本文叙述丁和美国腐蚀工程师学去T-IF-9小组委员会的方法相类似的一种评定石油工业中适用于硫化氢气氛的材料的拉伸应力的快速测试方法。硬度范围在HBN137至200中的焊接碳钢试样在低于原设计屈服强度的43％时发生起包和失效,主要起包,发生在未焊接区。与油田环境相似的氢吸收条件下的管材试样的破坏与管理厚度、应力、时间及充氢方法的相互关系有关。低合金钢(AISI 4130及其它;N80管材;NiCrMo低合金在HBN228至269,应力为屈服强度的95％时进行了试验。AISI 4130,Carpenter 450和ASTM A-351级GA6-NM在应力为屈服强度24至67％时发生应力破裂。可是,在使用中,AISI 410在硬度低于HRC 22时表现良好。含有低于1％的Ni的合金钢的使用极限为屈服强度的85％。Inconel X-750,Uranus 50,MP 35N,Nimonic 105在屈服强度的100％时仍未损坏。
This article describes a rapid test method for assessing the tensile stress of materials suitable for hydrogen sulfide atmospheres in the petroleum industry similar to the method used by corrosion engineers in the United States to go to the T-IF-9 Subcommittee. Welded carbon steel specimens in the hardness range HBN 137 up to 200% fail to pack and fail below 43% of the original design yield strength, mainly in uncoated areas. Similar to the oil field hydrogen absorption conditions under the conditions of the pipe sample damage and management of thickness, stress, time and the relationship between hydrogen charging methods. Low alloy steels (AISI 4130 and others; N80 tubing; NiCrMo low alloy were tested at HBN228 to 269 at 95% of the yield strength.) AISI 4130, Carpenter 450, and ASTM A-351 grade GA6- However, in use, AISI 410 performs well when the hardness is lower than HRC 22. The use limit for alloy steels containing less than 1% Ni is 85% of the yield strength. Inconel X -750, Uranus 50, MP 35N, Nimonic 105 are still intact at 100% of yield strength.
