The generalized model of long durability construction's elements on the basis of integral-average equivalent stresses is offered. It is shown, that integral-average equivalent stresses are practically invariant sizes during deformation of a pipe from elastic (elastoplastic) conditions down to fracture. Results developed a generalized model for thick-walled pipes are resulted at creep for one-parametrical loading with use of various kinds integral-average equivalent stress are given. Check of adequacy calculation's data to experimental data is executed.
