Engineering & Design

Since 1980 CALTUCA has proven experience in design, manufacture and servicing of heat transfer equipment for the Oil, Chemical, Petrochemical, Gas and Electric Utility Industries. CALTUCA’s Design personnel is trained to perform the best thermal and mechanical design of this kind of equipment complying client’s requirements and specifications as well as standars and codes to obtain an economical and smallest solution. In accordance with our experience above will find the activities that our technical department can face in an A.C.H.E. Design.

a. Complete new thermal and mechanical design of an a.c.h.e. to comply with client’s requirements for process conditions, specifications,codes and standards.

b. Thermal simulation of an existing unit to meet new required process conditions.

c. Alternative’s evaluations to improve the equipment heat transfer.


Specialized Service

CALTUCA has specilized personnel for the design of A.C.H.E., usign the specific standards for this kind of equipments, such as ASME, API, ASTM, AWS, Etc., Also has specilized software for:

a. Basic Thermal rating design based on the HTRI xchanger suite or our in house developed program.

b. Detailed Mechanical Calculation, Based on ASME Section VIII Division 1, Wind and Seismic Calculation Based on UBC, ASCE, PDVSA JA-221 codes and standard. Those software were in house developed.

c. Detailed Enigineer automated Mechanical Pressure parts & General Arrengement Drawings. This software was in house developed.

d. Detailed Enigineer automated Mechanical Structural Parts and general Arrengent Drawings based on our standard design. This software was also in house developed.
