1. A Comparative Investigation of the Corrosion Resistance and HIC Suceptibility of API 5L X65 and API 5L X80 Steels
High strength low alloy (HSLA) steels are used for the construction of pipelines for oil and natural gas transportation. For such applications pipelines must exhibit mechanical resistance and resistance to corrosion and hydrogen induced cracking (HIC). API 5L X65 steels are the main materials used for this purpose. However, for economic reasons, the use of s

2. Evaluation of hydrogen-Induced cracking resistance of the In625 laser coating system on a C-Mn steel substrate
Abstract The corrosion of C-Mn steels in the presence of hydrogen sulfide (H2S) represents a significant challenge to oil production and natural gas treatment facilities. The failure mechanism induced by hydrogen-induced cracking (HIC) in a Inconel 625 coating / C-Mn steel has not been extensively investigated in the past. In the present work, an API 5CT ste

3. Avaliação do fenômeno de união de trincas induzidas pelo hidrogênio e sua influência na integridade estrutural de um vaso de pressão
Componentes e equipamentos utilizados na indústria petroquímica estão suscetíveis a presença de descontinuidades e, por esta razão, diversas pesquisas são desenvolvidas com o intuito de aprimorar e criar novos métodos para evitar, remediar ou controlar estas, de forma a não causarem um dano à integridade estrutural. Neste trabalho é avaliado um co

4. Metodologia para análise de trincas de hidrogênio em soldas através de ensaios destrutivos e emissão acústica / Methodology of Analysis of Hydrogen Cracking in Welding using Destructive Test and Acoustic Emission
The evolution of the processes of welding, registered in recent years in everybody, has occurred had to this process of manufacture to be related with the majority of the industrial applications, either in the construction as in the recovery of components. To this used procedures to evaluate the cracking sensibility in metallic structures comes being constan

5. Environmentally induced cracking of API grade steel in near-neutral pH soil
Environmentally induced cracking of pipeline steels in contact with soil have been investigated. Different soils were prepared in order to determine their physical, chemical and bacteriological characteristics. Slow strain rate testing was carried out by using electrolytes obtained from soil samples and NS4 standard solution. Stress vs. strain curves of API

6. WELDABILITY ANALISES OF API 5L X-80 STEEL USING TEKKEN TEST AND IMPLANT TEST / ANÁLISE DA SOLDABILIDADE DO AÇO API 5L X-80 POR MEIO DOS TESTES TEKKEN E DE IMPLANTE
This work shows a study of the weldability of API 5L X-80 steel using the Tekken Test and the Implant Test. The research analises the weldability of HSLA X-80 steel for orbital circunferencial welding with the Shielded Metal Arc Weld and the Flux Core Arc Weld processes with regard to hydrogen induced cracking formation. The aim is to make feasible different

7. EVALUATION OF API STEEL WELDED JOINTS IN A CORROSIVE MEDIUM / AVALIAÇÃO DA JUNTA SOLDADA DE AÇO API EM MEIO CORROSIVO
The steel tubes used in the Oil Industry are constantly exposed to hydrogen sulphide (H2S) which leads to the diffusion of hydrogen into the steel, provoking hydrogen induced embrittlement cracks and/or stress corrosion cracking. Welded joints, generally considered to be the critical region in pipelines, were evaluated in this study, using slow strain rate t
