Engineering | Meca Enterprises Inc


Meca Enterprises specializes in the design of stacks, but we also design other types of process equipment. Thanks to today’s technology, most of our communication and design can be done completely via phone and email. We send all designs electronically in a PDF file, which allows immediate transfer of information.

Self Supported Steel Stacks
Meca has designed many different types of self supported stacks, ranging in height from 6 m (20ft) to 100 m (328 ft.). Some special design considerations have included:

  • Single Piece Lift of Stack
  • Special Breech Openings
  • Low Temperature


  • “Piggy Back” Stacks
  • Vibration Design
  • Retrofit of Existing Stacks

Guy Wire Supported Stacks
There are very few companies that perform the design of guy wire supported stacks. Meca has designed many guy supported stacks ranging from 15 m (50 ft.) to 167 m (550 ft.) in height. We can save you considerable time and money due to our experience in the area of guyed stack design. We have performed the following types of special designs:

  • Single Piece Lift of Stack (sometimes done from multiple lift points)
  • Low Temperature Design (Ambient and Cryogenic)
  • Piggy Back Design of one stack off another
  • Unique Guy Arrangements
  • Tandem Stacks

Derrick Supported Stacks
Extensive experience designing derrick supported stacks:

  • 3 Sided or 4 Sided
  • Pipe Members
  • Flat Faced
  • Demountable

Finite Element Analysis
Finite element analysis does not always have to be expensive. We encounter certain types of problems repeatedely involving stacks, piping, and pressure vessels. Therefore, we have become very adept at building certain geometries very quickly to provide a cost effective solution.

Air Cooled Exchangers
Meca verifies the structural integrity for air cooled exchangers for various types of coolers, and can evaluate box headers.
