Rajsagar Steel PVT. LTD offers steel metal pipes in various sizes and schedules. Pipe size indicates the nominal diameter of the pipe, whereas pipe schedule relates to the thickness of the pipe walls. According to the requirements of projects, our clients can select from a range of schedules and sizes, ensuring the best possible performance and longevity for their applications.
Pipe schedule determines the thickness of pipes used in various applications. It categorizes pipes into standardized types like Schedule 40 and Schedule 80, where lower schedules have thinner walls suitable for less demanding tasks, while higher schedules feature thicker walls for more robust applications such as high-pressure systems and industrial settings.

Pipe size refers to the nominal diameter of a pipe, typically measured in inches (in) or millimeters (mm). It indicates the internal diameter of the pipe and is essential for determining the flow capacity and suitability for various applications. Pipe size charts provide a comprehensive reference for understanding the relationship between pipe dimensions, flow rates, pressure ratings, and end-use applications.
Exp, in plumbing, knowing the pipe size is crucial for proper installation and ensuring adequate water flow. Similarly, in industrial settings such as oil and gas, chemical processing, or HVAC systems, selecting the correct pipe size is vital for efficient operation and safety.

Pipe size refers to the pipe's nominal diameter, while Pipe Schdule (SCH) indicates the wall thickness. SCH helps maintain the compatibility and standards that are essential for durability and pressure ratings.
| Pipe Schedule | Pipe Size |
| Indicates wall thickness: Lower number = thinner wall; higher number = thicker wall, often correlating with higher pressure capability. | Represents pipe diameter. Larger size = more flow capacity. |
| Higher SCH indicates stronger pipes, suitable for higher pressures and stresses. | Larger size pipes can handle greater flow rates and volumes of fluid. |
| Common in industries needing high-pressure containment like oil and gas, chemical processing. | Used in plumbing, irrigation, HVAC, and general fluid transport. |
| Thicker pipes (higher schedule) often cost more due to increased material and manufacturing requirements. | Larger pipes tend to be more expensive due to greater material usage. |
| Thicker-walled pipes (higher schedule) are less flexible, impacting maneuverability during installation. | Larger pipes may be less flexible and more challenging to install in confined spaces |
| SCH 10: 1/8" - 48" SCH 20: 1/8" - 48" SCH 40: 1/8- 24" SCH 80: 1/8" - 24" SCH 160: 1/8" - 12" | Pipe sizes can range from 1/8" to 48" in diameter, varying by SCH for different wall thicknesses and pressure ratings. |
