Abstract
In the article the assessment is made of distribution of temperature tensions in the polymer coatings at pipes atmospheric storing under the low temperatures conditions. For estimation of residual stresses in the protective polyethylene coating of pipes a simplified mathematical algorithm was developed and realized in the program complex MathCad. The estimated value of longitudinal tensions in the coatings at minus 50 0С may be equal to 10,76 MPa, radial tensions to 15 kPa, hoop tensions to 9,8 MPa, tangential tensions to 3,58 MPa.
