System 1738 Installation Methods12
a) The PVC materials used in System 1738 piping are
strong and lightweight materials. Care shall be
taken in handling and storage to prevent damage
to the pipe.
System 1738 pipe shall be given adequate support
at all times. It should not be stacked in large piles,
especially in warm temperature conditions, as
bottom pipe may become distorted and joining will
become difficult.
For long-term storage, pipe racks shall be used,
providing continuous support along the length. If
this is not possible, timber supports of at least 3
inch bearing width, at spacings not greater than 3
foot centers, shall be placed beneath the piping. If
the stacks are rectangular, twice the spacing at the
sides is required. Pipe shall not be stored more than
seven layers high in racks. If different classes of pipe
are kept in the same rack, pipe with the thickest
walls shall always be at the bottom. There shall be
NO sharp corners on metal racks.
For temporary storage in the field when racks are
not provided, care should be taken that the ground
is level and free of sharp objects (i.e. loose stones,
etc.). Pipe shall be stacked to reduce movement,
but shall not exceed three to four layers high.
Since the soundness of any joint depends on the
condition of the pipe end, care should be taken in
transit, handling and storage to avoid damage to
these ends. Care should be taken when unloading
and handling pipe in cold weather. Dropping pipe
from a truck or forklift may cause damage. Methods
and techniques normally used in warm weather may
not be acceptable at the lower temperature range.
When loading pipe onto vehicles, care shall be
taken to avoid contact with any sharp corners (i.e.
angle irons, nail heads, etc.), as the pipe may be
damaged.
While in transit, pipe shall be well secured and
supported over the entire length and should never
project unsecured from the back of a trailer.
(b) Prolonged Outdoor Exposure
Prolonged exposure of System 1738 pipe to the direct
rays of the sun will not damage the pipe. However,
some mild discoloration may take place on the
exposed surfaces.
(c) Protection – Covering
System 1738 PVC pipes are packaged in crates and
wrapped in protective plastic film, which protects
from UV and keeps the pipe clean. Discoloration of
exposed pipe can be avoided by shading it from
the direct rays of the sun. This can be accomplished
by covering the stockpile or the crated pipe with
a light colored opaque material such as canvas. If
the pipe is covered, always allow for the circulation
of air through the pipe to avoid heat buildup in
hot summer weather. Make sure that the pipe is
not stored close to sources of heat such as boilers,
steam lines, engine exhaust outlets, etc.
(d) If painted, only latex/waterbase paint shall be used
and all product markings must be either visible or
accessible for visual inspection.
NOTE: Apply masking tape over product markings
prior to painting. The ability to pull-back on the
masking tape will allow for future inspection.
Handling and Storage of System
1738 Cement and Primer
Store System 1738 cement and primer in the shade
between 40
o
F (4
o
C) and 110
o
F (43
o
C) or as specified on
label. Keep away from heat, spark, open flame and other
sources of ignition such as electronic vapor cigarettes.
Secure container lid tightly when not in use to prevent
escape of solvent vapors. If the unopened container is
subjected to freezing, it may become extremely thick or
gelled. This cement can be placed in a warm area, where
after a period of time, it will return to its original, usable
condition. However, it will not be the case if gelatin has
taken place because of actual solvent loss - for example,
if the container was left open too long during use or not
properly sealed after use. Cement in this condition should
not be used and should be properly disposed of per
Local Jurisdiction requirements.
IPEX solvent cements are formulated to be used “as
received” in original containers. Adding thinners or primers
to change viscosity is strictly prohibited. If the cement is
found to be jelly-like and not free flowing, it should not
be used.
The impact resistance and flexibility of System 1738
piping are reduced as temperatures approach 32
o
F
(0
o
C) and below.
