Understanding 1 1/2" Stainless Steel Pipe Dimensions

1 1/2" stainless steel pipe is a common choice for various applications due to its corrosion resistance and durability. When working with this type of pipe, it's essential to understand the different dimensions involved. This article will guide you through the key measurements:

Nominal Pipe Size (NPS)

The most common way to refer to 1 1/2" stainless steel pipe is through its Nominal Pipe Size (NPS). NPS refers to the approximate internal diameter of the pipe. In this case, 1 1/2" NPS indicates a pipe with an internal diameter of approximately 1.5 inches.

Outer Diameter (OD)

The outer diameter (OD) of a 1 1/2" stainless steel pipe is 1.900 inches. This measurement is crucial for selecting fittings and other components that will connect to the pipe.

Wall Thickness (WT)

The wall thickness (WT) of 1 1/2" stainless steel pipe varies depending on the schedule, which defines the pipe's pressure rating. Here are some common schedules and their corresponding wall thicknesses:

  • Schedule 10: 0.109 inches
  • Schedule 40: 0.145 inches
  • Schedule 80: 0.180 inches
  • Schedule 160: 0.250 inches

The higher the schedule, the thicker the wall and the higher the pressure rating. Choosing the appropriate schedule is essential for ensuring the pipe can withstand the intended pressure and working conditions.

Other Dimensions

In addition to these basic dimensions, there are other factors to consider when choosing 1 1/2" stainless steel pipe, such as:

  • Material grade: Different stainless steel grades offer varying levels of corrosion resistance and mechanical strength.
  • Pipe length: Pipes are typically available in various lengths, such as 20 feet or 40 feet.
  • End preparation: Pipe ends may be cut, beveled, or threaded depending on the specific application.

Understanding these dimensions and factors is crucial for selecting the right 1 1/2" stainless steel pipe for your project. By carefully considering the intended application and working conditions, you can ensure the pipe meets your requirements and provides reliable performance.
