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.

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.

Stress and Stability Analysis of Vessels and Apparatuses Software

The PASSAT 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 PASSAT module calculates stress and stability of horizontal and vertical vessels and apparatuses in accordance with Russian normative documents and ASME VIII Div. 1 code.

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.

Dynamic response of a buried pipeline, under the action of the fall of rocks on the soil

Safety assessment of a buried pipeline potentially subject to rockfalls

Oil or gas pipelines that cover long distances pose complex design challenges. Every environment the pipeline crosses is characterized by different potential geohazards. One of the most dangerous for a pipeline is a rockfall.

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.
