Shell, Channel & Boot Data
Except for Skirt and Nozzle (which will be elaborated on later), data of each crest-like part, to which one of the titles Shell, Channel, or Boot is applied (whether made of plate or pipe), will be entered on Shell page. To enter the data, first select Data Entering-1 from the main menu and then click on Shell icon.
Fig. 28 – (How to access Shell Data Entering Menu)
In PVManage software, a large number of structures are designed similarly. Therefore, processes explained about Shell page manage to be the same for other pages. If there are any special processes regarding any of the pages’ data entering, they will be explained accordingly.
One of these processes is inserting necessary data as minimums. Entering the following data on Shell page is necessary:
- Item No.
- Material Type
- Shell I.D.
- Shell Th’k
- Shell Length
However, it is not necessary to specify Subject and Material until some stages in the project. If we have entered necessary data, the software can figure the weight calculations and required parts, without considering the part’s material and its subject.
These data can be used up to the time you intend to buy materials and provide MTO. Yet, by the time you intend to buy materials, provide MTO or Part List, you will have to enter the data for the two items mentioned above.
In case you have not completed a necessary field all over the software, and click on either “Save” or “New Part”, that field will turn red and the data registration process will stop.
Fig. 29 – (One of the Software’s Reactions to an Incomplete Necessary Field)
The software will also show reactions to entering unreliable data. As an example, if fields which must be completed necessarily with a positive numerical data be completed with negative numbers or text data, the software will launch a reaction.
Fig. 30 – (An Example of the Software’s Reaction to Entering Unreliable Data)
There is another type of unreliable data which is identified and adjusted automatically by the software. To cite an example, if you have considered “Material Type” from Pipe, “I.D. (mm)” will firstly change to “Size (in)”, “Th’k (mm)” to “Schedule” and Material’s contents to pipe material. Secondly, as soon as you select one of “Size (in)” field’s options (for example 24 inches) in Schedule field, only options related to 24 inch in size will be observed. As a result, entering irrelevant data is impossible by all means!
Material Field’s Intelligent Adjustment
There are two options with regard to material definition in PVManage software.
Fig. 31 – (Material Adjustment Options in the Software)
It is significant to distinguish between the two prior to further discussions.
Material Library is a collection of main materials which completes related fields. For example, there are 50 plate samples as main items in plate group. But, your required and utilized materials in the project might be out of this collection. Each user can add to this collection according to his/her own needs. In this case, added materials are credited in that very username and has no connection with other users (even if they work in one single organization and on one single project). Having said that, contrived materials stay intact in the software library.
Fig. 32 – (Material Library Menu)
Each field in the software, supposed to contain the plate material, will receive its contents from this collection from now on. Thus, any new option’s addition to this collection will spread all over the software.
Material Index is a collection of an item’s constituent materials. If you complete Material Index as you enter the data, material fields will be completed automatically and in proportion to this collection, not requiring to specify the material of a part per its definition. Moreover, you can change every option in its own place. To understand this matter fully, pay attention to an example:
Suppose that plates’ material of an equipment is SA-516 Gr.70 and that of its nozzles SA-106 Gr.B. Besides, take into account that this equipment contains 30 nozzles whose data must be entered into PVManage software. If you complete the Material Index of this equipment prior to entering the nozzles’ data, each nozzle’s material fields and its accessories will be completed automatically as you define the nozzle. Consider the following as accessories of each nozzle:
- Nozzle Material (Pipe / Plate)
- Flange Material
- Blind Material
- Gasket material
- Stud Bolt & Nut Material
- Reinforce Pad
- Vortex Breaker
- Internal / External Pipe
If you have not completed Material Index before, it is required to specify all or some of these items for each nozzle!. This case becomes more complicated when your equipment containing 30 nozzles requires you to specify the material for all the parts per identifying each nozzle.
Not only does this task consume a great deal of time and bore the user, it also increases the possibility of committing errors in data entering. Although there are brisk tools included in PVManage software for duplicating and completing data (which will be introduced later on), we must constantly consider to avoid repetitive tasks and devolve them instead to the software. An example of a completed Material Index is presented in the following figure.
Fig. 33 – (Material Index Menu)
This menu is made of three separate pages and an appropriate tool is predicted in order to complete it in no time. If, as you enter data for an equipment, you enter only the “Shell Material” and then click on the option next to it ( ), all the fields containing the plate will be completed with the same material and you will be able to save all or change some of them.
Suppose that you have an equipment whose shell is constituted of SA-15 516 Gr.70 courses and one of its courses is made of
SA-20 Gr.316 material. In that case, we choose the body material from SA-516 Gr.70 type in “Material Index” menu. Therefore, whenever we define a course of it, material will be completed automatically with SA-516 Gr.70.
However, we are authorized to select the desired material from “Material” field as we define a course with a different material.
This process applies to other subjects, as well. For example, if all “Fittings” of an equipment, except for one, are made of
SA-234 WPB, we select the Fitting material according to
SA-234 WPB when defining the “Material Index” of that equipment; and when defining the excepted data, we are authorized to select the desired material from the respected menu.

This option is an unnecessary field and you can find it on all pages. However, it is strongly recommended to complete it because its existence will prove highly useful and applicable when organizing Part List or Nesting.
