Large Size clad plates for power generation and chemical industry
Large size Clad plates with the surface square between 20 and 40 m2 are manufactured in accordance with the valid Russian and International standards with the consideration of a number of additional requirements to the base and clad layers depending upon their dimensions and weights.
The base layer of carbon and low alloyed steel Clad plates of Russian and foreign origin is normally made seamless according to the technical requirements of the Customer and additional demands related to the precision of dimensions and flatness.
The clad layer of stainless steel as well as nickel and titanium alloys of Russian or foreign origin, may also be produced by extending with argon arc welding, with the mandatory radiographic control of the welding seem.
In 2013 we have made a pilot sample of a large size plate for the “Nuclear Reactor Emergency Cooling and Protection” (NRECP) (09Г2С-15 + AISI 321 with the dimensions of 90 (84+6) х 2600 х 10600 and the weight around 20 MT (billet dimensions considering the test routine is 2750x10800 mm.
The mechanical properties in the pilot version are much greater than those in the applicable standards (tear strength 476,59 Mpa, shear strength 410,38 Mpa), integrity class “0”.
Currently, in co-operation with the Research Center Prometey, our company is developing the new technical standards applicable to general conditions of nuclear power plants. On June 24, 2015 we have issued the protocol covering our discussion on the application of explowelded steel in the field of nuclear power generation. We have also developed the Technical Assignment related to the inspection procedure of explowelded Clad and in-depth technical standards covering plate Clad.
Above all, in co-operation with the Research Center Prometey, we have developed our Technical Assignment and Commercial Offer related to the manufacture of “Steel Titanium” tube plates with the dimensions of 45(40+5) х 4164 х 4950 for OAO “Silovye Mashiny”
Large size plates for petrochemical and chemical industry are manufactured according to Standard TY 1880-001-15190236-2011, ASTM A263, ASTM A264, ASTM A265 with the consideration of special requirements and weight.
Large size plates with the clad layer of Titanium are manufactured in accordance with Standard TY 5.961-11772-2011 “Clad Plates Steel-Titanium” (by the Research Center Prometey) and a number of additional requirements related to the welded clad layer.
