• Entering Nozzle General Data

Nozzle page contains the most data value in PVManage software. We also have the most number of subsidiary pages on this page. The simplicity of the form is maintained in order to avoid the large amount of complexity and density in the subsidiary forms. However, inserting the subsidiary data is considered through certain measures, as well. Intelligent manner of controlling inter-related data is one of the most important factors taken into account in designing this page. It is applied in 6 types below:

 

Size x Rating                        Standard x Size

Size x Schedule                   Standard x Facing

Size x Type                          Standard  x Type

 

This means that in case you choose an option from each field, other fields will be adjusted in such an intelligent manner that unreliable data (data which do not exist technically) will be blocked. As an example, suppose that you have chosen a nozzle’s size and standard as follows. Since there is no size 2″ in API-605 standard, you will not be able to choose the rating and thus unreliable data will be blocked.

Fig. 55 – (Unreliable Data Blocking on Nozzle Page)

  • Defining Nozzle Attachments and Accessories

The majority of fields on this page are selective and unreliable data are blocked, considering the clarifications presented above. Completing the Roll Margin for nozzles made of plate is a fine detail to be taken into account. (For more information refer to chapter 5). Following entering nozzle general data, you can either save them or specify the respective nozzle’s attachments and accessories, prior to that. Keep in mind that in case you intend to introduce or alter the attachments and accessories of a nozzle data after saving them, you have to transfer the data to Field area by double clicking on one of its data in Grid area so as to create the possibility of change.

Choose the intended option(s) one by one through the Attachments drop down list afterwards.

Fig. 56 – (Choosing Nozzle Attachments and Accessories)

 

It is reminded that only one option can be selected between Reinforce Pad and Self-Reinforce; the list above is adjusted automatically with regard to the data within the fields. We use the Attachments sliding list merely to add and remove nozzle attachments and accessories. Each option is elaborated on regarding their technical usage.

 

  • Blind Status

Choose this option if the respective nozzle includes Blind Flange or Manhole and needs Blind flange choosing this option activates the subsidiary menu below and you are to click on Add Blind to register it in the software. In future uses, likewise, you have to refer to this menu in case you intend to remove the Blind.

Fig. 57 – (Blind Flange Addition and Removal Subsidiary Menu)

Having added Blind Flange for a nozzle, required gasket, bolt & nut in proportion to the nozzle size are added to the program, leaving no need for entering their data. Setting the material for gasket, bolt, and nut will be explained later on.

 

 

 

  • Internal / External Pipe

In case the respective nozzle has sunk into the vessel and it denotatively has an Inward Projection, or if it has an unusual length which prevents it from being considered a Nozzle Projection, you will have to use the aforementioned menu.

Fig. 58 – (Internal/External Pipe Addition and Removal Subsidiary Menu)

 

If you click on Default on this menu, Size, Schedule, and Material of the respective nozzle will be transferred and you are not required to enter them; you are merely to enter your desired length. This length will be considered in all material estimate and Part List calculations. Once having clicked on Save Data, you will see the weighs for the added pipes as well as a message containing the successful data saving.

 

  • Reinforce Pad

If the respective nozzle has Reinforce Pad, you must use the aforementioned menu. Choosing Default, a Pad with an external diameter two times that of the standard nozzle outside diameter along with an internal diameter equal to the external one plus related materials (as mentioned in chapter 5 concerning Material Index) will be included, and you are only required to enter the thickness of the respective Pad.

Fig. 59 – (Reinforce Pad Addition and Removal Subsidiary Menu)

 

 

  • Self-Reinforce

You must use the menu below if your nozzle is a Self-Reinforce one.

Fig. 60 – (Self-Reinforce Addition and Removal Subsidiary Menu)

 

  • Vortex Breaker

If your nozzle has Vortex Breaker, you must use this menu to insert its data. Choosing Default, two pieces of plate with equal length and width one and a half times that of the respective nozzle’s diameter and a thickness of 10 millimeters plus related materials (as mentioned in Chapter 5 concerning Material Index) will be included.

Fig. 61 – (Vortex Breaker Addition and Removal Subsidiary Menu)

 

 

After specifying each nozzle’s attachments and accessories on the right side of the Grid, related options will be checked.

Fig. 62 – (Checking Each Nozzle’s Attachments and Accessories)

This section has a decorative function and you are to use the menu in Attachments to remove each case. However, you can classify them by using Filtering Tools.

Each attachment and accessory added to the nozzle enjoys its own specific dimensional data and material. To view these data, right click on each record and choose the desired option.

Fig. 63 – (Activating Attachments and Accessories Dimensional Data Menu)

 

You can view each options technical data by choosing it.

Fig. 64 – (Viewing Technical Data for Each Nozzle’s Attachments and Accessories)

 

 

You are not able to alter these data since they are attached to the main nozzle. You are, however, able to alter its materials by double clicking on the respective record. In this manner, you can apply and save your desired changes.

  • Entering Nozzle Projection On Shell Data
  • No Offset

Clicking on Nozzle Projection, activates the respective menu, depending on the nozzle location defined at the time of data registration.

 

Fig. 66 – (Data Insertion Menu for Nozzle Projection)

If you intend to calculate the nozzle’s length via the software, you must click on Calculate after inserting the data so that the nozzle’s length is calculated. In case the data you enter are wrong regarding their dimensions, warning addresses the length calculated for the nozzle and its registration (which is done by clicking on Transfer Data) will not be allowed!

Fig. 67 – (Impossibility of Inserting the Wrong Length for Nozzle Projection)

 

You are allowed to insert the nozzle’s length manually. This issue appears as a subtitle to show that the nozzle’s length is adjusted by the user.

  • With Offset

If your nozzle is an Offset, you can change its amount using the Nozzle Location drop down list.

Fid. 69 – (How to Insert Data for Nozzle Projection with Offset)

 

Here, you have the authority to insert the nozzle’s length manually, as well.

 

 

  • Entering Data for Nozzle Projection On Head
  • On Ellipsoidal Head

 

Offset can be specified for inserting the nozzle data on Head, too. The menu for inserting the nozzle data changes according to the type of Head on which the nozzle stands.

  • On Body Flange

  • On Hemispherical Head

  • Tips on LWN Nozzles

LWN nozzles are usually produced in standard lengths (generally 9 inches). If required in longer lengths, these nozzles are fabricated with greater expenses. This issue is not taken into consideration in equipment technical data sheets, and turns into a predicament in engineering and equipment fabrication stages. Your knowledge on the longer length of the nozzle in comparison to its standard size can facilitate this process and warn you to be attentive how to resolve it. This Warning appears in PVManage software once you have entered data on Nozzle Projection:

 

 

Fig. 73 – (Warning on LWN Nozzle’s lengths more than Standard Length)

 

This warning stays with you through all stages (estimating materials and preparing fabrication drawing tables). (Details of its appearance will be elaborated on when appropriate).
