PASS

Piping and Equipment analysis & sizing suite

PASS

Start Prof, HYDROSYSTEM, PASS/Equip and Nozzle-FEM are a software suite of NTP Truboprovod.

Start Prof

The world’s first Pipe Stress Analysis Software

START Prof ® evaluates the structural responses and stresses of the different-purpose piping systems at static and cyclic loadings and performs seismic analysis. The first edition of the START Prof Software has been introduced in 1969. Today START Prof ® is the most widely used pipe stress analysis software in Russia and CIS countries, where it has become a pipe flexibility and stress analysis de facto standard for process and power piping, gas and oil transmission, and district heating piping systems.

The world’s first Pipe Stress Analysis Software

HYDROSYSTEM

Nominal Size Selection, Heat Loss & Hydraulic Calculation of Pipeline Systems

The Hydrosystem software performs heat loss & pressure drop calculations as well as nominal size selection for pipeline networks, transporting compressible or incompressible single-phase fluids (gases or liquids), as well as two-phase gas-liquid mixtures. It is widely used in power, oil refining, petrochemical, gas, oil, chemical and other industries. Different parameters of the process piping, main lines, heating and gas-distributing systems and other pipe networks can be calculated using the program. Hydrosystem allows to calculate above ground and underground piping systems of any complexity (including networks with loops). The analysis results can be used for pumps, compressors, control and safety valve selection to ensure the reliability and efficiency of the piping systems.

PASS/Equip

Stress and Stability Analysis of Vessels and Apparatuses Software

The PASS/Equip program is designed for the calculation of stress and stability of vessels, apparatuses and their elements for the purpose of evaluating carrying ability in operating conditions, as well as during the assembling process and testing. The program is created for designing, revamping and testing of vessels and apparatuses, as well as for making check calculations of oil-refining, chemical, petrochemical, natural gas, petroleum and other related industries. The basic PASS/Equip module calculates stress and stability of horizontal and vertical vessels and apparatuses in accordance with Russian normative documents and ASME VIII Div. 1 code.

Nozzle-FEM

Analysis of stress state, calculation of flexibilities and allowable loads of nozzle junctions

Nozzle-FEM is designed for stresses and flexibility calculation of nozzle-to-shell junctions using the Finite Element Method (FEM). The program also calculates nozzle’s allowable loads and estimates strength of the nozzle’s junctions for wide range of geometric configurations and operating conditions. Nozzle-FEM helps to provide higher level of the equipment safety along with reducing labour costs at the design stage. The program is recommended for designing and industrial safety review of oil and gas, refining, petrochemical, chemical, power and other industrial facilities. Unlike the universal FEM programs (ANSYS, NASTRAN, COSMOS, etc.), this program does not require special training and can be used by any mechanical engineer.

Intermarine Shipyard tests Flownex SE for its naval piping systems

Software found to save time in the design phase

This technical article describes a comparative study that was undertaken by Intermarine, with the assistance of EnginSoft, between using the Flownex simulation environment and Intermarine’s manual or classic methods (both of which were compared with actual field data from on-board measurements) to predict pressure losses in the various piping systems that convey fluids on board a vessel.

Trapped-vortex approach for syngas combustion in gas turbines

3D Computational Fluid Dynamics analysis reveals ideal placement for the inlets to create the energetic vortex

This technical article presents a study to design a device that operates entirely on the principle of trapped vortices that intrinsically improve the mixing of hot combustion gases with fresh mixture, a characteristic that is essential both to diluted combustion and to Moderate or Intense Low-oxygen Dilution (MILD) combustion.
