As an expert in mechanical engineering and manufacturing, I can tell you that an NPT thread refers to a specific type of thread used in the United States and Canada, known as the National Pipe Thread. It's a tapered thread that is used to seal pipes and pipe fittings when they are screwed together.
NPT threads are designed to be used with a sealant, such as pipe dope or Teflon tape, which fills the gaps between the threads to create a watertight seal. The taper of the thread, which is typically 1/2 inch per foot, allows for a stronger and more secure connection when the threads are tightened.
The NPT standard is defined by the American National Standards Institute (ANSI) and is used in various applications, including plumbing, fire protection, and natural gas systems.
Here's the English explanation followed by the Chinese translation:
English Answer:
An NPT thread is a National Pipe Thread, which is a tapered thread commonly used in the United States and Canada for joining pipes and fittings with a seal. The thread is designed to mate with a sealant, such as pipe dope or Teflon tape, to ensure a watertight seal. The thread's taper is approximately 1/2 inch per foot, which contributes to a strong and secure connection when tightened. The NPT standard is set by the **American National Standards Institute (ANSI)** and is utilized in plumbing, fire protection, and natural gas systems.

National Pipe Thread Taper (NPT) is a U.S. standard for tapered threads used on threaded pipes and fittings. In contrast to straight threads that are found on a bolt, a taper thread will pull tight and therefore make a fluid-tight seal.
