ABZ
recently received a recommendation from a new DFS customer.
Quotes from his letter are provided below:
"I
have been using PIPE-FLO® for 10 years and am switching
to DesigNet for the following reasons."
Cost
“My
personal opinion as a professional engineer is that, for the
money, I get way more bells and whistles in a very user friendly
package with ABZ Inc's DesigNet versus any version of PIPE-FLO®
or AFT Fathom and the cost is much less.”
“Comparing
apples to apples, PIPE-FLO® costs significantly more (three
times as much) than Design Net without getting compressible
flow capabilities. PIPE-FLO® has developed a "lite"
version to keep the costs down but it only handles about 25
pipelines.”
DesigNet
provides both compressible and incompressible flow calculation
in one easy to use package at a cost of less than 15% of PIPE-FLOW®
(when comparing the $825 cost of DesigNet versus the almost
$6,000 cost of PIPE-FLOW® Professional and PIPE-FLOW®
Compressible together. This cost difference is even more dramatic
for multi-user copies).
Ease
of Use
“To
do compressible flow calculations with PIPE-FLO® Professional,
I have to break down the piping system in many small pieces
to fall within the parameters in Crane Technical Paper 410 regarding
restrictions to observe in applying the Darcy formula. This
requires significantly more labor to add more nodes and pipelines.”
“To
use a program that only does incompressible problems, the user
must manipulate the input such that the compressibility of the
fluid can be ignored during the solution. This is very time
consuming and error prone. With DesigNet, there is no need to
manipulate the input data to solve a compressible problem.”
“To
perform a PIPE-FLO® calculation, two files have to be created,
the final file being the pipeline line up. This is labor intensive
and sets you up for mistakes.”
“When
performing single line incompressible liquid flow calculations,
even the old ABZ Crane Companion DOS Version blows away PIPE-FLO®
in speed and simplicity. New runs requiring changes in fluid
properties can be made in a fraction of the time using the (ABZ)
Crane Companion versus PIPE-FLO®.”
With
DesigNet, the user specifies the actual or planned piping system
without regard to any program limits or special actions based
on fluid type. The user simply lays out the system, defines
the fluid, specifies what is known and DesigNet does the rest.
Program
Output Quality
“Nearly
every person I've talked to who's used PIPE-FLO® or reviewed
the results, says that the output results are extremely confusing
and very hard to understand. I almost always have to sit down
with my clients and "teach" them how to decipher the
output.”
“Fonts
on flow sheet graphics labels are too small and have been that
way for 10 years. Clients have complained on just about every
set of calculations I've reviewed with them that they have a
hard time seeing the results on the pipeline graphics.”
DesigNet’s user interface and output reports were designed
by engineers for engineers. DesigNet customer have consistently
remarked how much their clients have appreciated the program
outputs. ABZ has listened to our customers and incorporated
user comments with each version of DesigNet.
“One
of the biggest problems with PIPE-FLO® for the past 10 years
is the failure for PIPE-FLO® developers to provide for one
to see intermediate pressures at any point in the system without
having to spend extra time adding more nodes and pipelines.”
With DesigNet, the user only needs to click on a branch in the
network to see intermediate pressures and flows. In addition,
printouts can be generated that provide the same information
and more.
What
DesigNet Competitors Say
“When
evaluating PIPE-FLO® versus DesignNet, I asked the developers
of disadvantages of their competitors. The only negative I got
from PIPE-FLO® sales people was that DesigNet may take extra
minutes to run complicated pipeline systems versus PIPE-FLO®.
i.e., the actual calculation engine is supposed to be much faster
than DesignNet. The occurrence of a calculation requiring that
type of intense model is so rare with most engineering consulting
companies or major owner/operators that I'll put up with the
extra run time to get the many extra features at such a good
value.”
Competing
programs may make underlying simplifications when solving a
problem with the goal of achieving faster results. DesigNet
does not. ABZ has dramatically increased the speed of DesigNet
in the upcoming version 4 by being more creative in programing
rather than oversimplifying the calculation methods.
