Factors influencing transit fatigue of seamless pipes
(Wiley Blackwell Publishing, Inc, 2005-05)
Full‐scale fatigue tests simulating real pipe stock conditions in ships were carried out in order to reproduce failures of seamless pipes due to fatigue crack growth during shipping. Simple mechanical analyses were then ...
Fracture toughness of high strength seamless pipe steel from SE(T) and SE(B) specimens evaluated by different standards
(Wiley Blackwell Publishing, Inc, 2019-02)
Recently released, BS 8571:2014 standard offers an alternative for the experimental determination of fracture toughness and resistance curves of metallic materials from SE(T) specimens. Similar in stress conditions and ...

Heat treatment is an important seamless pipe production step, utilized to enhance the
properties of the final product such as mechanical strength, hardness and dimensional
accuracy. Quenching is a common step in this ...
Estudo dos processos de amaciamento no laminador contínuo da V&M do Brasil
(Universidade Federal de Minas GeraisUFMG, 2009-04-17)
The seamless pipe rolling presents the oil piping segment as one of its main markets. The oil and natural gas extraction occurs, in great part, in corrosive environments that requires the use of products that present more ...
Failure and integrity analysis of casings used for oil well drilling
(Pergamon-Elsevier Science Ltd, 2017-05)
Drilling with casing (DwC) is 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 still the pipes and ...
