Bentley® AutoPIPE Nozzle is a stand-alone, engineering application used for calculating local stresses at nozzle/vessel junctions, trunnion attachment points, clip connections and lug attachments on the vessel shell. Based on well-known engineering design standards like WRC, KHK, API and PD, AutoPIPE Nozzle helps engineers and designers quickly determine whether or not the wall of a pressure vessel, exchanger or tank can withstand piping loads on the nozzle or at clip and lug connections.

Hollow Round - A round attachment which penetrates through the shell. Examples : Round Nozzle welded to a vessel
Solid Round - A round attachment which does not penetrate the shell. Example: Round hollow Trunion or solid round lifting lug attachment to the vessel shell.
Solid Rectangular - A rectangular attachment which does not penetrate the shell. NOTE : The attachment may be square (equal length and width). Examples: Square support lug or bracket on the vessel.
Hollow Rectangular - A rectangular attachment which penetrates though the shell. NOTE : The attachment may be square (equal length and width). Examples : Square Nozzle welded to a vessel
Shell Deflections, rotations and stiffness values are calculated for all shell types in accordance with PD5500 Annex G for longitudinal, circumferential and radial loadings.
Maximum allowable loads calculated.
Automatic load and geometry links to Rebis pipe stressing program - Autopipe for Windows.
The shell may be specified by either inside or outside diameter or built-in nominal pipe sizes up to 36”. Nozzles may be specified by built-in nominal pipe sizes up to 36” or outside diameter and thickness. Internal shell corrosion allowance may be specified.
The program has built-in standard unit files - English, SI, Metric and Mixed-metric or the user can create customized unit files.
The user can analyze multiple load cases eg 3 thermal, 3 seismic, 3 wind and 3 User-defined cases in the same run.
Automatic load combinations which can selected or de-selected including seismic and wind cases.
Option to include pressure thrust in the deadweight case.
Automatic conversion of local X, Y, Z axes loads to the selected design code axes system.
Extensive material libraries for ASME VIII Div I, Div II and PD5500 with automatic design stresses.
New 1998 ASME VIII code case 2290 material library.
Material selection filters by material (e.g. carbon steel, high alloy , high chrome, copper, aluminum, nickel & titanium) and section (e.g. plates, pipes, forgings, sections & bars and castings).
Analyze oblique or hillside nozzle configurations.
Vessel /Nozzle orientation screen
PD5500 deflection and nozzle stiffness calculations.
Option to enter loads at an external projection from the shell wall e.g at a nozzle flange.
Sorted Stresses on the load combinations.
Defined project details for QA reports.
Extensive On-line context sensitive help.
Print preview capability .
Extensive warning messages if parameters are exceeded - calculations proceed at the parameter limits
Important Note: The following prerequisites are required to run the application:
- Windows NT 4.0 service pack 3 or later.
- Windows 95, 98
- Windows 2000
Internet Explorer 5.0 (or newer), MDAC 2.5 (or later), DCOM 95 (Win95 only)
Before you install any software, you should confirm that you have adequate hardware and software capabilities to install and use the product.
Start Windows, then execute the web download object WNZ3x.exe, the setup program should load automatically.
Press Next from the Introductory screen, then Install Software from the subsequent dialog.
Select the WinNozl program option, then follow the instructions as they are presented on-screen to complete the installation.
Review the README file, which may contain updates and information related to WinNozl not available at the time this documentation was written.
Network drives are not supported for the software and data files.
WinNozl must be installed locally on each client under a WinNozl program directory e.g. c:\winnozl
AutoPIPE Nozzle data files (*.NOZ) must have full read/write access and can only be accessed from a local client workstation.
Multiple users cannot share the same directory on the network. Further, all WinNozl files in the WinNozl program directory must have both read and write privileges for WinNozl to function properly.
WinNOZL requires a hardware lock.
Program Help: Detailed feature information may be accessed directly from the calling application by selecting the Help command, or by pressing the Help button from any of the application dialogs. Be sure to explore the program Help for answers to your questions.
Documentation for WinNOZL applications is provided online in the CHM format. These files are accessible from the Help Menu and can be browsed, searched, or printed.
Reference the OPEN ERROR report for full details related to the errors known to exist at the time of the 3.0 commercial release date shown above. Continuing error reports are provided on a quarterly or monthly basis with client participation in either the "MES" or "QA & Reporting" services.
