TDWIN™ – Thread Disk Software for Straight Thread DimensionsTDWIN-Logo

The Thread Disk™ engineering software (TDWin™ ) calculates critical dimensions for threads based on ANSI tables and formulas. Thread types supported by the program include: UN, UNJ and UNR Series, Acme, Stub Acme, Stub Acme Modified I and II, Metric M & MJ, 7° X 45° Buttress, and General Purpose Pipe Threads.

To generate critical dimensions instantly, enter basic thread information on the Thread Type Entry screen, such as: thread type, thread class, nominal diameter, and threads per inch. Once the results are computed, tabs at the bottom of the program allow selection of several types of calculated information, including dimensions and tolerances for product threads, ring gages, set plugs, plug gages or Gagemaker’s Thread Diameter gages.

If measuring internal and external shallow taper diameters is a problem, the Ball mic SET DIM Tool provides setting dimensions for ball micrometers or Gagemaker’s BX-1000 groove gage. The program calculates ball mic settings for any tapered surface geometry.

Other features of the program include the ability to print thread dimension reports, providing a paper copy of any calculation. These reports provide the same critical dimensions that display in the program. A multiple calculation window capability is a feature that allows performing several different thread calculation at the same time.

TDWIN Taper™ -Thread Disk Software for Tapered Thread Dimensions

TDWIN-Taper-LogoGagemaker’s TDWIN Taper™ software simplifies the API specifications that control connection quality. TDWIN Taper produces dimensional drawings and inspection data for API downhole tubular connections based on the most current industry standards. All the necessary details to machine, inspect and document tubular connection threads are available in one convenient program.

TDWIN Taper provides easy access to information for both preferred and non-preferred Rotary Shouldered Connections, Tubing and Casing Connections, and any combination of Crossover. The program offers standard connection types and sizes. TDWIN Taper™ relies on API and industry standard tables and tolerances. It displays connection drawings, inspection gage information, and setup and inspection reports.

The software displays printable drawing suitable for manufacturing. The drawings follw ASME Y14.5 standards for industry compatibility. Print gage setup and inspection reports with your company logo and work order information. The program offeres the choice to save reports and jobs for future references.
