Dimensions and Sizing Standards for Steel Pipe
Knowing the size of a 2 inch steel pipe is important. IL “2 inch” size is called the nominal pipe size (NPS). This is a global standard for naming pipe sizes. But, the real outside diameter (OD) of a 2 inch steel pipe is 60.3 mm. This size follows rules like ASME B36.10M and ASME B36.19M. These rules also decide the wall thickness, which changes with the pipe schedule. Per esempio, Schedule 40 pipes have walls 3.91 mm thick. Schedule 80 pipes are thicker, with walls of 5.54 mm.
Here’s a simple table to compare sizing standards:
Standard | Description |
|---|---|
ASME B36.10M | Lists sizes for seamless and welded steel pipes. |
ASME B36.19M | Focuses on stainless steel pipe sizes. |
NPS | Names pipe sizes, mainly for pipes smaller than NPS 12. |
Schedule | Shows pipe wall thickness, like Schedule 40 or 80. |
Always check the pipe size and schedule to match your project needs.

Both types are tested for quality using methods like ultrasonic and X-ray tests. Choose welded or seamless pipes based on strength, pressure needs, and budget.
Pressure Ratings and Wall Thickness of Steel Pipes
When picking a steel pipe, know its pressure rating and wall thickness. These decide how much pressure the pipe can handle and how strong it is. Thicker walls make pipes stronger and better for high-pressure jobs.
Steel pipes are grouped by schedules, which show wall thickness. Ad esempio, Schedule 40 pipes have medium-thick walls. Schedule 80 and Schedule 160 pipes have thicker walls for higher pressure. Below is a table with pressure ratings for 2 inch steel pipes:
Pipe Schedule | PSI Rating (approximate) |
|---|---|
Schedule 40 | 700-2,000 PSI |
Schedule 80 | 1,200-3,000 PSI |
Schedule 160 | 2,500-6,000 PSI |
Pick the right schedule based on your pressure needs. Schedule 40 works for low-pressure systems. High-pressure systems, like in factories or oil jobs, may need Schedule 80 or 160. Always check the pressure rating to match your project.
Thicker walls also mean heavier and pricier pipes. But they are stronger and last longer. Think about weight, costo, and strength when choosing a pipe.
Corrosion Resistance: Coatings and Treatments for Steel Pipes
Rust can shorten a steel pipe’s life. To stop this, pipes get special coatings or treatments. These protect against rust, prodotti chimici, and harsh weather. This is key for pipes in wet or tough conditions.
