Definitions
- the line pipe used to transport crude oil and natural gas containing hydrogen sulfide is required to have so-called sour resistance such as resistance to hydrogen-induced cracking (HIC resistance) and resistance to sulfide stress corrosion cracking (SSCC resistance), in addition to strength, toughness, weldability, and so on.
- HIC resistance hydrogen-induced cracking
- SSCC resistance resistance to sulfide stress corrosion cracking
- HIC resistance hydrogen-induced cracking
- SSCC resistance resistance to sulfide stress corrosion cracking
- Average cooling rate in a temperature range from 750 °C to 550 °C in terms of a temperature at 0.25 mm below the surface of the steel plate 50 °C/s or lower
- the average cooling rate in a temperature range from 750 °C to 550 °C in terms of a temperature at 0.25 mm below the surface of the steel plate exceeds 50 °C/s
- the dislocation density at 0.25 mm below the surface of the steel plate exceeds 7.0 ⁇ 10 14 (m -2 ).
- performing reheating immediately after the stop of the controlled cooling is intended to mean performing reheating within 120 seconds after the stop of the controlled cooling.
