  • Piping arrangement drawings sections and elevations
    2012
    Co-Authors: Roy A. Parisher, Robert A. Rhea
    Abstract:

    The Piping-arrangement drawing evolves from the foundation location and equipment location drawings. It shows all mechanical equipment and vessels in the unit and the pipes connecting them—including manholes, ladders, platforms, and davits. It identifies all structural supports such as pipe racks, equipment structures, columns, braces, and any fireproofing they may have. Once locations for foundations and equipment are established, Piping configurations are added to the drawing with the aid of symbols that represent fittings, flanges, and valves. The arrangement drawing is the most significant drawing developed by a Piping designer. This plan-view drawing is a major source of information used in the fabrication and erection of the Piping Facility. Information on the arrangement drawing aids in the development of the Piping model and the isometric drawings. Good dimensional arrangement and placement enhance a drawing's effectiveness. Clear, concise, well-placed dimensions not only reflect a well-thought-out drawing but also simplify communication, which minimizes checking and reduces drawing revisions.

  • automate dummy variable creating from large longitudinal rdbms tables a pedagogical example of the sas connect Piping Facility
    2009
    Co-Authors: Melissa Skanderson, Xiaoqiang Wang
    Abstract:

    Given a list of patient demographic characteristics and the patient lab records in RDBMS tables separated by years, we can create a list of summary variables per specification per person almost automatically using 3 parallel processes: process #1 selects all lab records only for the patients in our ID list and writes them into pipe #1; process #2 reads records from pipe #1, cleans lab results into appropriate numeric values and writes them into pipe #2; process #3 reads lab values from pipe #2 and aggregates them into person-level characteristics. Tricks of SAS/Access for OLEDB, regular expression, Hash object, and macro programming are illustrated too. We also discuss the advantages and limitations of our methods. This paper fills in the gap of the lack of a working example on the Piping Facility.
