In industrial piping systems, selecting the right pipe schedule is critical for ensuring performance, durability, and safety. One of the heaviest and most robust pipe schedules available is Schedule 160 Steel Pipe. Known for its thick wall and high-pressure handling capacity, Schedule 160 steel pipe is commonly used in demanding industrial applications where strength and pressure resistance are non-negotiable.
In this guide, we’ll explore everything you need to know about Schedule 160 steel pipes, including their dimensions, applications, weight calculation, and how they compare with other schedules. Whether you’re working on high-pressure piping systems or sourcing steel pipes for your next project, understanding the specifications of Schedule 160 can help you make an informed decision.
What is Schedule 160 Steel Pipe?
Schedule 160 steel pipe refers to a specific wall thickness classification in the ANSI/ASME B36.10M standard. The “schedule” of a pipe relates to its wall thickness and, consequently, its ability to withstand internal pressure. As the schedule number increases, the wall thickness also increases.
Schedule 160 is among the thickest available schedules for carbon steel pipes. Due to its substantial wall thickness, it can handle extremely high pressure, making it suitable for critical systems like power plants, oil & gas refineries, and heavy industrial applications.
Key Features of Schedule 160 Steel Pipe
- High Pressure Resistance
Schedule 160 steel pipe is designed to carry high-pressure fluids without risk of rupture or deformation. This makes it ideal for pressurized systems and hydraulic applications. - Thicker Wall
Compared to Schedule 40 or 80, Schedule 160 has a much thicker wall, allowing for superior strength and durability in harsh environments. - Available in Multiple Sizes
Schedule 160 is available in standard nominal pipe sizes, typically ranging from 1/8 inch up to 12 inches. However, availability may vary depending on the steel grade and manufacturing capability. - Material Versatility
Schedule 160 pipes are typically made from carbon steel, alloy steel, or stainless steel, depending on the application requirements.
Schedule 160 Steel Pipe Dimensions
Understanding the dimensions of Schedule 160 steel pipes is essential for planning and compatibility. Here’s a quick example of dimensions for selected nominal pipe sizes:
| Nominal Pipe Size (NPS) | Outside Diameter (OD) | Wall Thickness (Sch 160) | Inside Diameter (Approx.) |
|---|---|---|---|
| 1 inch | 1.315 in (33.4 mm) | 0.250 in (6.35 mm) | 0.815 in (20.7 mm) |
| 2 inch | 2.375 in (60.3 mm) | 0.436 in (11.07 mm) | 1.503 in (38.2 mm) |
| 4 inch | 4.5 in (114.3 mm) | 0.674 in (17.12 mm) | 3.152 in (80.1 mm) |
| 6 inch | 6.625 in (168.3 mm) | 0.864 in (21.95 mm) | 4.897 in (124.4 mm) |
For precise project planning, it’s important to refer to the full ASME B36.10M table or consult with your steel pipe supplier for detailed sizing.
Weight of Schedule 160 Steel Pipe
The weight of a steel pipe depends on its size and wall thickness. Since Schedule 160 pipes have thick walls, they are significantly heavier than lower schedule pipes.
To simplify weight estimation, Tuspipe offers a steel pipe weight calculator that lets you determine the weight per meter or foot based on your pipe’s dimensions. This tool is particularly useful when planning for transportation, support structures, or ordering raw materials.
Example:
A 6-inch Schedule 160 steel pipe weighs approximately 103.3 kg/m (69.4 lb/ft).
Applications of Schedule 160 Steel Pipe
Due to its strength and pressure resistance, Schedule 160 steel pipe is favored in:
- High-pressure steam systems
- Oil and gas transmission lines
- Power generation facilities
- Chemical processing plants
- Industrial hydraulic lines
- Heavy machinery manufacturing
These applications demand robust piping that can perform under extreme pressure, temperature, or corrosive environments—making Schedule 160 the go-to choice. In many of these systems, specialized tools are also used to inspect pipeline interiors and ensure long-term performance and safety.
Schedule 160 vs. Other Pipe Schedules
When choosing the right pipe for a system, it’s crucial to understand how Schedule 160 compares to other common pipe schedules like Schedule 40 and Schedule 80.
| Schedule | Wall Thickness | Pressure Rating | Weight | Use Case |
|---|---|---|---|---|
| Sch 40 | Thin | Low | Light | General plumbing, low-pressure systems |
| Sch 80 | Medium | Moderate | Medium | Industrial, water supply, structural |
| Sch 160 | Thickest | High | Heavy | High-pressure industrial systems |
Conclusion: If your project requires high strength and pressure resistance, Schedule 160 steel pipe is the most reliable choice.
