First introduced in 1969
Russian piping code stress analysis de facto standard

Version History


START Prof evaluates the piping stress from pipe thermal expansion and other loads including seismic, pipe support loads according to Russian, ASME and Chinese codes. The first edition of the START Prof software has been introduced in 1969.

Today START Prof is the most popular pipe stress analysis software in Russia and CIS countries. It has become a pipe stress analysis de facto standard for process and power piping, gas and oil transportation systems, and district heating piping systems and hot water piping in Russia and CIS countries.

START Prof is used by more than 1500 companies in Russia, Ukraine, Belarus, Kazakhstan, Turkmenistan, Uzbekistan, China, Japan, Lithuania, Czech Republic, Serbia, Finland, Germany and United Kingdom. The total number of the licenses exceeds 8000. START Prof is widely used by major plants and design companies in chemical, oil & gas, power, metallurgy and other industries.

START has a Russian, English and Chinese user interface, user guide and help system.

Due to ongoing feedback from a lot of users, cross-testing with other software, quality assurance system, it is well verified. Every new version passes quality assurance testing with more than 200 special verification models.

The START Prof Software is fully certified according to Russian standards.

System requirements: Windows 7/8/10, IA-32 or AMD64/EM64T processor, Memory 1Gb and more, Graphics card with OpenGL 2.0 or higher, support NVIDIA or AMD/ATI, recommended NVIDIA GeForce 7000 or higher or Radeon X300 or higher with 1Gb or more memory.

Codes and Standards

  • Plastic piping stress analysis (HDPE piping): GOST 32388-2013

The following types of pipelines are covered:

  • Above-ground piping, underground and buried pipeline
  • Above-ground, underground and buried pipelines
  • Branched and closed contour pipelines
  • With different types of expansion joints
  • With various types of restraints and boundary conditions
  • With different external loads (thermal expansion, dead weight, pressure, concentrated and distributed forces, supports displacement, hanger settlement, pre-stretch, etc.)
  • Operating at low and high temperatures. For high temperature pipelines the creep and stress relaxation effects are analyzed

  • "Soils": includes mechanical and physical properties of soils for buried pipelines modelling
  • “Flexible joints”: includes properties of axial, gimbal, lateral flexible joints
  • "Insulation": includes insulation weight values depending on the insulation structure, temperature and pipe diameter

START-Elements — Piping Design Software Tool

Besides analysis of arbitrary configuration pipelines, we have implemented a working tool along with piping handbook for a piping designer — a START-Elements option. Start software is designed for rapid flexibility estimation of piping fittings, their strength and stability analysis. Using START-Elements, one can do the following:

  • Analyze stress of L, Z and U-shaped piping loops (buried and above-ground)
  • Pipe and fitting wall thickness calculation or maximum pressure according to the code selected
  • Calculate maximum allowable distances between supports via strength and stiffness analysis
  • Check general and local stability of straight and curved pipe elements under the thermal expansion, external pressure (vacuum) and soil pressure loads
  • Calculate minimum pipeline laying depth for buried pipelines using stability analysis
  • Calculate maximum pipeline laying depth for buried pipelines by polyurethane insulation stress analysis
  • Calculate allowable load on saddle support for large-diameter pipes
  • Calculate allowable distances between single action (one time) compensators and their closing temperature
  • Calculate bellows stiffness if the manufacturer’s data are absent
  • Check leak tightness of flange joints
  • Centrifugal pump load check per API 610 (ISO 13709), GOST 32601-2013 and Kellogg method (L.C. Peng Pipe stress engineering)
