Abstract

The level of corrosion resistance and conditions of corrosion cracking of the bush insert of two-layer oil well tubing fabricated from 5Kh13N2MB martensitic stainless steel are found. The average rate of general corrosion under the conditions of autoclave testing is found, which is used for the evaluation of the service life of tubes. It is found that the fabrication technology of two-layer tubes being used has a negative effect on the corrosion properties of the material of the bush insert.
