Production of hexahedral pipe blanks from centrifugally cast 04[ETH][yen]14[ETH][cent][ETH]-[ETH] 1[ETH][curren] ([ETH]![ETH]82) steel billet for the nuclear industry

A new production technology for centrifugally cast 04[ETH][yen]14[ETH][cent][ETH]-[ETH] 1[ETH][curren] boron-steel has been developed. In addition, technology has been developed for the production of hot-rolled 290 12 mm pipe from such blanks on a TPU 8-16 double prime system with Pilger mills and for the conversion of such pipe to hexahedral pipe blanks (dimensions 257 +2/-3 6 +2/-1 4300 +80/-30 mm). The hexahedral pipe blanks produced by this means meet the requirements on the geometric dimensions, mechanical properties, and intercrystallite corrosion in Technical Specifications TU 14-3-1630-89 for the manufacture of racks used in holding tanks at nuclear power plants and in spent-fuel transportation.
