Program description

Steady State Calculation of Flow Distribution,
Pressure Drop and Temperature Drop in Branched and Intermeshed Piping Networks

In plant construction stringent regulatory rules require a steady rising effort in documentation. At the same time a higher economic competition demands a continuous rationalization process to shorten the planning times. This requires a tight cooperation of all engineering divisions and a smooth communication is necessary.

Integrated planning systems with specialized components have a central meaning in the project planning. Such a „specialist" is SINETZ, the program for the calculation of pressure drop and heat loss in branched and intermeshed piping networks with circular, rectangular as well as any cross sections, defined by the hydraulic diameter.

Many well-known companies from different industrial branches trust in the quality of SINETZ, among them leading plant construction companies, power station enterprises, local energy supply companies, shipbuilding companies, ventilating system manufacturers, chemical industry, component manufacturers and universities.

Program overview

The tasks of SINETZ are:

  • Dimensioning of cross sections and insulation in the project period
  • Dimensioning of pumps
  • Verification of dimensions for network expansions
  • Usability analysis of existing piping networks
  • Simulation of different operation states or abnormal occurrences in intermeshed piping networks

SINETZ solves the tasks by calculation of pressure and temperature loss in branched and intermeshed piping networks with circular, rectangular as well as any cross sections, defined by the hydraulic diameter.

SINETZ calculates direction of flow, rate of flow and temperature loss for individual pipe sections, as well as the temperature and pressure of individual nodes, and the resulting flow distribution for an intermeshed system of any complexity. Calculations for compressible and incompressible media are both possible.

Different from SINETZ, the capabilities of SINETZfluid do not include the calculation of compressible media and temperature loss analysis.
The calculation is carried out for a given system assuming a steady state flow. Arbitrary intermeshed networks are solvable. Calculation is possible for open as well as for closed systems.
 

System geometry

The system has to be divided into pipe sections. A pipe section consists of a pipe segment with a constant diameter without branches. The calculation parameters are entered by means of a graphical interface. The system geometry is drawn by the mouse, additional values like segments lengths, node height, components and boundary conditions are added by dialog windows and mouse input.
The program user is supported by integrated expandable databases.
The program determines the resistance coefficients for some components basing on the geometry and flow state.
The inputs are shown graphically including different symbols for instruments.

Various operating states of the system may be simulated by load case input.

User support and training

The SINETZ system contract includes a qualified user support during a period of six month after purchase.
In order to boost the efficiency of the SINETZ users, SIGMA proposes a concept of user training, which have proven their effectiveness for many years.

Program Versions, Network License

SINETZ is available as a single user license and also as network license.

The single user license allows to install the program on a PC-system of the licensee.
The network license enables the access to the program system by any PC in the network, limited by the number of users. This depends on the acquirement of a network license for one or more users.

Maintenance and update service, Hotline

The SINETZ maintenance agreement includes the user support, software development and error releases.A built-in update function opens the access to
A detailed documentation describes the functions of SINETZ and additional programs. Beyond the printed and online program documentation the user is supported by competent personal of the SINETZ hotline. In many cases project-related various solution trials can be shown. The direct and fast contact to the SINETZ hotline by telephone and e-mail ensures to put the users interest on the processing of his project in the foreground. Effective use is guaranteed by SINETZ with that.
