CLinT is a robust and user-friendly software for designing flexible liners in gravity flow pipes utilizing the MOP 145 method.  See available CLinT Calculators and how to order here.

Design of Circular and Non-Circular Shapes: CLinT  is capable of designing liners for a broad spectrum of sewer and culvert pipe configurations commonly found in today’s infrastructure, accommodating a wide variety of shapes, materials, and installation conditions.

Streamlined Geometry Input Parameters: Non-circular shape design involves numerous geometric parameters. CLinT requires only the minimum necessary input which defines the host pipe’s shape, and automatically calculates the rest of geometry elements. Similarly, CLinT/SL needs minimal input to define both the host pipe and slipliner geometry, streamlining the design process.

Integrated Identifying of Design Arcs: Both CLinT and CLinT/SL identify critical locations in the pipe profile where external loads exert the most significant effects, often found in the invert or on the sides of the pipe.

Host Pipe Material and Condition Considerations: The software adapts to the different behaviors of liners under loading, which depend on whether the host pipe is rigid or flexible. It also accounts for the pipe’s present condition, including ovality in circular pipe (4-hinge or elliptical) or deflection in non-circular pipe (hinge rotation angle), as well as local defects such as flattening or intrusion.

Cracking Modes: For cracked rigid pipes due to overloading, CLinT includes built-in cracking modes for various pipe shapes.

Gap Considerations: For CIPP liners, CLinT ensures that the gap between the liner and host pipe does not exceed 0.04 inches, as specified in MOP 145. It can also perform calculations with a fixed gap value exceeding this limit, which is useful for post-installation design reconciliation. For grouted slipliners, CLinT/SL assumes a zero gap.

Choice of Surface Live Loading : CLinT and CLinT/SL include various AASHTO and AREMA loadings, enabling the calculation of loads on the pipe and liner based on selected loading.

Soil Overburden : For deep pipes, CLinT optionally supports tunnel loading calculations per ASCE 27-17.

Material Properties: Both CLinT and CLinT/SL come with generic lining products and material properties. Users can customize these to match specific products and properties used in their projects.

Integrated Selection and Completion of Design Procedures: The MOP 145 method includes two design procedures in Part 1 for evaluating stability and material strength under groundwater pressure (critical and subcritical). It includes additional procedures in Part 2 for assessing material strength under deferred ovalization in flexible and cracked rigid pipes, and in Part 3 for evaluating stability and material strength under all loads for severely deteriorated pipes. CLinT automatically performs all applicable procedures to ensure that all design requirements are met.

Intuitive Data Input: The software features a well-organized data entry interface with drop-down menus and a minimal number of input fields, simplifying the user experience.

Automatic Calculations: Once all parameters are entered, a single click on the CALCULATE button initiates the automatic calculation process.

Clear Outputs: After calculations, users can generate two types of reports: a concise one-page summary and a detailed calculations report. Both reports include a customizable cover page for adding project information.

User Assistance: On-screen tips and information buttons guide users through data entry and calculations, while visual aids in the software and reports enhance understanding.

CLinT calculators perform calculations based on the provided input data. As such, the programs are offered without any warranties or guarantees regarding the reliability of results for specific projects. It is essential for users to understand that the selection of input data is critical to calculating a liner thickness that will function effectively under the given conditions and throughout the design life. Additionally, CLinT/SL does not verify liner stability during the grouting process. It is the USER’S RESPONSIBILITY to ensure that the thickness calculated in CLinT/SL is adequate to withstand external grout pressure during installation.
