Here is a table showing the standard 2 inch stainless steel pipe dimensions and weights according to ASME B36.19:

You can see that the outside diameter remains constant, while the wall thickness and weights change with the schedule.

Wall Thickness and Schedules

The wall thickness of a 2 inch stainless steel pipe depends on its schedule. The schedule number tells you how thick the pipe wall is. Higher schedule numbers mean thicker walls and higher pressure ratings. For example, Schedule 5S has a wall thickness of 0.065 inches, while Schedule 80S has a wall thickness of 0.218 inches. These differences affect both the strength and the weights of the pipes.

You will often see pipes labeled as Standard (STD), Extra Strong (XS), or Double Extra Strong (XXS). These labels match up with certain schedule numbers. For 2 inch stainless steel pipes, the most common schedules are 5S, 10S, 40S, and 80S. The ASME and ASTM standards make sure these dimensions and weights stay consistent for safety and compatibility.

Note: The schedule you choose should match the pressure and mechanical requirements of your project.

Weight and Length Options

The weights of 2 inch stainless steel pipes change with wall thickness and schedule. For example, a Schedule 40S pipe weighs about 5.44 kg per meter (or 3.66 lbs per foot). The table below shows typical dimensions and weights for a 2 inch stainless steel pipe:

You can buy these pipes in standard lengths, such as 10 feet or 20 feet. Some suppliers offer custom lengths to fit your needs. The weights and dimensions help you plan for handling, installation, and support.

When you compare different stainless steel pipe dimensions and weights, you can make better choices for your application. The ASME standards help you find the right pipe for your needs, whether you work in construction, manufacturing, or plumbing.

Understanding Specifications

Nominal Size vs. Outside Diameter

When you look at a stainless steel pipe size, you might expect the number to match the actual diameter. In reality, the nominal pipe size is a dimensionless label that helps you identify and order pipes, but it does not equal the true outside diameter. For example, a 2 inch nominal pipe size actually has an outside diameter of 2.375 inches. This difference comes from standards like ASME B36.19 and ASME B36.10, which set the rules for how pipes are labeled and measured. The outside diameter is the real measurement from one edge of the pipe to the other, which matters for fitting and installation. The inside diameter changes depending on the wall thickness, but the outside diameter stays the same for each nominal pipe size. Outside North America, you may see pipes labeled with DN (Diametre Nominal), which is also a dimensionless number based on the outside diameter in millimeters.

Note: Always check both the nominal pipe size and the actual outside diameter before you order or install pipes. This helps you avoid costly mistakes.

Pipe Schedule Meaning

The schedule of a pipe tells you how thick the wall is. You will see numbers like Schedule 10S, 40S, or 80S. These numbers do not have units. A higher schedule means a thicker wall. The schedule affects the inside diameter, but the outside diameter stays fixed for each nominal pipe size. The wall thickness is important because it changes how much pressure the pipe can handle. For example, a 2 inch Schedule 40S pipe has a thicker wall than a Schedule 10S pipe, so it can hold more pressure. The schedule number comes from a formula that uses the internal pressure and the strength of the pipe material. For stainless steel pipe, the schedule helps you match the pipe to your project's needs for strength and safety.

Tip: Choose the right schedule based on the pressure and mechanical demands of your system.

Seamless vs. Welded Stainless Steel Pipe

You will find two main types of pipes: seamless and welded. Each type has its own strengths and best uses.

• Seamless pipes have no weld seam. Manufacturers make them by extruding or piercing a solid billet. This gives seamless pipes uniform strength and higher pressure ratings. You should use seamless pipes for high-pressure steam, oil and gas, or chemical processing.

• Welded pipes are made by rolling and welding steel strips or plates. They have a weld seam, which can be a weak point, but modern welding methods make them strong and reliable. Welded pipes cost less, come in larger sizes, and work well for water distribution, building supports, and general construction.

• Seamless pipes offer better pressure resistance and longer corrosion life. They cost more and take longer to produce. Welded pipes are more affordable and available quickly, but you need to inspect the weld seam for quality.

• Choose seamless pipes when you need top performance and safety. Pick welded pipes when you want cost savings and size options.

Alert: For critical systems with high pressure or safety needs, seamless pipes are the best choice. For most building or low-pressure uses, welded pipes offer a good balance of cost and performance.
