The siphonic system can use 100% of the selected pipe size,
which again affects the required pipe sizes needed. Valsir only
has one model of siphonic system that can be used in various
applications. Further, he discussed the need for design and 3D
modelling systems as a call to industry requirements, and correct
flow rate calculations through such software and integration with
other software programs. Also, the correct process of installing
products, the correct number of brackets and where they should
be spaced, as an example, so that when on site, the plumber will
have all the requirements exactly set out.
Casper Maree, technical manager of Valsir-Uneeq SA, spoke on
the engineering perspective of the Ventilation Branch Fitting (VBF)
products and single-stack designs, which are capable of removing
double-stack installations. The capability of this includes handling
multiple systems connected to the one stack, which is a large cost
saving for any project. Continuing through the Valsir products, the
Blackfire product range is a newcomer and was officially launched
at ISH 2019 in Frankfurt, Germany.

Attendees were demonstrated to the quality and testing of the
Valsir product range, followed by a question and answer session
fielded by the team. In closing, winners to the evening draw were
selected and presented with their prizes, followed by a networking
opportunity and some eats.
BLACKFIRE LAUNCH AT ISH 2019
Speaking to Gruppi in Frankfurt at the ISH show, the Blackfire range
is a three-layer polypropylene range, ranging between 32mm and
160mm. It is a push-fit system, which means that there is no need
for any welding or welding machines on site. “The pipe is black
because it contains carbon black, which is a UV stabiliser. This
means this range can also be used outside when exposed to UV
rays,” Gruppi said.
The system comes complete as the entire range with all the fittings.
The system is also designed to be used with a singe stack for high-
rise buildings, making this product the fifth major in the Valsir range,
along with Triplus, Selera, PP3, and HDPE.

Blackfire is different from the other brands for two reasons: the first
is that it is a B1 fire-rated pipe, meaning that within 20 seconds, it
will stop burning; and secondly, and importantly, it is the first three-
layer pipe to be developed with this certification.
The pipe is black on the outside but white on its inside, as the
white colour makes video inspection much easier. The pipe was
designed specifically for high-rise buildings as a mechanism to
stop fires spreading to other floors. It also couples with a fire-
stop collar. So, when there is a fire, after a certain time, the pipe
will melt and the collar will close, stopping the path of the fire
through the pipe system. This system is essentially for markets
where fire safety is very sensitive and also for general safety in
multistorey buildings.
“At Valsir, we give a lot of opportunities to our customers, the
consultants, and the engineers to select what is most suited
for their application, because not all applications are the same.
What is great about our products is that each range can be used
with another, essentially being able to mix the systems. You can
custom-fit your solution with exactly what you need in an efficient
way,” Gruppi concluded on the ISH stand. PA
