The Elite Software D-Pipe program quickly calculates optimal pipe and vent sizes for sanitary building drain systems with a virtually unlimited number of pipe sections. Existing drainage systems can also be analyzed because D-Pipe allows the designer to fix the size of any and all pipe sections. Besides sizing reports, D-Pipe can also print a complete bill of materials showing both labor and material costs. Branch, sewer, and stack pipes along with branch and stack vents are automatically sized in accordance with the UPC or IPC code. D-Pipe also has provision for sizing pipes using codes different from standard. In fact, you can define and maintain as many sizing code files as necessary. D-Pipe is very easy to use as it contains built-in data concerning fixtures, pipe materials, and pipe fittings. D-Pipe does allow the user to maintain various material files, and each material file can contain up to 96 different fixtures, unlimited pipe fittings, and 60 material types.

Two types of data are requested: general project data and pipe segment data. The general project data includes the project name and location, building drain and main sewer elevations, the maximum and minimum allowable pipe sizes, and the default pipe material. The pipe data requires that each pipe section be defined as having beginning and ending node numbers along with a type specifier such as branch, stack, sewer, branch vent, or stack vent. In addition, the length, material type (cast iron, copper, steel, PVC, etc.), fitting quantities and types, and connected fixtures must be specified for each pipe section. For designers who do not want to specify detailed fixture information, there is an option for entering a direct drainage fixture unit (DFU) value for each pipe section. Options are provided to quickly view, edit, add, or delete pipe sections. Input sheets are provided for the easy organization of your data.

The D-Pipe program can import a drainage piping system drawn in a .dwg file saved with Autodesk Building Systems 2006. Importing the pipes for your system saves considerable manual input time. If the drawing has been saved with the Elite piping .dwt template file included in the D-Pipe installation, node number tags will be placed on the drawing as shown in the example ABS screenshot below. After you run D-Pipe calculations, you can then export the results back to ABS 2006. You can right click a pipe, fitting or fixture in the drawing and view the calculated fixture units, water closets and other data in the Engineering Data section of the Design tab of the Object Properties dialog. You can even automatically resize pipes in the drawing based on the D-Pipe calculations.

The D-Pipe Program provides the following four basic output reports: general project data, pipe size data, vent size data, and a bill of materials with complete cost data. In addition to these reports the built-in pipe data, fitting data, and drainage fixture data can be printed.

The D-Pipe Program follows the methodology described in the American Society of Plumbing Engineers (ASPE) Databook and the Uniform Plumbing Code published by International Association of Plumbing and Mechanical Officials, and International Plumbing Code published by Building Officials & Code Administrators International, Inc. As new codes emerge, D-Pipe allows you to easily change the sizing tables. All results computed by the program can be easily verified by hand to be in accordance with ASPE and IPC/UPC code requirements.
