Our Production
The workshops of the “Zarya” Chemical Equipment Plant in Dzerzhinsk are furnished with all the necessary welding, boiler, metal-working, pressing, furnace, painting equipment, accessories and tools.
There is a number of special equipment units which helps to eliminate manual labour when flanging housings and jackets, roll forging shells and pipes, joining annular seams of process vessels.
Over the past few years, we have significantly updated the welding equipment fleet, purchased equipment for assembling annular seams of process vessels, equipment for bending profiles and pipes, CNC machines for roll forging sheets and pipes, CNC metal-cutting equipment.
As our production facilities are mobile, modern and technologically equipped, we can feel confident about the future.
