PASSAT Design calculations for vessels and apparatus forstrength and stability

The PASSAT is used to calculate the strength andstability of vessels, vehicles and their components in order to assessthe carrying capacity in the working conditions, as well as in terms of testingand installation

The program is designed for use in the design, reconstruction anddiagnostics of vessels and vehicles, as well as during testing calculationsobjects refining, chemical, petrochemical, gas, oil and other related industries PASSAT - advantage compared with similar programs is to focus on theRussian legal framework, a lower price, intuitive measuring, built-in database

 

Basic PASSAT

Calculates the Strength and Stability of Horizontal and Vertical Vessels and Equipment on Domestic Regulations (ND)

Calculation is carried out both on the basis of the collection as the last

GOST R 52857 (1-12) -2007 - GOST 14249-89 preceding it, GOST 25221-82 ,- GOST26202-84 GOST 24755-89-RD 26-15-88 - RD RTM 26-01-96-77-RD 10-249-98-OST 26-01-64-83

RD 26-01-169-89-RD24-200-21-91

PASSAT-Columns  

Calculation of the strength and stability of the column based on wind loadsand seismic actions Calculation is based on GOST 51273-99, GOST 51274-99

PASSAT-Heat  

Calculation Of The Strength And Stability Of Shell And Tube Type HeatExchangers And Air Coolers (Air-Cooling) On The Basis Of GOST R 52857.7-2007, RD26-14-88, GOST 30780-2002.

PASSAT-Seismic

Calculation of the strength and stability of horizontal and verticalvessels taking into account loadings from seismic effects available based SRT-CA-03.003-2009 ,Vessels and vehicles. Limits and methods of strength calculation for seismiceffects

PASSAT Tank

Calculation of the strength and stability of the vertical steel cylindricaltanks on SRT-CA-03-002-2011 , including from wind, snow and seismiceffects

PASSAT-fitting

An additional feature is the calculation of tie-in fitting shells anddished ends, flanges and reinforcing effects of pressure and external loads ontraditional American and British documents. The calculation is based onthe rules based on strength equipment ASME SEC.VIII, ASME SEC.II, WRC-107,WRC-297

Input Data

Type-material - geometrical characteristics of the elements or of thevessel device, the type and arrangement of bearings, test type, the magnitudeof loads

Feature selection is made ​​ from the materials database, which may be adjustedor supple mented by theuser. Results of calculation are given in the form of a comprehensivereport on the elements of the model with all the intermediate results ofcalculations derived in MS word format furnished by ESKD

PASSAT Advantagecompared with similar foreign programs (compress, vessel, pv elite, etc.) Is tofocus on the russian legal framework, a lower price, intuitive measuring,built-in database of Russian materials.

When you create a model can be used embedded database standard elements -shells, heads, bearings, flanges, gaskets and other databases of materials andcomponents are open and can be replenished by the user.
