1.
Insulation over pipes to be fitted :- Around 80% of piping
up to 160 mm diameter used in buildings can be insulated with
tube sections before fitting. This simplifies the task and
saves time, taking advantage of the wide range of applications
offered by an elastomeric product like KAIFLEX.
Slide the KAIFLEX tube directly over the pipe from one end.
Do
not force the tube while fitting as this will deform the material. Instead push
it smoothly without making unnecessary pressure. This will ensure that it grips
to the surface of the pipe naturally especially around the all important curved
sections.
When a section ot tubing has been positioned satisfactorily,
fix at least one end with KAIFLEX glue to the pipe.
Apply
glue to the edges of the tubing already in place and the edge
of the next section of tubing to be positioned.When adhesive
is dry but tacky, bring the edges of the tubing to be glued
together and press tightly.
Aluminium self adhesive tape or Kaiflex self adhesive tape
should also be used over Joint for better results.
If
the underlying pipe has to be brazed, free an area 25/30 cm
long between the part of the tubing .Once the pipes have cooled,
the insulation can be completed.

Insulation over fitted pipes :- If
the piping has already been installed, the KAIFLEX tubing
must be cut along its length to fit in. Use only the sharpest
knife to effect the cut-this makes the subsequent glueing
far easier.
We
recommend using the KAIFLEX cutter which is ideal for longitudinal cuts. Position
the tube to so that the edges are separated, and apply an even layer of KAIFLEX
glue Once
the glue has dried, reseal the tube, pressing the edges firmly together When
making a joint between two lengths of tubing, cut the insert a little longer than
necessary. (Acoupleof millimetres) If the insert is not long enough, the insulating
properties in that area will be reduced. Cut
the insert along its length and glue into place.Aluminium self adhesive tape should
also be used
over Joint for better results. |  |

3. Insulation over fittings :- KAIFLEX
tubing can be easily cut and fabricated into fittings for either welded or threaded
joints like bends, T,s and elbows, on both new and existign lines. For Screwed
fittings, sleeved fittings cover should be fabricated form tubing of same wall
thickness as used on the pipe. The inner diameter of the fittings must be large
enough to overlap the insulation on the stright pipe. Fabricate fittings by using
45 O & 90 O angles cut and join with adhesive. When adhesive has dried, slit
the fitting through the centre. | |

Insulation over valves:-These
can be insulated in a number of ways, depending on the type of stopcock.
(I)
Small Valve Stem
From the edge of the KAIFLEX, make a cut long enough to
house the stopcock and punch a hole to fit the stem. Fit
the tube snuggly around the stopcock and glue the edges t ogehter, then attach
it to the adjacent tube. (II)
Large diameter valve stem
Insulate the pipe right up to the stopcock on
both sides. Wrap KAIFLEX self - adhesive insulating tape around the base of the
stopcock.Cut a section of KAIFLEX tubing as long as the circumfrence of the tubing
already in place and cut it along its length. Flatten the tube out and make a
longitudinal cut with a hole punched at its end to take the stopcock housing.
Position this around the stopcock so that the sleeve overlaps the ends of the
two underlying tubes. If necessary, remove the stopcock if this gets in the way.
Glue and stick
the sleeve’s edges. If necessary the stem of the stopcock can also be insulated
by applying a ring shaped section from one of the off-cuts. |  |

Insulation Supports
:- In order to guarantee a constant insulation especially when suspension
device
are in use KAIMANN suggests the use of a special support device. A large number
of diameters are available to allow easy and efficient insulation. |  |
| 6.
Insulating piping over 160mm with sheets :- Wrap
a strip of KAIFLEX, using the thickness you want, round the pipe to measure the
exact length required.
Mark out the length required on a KAIFLEX Sheet.
Cut
carefully along the line.To ensure accurate results, use a metal ruler.
Apply
an even layer of KAIFLEX glue along eachedge and allow to dry.
Wrap
the insulation sheet around the pipe and press the glued edges together starting
at the ends, then the centre and then working along the rest of the length.
Glue
the insulating sheeting to the subsequent sections along the length of the pipe.
If the tubing thus created is not correctly lined up, push one against the other
slipping the brush in the gap and twist until they are aligned. |  |
| 7.
Insulating over tanks :- There
are two possibilities to insulate the tank. Either insulate the domed surface
and the subsoil or the walls. We will show the second possibility exemplary. Before
insulating, clean the whole surface carefully with KAIFLEX thinner.
First
of all, lage the tank walls. Use the same method as with piping. Measure the circumference
of the tank with a strip of KAIFLEX, and measure the height. Mark
the dimensions out on a sheet of KAIFLEX K 414 glue over the entire surface of
the sheeting with a flexible spatula and , with a brush, over the walls of the
tank. Glue the edges of the sheet, then stick the insulation to the tank, joining
the edges together.
To Insulate the domed surface, first measure its overall
diameter with astrip of the same KAIFLEX. |  |
| 8.
Insulation over ducting :- Measure
the size of the duct & determine the size the insulation material sheet required
for insulation. Cut the material to the measured size with a sharp knife &
straight
edge. Ensure that the cuts are as accurate as possible and with smooth edges to
ensure full contact with mating sheets when bonded together. Do not stretch sheets
and always apply smooth skin surface facing out. The surface of duct to be insulated
should be throughly clean, dry, oil free, and unheated to ensure proper adhesion.
By
using a sharp knife cut KAIFLEX sheet accurately and neatly.
Place
sheet in desired position before adhesive makes initial contact as repositioning
after contact is difficult.
Join
seams after insulation is in place by separating the cut edges & brushing
a thin coat of adhesive on both surfaces
Seams
of ducting can be insulate with strips of KAIFLEX sheet.
Finished
ducting insulation looks neat and clean.

Self Adhesive pre - cut tubes and Self Adhesive Sheets are also available for
quick & simple installation. |  |

Weather & UV rays protection for out door insulation :- We recommend painting
insulation outdoors with KAIFINISH to protect it from the weather and from UV
rays. To complete the protection, apply two layers of top coat. An extra layer
of paint should be applied every two years. Alternatively self adhesive aluminium
foil or sheet can be used to cover the out door insulation. |  |
