About MICRO TECHNO

MICRO TECHNO, since its establishment in 1993, was a target company in Italy for the Chemical, Petrochemical, Pharmaceutical Industry.

Over 25 years of experience in the field of the engineering software allowed us to select some of the most qualified softwares for plant engineering and to propose them to the Italian market, including a complete pre and post-sale support.

In addition to the above, MICRO TECHNO develops and distributes worldwide MT-MECH, a complete software package series for mechanical design of Pressure Vessels and Shell&Tubes Heat Exchangers.

MT-COMP : Components Mechanical Design.

MT-VESS: Pressure Vessels (Horizontal/Vertical) Mechanical Design.

Nozzles The function of the wall data import on the nozzles modulus of the program has been fixed. The joint efficiency was not correctly imported for different system units.

3.

Materials A control has been added to the calculation of the Young modulus. When the design temperature is greater than the maximum tabulated a warning message is issued and the program stops..

4.

Materials The calculation of the allowable stress of austenitic stainless steels per EN 13445 has been fixed. For steels with elongation less than 30% the calculation of the allowable stress was wrong.

5.

Materials The tolerance of materials per EN 13445 has been added to the program.

6.

Girth Flanges The calculation of girth flanges with ring joint gasket has been added to the program

7.

Tubesheets The option for the calculation of the MAWP on the tubesheet modulus has been added to the program. This allows to avoid the MAWP calculation, that can be very time consuming, when trying alternative calculations before the final tubesheet configuration.

8.

Saddles The saddle standard and the saddle calculation has been revised. The saddle top flange is now always considered and the transition plate is taken into consideration only when required by the Zick analysis. The saddle stress analysis according to the MOSS is based now on the saddle top flange.

9.

Engineering Data The archive of the engineering data has been revised with the addition of the caps. At the moment, only caps per ANSI B16.9 are loaded in the archive.
