... Abstract The use of metallized coating on bridges in New Hampshire years ago was limited to small special strategic steel locations. The metallizing option was severely limited by lack of shop applicators. Rhode Island pioneered duplex metallized bridges, research, and interest. The past two...

... INTRODUCTION ABSTRACT Metalized corrosion control coatings applied with low energy Big Wire arc spray systems are significantly reducing the application costs of long life coatings. The increased deposition rates and the improved deposit efficiencies achieved with twin wire 3/16 (4.8MM...

... complicated by the presence of metal hydroxides (commonly iron, aluminum, and magnesium hydroxides). The scope of the present study is to explore the effects of the presence of such hydroxides in a process system on silica formation. Introduction The polycondensation of silicate to form colloidal silica...

... by a series of teeth which provide a positive locking mechanism with high torque loading. Non Return Valve (NRV): "An NRV located above each ESP turns the Dual ESP System into an automatic system, which allows alternate ESPs to operate without wireline intervention. Its metal to metal Inconel seal...

...) mainly due to friction between the coiled tubing string and well casing or reservoir formation rocks. To address this, a variety of techniques have been used over the years to reduce the friction between the metallic surfaces and extend the reach of the coiled tubing string to desired depths. Several...

... with numerical simulation, such as Finite Element Analysis (FEA). To facilitate numerical modeling, extensive research work has been performed recently (e.g. Xie, Matthew, and Hamilton (2016) and Xie and Matthew (2017) ) to establish a constitutive relationship for evaluating metal-to-metal sealability...

... carbon steel or low alloy steel base metal weld seams between the cladding materials during original fabrication or for welding repairs made during service. The first part of this paper describes a comprehensive review of the use of 13-17% Cr stainless steel nearly matching filler metals for restoring...

.... The addition of surface topography in the contact simulation allows the introduction of the concept of permeability of the (deformed) gap between the contacting areas of the pin and box of a metal-to-metal seal [ 10 – 14 ]. This permits the definition of a leakage criterion based on permeability instead...

... Abstract API flanges maintain integrity through metal-to-metal seal between gasket and flange groove, where sealability depends on contact stresses through bolt makeup-load, tension, fluid-pressure, bending moment. Approaches like API-6AF2 have limitations. With increased deep-water operations...

... Abstract PetroChina Canada's Mackay River project is currently the largest SAGD operation where Metal to Metal PCPs (MMPCPs) are being used as the primary artificial lift method. Their simplicity and potential robustness in very high temperature applications were considered advantages...

..., synergistically paired metal-filming lubricants and fluid friction reducers provide a cost-effective method to enhance weight on bit (WOB) required while running in and/or pulling out of hole (RIH/POOH) CT strings. Given the dynamic nature of CT operations, carrier fluids experience extreme conditions changes...

... stress profile on the radial seal surface, surface roughness, thread compounds and various other factors such as environmental impacts. This paper presents experimental work that has been undertaken to investigate the metal-to-metal seal behavior in premium casing connections. The physical tests...

... The novel metal-to-metal sealing and anchoring system was designed to set and seal inside the operator's 10.125-in., 81-lb/ft casing and to hang 7.75-in., 46.1-lb/ft liner. The basis of design was the service provider's ISO 14310/API 11D1 V1-Type qualified hanger. Recognizing the previous testing...

...-circulation rate capability Lowest possible pressure drop at liner top Capability for movement of the liner during the cement job High-tensile rating and hang capability Reliable gas-tight liner top seal The new metal-to-metal sealing ELH was designed specifically for this type...

... Abstract The Oil & Gas industry has an increasing demand for gas tight connections, particularly in deepwater applications such as in the Gulf of Mexico. These connections incorporate metal-to-metal seals and have been been motivated by wells requiring high-pressure completions/stimulations...

.... The development of this new premium rotary shouldered connection with a metal-to-metal seal has been first and foremost motivated by the needs of this market segment, specifically to be used in Deepwater hydraulic fracturing operations and managed pressure drilling/underbalanced pressure drilling applications...

... of weldments of available structural steels are insufficient or on the borderline for arctic application down to -60°C, and may thus not give the required robust solutions. Therefore, the present work was initiated to evaluate weld metal toughness based on the use of commercial wires to clarify the need...

... Abstract The poor performance of Metal-on-Metal (MoM) bearings has to date been blamed on "adverse loading" conditions. Studies have focused on the effect of cup inclination and microseparation on gravimetric wear rates and highlighted the importance of surgical technique when implanting...
