Mechanical properties of tubes in a solid state control in the annealed samples. Samples taken from tubes that are made in the solid state, have, after annealing in air for one hour at 650º C - 700º C. 

The tubes should be sealed. Control discontinuities is performed using the eddy current flaw detector. 

Other requirements according to GOST 17217-79, TU U 14-00195452.026-99.
