Generally the FBE Coated API 5L X70 PSL 1 is used as a reference for all line based piping API X 70 Grade HR Coils for ERW PipesFeb 02, 2013 · Alloy Design Alloy chemistry was designed not only to achieve the aimed properties of API X 70 HR coils as shown in Table 1 which ensured meeting the end properties required in a API X 70 grade linepipe, but also it ensured that the operating window of steel processing for API X 70 grade is suitable for BSL conditions of steel making, casting and the hot rolling processes.
- AbstractIntroductionMaterials and MethodsResults and DiscussionConclusionAcknowledgmentAPI X70 pipeline steel with a rectangular shape and dimension of 1cm length and 1cm width was employed in this study. The main chemical compositions for this steel were 0.04% C, 1.70% Mn, 0.035% , 0.035% , and 0.55% ; all these elements were in mass percent. Arabian Gulf seawater was brought from the Arabian Gulf at Dammam, Saudi Arabia. The electrochemical measurements were collected using a conventional electrochemical cell with a three-electrode configuration.

Ceria/Acrylic Polymer Microgel Composite:Synthesis Apr 25, 2017 · Ceria/poly(acrylic acid) microgel composite with anticorrosion potential has been synthesized via an in situ polymerization method. This polymer composite matrix has demonstrated significant reduction in API 5L X70 steel corrosion in 0.5 M HCl. In-depth studies of the anticorrosion properties of this microgel have been conducted by corrosion electrochemistry, and its adsorption on
Apr 28, 2021 · API X70 parent material toughness at 20 °C was 281 J. Microstructural variations can be attributed to the reduction in impact toughness with increasing cooling rate. At the higher cooling rate (5062.5 °Cs 1), the microstructure is completely bainitic. However, at slow cooling rate, ferrite dominant microstructure was observed. Development of API X70 Grade Hot Rolled (HR) Coils for May 01, 2016 · In the recent past, API X70 grade HR coils for ERW pipes were successfully developed at BSL based on ferrite-pearlite microstructure having Nb-V-Cr based steel chemistry, where the required tensile properties need to be achieved in transverse direction (at 90°) of the strip.
