When working with CS (Chlorinated Polyvinyl Chloride) pipe schedules, understanding the pipe sizes and their corresponding dimensions is crucial. One of the most convenient ways to grasp this information is by referring to a CS pipe schedule chart in millimeters (mm). This article provides a comprehensive guide to understanding and using these charts, with a focus on the PDF format for easy reference and printing.

CS pipes are widely used in various industries due to their durability, corrosion resistance, and low maintenance costs. The pipe schedule chart is a vital tool for engineers, designers, and installers to ensure the correct pipe size is selected for a given application, based on factors such as flow rate, pressure, and temperature.

Understanding CS Pipe Sizes
CS pipe sizes are typically expressed in millimeters (mm) or inches, with the most common sizes ranging from 20 mm to 1200 mm. The pipe schedule chart lists these sizes in a tabular format, along with their corresponding dimensions, such as outside diameter (OD), inside diameter (ID), wall thickness, and weight per meter.

It's essential to note that the pipe schedule chart may vary slightly between manufacturers, but the general format and information provided remain consistent. Always refer to the specific manufacturer's chart for the most accurate information.
Reading a CS Pipe Schedule Chart in MM

To read a CS pipe schedule chart in millimeters, follow these steps:
- Locate the desired pipe size in the first column of the chart, typically labeled "Nominal Size" or "Pipe Size".
- Find the corresponding row for the selected pipe size, which contains the relevant dimensions and properties for that specific pipe.
- Identify the required dimension, such as OD, ID, or wall thickness, in the appropriate column of the chart.
For example, if you're looking for the outside diameter of a 100 mm CS pipe, you would find the row with "100" under the "Nominal Size" column and then read the value in the "Outside Diameter (mm)" column.

Using a CS Pipe Schedule Chart in PDF Format
PDF (Portable Document Format) is a convenient and widely-used format for CS pipe schedule charts. The advantages of using a PDF chart include:
- Easy to print and distribute
- Consistent formatting and appearance across different devices and platforms
- Ability to search for specific pipe sizes or dimensions using the PDF viewer's search function

To use a CS pipe schedule chart in PDF format, simply open the file using a PDF viewer, such as Adobe Acrobat Reader or a web browser with built-in PDF support. Navigate the chart using the viewer's zoom, pan, and search functions to find the required information quickly and efficiently.
CS Pipe Schedule Chart Examples




















To illustrate the use of CS pipe schedule charts, let's consider two examples: selecting a pipe based on flow rate and determining the wall thickness for a given pressure rating.
Selecting a CS Pipe Based on Flow Rate
To select the appropriate CS pipe size for a given flow rate, follow these steps:
- Determine the required flow rate in liters per second (L/s) or cubic meters per hour (m³/h).
- Consult a hydraulic calculation software or chart to find the required pipe velocity for the given flow rate and fluid properties.
- Using the CS pipe schedule chart, find the pipe size that provides the required velocity with a reasonable head loss (pressure drop) and wall thickness.
For example, if the required flow rate is 0.05 m³/s (1800 m³/h) and the fluid has a specific gravity of 1, the required pipe velocity might be around 2 m/s. Using a CS pipe schedule chart, you would find that a 200 mm CS pipe provides a velocity of approximately 2.1 m/s with a reasonable head loss and wall thickness.
Determining Wall Thickness for a Given Pressure Rating
To determine the required wall thickness for a CS pipe operating at a specific pressure, follow these steps:
- Determine the maximum allowable pressure (MAP) or operating pressure for the pipe, typically expressed in bar or Pascal (Pa).
- Using the CS pipe schedule chart, find the pipe size that meets the required pressure rating. The chart should list the pressure rating for each pipe size, usually expressed as a range (e.g., "PN 10-16" for a pipe with a pressure rating between 10 and 16 bar).
- Once you've selected the appropriate pipe size, the chart will also provide the corresponding wall thickness for that specific pipe.
For example, if the required pressure rating is 16 bar, you would find that a 100 mm CS pipe with a PN 10-16 rating has a wall thickness of 4.5 mm.
In the world of engineering and construction, having a clear understanding of CS pipe schedules is invaluable. By familiarizing yourself with these charts and their PDF format, you'll be well-equipped to make informed decisions about pipe selection, ensuring the optimal performance and longevity of your piping systems. Happy designing!
