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.
OVEN THERMAL TREATMENT AND SECONDARY THERMAL TREATMENT
The plant uses both oven and secondary thermal treatment.
Oven thermal treatment and heating of bottom blanks are performed in an oven with a size of 3.36 х 5.5 m, designed for bottom blanks with a diameter up to 2,800 mm.
The new technology providing for volumetric secondary heat treatment of vessels is implemented by heating from the inside using a diesel fuel heat generator. From the outside, the vessel is insulated with mineral wool broached mats, then thermoelectric converters are installed and connected to the Yokogawa mR2000 temperature monitoring and recording device.
The entire process, from the beginning of heating to complete cooling of the product, is monitored and reflected in the diagram. Depending on the vessel volume and weight, heat treatment can be carried out with either one or two heat generators.
