The Classic software allows to meet many calculation and cost evaluation needs for pressure vessels and heat exchangers. The following packages are available:
Software for mechanical design and checking of testing requirements for pressure parts and pressure vessels made of spheroidal graphite cast iron(SCGI) according to EN-13445 Part 6. In general the rules in the relevant parts of EN-13445 Parts 3 are applicable for spheroidal graphite cast iron, taking into account additions and limitations provided in EN-13445-6. For certain applications, ductile iron castings are proven to be a cost effective alternative with equal safety to steel castings, forgings and welded fabrications for pressure vessels. Castings can accommodate greater complexity of shapes and may unify different functions in the same part. FERRITIC DUCTILE IRON (Spheroidal Graphite Cast Iron) and AUSTENITIC DUCTILE IRON are included in the software.
Software for mechanical design of pressure vessels and heat exchangers in accordance with the Italian code VSR (integrated with the Recommendations by CTI – Comitato Termotecnico Italiano – for the use of the Raccolte ISPESL within the scope of the PED).
Software for mechanical design of steam generators in accordance with the Italian code VSG (integrated with the Recommendations by CTI – Comitato Termotecnico Italiano – for the use of the Raccolte ISPESL within the scope of the PED).
Software for mechanical design of simple pressure vessels according to EN 286 part 1. This is the harmonized standard for the Simple Pressure Vessel Directive (Directive 2009/105/EC):
The standard is used for the calculation of tanks containing air or nitrogen made either of Carbon Steel or of Aluminium Alloys. The software has a material data base and several component moduli for the calculation of cylindrical shells, domed and flat ends and flanges.
CARVES is a software for the calculation of stresses caused by nozzle loads and concentrated loads due to supports on cylindrical shells and spherical heads according to WRC Bulletins 107/297/537. See norms here. It can be used either as an integrated module in our classic edition calculation packages EN 13445, AD 2000 and VSR, or as a freestanding program. When used as a freestanding program, the software permits the use of different methods for the evaluation of the pressure stresses (not considered in the WRC Bulletins). The allowable stresses for the various stress categories (also not specified in the WRC bulletins) may be determined by the user.
COLOAS is a software for the calculation of towers under wind and earthquake loads according to the method of ASME Section VIII division 1. The software permits the design of columns considering all the possible load combinations for operating, exceptional and testing conditions, including the load combinations provided by the ASCE (=American Society of Civil Engineers) standards. It is based on the traditional design method contained in the book Process Equipment Design (Brownell-Young, 1959, John Wiley & sons), however the method has been interpreted so that a complete design procedure has been cabled into the software. The designer can start from the top of the column and determine the thickness of the different sections up to the supporting skirt, reducing them until he gets a warning message. In this way it is possible to reduce as much as possible the weight of the vessel, always remaining among the safety constraints imposed by the reference standards.
STEMEC is a software for complete mechanical design of shell and tube heat exchangers according to ASME VIII div. 1 and TEMA, including tubesheet calculation to UHX part, calculation of weights and evaluation of material costs based on the material prices stored in the data base. The software includes also an optional module allowing the calculation of workshop hours (or costs) by means of customizable tables providing times and prices for all the possible shop operations. Another option of the program allows the generation of drawings (setting plan, scantling drawing and tubesheet layout). An optional interface with the H.T.R.I. program Xist for thermal design of shell & tube heat exchangers permits to carry out complete mechanical design starting from the results of the thermal calculation.
PECOS is a software for cost evaluation of any type or shape of pressure vessels (towers, tanks, reactors etc.). The user has to input the geometric dimensions of all the vessel components. There is a material data base that may be implemented by the user with all the relevant material costs. The calculation of workshop hours (or costs) is based on customizable tables considering all possible shop operations. A new version with up-to-date user interface is planned for future release.
TRACCIA is a software for heat exchanger tubesheet layout with a CAD module for the modification of tubesheet layout by means of a graphic interactive optimized procedure. This software may be integrated into the STEMEC program in all cases where a tubesheet layout coming from the thermal design is not available. The software may also be personalized in order to supply the input media to be used for the drilling machine.
ZICK is a software for the calculation of horizontal vessels on saddle supports according to the method of Zick /PD5500, implemented for consideration of wind and seismic loads. The traditional Zick method has been used in many important design standards (ASME VIII division 2, PD 5500, CODAP, VSR, etc.).
