In the industrial piping industry, precision is everything. Whether you’re working on a complex oil & gas project or managing an infrastructure pipeline system, having a clear understanding of steel density and pipe schedules is vital. In this blog, we’ll break down two essential tools and concepts used by engineers and project managers worldwide: the Steel Density Conversion Calculator (LB IN³ / KG M³ / LB FT³) and Schedule XS Pipe dimensions, weight, and thickness.
If you’re in the market for reliable and high-quality steel piping, Tianjin United Steel Piping Co., Ltd. (TUSPIPE) is your trusted partner. Let’s explore how steel density and Schedule XS pipe specifications can support your next project.
What is Steel Density and Why Does it Matter?
Steel density refers to the mass of steel per unit volume. It is a fundamental property used to calculate the weight of steel products based on their volume. Engineers and designers rely on steel density values to estimate pipe weights, plan transportation logistics, and ensure the overall structural integrity of a piping system.
The standard density of carbon steel is approximately:
- 7.85 g/cm³
- 7850 kg/m³
- 0.284 lb/in³
- 490 lb/ft³
However, density may vary slightly depending on the steel composition (e.g., stainless steel, alloy steel).
Steel Density Conversion Calculator: LB IN³ / KG M³ / LB FT³
To simplify engineering calculations and cross-reference different unit systems, a Steel Density Conversion Calculator is a practical tool. It helps convert between:
- Pound per Cubic Inch (lb/in³)
- Kilogram per Cubic Meter (kg/m³)
- Pound per Cubic Foot (lb/ft³)
This tool is especially useful when working on international projects where metric and imperial units are used interchangeably.
🔧 How to Use the Steel Density Conversion Calculator?
- Input the known density value in one unit (e.g., lb/in³).
- Select the target unit for conversion (e.g., kg/m³ or lb/ft³).
- Click ‘Convert’ to get the accurate conversion.
At TUSPIPE, we understand the challenges faced by engineers and procurement teams. That’s why our team can provide you with technical data, including steel density charts and conversion support, to assist with your material selection and design accuracy.
What is Schedule XS Pipe?
In steel piping, the term “schedule” refers to the wall thickness of the pipe. The higher the schedule number, the thicker the pipe wall.
Schedule XS (also known as Extra Strong) is a standardized pipe schedule used for high-pressure and high-temperature applications. Schedule XS pipes offer increased durability, pressure handling capacity, and are often used in:
- Oil and gas transmission lines
- Petrochemical plants
- Power generation units
- High-pressure steam systems
🔍 Schedule XS Pipe vs Schedule 40 and Schedule 80
- Schedule 40 – Standard thickness, commonly used for low-pressure applications
- Schedule 80 – Thicker wall than Schedule 40, used for moderate pressure
- Schedule XS – Extra Strong, wall thickness is equal to Schedule 80 for sizes up to 8 inches, but differs in larger sizes
Schedule XS Pipe: Dimension, Weight, and Thickness
Let’s look into typical values of Schedule XS pipes. The wall thickness and weight per foot are crucial factors when planning for load handling and system design.
✅ Sample Schedule XS Dimensions (For Carbon Steel Pipes)
| Nominal Pipe Size (NPS) | Outside Diameter (OD) | Wall Thickness (in) | Weight (lb/ft) |
| 2″ | 2.375″ | 0.218″ | 5.62 lb/ft |
| 4″ | 4.5″ | 0.337″ | 14.97 lb/ft |
| 6″ | 6.625″ | 0.432″ | 28.57 lb/ft |
| 8″ | 8.625″ | 0.5″ | 43.39 lb/ft |
| 10″ | 10.75″ | 0.594″ | 62.58 lb/ft |
These values may vary slightly depending on the material grade and manufacturing process. For exact values, refer to the mill test certificates or consult with the technical team at TUSPIPE.
Why Choose Schedule XS Pipe?
- High Pressure Resistance
Schedule XS pipe can withstand high internal and external pressures, making it suitable for demanding industrial environments.
- Durability
The extra wall thickness improves corrosion resistance and extends the service life of the pipeline.
- Code Compliance
Many industrial standards and codes (ASME, ASTM, API) specify Schedule XS pipes for specific applications. TUSPIPE ensures all products meet or exceed global compliance requirements.
Applications of Schedule XS Steel Pipes
At TUSPIPE, our Schedule XS pipes are widely used across industries:
- Oil & Gas Pipelines: Where strong pipes are needed to handle crude and gas under high pressure.
- Boiler Systems: For high-temperature, high-pressure steam transfer.
- Chemical Plants: For transporting hazardous or reactive substances.
- Infrastructure Projects: Including bridges and high-load supports.
