Thanglong HDPE Flexible Pipes (TFP) 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, Pakistan, 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, Thanglong HDPE Flexible Pipes were manufactured on a production line of morden technology, meeting KSC 8455 Korean Standard. Since 2009, Baan were manufactured for underground applications in conformity with TCVN 7997-2009.

Color:TFP have colors such as: orange, black, gray, blue, red, etc, including the three primany colors: Black TFP are used for underground. Orange TFP are used chiefly for underground installations. Gray TFP are used chiefly for surface installations.
TFP size and minium permitted bending radius
1. The inner diameter of TFP shall be at least 1.5 time the over-all diameter of the power cable accommodated.
2. For communication cables, the inner diameter of TFP shall be at least twice the overall diameter of the cables accomodated.
3. For minimum bending radius of TFP, please refer to Table 6.

Thanglong HDPE Flexible Pipes was used in distribution electrical substations, distributing frames at Hanoi, Gialai, Kontum, Daklak, Daknong, Lamdong provinces, etc.
1. Size of pipeFor better appearance, it is recommanded to use pipes of smaller sizes: 32/25, 40/30, 50/40, 65/50, 85/65, 105/80.Pipes of larger diameters should be restricted.
2. ColorGrey TFP and black TFP are recommended for surface installations. During black TFP and 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.

1. Size of pipeNote: 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 48 PVC pipes, TFP 50/40 can be used, without causing difficulty to pulling cable in or impairing heat dissipation from cables. Due to their corrugated configuration, TFP are much more rigid than straight pipes of the same thickness.TFP, with their corrugated shape, also present some other advantages: Higher adherence to concrete, easier in pulling cable in due to lower friction, minimal strain to cables.

Composite connectors are exclusively intended for joining TFP (this product was awarded with a Vietnamese efficient solution patent). Advantages: They provide watertight joints, easiness in joining TFP, no heating is needed. Test rods of recommanded size shall be used to check TFP conduits before pulling in cables. Bellmouths, waterproof caps are used as instructed. Two 3,2 mm pilot wire or 4 mm steel cable should be used to draw cable-pulling wires through TFP conduits.
Implementation procedures and TFP-joining methods proposed by Baan are simple, cost saving, safe and effective. Please refer also to book Constructions manualsTFP for 110 220 kV installations feature some additional performance: Coils of TFP 230/175 to TFP 260/200 are manufactured with a length up to 100 m, reducing the pipe joints to be made. Two PVC-covered galvanized steel 3.2 mm pilot wires of 10 years life in severe climatic conditions are readily supplied.

For warning there is a power line below, inclucling: BCB-1 warning tapes are imported from Korea, BCB-2 warning tapes (without folds) are made in Vietnam.
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 released, resulting in length extension.

Passing test rodWhen 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.
Steps of test rod passingAttach pilot wire (1) to the test rod (4) and wind the joint with PVC tape. Tie wire (5) to the other end of the test rod and wind the joint with PVC tape. Pull wire (1) to draw the rod into the TFP conduit.If the test rod passes through the conduit without trouble, the conduit is normal

When concrete buffers are usedWhen 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 ar ranged 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 accomo-dating 110 kV or 220 kV power cables. For medium and low volt-age cables or communication 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.
FillingAfter conduits are checked for void by passing a test rod through them, fill in the trench to complete the laying.

Cables pulling-inCables 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.

TrenchingThe trench cross section is determined by the number of conduits to be laid. This cross section should be with considerations of the most economy and safety associated with the laying operation. It is necessary to follow all safety procedures so that landslides do not occur at the minium 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

LayingTFP should be laid with care so as to prevent soil, sand and water from entering through their ends. The TFP delivered to the site are wound in cols, their laying shall be made in accordance with the following procedure. The TFP coil shall be unwound by rolling it along the trench, held by three or four wokers to avoid deforma-tion. If pulled along without being rolled, TFP will twist.

TFP arrangement and sand fillingWhen 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.
