Title: Method of cryogenic vessel flaw detection
Inventor: GUSEV A L
IPC: G01M3/28
Filed: 1996-02-27
Granted: 1998-04-20
Abstract: FIELD: flaw detection of large thick-walled cryogenic reservoirs. SUBSTANCE: after cryogenic liquid is drained from cryogenic vessel and the latter is heated, cryogenic vessel is heated every time up to some constant temperature. Then it is controlled thermostatically and at the same time heat-insulating space is evacuated to some pressure $$$. In this case, pressure is checked by means of nitrogen trap positioned in front of manometric sensor. After pressure is stabilized pumping-out is stopped, and heat-insulating space is coupled with space which contains temperature-controlled nondispersed chemical absorber of nitrogen. Pressure reduction process in heat-insulating space to valve $$$ and process of pressure stabilization to value $$$ are observed and recorded. Then rate of pressure increase is determined, space containing the chemical absorber is separated from heat-insulating space, further process of pressure rise to value $$$ is observed, and pressure increment rate is determined. This done, dependence of summary hydrogen gas evolution from time of operation and number of cycles of thermocycling vessel is obtained. This dependence is used to determine porosity of surface turned to heat-insulating space. When porosity value becomes equal to maximum permissible one at number of cycles of $$$, the remaining permissible number of cycles is determined by formula $$$, where $$$ is safety margin factor according to number of cycles. EFFECT: higher accuracy of flaw detection process. 5 dwg

Granted: 1998-03-27
Abstract: FIELD: plastic metal working, specifically processes of anchoring of tubes in tube grates by directed localized deformation of tube material. SUBSTANCE: process includes formation of ring protrusions on outer surface of ends of tube, installation of tube in hole of grate having ring recesses of rectangular cross-section. Registration of tube against possible axial displacement and its further anchoring in grate with provision for match of protrusions and recesses is carried out by application of radial effort from side of inner surface of tube. Outer thickening is formed on tube end, for instance, by sequential upsetting with simultaneous calibration of hole of tube over length of thickening prior to installation of tube into hole of grate. Ring protrusions are formed on thickened part of tube creating first ring protrusions with trapezoidal cross-section and geometric dimensions exceeding required ones. After this geometric dimensions of ring protrusions are brought to required ones by surface deformation of material of tube, for example, by forming with the aid of gauges.

Title: Method of exclusion of metal corrosion (metal dusting) in direct reduction of material containing iron oxides (versions)
Inventor: GERAL D KERN
IPC: F27D17/00
Filed: 1995-06-20
Granted: 1999-05-10
Abstract: FIELD: metal corrosion control. SUBSTANCE: synthesis gas is mixed with blast-furnace gas produced in direct reduction of materials containing iron oxides and used as reducing gas for reduction of materials containing iron oxides. To exclude or reduce metal corrosion (metal dusting) caused by high content of CO in reducing gas, use is made of simple methods and equipment to maintain CO/CO 2  ratio in reducing gas within the preset range of 1:3. In the first version, synthesis gas is used in the form of natural gas and CO/CO 2  ratio in reducing gas is regulated by means of regulation of operation of reformer in which steam reforming of natural gas is effected by varying the steam/natural gas ratio. The second version provides for regulation of CO/CO 2  ratio by addition of one part of volume of converted gas produced in reformer from steam and natural gas and then supplied to CO-converter to increase content of H 2 , to blast-furnace gas directly, that is by bypassing CO-conversion in the amount which may be varied. The third version includes cleaning of converter gas and optionally blast-furnace gas from CO 2  before their use as reducing gas, and addition directly to reducing gas of at least a part of converted gas without cleaning from CO 2 . In the fourth version, converted gas and optionally blast-furnace gas may be subjected to cleaning from CO 2  and CO/CO 2  ratio is regulated by addition directly to reducing gas of at least a part of volume of blast-furnace gas without cleaning from CO 2 . In the fifth version, converted gas and optionally blast-furnace gas are subjected to cleaning from CO 2  before its use as reducing gas. In this case, content of CO 2  in cleaned gas is regulated by varying the efficiency of CO 2  separation. For the further reduction of metal corrosion (metal dusting), it is good practice to supply to reducing gas at least a part of sulfur present in material containing iron oxides in the form of H 2 S formed in heating or in direct reduction corresponding together with blast-furnace gas. In so doing, it is useful to maintain the content of H 2 S in reducing gas with the help of blast furnace gas equalling from 20•10 -6  to 40•10 -6 , preferably 25•10 -6 . EFFECT: higher efficiency. 16 cl, 1 dwg, 9 tbl
