Zusammenfassung:	The present invention relates to a method for producing tubing products from binary and multicomponent zircon alloys, consisting in obtaining from an ingot previously submitted to a beta distortion process a source preparation, hot forming said source preparation at the subsistance temperature of zirconium alpha + beta to get a tubular blank, hardening the latter at a temperature higher by 30 to 60~ to the temperature at which the alloy passes from an intermediary state (zirkonium alpha + beta to the beta state of zirconium, mechanically processing, followed by a tempering process at the subsistance temperature of alpha zirconium, cold distorting the tubular blank with intermediary annealings at the temperature of alpha zirconium until the finished product is obtained, the cold distortion of the tubular product being effected with the following global stretching: .mu..SIGMA.100 for the finished products and .mu..SIGMA.50 for the TREX or SUPER TREX-type semi-finished tubular products, whereby at the first stage of the cold distortion the stretching .mu..SIGMA.2,0, .mu.=Sprod./Stub. (where Sprod. is the crosssectional surface of the product before the milling process and Stub. is the cross-sectional surface of the laminated tube) and .mu..SIGMA.=Ssource material/Sfinished tube (where Ssource material is the cross-sectional surface of the blank before the first milling process and Sfinished tube is the crosssectional surface of the finished tube after the last milling process.
