NDT Work Log replaces the time consuming process of writing down all of your work experience hours into a paper logbook with an easy to use mobile phone app. Almost everyone always has their phone on or around them, so for those pursuing a career in non-destructive testing, why carry around a booklet with hand-written work experience hours when you can store it all in your phone instead? NDT Work Log solves that. The NDT Work Log app is a utility application that makes keeping up with your NDT work experience hours as convenient as ever. With a few taps, you can make a work log entry in seconds for 11 different NDT methods. Make that entry as thorough as you like with options to include pictures, work order numbers, part numbers, and any extra notes for reference. The app then adds up all of your total hours in each method and then compares it to the NDT requirements for certification. It lists the hours required, the hours that you have completed, and how many hours remain as you enter job entries and work hours into the log. This information can be shared through email to supervisors, employers, or the technician with options to create reports in Excel Spreadsheet, PDF, and Text File formats that can be downloaded and stored for records. Features: Easy and intuitive interface Choose from 11 NDT methods Make entries as thorough as you like Automatically adds total hours to show your progress Create reports in PDF, .txt, and Excel formats that can be sent through email *****IMPORTANT INFORMATION***** YOUR NDT WORK LOG EXPERIENCE IS STORED ON YOUR APP NOT ON YOUR PHONE. IF YOU DELETE THE APP, YOU WILL LOSE ALL OF YOUR INFORMATION IF YOU HAVE NOT EMAILED REPORTS TO YOURSELF OR YOUR SUPERVISOR.

Read full description

Nozzle Calculator is a professional engineering and fabrication tool for calculating nozzle orientation and marking dimensions for pressure vessels, cylindrical shells, storage tanks, and dish ends. The app helps mechanical engineers, pressure vessel designers, fabrication engineers, QA/QC professionals, inspectors, and workshop technicians calculate accurate dimensions required for nozzle positioning, orientation, layout marking, and fabrication inspection. It eliminates repetitive manual calculations and provides quick, clear, and workshop-ready results. Included Calculators • Shell Nozzle Orientation Calculator • Dish Nozzle Orientation Calculator Shell Nozzle Orientation Calculate nozzle marking dimensions on cylindrical pressure vessel shells and tanks. The calculator determines: • Shell Outside Diameter (OD) from OCF • OCF per Degree • OCF for a Selected Nozzle Angle • Nozzle Orientation Marking Dimensions These calculations are useful when transferring nozzle orientation information onto cylindrical shells during fabrication and inspection. Dish Nozzle Orientation Calculate nozzle arc distance and orientation dimensions on pressure vessel dish ends. The calculator supports common pressure vessel head geometries: • 10% Torispherical Head • 2:1 Ellipsoidal Head • Hemispherical Head Enter the required dish geometry and nozzle orientation information to obtain the calculated arc distance and related marking dimensions. Features • Shell nozzle orientation calculation • Dish nozzle orientation calculation • OCF calculation • OCF per degree • Nozzle angle calculation reference • Dish end arc distance calculation • Pressure vessel nozzle marking • Cylindrical shell layout calculations • Supports common dish end geometries • Metric and Imperial unit systems • Automatic internal unit conversion • Fractional Imperial input support • Clear and meaningful output values • Simple professional interface • Fast engineering calculations • No internet connection required Applications Nozzle Calculator is useful for: • Pressure Vessel Fabrication • Storage Tank Fabrication • Process Equipment Manufacturing • Cylindrical Shell Layout • Dish End Fabrication • Nozzle Installation • Vessel Inspection • Fabrication Layout • Industrial Equipment Manufacturing • Plant Maintenance Designed For • Mechanical Engineers • Pressure Vessel Engineers • Design Engineers • Fabrication Engineers • Production Engineers • QA/QC Engineers • Inspection Engineers • Fabrication Supervisors • Workshop Professionals • Vessel Fabricators • Engineering Students Nozzle Calculator helps reduce manual calculation work, minimize layout errors, save fabrication time, and improve accuracy when marking nozzle positions and orientations on pressure vessel shells and heads. Whether you are working on a cylindrical shell, storage tank, torispherical head, 2:1 ellipsoidal head, or hemispherical head, Nozzle Calculator provides a convenient engineering tool for nozzle orientation and fabrication marking calculations.
