| Abstract: | It has been investigated in the paper for the problem about the brittle cracking of the prestress tube when the thermal recovery of heavy oil with the steam injection is made Based on the analysis of the material composition, guantity of hydrogen, fracture morphology, microstructure, stress statement and surrounding of prestress tube It is considered the crack of prestress tube is due to delayed cracking by hydrogen |
| |
| Keywords: | prestress tube low temperature delayed cracking |
