Technical Specifications

Technical note: Wall thickness, dimensional tolerances, coil or straight-length options, weight, bending radius, temperature range, mechanical properties, and applicable manufacturing standards should be confirmed against the manufacturer’s current technical datasheet before specification or procurement.

Understanding the 110/100 mm Configuration

The designation of 110/100mm reveals its name, which refers to the standard outer and inner dimensions of the duct. The 110mm outer diameter indicates the size of the duct externally, while the 100mm inner diameter refers to the standard inner flow within the duct for installation of cables.

This design gives a large crossing path for applications that need a large duct rather than a small one. The final load of the cable, pulling methods during installation, and other specifications should be analyzed according to project requirements.

PE100 HDPE Construction

The STC HDPE PE100 Duct 110/100mm 4 Orange Strips uses PE100-grade HDPE as specified in the product name. PE100 is the material grade identified for the duct and forms an important part of its technical specification.

For project procurement, the PE100 designation should be considered together with the specified SDR, dimensional requirements, applicable standards, and manufacturer documentation. Where additional material or performance requirements apply, they should be verified before installation.

Black Duct with 4 Orange Strips

The duct has a full-black base with four orange strips running along the duct. This combination provides a clear visual identification feature while maintaining the specified black duct configuration.

Color identification can be useful when multiple ducts or infrastructure pathways are installed within the same project. However, the exact meaning assigned to orange identification should follow the project’s approved drawings, specifications, duct-color schedule, and installation requirements.

SDR 17 and PN 10 Classification

The product is specified as SDR 17 PN 10.

SDR, or Standard Dimension Ratio, relates the nominal outside diameter of a pipe or duct to its specified wall dimension. PN 10 identifies the stated nominal pressure classification associated with the product specification.

For this duct, SDR 17 and PN 10 should be treated as part of the manufacturer’s stated product specification. Project engineers and procurement teams should verify the applicable standard and intended service requirements before final selection.

Advantages

Large 100 mm internal pipe

Internally the pipe has an inner diameter of 100 mm which provides a large internal pipe structure capable of supporting the installation of cables in comparison to smaller ducts.

The dimensions are clearly defined

The pipe’s dimensions of 110 mm outer diameter (OD) and 100 mm inner diameter (ID) are specified dimensions which lead to ease of selection of pipes and duct systems for projects.

PE100 material grade

The PE100 designation is a material grade specifications.

Presence of 4 orange stripes

Four orange strips provide easy visual recognition and enable duct identification in structured installations.

Design of a single main duct

Single main duct type gives the option of having a dedicated internal pipe route option.

The specification of SDR 17 and PN 10

The specification of SDR 17 and PN 10 gives the basis for detailed planning and possible selection of the pipes and their systems.

Applications

The STC HDPE PE100 duct 110/100mm 4 Orange Strips can be used in various applications like

Fiber Optic Infrastructure

Installation and Selection Considerations

Before installation, project teams should verify the duct dimensions, cable requirements, route conditions, installation method, and project-specific technical specifications.

Important considerations include:

• Confirm the actual cable or cable-bundle diameter against the 100 mm nominal internal pathway.
• Check required cable pulling tension and installation equipment.
• Follow the manufacturer’s recommended minimum bending radius.
• Verify jointing and connection requirements before installation.
• Maintain suitable duct alignment throughout the cable route.
