  • Method for producing an alloy for a reforming tube
    Patent number: 10501831
    Abstract: The invention relates to a microstructure of an alloy for a tube for reformers, having an austenitic matrix structure, characterised in that: i) primary micrometric precipitates in the form of M23C6-type carbides, where M=Fe, Ni or Cr, and/or M(C,N)-type carbides, where M==Nb or Ti, are formed during the solidification of the alloy; ii) secondary nanometric precipitates in the form of M23C6-type carbides, where M=Fe, Ni or Cr and/or M(C,N)-type carbides, where M==Nb or Ti, are formed during the activation of the tube; and iii) between 0.1 and 0.3% of Ni16Si7Nb6-type intermetallic precipitates is formed during the use of the tube.

  • Method for replacing tubes in a reforming unit
    Patent number: 8776340
    Abstract: The invention relates to a method for replacing tubes in a hydrocarbon-vapor reforming unit, that comprises before launching any new production campaign: measuring the expansion of the tube diameters; taking X-ray photographs of the tubes; realizing replicas of the surfaces of the tubes; wherein a tube is replaced when it fulfills at least one of the following conditions; the diameter expansion is higher than 3%; the X-ray photograph includes at least one crack; the replica shows a sufficient thermal ageing and/or creep deformation.
