METHOD OF MANUFACTURING PIPES FROM CARBON STEEL |
| 摘要 |
FIELD: manufacture of high-strength oil application pipes resistant to sulfide corrosion cracking. SUBSTANCE: method includes pipe rolling at 850-930 C, cooling from temperature of rolling end in water for 1-2 s down to temperature of 630-670 C, repeated heating up to 780-830 C with subsequent cooling in water and tempering at 650-720 C. EFFECT: higher strength properties of pipes and their resistance to sulfide corrosion cracking. 2 cl, 1 tbl
