Safe operation of the equipment:5 easy operation:6 No deformation, increased strength of the weld:7 long life of the equipment:8 weld does not need additional treatment:9 Smooth weld:10 High efficiency:11 Uniform weld area without holes:12

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
