WHAT WE CAN DO FOR YOU
ONYX Unlimited provides engineering and consulting services to all industries that have flow accelerated corrosion (FAC)/erosion/degradation concerns in pressure boundaries, with a particular focus on Code compliance issues in vessels, heat exchangers and piping. Design services include application of the patented “PMC Restoration Method”, Flow Restriction Devices (Orifice Plates), ASME pressure vessel design, Fitness for Service (FFS) evaluations, Finite Element Analysis (FEA), mechanical engineering, and structural analysis.
fitness for service code evaluations
ONYX has agreements in place with highly qualified engineering service providers whose services have been used extensively to determine the capability of components with degraded pressure boundary, including localized metal loss and pits, in shells and nozzles, to remain in service while satisfying ASME Code criteria. Our Fitness for Service evaluations determine how long a component can remain in service before repair is required. Evaluations are performed using in-house developed metal loss prediction and Code compliance software, along with detailed finite element methods. Results of our evaluations can allow for continued operation and provide sufficient time to adequately plan for repairs on a non-emergency basis.
MATERIAL SUPPLY
ONYX provides a wide range of materials to energy industries, with its primary business focus on the supply of safety related metallic materials, parts, and components for the commercial nuclear power generation industry. Click here to see what ONYX can provide for you.
FINITE ELEMENT ANALYSIS
ONYX’s engineering service providers utilizes finite element methods to perform component and structure analyses that provide accurate and economical hardware designs and evaluations. Use of finite element methods can reduce the inherent conservatism and provide more accurate stress and factor of safety results than those obtained using conventional hand calculations or design by rule methods. Work is performed using ANSYS and/or NASTRAN finite element analysis software.
ASME SECTION VIII / III FABRICATION
ONYX Unlimited provides ASME Code pressure vessel engineering, design services, fabrication management and inspection services for ASME Section VIII components to the commercial industry and ASME Section III components to the nuclear industry. Code stamped components can be procured from ONYX Unlimited.
