Development of Polymer-based Composite Coatings for the Gas Exploration Industry: Brajendra Mishra1; Ali Chaudhry1; 1Worcester Polytechnic Institute
Inorganic oxides can be synergistically beneficial for organic coatings, if it has the ability to impart anti-corrosion ability and as an additive to enhance physical or chemical properties. The aim of this study was to evaluate the anti-corrosion ability of nano nickel zinc ferrite (NZF) in solution and paint film. Anti-corrosion ability of NZF extracts in 1 molar H2SO4 and 3.5 wt % NaCl were evaluated using electrochemical techniques (EC). Time dependent anti-corrosion ability of NZF/chlorinated rubber nano-composite coatings (0.1% -1.0% NZF) applied on carbon steel (CS) were characterized by EC such as open circuit potential (OCP), electrochemical impedance spectroscopy (EIS), linear polarization resistance (LPR) and potentiodynamic (PD). Characterization of corrosion layer was done by removing coatings after 216 hrs in 3.5 wt % NaCl. Optical microscopy, EC data suggests electrochemical activity by metallic cations on surface during corrosion process which results improvements in the anti-corrosion properties of CS.

Where the Polymer Meets the Oilfield: Huilin Tu1; 1Schlumberger
Can you imagine that polymers are at every corner of the oilfield business? I would show you where the polymer meets the oilfield throughout the lifecycle of an oil well. I would highlight the research and development of three types of polymer materials – swellable elastomers, degradable polymers and high temperature polymers, and their unique applications in oilfield.
Mineral Scale Fouling Under Boiling: Fundamentals to Mitigation: Susmita Dash1; Leonid Rapoport1; Navdeep Dhillon1; Kripa Varanasi1; 1Massachusetts Institute of Technology
Scale formation, due to the presence of dissolved salts and organic impurities, poses serious problems in several practical applications, ranging from household utensils to industrial boilers, and affects industries including desalination, oil and gas, and cooling towers. In particular, salts with inverse solubility with temperature have the tendency to crystallize and adhere to the heat transfer surface and adversely affect the thermal and fluid transport. In the present study, we investigate the mechanism of salt crystallization during pool boiling. The boiling performance parameters, such as, heat transfer coefficient and critical heat flux (CHF) are examined for an undersaturated solution of calcium sulfate. Simultaneous high speed and infrared imaging enables determination of the interdependence between crystallization and bubble dynamics, including, bubble nucleation, growth, and departure. The effect of the three phase contact line during bubble evolution on the crystallization-induced scale formation is demonstrated.
Interfacial Engineering for Suppressing Mineral Scale Fouling: Samantha McBride1; Susmita Dash1; Sami Khan1; Kripa Varanasi1; 1Massachusetts Institute of Technology
Accelerated corrosion and salt scaling in energy applications has a destructive influence on the efficiency of power cycles. In many cases, corroded equipment is taken offline for replacement or repair. Many of the currently used corrosion inhibition methods are expensive, time intensive, and/or hazardous to the environment. One possible solution is implementation of omniphobic liquid impregnated surfaces designed specifically for eliminating scale buildup and salt corrosion. Here we demonstrate that lubricant impregnated surfaces (LIS) resist crystallization and delay the onset of scale precipitation. These surfaces are compared to other forms of hydrophobic substrates, including silane coated surfaces and rare earth oxides. Experiments conducted on these substrates of different surface energies and textures also demonstrate the importance of salt composition in controlling solute-surface interactions, and the importance of micro-textures.

Co-relation of Microstructural Features with Tensile and Toughness Characteristics of X70 Grade Steel: Tushal Kyada1; Raghu Shant Jonnalagadda1; Rajesh K Goyal1; Tribhuwan Singh Kathayat1; 1Welspun Corp. Ltd
API 5L X70 line pipe steel grade has been very popular for the pipe manufacturing in sour/non-sour and offshore/onshore applications. This steel is available in various delivery conditions such as controlled rolling and TMCP with or without accelerated cooling. The selection of plate or coil depends on the type of pipe manufacturing and its final application. Co-relation of steel microstructure with tensile and toughness properties before and after pipe manufacturing is required for the selection of steel suitable for a given application. Depending on pipe manufacturing process as per application steel cleanliness, allowance for bauschinger effect, stain hardening, SCC and HIC resistance plays a prominent role. Present work discuss about microstructure and its co-relation with properties for X70 steel plates and coils supplied by 12 steel mills. Evaluation of alloy design with respect to microstructural features and its effect in tensile and toughness properties from plate/coil to pipe is analysed.

Development and Applications of New Generation Ni-containing Cryogenic Steels in China: Zhen-yu Liu1; Meng Wang1; Jun Chen1; Guo-dong Wang1; 1Northeastern University
In the present paper, an overview on the developments and applications of Ni-containing cryogenic steels is described with regard to the manufacturing processes. The relationship among Ni content, processing parameters and formation of reversed austenite has been worked out, which demonstrated that content and size of reversed austenite in Ni-containing steels can play important roles in improving their toughness. Based on extra-dephosphorization and desulphurization, new processing technologies have been developed. Controlled rolling in the aim of microstructure refinement and ultra-fast cooling (UFC) after hot rolling as on-line direct quenching has been successfully applied. Combining with inter-critical quenching and tempering after UFC-TMCP, the reversed austenite content was increased from about 1.8% to about 6.5%, leading to significant improvement of toughness. Several China’s steel works such as NISCO and Angang are capable of manufacturing high quality plates of Ni-containing steels, which are finding wide applications to building extra-large tanks for liquefied gases.
Anisotropic Behaviors for X100 High Grade Pipeline Steel under Stress Constraints: Kun Yang1; Ting Sha2; Ming Yang3; Chen Shang3; Qiang Chi1; 1Tube Goods Research Institute; 2The No.771 Institute of Ninth Academy of China Aerospace Science and Technology Corporation; 3Petrochina West Pipeline Company
Because of the manufacture process of high grade pipeline steel, the anisotropic behaviors appeared in different directions, including both properties and microstructure. In this paper, mechanical properties and microstructures for X100 high grade pipeline steel were investigated with a series of tests, including not only experiments but also simulation. Tensile tests with DIC method was used to get the stress-strain relationship, especially in the process of fracture. SENT tests with different notch sizes were used to characterize the fracture resistance anisotropies. The microstructure was characterized by both fracture analysis and inclusion characteristics to infer the relation between voids growth and crack propagation. Moreover, FE simulation of SENT was carried out by complete Gurson model. Finally, the results of tests and simulations were compared to study the effects of stress constraints on crack resistance in different directions.

Ltd.; 4Shougang Research Insititute of Technology
The research and development of 21.4mm/22mm X80 hot rolled strip in shougang is introduced under industrial conditions. This X80 strip with extreme large thickness has good low temperature thoughness, after pipe making, its DBTT of DWTT is below -30℃. Meanwhile, high microalloy content addition is not adopted to improve low temperature toughness, so the cost is acceptable, and this product of 21.4mm X80 will be applied in the China-Russia East Route natural gas pipeline project. The production of 21.4mm/22mm X80 strip in Shougang focuses on the austenite grain condition optimizating. Based on the complex interaction of precipitation pinning, recrystation and soulte dragging, proper rough rolling process is designed to refine austenite grain homogeneous as much as possbile, as well, finsih rolling process is designed to flatten the austenite grain fully. Moreover, superfast cooling is adopted to inhibit phase transformation in high temperature and refine effective grain size.
