The calculations and experiments have show that the value of axial pressure must be at a level of 0,05 t of the tube metal, the factor accounting for the axial pressure in calculating the test pressure being taken close to K=0,95. With the observating of the recomended schedule, the tube testing in the elastic deformation region is ensured which complies with the accepted specifications Product Description popup.authors popup.nrat_date 2020-04-03 Close
