“…Pode-se observar que em todas as condições, as microestruturas são constituídas por ferrita e perlita. Como o aço A é considerado de média temperabilidade, este resultado era esperado para ciclos de austenitização seguidos de resfriamento ao ar calmo (normalização) [31]. No entanto, as microestruturas não são idênticas.…”

“…On the other hand, cooling cycles promote de-bonding and tensile failure because of contraction (Kiran et al, 2017). Cirimello et al (2017) explained the concept of drilling with casing (DwC) as an innovative method particularly widespread in deep shale plays, that reduces the time and cost of drilling stages. However, casings are not designed for this purpose, and both the connections and body are required to remain sealed in the well after sustaining a large amount of drilling cycles and possible damage.…”

“…The study examined the failure of a 9 5/8″ diameter K55 seamless casing during drilling an oil well. Fractographic analyses identified fatigue crack nucleation and growth in the tube/coupling (T/C) transition zone (Cirimello et al, 2017). The failure analysis included physical and chemical material tests and numerical stress analyses at the T/C threaded joints when subjected to the loads logged during drilling.…”

“…Pipeline steels are used for the transportation of oil and gas, and are high technology, high value products [1][2][3]. A well-developed system of oil and gas exploitation consists of a series of pipeline steels which joints each other by welding [4,5]. Pipeline steels have an enormous application market in China due to the vast land resources and abundant petroleum resources in China.…”
