Materials
The pipes are made of high density polyethylene (PE-HD), which has very good mechanical and chemical properties, is an extremely environmentally friendly material and is practically irreplaceable in the current time of constant search for economical and long-lasting solutions in the field of cable protection.
UV stabilizers are added to the polyethylene, which enables greater resistance to weathering and slows down aging.
The pipes are made of PE-HD raw material with the following characteristics:
| density | > 0,947 | g/cm³ |
|---|---|---|
| melt index MFI 190/5 | 0,4 - 1,3 | g/10min |
| modulus of elasticity | ≥ 800 | N/mm² |
Coiled tubes have a low density polyethylene (PE-LD) inner tube wall with the following characteristics to achieve greater flexibility:
| density | 0,92 | g/cm³ |
|---|---|---|
| melt index MFI 190/5 | 0,25 - 0,9 | g/10min |
| modulus of elasticity | ≥ 200 | N/mm² |
STIGMAFLEX® TK pipes made of PE-HD for protection of telecommunication cables
Pipes are manufactured in accordance with STS-06/047 and meet the requirements of applicable regulations and standards currently in force in the territory of the Republic of Slovenia, as well as meet the requirements for the use of telecommunications equipment and materials in the Telekom Slovenije network.
The standard color for the outer profiled wall of the pipe in coils is yellow, and black for pipes in 6m bars. Due to technical regulations, yellow marking lines on the perimeter of the pipe are used to mark the purpose. The marking lines are made by the coextrusion process, so the marking remains permanent. For the needs of Telekom Slovenije, the tube or marking line on the tube is orange. Other colors are not excluded from the production program and depend on the customer’s wishes and quantity.
STIGMAFLEX® EL pipes made of PE-HD for protection of power cables
Pipes are manufactured in accordance with STS-06/048 and meet the requirements of applicable regulations and standards currently in force in the territory of the Republic of Slovenia. The standard color for the exterior profiled wall of pipes in coils and bars is red. For greater protection against the effects of UV rays, we also produce black pipes, which are more durable than pipes of other colors. To properly mark black pipes, we use colored marking lines that are on the perimeter of the pipe. The marking lines are made by the coextrusion process, so the marking remains permanent. Other colors are not excluded from the production program and depend on the customer’s wishes and quantity.
