1. Introduction

ES_PipeIso is a sub-program to generate a *.pip file which includes the iso-metric information of a piping system, such as pipe diameters, thickness, co-ordinates of piping nodes, kinds and numbers of valves and fittings, etc.

ES_PipeIso has been designed for input of single way of piping flow and not designed for net work piping.

 

2. Major Screens

2.1 Pipe Screen

 

Pipe screen consists of [Pipe List] frams, [Pipe Data] frame, [Node Data] frame and [Total PipeIso Information] frame.

2.1.1 Pipe List Frame   (TOC)

[Pipe List] is the list of pipe names which consists of pipe sequential no., pipe ID, pipe length and pipe elevation difference between inlet and outlet.   The pipe names of [Pipe List] are given by the program automatically and can not be edited by users.   The sequential no. starts from 1 and the pipe elevation difference shall have plus sign when pipe outlet elevation is higher than inlet.

When user starts [ES_PipeIso] program with a new file, #1 pipe is automatically provided with default zero length pipe data.   Additional pipe can be added by user by using the command buttons on the left side of [Pipe List] text box.   [Insert_Aft] button is used to insert a pipe after the pipe currently shown in [Pipe List] text box. and [Insert_Bef] button is used to insert a pipe before the pipe currently shown.   [Delete] button is used to delete the pipe currently shown in [Pipe List] text box.

 

2.1.2 Pipe Data Frame   (TOC)

The upper text boxes shows pipe ID, schedule, thickness and pipe OD of current pipe.    The data of these boxes can be edited only by [Pipe Sel ..] command button.

Clicking of [Pipe Sel ..] buttons activates [Pipe Selection] window, in which a pipe can be selected from built-in pipe data base or manually input by user except pipe schedule.   The built-in pipe data base includes commercial pipe data from 1/8 in. through 48 in. and pipe schedules of commercial and stainless steel according to ASME/ANSI B36.10 and B36.19.

The lower text box is for input by user of absolute roughness of pipe.   The program automatically inputs the value of commercial steel pipe(0.0457 mm) whenever a new pipe is added.

2.1.3 Node Data Frame   (TOC)

In [North], [East] and [Up] text boxes, user  can input or edit the inlet and outlet node co-ordinates of current pipe as well as pipe length and pipe elevation difference.

A node in ES_PipeIso is specified by three co-ordinate system, i.e. north, east and up.   North co-ordinate represents the location in north and south direction; east co-ordinate represents east and west direction; and up co-ordinate represents up and down direction.    

If user changes the node co-ordinates of a pipe in the middle of a piping system, the program automatically changes the node data of remaining pipes so that the length of remaining pipes are unchanged.   However, the node co-ordinates of all pipes at the side of the varied node shall be deviated by the amount the node co-ordinates changed, likely that all pipes at the side of the varied node are moved in parallel by the amount the node co-ordinates changed.

[Node Name] text boxes are to input or edit node names user want to designate the node and may be printed on the iso-metric drawing windows if user selects as such in [Set]-[Graph Output] menu of each main program.

[This pipe length] and [This pipe elevation diff.] text boxes are to show the length  and elevation difference of current pipe calculated by the program automatically based on the node co-ordinates input by user.    User may input or edit the [This pipe length] and [This pipe elevation diff.] text boxes for himself.    If user input or edited [This pipe length], the program automatically changes north co-ordinate of current pipe by the length amount, while up co-ordinate is changed automatically by the program if user input or edited [This pipe elevation diff.].

 

2.1.4 Total PipeIso Information Frame   (TOC)

[Total PipeIso Information] frame shows the aggregated total pipe length of piping system and the elevation difference between the inlet and outlet ends of piping system.

 

2.2 Fittings/Valves Screen   (TOC)

 

[Fittings/Valves] screen consists of [Fittings/Valves List] frame and [Fittings/Valves Selection Table] frame.

2.2.1 Fittings/Valves List Frame   (TOC)

The list box of [Fittings/Valves List] frame shows the list of fittings and valves of current pipe and the list can not be edited.   [Q'ty] text box shows the quantity of the fitting or valve selected in the list above and the quantity can be changed by user.   The remaining two text boxes next to [Q'ty] text box are to show other design parameters of the fitting or valve selected in the list above and the parameters can be changed by user.   The other design parameters include the values of diameter ratio[Beta(ß)], divergence or convergence angle[Theta(?)], bend ratio[r/d], etc.

[Delete] command button is used to delete the fitting or valve selected in the list above.

2.2.2 Fittings/Valves Selection Table Frame    (TOC)

This frame is used for user to select a fitting or valve to added to current pipe and listed into the [Fittings/Valves List] at left side.   When user selects a fitting or valve in the menu, [Add] command button becomes visible and is used to add the selected fitting or valve to current pipe.  [Cancel] command button is used to disable current selection.

A reducer or increaser can be added to pipes only by differing the nominal pipe diameters of adjacent pipes and can not be added arbitrarily by user.    [Reducer] command button at the top of this frame is to give such information message only.    When being included between two adjacent pipes, the reducer or increaser is located at upstream pipe.

 [User Defined Fitting] command button at the bottom of selection menu is used to add a fitting with user-defined pressure drop(dP) or flow resistance(K) value.

2.3 Graphic Screen    (TOC)

 

The graphic screen shows iso-metric drawing of current piping system including node numbers, node co-ordinates, node names, etc.   (TOC)
