A high temperature solar heat collecting tube and its producing technology mainly applies to tank type solar high temperature heat electric power generation field. The heat collecting tube includes external glass tube and coaxial metal internal tube, corrugated pipe with expansion compensation function is joined with the metal tube by connecting parts, the other end of the corrugated pipe is welded with metal-glass transition parts kovar ring, then the kovar ring is sealed-in with the glass tube, in order to protect glass and glass sealing-in part against radiation, a sunshade hood is mounted at the outer side of sealing-in part, a thin-wall lightproof ring is welded on the corrugated tube. The said glass tube is made of DM308; DM305 or DM320 molybdenum group glass, the kovar ring is made of 4j29 or 4j30 iron-nickel-cobalt low expansion alloy.
