Pipes play an integral role in various industries and applications, serving as conduits for fluids, gases, and more. Among the myriad of pipe specifications available, Schedule 20 pipes stand out for their specific characteristics and applications.
What is Schedule 20 Pipe?
Schedule 20 pipe is a designation used in the piping industry to define the wall thickness of pipes. This standard is part of the ASME/ANSI B36.10 specification, which categorizes pipes based on their wall thickness and nominal pipe size (NPS). Unlike Schedule 40 or Schedule 80 pipes, Schedule 20 pipes have a relatively thinner wall.
Schedule 20 Pipe Thickness in mm
The thickness of Schedule 20 can vary depending on the material and manufacturing standards. However, as a general guideline, the nominal thickness of a Schedule 20 pipe can range from around 6.35 mm (1/4 inch) to 7.92 mm (5/16 inch), though these measurements might differ based on the specific requirements and standards.
Pipe Thickness Chart
Here's a rough comparison chart between Schedule 20 and Schedule 40 pipes to illustrate their differences in wall thickness:
ScheduleWall Thickness (in mm)Common ApplicationsSchedule 206.35 - 7.92Low-pressure applications, plumbing, light-duty systems schedule 403.38 - 4.55General-purpose, residential and commercial plumbing, moderate pressure applications
Please note that these values are approximate and can vary based on material, manufacturing standards, and specific pipe dimensions.
How Thick is Schedule 40 Pipe?
Schedule 40 pipes are among the most commonly used pipes. Their wall thickness typically ranges from approximately 3.38 mm (1/8 inch) to 4.55 mm (3/16 inch), making them thicker than Schedule 20 pipes. These pipes are favored for applications requiring a balance between strength and cost-effectiveness.
Applications of Schedule 20 Pipes
Due to their thicker walls compared to other schedules, Schedule 20 are suitable for specific applications that don't necessitate heavy-duty strength but require more substantial thickness than lighter schedules. These pipes find use in:
- Low-pressure Systems: Such as drainage, waste, or vent systems in buildings.
- Plumbing: For residential or light commercial plumbing needs where high pressure isn’t a concern.
- General Conduit: Where moderate protection and conveyance of fluids or gases are required.
Conclusion
Understanding the nuances of pipe schedules and their respective thicknesses is crucial when selecting the right pipes for any project or application. While Schedule 20 pipes offer a balance between thickness and application suitability for low-pressure systems, Schedule 40 pipes provide a sturdier option for more demanding applications.
When choosing pipes, it’s essential to consider factors like pressure requirements, material compatibility, and structural needs to ensure optimal performance and longevity.
In essence, the selection between Schedule 20 and Schedule 40 pipes often hinges on the specific demands of the project, balancing requirements with the capabilities of the pipe schedules available.
