1/2 inch NPT to MM: Conversion and Equivalent Dimensions
In the world of piping and tubing, understanding the dimensions and conversions between different units is crucial. One common conversion that often arises is from 1/2 inch NPT (National Pipe Taper) to millimeters (mm). In this article, we will delve into the conversion, equivalent dimensions, and other essential details.
What is NPT?
NPT (National Pipe Taper) is a standard for tapered threads used on pipes and fittings in the United States. It is commonly used for pipes, valves, and fittings in various industries, including oil and gas, chemical processing, and power generation.
1/2 inch NPT Dimensions
The dimensions for 1/2 inch NPT are as follows:
- Major diameter: 0.83 inches (21.08 mm)
- Minor diameter: 0.62 inches (15.75 mm)
- Threads per inch (TPI): 14
- Pitch: 1.783 mm
Conversion to MM
To convert 1/2 inch NPT to millimeters, we need to consider the major and minor diameters.
- Major diameter: 21.08 mm
- Minor diameter: 15.75 mm
Equivalent Dimensions
Here are some equivalent dimensions for 1/2 inch NPT:
- BSP (British Standard Pipe): 1/2 inch BSP is equivalent to 1/2 inch NPT
- Metric: M18 x 1.5 (a common metric thread size)
