Besides, some other improvements are included.

NTP Truboprovod has officially released English version 3.80 R4 of «Hydrosystem» software for piping network flow analysis. It includes pressure drop and heat loss analysis and nominal size selection for gas, liquid and two phase gas-liquid frozen and flashing/condensing flow, some cases of two-phase choked flow, possibility to use different metric and imperial units, as well as improved program manual, user interface and result reports in English.

START 4.71 R1 new version is now available. This version has many new features including:

• Added support for Windows 8
• RD 10-249-98: implemented improvement relating to the calculation of non-orthogonal tees
• Added automatic selection of constant hangers and supports by WITZENMANN
• CA 03-003-07: high pressure minimum wall thickness are aligned
• CA 03-003-07: Fixed pressure calculation of tees
• CA 03-003-07: Fixed error in the calculation of the stability of the vacuum pipe
• Fixed an error in the calculation of non-standard restraints containing elastic supports with gaps
• SNIP 2.05.06-85, SP 36.13330.2012: Analysis now taking into account the real stresses due to pressure elongation of pipes and bends
• Window «errors and warnings» are not always appear after the calculation. Fixed
• When you open old files start, inherited as a density of 0. Fixed
• At the large radius bends added linear density and weight of the product

Piping Systems Research & Engineering Co (NTP Truboprovod) has recently joined the Tulsa University Fluid Flow Projects (TUFFP) as part of its strategy to get access to the most modern and reliable data, models and algorithms in the field of piping multiphase flow in order to deliver them to NTP Truboprovod software users.

Piping Systems Research & Engineering Co (NTP Truboprovod) and Institut fuer Energie-, System-, Material- und Umwelttechnik, Bereich Thermodynamik (Institut EMU) at Ruhr-University Bochum (Germany), have reached an agreement, according which NTP Truboprovod has purchased an advanced version of corporate multi-user license of GERG-2008 thermodynamic software, developed by Dr.-Ing. O. Kunz and Prof. Dr.-Ing. W. Wagner at the Ruhr-University Bochum, for usage inside NTP Truboprovod, and has got the right to distribute correspondent libraries as integral parts of its «Hydrosystem», «Safety valve» and «Insulation» commercial software. Press release

Piping Systems Research & Engineering Co (NTP Truboprovod) and the National Institute of Standards and Technology (NIST), an agency of the U.S. Department of Commerce, have reached an agreement, whereby NTP Truboprovod has the right to distribute portions of the latest version 9.0 of NIST Standard Reference Database 23 (NIST Reference Fluid Thermodynamic and Transport Properties: REFPROP) as integral parts of NTP Truboprovod commercial software.
REFPROP is known worldwide as a de facto standard for high precision pure component and simple mixtures physical property calculations for refrigerants, hydrocarbons and natural gas components. The version 9.0 calculates properties and vapor-liquid phase equilibrium for 105 pure fluids, 5 pseudo-pure fluids and their mixtures, including 67 predefined mixtures, most often used in industrial applications.
The agreement makes NTP Truboprovod the first Russian software developer to offer its users the power and accuracy of REFPROP, along with already available STARS, WaterSteamPro and ProSim Simulis Thermodynamics libraries.

ProSim released the new version of Simulis Thermodynamics, which is now available in 3 languages: English, French and Russian. The Russian customization of the user interface was done with ProSim’s partner, NTP Truboprovod. This new version is available worldwide. Simulis Thermodynamics is ProSim’s calculation server for thermophysical properties and phase equilibria calculations on pure components and mixtures. It is available as a Microsoft Excel® add-in, a toolbox in MATLAB® or as a software component which can be easily plugged in any other application requiring reliable and accurate thermophysical properties.
