JSC "Uralkhimmash" made the shipment of the second reactor for hydrotreating of "Saratov Oil Refinery" (Rosneft). 170 tons weight reactor diameter 3.8 meter, height 17.6 meter wall thickness of 100 mm. The reactor is designed to remove sulfur diesel fraction.
The equipment operates in a corrosive environment at high working temperature — 400 ° C and a pressure of — 5.7 MPa, and therefore the reactor used for the manufacture of chrome stainless steel, and the inner surface of the body was clad stainless steel.
In the manufacture of the body of the metal used advanced technologies utilized in OAO "Uralkhimmash" — explosive welding and electroslag-layer deposition method. For the manufacture of shells body has been mastered and applied electro-welding strip electrode width of 60 mm. Metal for the bottom of the reactor was made by explosion welding. There are plans to improve the performance of work at surfacing through the use of an electrode strip width up to 90 mm.
The plant "Uralkhimmash" with the support of a strategic financial partner OAO "Gazprombank" held during the past year a large-scale modernization aimed at introducing new modern methods of welding and welding for the manufacture of heavy equipment from heat-resistant chromium-molybdenum steel with corrosion-resistant plating. Within a few months of production have been launched for the installation of electroslag welding tape systems for internal welding pipes, installation of automatic welding in narrow-gap butchering, set for automatic welding of pipes and fittings in the enclosure. Was upgraded welding positioner for welding bottoms capacity of 150 tons. To ensure welding processes were acquired four settings for pre-and concomitant heating.
The development and introduction of new equipment allowed JSC "Uralkhimmash" to enter the market of large-size reactor equipment operating at high temperatures and pressures in harsh environments. In particular, the new welding equipment shown to be effective in the manufacture of reactors for hydrotreating of "Saratov Oil Refinery".
Transportation of the reactor to the installation site of the customer made a special rail transporter, accompanied by two backup trucks, cars and crews cover DPS.
Recall of "Uralkhimmash" won the tender for the manufacture and supply of reactor equipment for the hydrotreating of "Saratov Oil Refinery" in 2010.
