本文介绍了寒冷地区用高强度薄壁地面输油管用钢。
The present paper described the high strength thin wall tube steel used for oil transferring in the exfremety cold region.
较低退火温度获得高强度、高屈强比易表现出循环软化特征,不利于提高连续油管的疲劳寿命。
At lower annealing temperature obtain high strength and high yield ratio showed cyclic softening feature easily. That is detrimental to the using life of coiled tubing.
