Thang Long Flexible Pipes, due to their spiral corrugation, offer
a wide range of advantages
THANG LONG FLEXIBLE PIPES OFFER BEST
SOLUTIONS FOR CABLE PROTECTION
HDPE Flexible Pipes feature high efficiency in protecting power cables and
communication cables. This product was invented in the 1960s in Japan, and
since has found wide application in Japan, Korea, Thailand, Malaysia, China,
South Africa, Arabia Saudi, etc., replacing PVC or steel straight pipes
in installations of power and communication cables. In 1968, flexible pipe
products won an award of the US Wire Association and the 11th Ichimura
Prize (Japan).
In 1998, for the first time in Vietnam, Thang Long HDPE Flexible
Pipes were manufactured on a production line of Korean technology,
meeting KSC 8455 Korean Standard, for underground applications in
conformity with TCVN 7997-2009 and Japanese Industrial Standard
JIS C 3653-1994.

When TFP, both ends of which have been specially processed
with terminals, is stretched axially, it displays tensile strengths for
different sizes, as shown in the top figure. When released from an
approximately 40% elongation, TFP returns to its original state without
retaining any permanent strain. In addition, its joints demonstrate

It is recommanded to use pipes of smaller sizes: Þ32/25, Þ40/30,
Þ50/40, Þ65/50, Þ85/65, Þ105/80. Pipes of larger diameters
should be restricted. Large pipes would affect the natural scenery.
2. Color
Grey TFP are recommended for surface installations. During grey TFP
production, UV-resistant antiaging agent is added to the material.
Color durability of grey TFP is also improved. Grey color also
harmonizes better with the electric equipment surrounding.
Pipes of other colors, e.g. orange ones, are not recommended
because they do not contain antiaging agents and do not match the
surrounding.
3. Fittings

Cable installations on bridges or embedded in concrete
with a space limited by its structure
1. Size of pipe
Note: The pipe inner diameter shall be at least 1.5 time the overall
diameter of the power cable accomodated. In order to avoid bad
effect on bridge concrete construction, it is important to consider the
outside diameter of pipes to be installed.
For instance, instead of straight Þ48 PVC pipes, TFP Þ50/40 can be
used, without causing difficulty to pulling cable in or impairing heat
dissipation from cables.
Due to their corrugated configuration, TFP also present some other
advantages: higher adherence to concrete
TFP up to 200m long are available (on order), minimizing the number
of joints to be made in concrete. TFP joints are sturdy and water-tight.
TFP endure well concrete compacting and hard impacts, excluding
risk of ingression of water and other foreign matters.
Available pilot wire makes it easy to pull in cables. Low
friction reduces risk of cable straining.
2. Color
Orange TFP should be used.
3. Fittings
1. Sealing tape, Vulco tape, PVC tape
2. Joint sleeve or Connector

Daây moài/Pilot wires
Pilot wires are not intended for pulling power cables.
For TFP of a diameter up to 80 mm, a steel wire 1.6
mm covered with a plastic layer at least 0.2 mm thick
is provied inside. For TFP of a diameter of 100 mm and
larger, a steel wire of 20 mm covered with a 0.3 mm
plastic layer is provided inside.
Some notes on pilot wires readily provided in TFP:
1. Use the provided pilot wire only for pulling in power cables of an
outer diameter up to 20 mm.
2. If the outer diameter of the power cable is larger than 20 mm, but
smaller than 50 mm, use a nylon cord with a diameter of 6 mm or larger,
instead of the provided pilot wire, to pull the power cable in.
3. In case the outer diameter of the power cable is larger than 50
mm, please use a PVC-covered fine steel cable of a diameter of
Þ3 mm to Þ16 mm, depending on the weight of the power cable
to be accomodated.
4. For underground 110 kV or 220 kV installations, please contact BaAn
and order PVC-covered fine steel cables to be used as pilot wires.

Application procedure
Insert waterproof cap (3)(refer to Waterproof cap, "Fittings and
Materials") into the end of TFP and cover it with waterproof compound
(4) or sealing tape. Wrap vul-co tape around it and secure its end
with PVC tape. The end of the waterproof cap should be cut
beforehand to get a hole which matches the outer diameter of the
cable. If TFP is fixed to a manhole, its protruding length should
match that required for taping it before fixing it to the manhole.

For warning there is a power line below. This 30cm
wide tape is made of PP (polypropylene) cloth, then
folded and simply stuck to make folds every 5cm along
its length (see the picture). Thanks to these folds, when
laid in cable trenches and then covered with soil, the
tape would not break under the soil load or later, under
outer forces, because these folds can be easily

TFP, if used as a power cable duct, shall be laid in accordance
with the requirements prescribed in the Code for Electric
Installation and in other applicable regulations. At construction
sites, therefore, TFP should be laid in accordance with the stan-
dardized laying procedures described below.
Trenching
The trench cross section is determined by the number of conduits to be
laid. This cross section should be determined with considerations of
economy and safety associated with the laying operation. It is necessary
to follow all safety procedures so that landslides do not occur at the min-
imum cross section.
The lowermost TFP shall not be laid directly on rocks or pebbles. The trench
bottom shall be leveled and then covered with sand before laying TFP.

TFP arrangement and sand filling
When two or more TFP conduits are to be laid in parallel in the
same trench, they should be arranged with the specified distances
as shown in Fig A. To this end, a simple gauge shown in Fig B should
be prepared to straighten the laid TFP every three or four meters.
The straightened TFP should be then held in place with sand or
equivalent means, and the gauge should be removed.
Passing test rod
When laid completely, TFP should be checked for straightness and
internal void. Test rods should be selected according to the size of
TFP. Passing of test rods is recommended in provisional burying and
when TFP systems are laid completely.
Filling
After conduits are checked for void by passing a test rod through
them, fill in the trench to complete the laying.
Cable pulling-in
Cables should be then pulled into TFP by using the pilot wire
previously accomodated in the TFP. The pilot wire should be used
only to draw cable-pulling wires through TFP conduits.
When concrete buffers are used
When buffers are used in TFP arranging, installation should be carried
on with the following steps:
1. Place buffers in line along the trench, at specified distances.
2. Lay TFP on the whole tract. The TFP may not be properly arranged
at first and need further alignment.
3. Secure conduits on the whole tract to buffers using nylon cord.
4. Composite connectors shall be used for joining TFP accomodating
110 kV or 220 kV power cables. For medium and low voltage cables or
telecommunication cables, plastic connectors or joint sleeves should be used.
TFP joining work shall be carried on under supervision of site technicians.
5. Proceed to final alignment.
6. Check the conduits for straightness and void, using a test rod.
7. Fill back the trench when all the above steps are completed.
- Filling with sand: Sand is poured gradually, filling the trench from
its bottom to higher layers.
- Filling with concrete: In mechanized concrete pouring, the filling should be
made in two steps. First, concrete is poured up to half the height
of the conduits. The second concrete pouring is made 3 - 5 hours later,
when the last concrete has hardened, up to the specified level. Manual
concrete pouring is used when work volume is small. The concrete filling
may be made continuously, in one step.

Notes on conduit installations on bridges
- Arrange TFP conduits well aligned, close to metallic structures of the
bridge.
- Secure tightly TFP conduits to metallic structures using wires so
that they will not be displaced during concrete pouring.
- Seal TFP joints carefully using vul-co tapes to prevent water and
concrete from entering conduits.
- Special supervision is needed:
+ During TFP laying: TFP shall be moved away from locations where
welding work is taking place to avoid possible damage caused by
hot welding scales.
+ During concrete compacting: When using vibrators, avoid poking
them on TFP, which would break TFP-securing ties or pierce TFP.
- TFP ends embedded in handholes should be provided with
bellmouths to prevent cables from being scratched and damaged
during pulling them through the TFP. Because of the fact that a large
number of handholes are included in lighting systems on bridges,
this requirement is strongly recommended.
- Bridge constructions include expansion joints to account for thermal
expansion and vibration, which can reach 65mm. Hyundai pipes
should be used as conduits crossing these joints. BaAn has the
exclsive right to supply Hyundai pipes in Vietnam. For details, see
brochure Hyundai Conduit.

Cable installations on bridges or embedded in concrete with a space limited by its structure 1. Size of pipe Note: The pipe inner diameter shall be at least 1.5 time the overall diameter of the power cable accomodated. In order to avoid bad effect on bridge concrete construction, it is important to consider the outside diameter of pipes to be installed. For instance, instead of straight Þ48 PVC pipes, TFP Þ50/40 can be used, without causing difficulty to pulling cable in or impairing heat dissipation from cables. Due to their corrugated configuration, TFP also present some other advantages: higher adherence to concrete TFP up to 200m long are available (on order), minimizing the number of joints to be made in concrete. TFP joints are sturdy and water-tight. TFP endure well concrete compacting and hard impacts, excluding risk of ingression of water and other foreign matters. Available pilot wire makes it easy to pull in cables. Low friction reduces risk of cable straining. 2. Color Orange TFP should be used. 3. Fittings 1. Sealing tape, Vulco tape, PVC tape 2.

Implementation procedures and TFP-joining methods proposed by BaAn are simple, cost saving, safe and effective. Please refer to "Instructions for installation" for implementation procedures of 110 - 220 kV underground installations. TFP for 110 - 220 kV installations feature some additional performance: Coils of TFP Þ230/175 and Þ260/200 are manufactured with a length up to 100 m, reducing the pipe joints to be made. Two PVC-covered galvanized steel Þ3.2 mm pilot wires, of a 10 years' durability in natural climatic conditions, are readily supplied. 1. Size of pipe TFP Þ230/175 or TFP Þ260/200 are used. 2.

TFP, if used as a power cable duct, shall be laid in accordance with the requirements prescribed in the Code for Electric Installation and in other applicable regulations. At construction sites, therefore, TFP should be laid in accordance with the stan- dardized laying procedures described below. Trenching The trench cross section is determined by the number of conduits to be laid. This cross section should be determined with considerations of economy and safety associated with the laying operation. It is necessary to follow all safety procedures so that landslides do not occur at the min- imum cross section. The lowermost TFP shall not be laid directly on rocks or pebbles.

  • 47. TFP arrangement and sand filling When two or more TFP conduits are to be laid in parallel in the same trench, they should be arranged with the specified distances as shown in Fig A. To this end, a simple gauge shown in Fig B should be prepared to straighten the laid TFP every three or four meters. The straightened TFP should be then held in place with sand or equivalent means, and the gauge should be removed. Passing test rod When laid completely, TFP should be checked for straightness and internal void. Test rods should be selected according to the size of TFP. Passing of test rods is recommended in provisional burying and when TFP systems are laid completely. Filling After conduits are checked for void by passing a test rod through them, fill in the trench to complete the laying. Cable pulling-in Cables should be then pulled into TFP by using the pilot wire previously accomodated in the TFP. The pilot wire should be used only to draw cable-pulling wires through TFP conduits. When concrete buffers are used When buffers are used in TFP arranging, installation should be carried on with the following steps: 1. Place buffers in line along the trench, at specified distances. 2. Lay TFP on the whole tract. The TFP may not be properly arranged at first and need further alignment. 3. Secure conduits on the whole tract to buffers using nylon cord. 4. Composite connectors shall be used for joining TFP accomodating 110 kV or 220 kV power cables. For medium and low voltage cables or telecommunication cables, plastic connectors or joint sleeves should be used. TFP joining work shall be carried on under supervision of site technicians. 5. Proceed to final alignment. 6. Check the conduits for straightness and void, using a test rod. 7. Fill back the trench when all the above steps are completed. - Filling with sand: Sand is poured gradually, filling the trench from its bottom to higher layers. - Filling with concrete: In mechanized concrete pouring, the filling should be made in two steps. First, concrete is poured up to half the height of the conduits. The second concrete pouring is made 3 - 5 hours later, when the last concrete has hardened, up to the specified level. Manual concrete pouring is used when work volume is small. The concrete filling may be made continuously, in one step.

Notes on conduit installations on bridges - Arrange TFP conduits well aligned, close to metallic structures of the bridge. - Secure tightly TFP conduits to metallic structures using wires so that they will not be displaced during concrete pouring. - Seal TFP joints carefully using vul-co tapes to prevent water and concrete from entering conduits. - Special supervision is needed: + During TFP laying: TFP shall be moved away from locations where welding work is taking place to avoid possible damage caused by hot welding scales. + During concrete compacting: When using vibrators, avoid poking them on TFP, which would break TFP-securing ties or pierce TFP. - TFP ends embedded in handholes should be provided with bellmouths to prevent cables from being scratched and damaged during pulling them through the TFP. Because of the fact that a large number of handholes are included in lighting systems on bridges, this requirement is strongly recommended. - Bridge constructions include expansion joints to account for thermal expansion and vibration, which can reach 65mm. Hyundai pipes should be used as conduits crossing these joints. BaAn has the exclsive right to supply Hyundai pipes in Vietnam.
