All About NPT Threads
National Pipe Thread also commonly referred to as NPT is simply the threading done on pipe.
It is the standard threading especially in the USA on the threading on pipes, pipe fittings and also tubes.
It is a norm that has ensured that all threads are of right spacing, tapering pattern, angle and depth making sure that they offer the secure tightening needed on different applications.
The NPT threads will also come with specified distances between all the threads and are measured in inch fractions.
The threads distance range between 1/8 and 2 inches and the small threads are mostly for gases and air which need to be compressed and the larger threads are suitable for different kinds of pipes normally used in waste management and water systems.
The threading on any pipe or tube is important since it will determine the seal provided.
This means that the threads need to be accurate and efficient for the applications.
With the right threads offering the right kind of seal, the transportation or sensitive materials has been made economical and safe in every sense.
The variations that could occur on the threads are mostly as a result of minor errors done on the specifications.
However, these minor variations can lead to huge errors since the pipes do not have that secure connection thus making it possible for dangerous leakages to occur.
The NPT norms therefore need to be adhered to correctly.
The industry also has standardized thread angle normally standing at 60 degrees.
This kind of standardization has ensured that all the valves, connectors and clamps remain at a matching similar angle.
Threading patterns also come in parallel and tapering designs with the parallel having round ring running on the inner or outer tube or pipe diameter.
The tapering on the other hand have spiral shapes or either lower or higher diameters on the surface.
The choice will depend on the application the NPT threads are needed for.
The NPT thread standardization has made it easy for people to get the right ones for all the piping or tubing needs that they have.
It is however of great importance to ensure that you get all your fittings from reputable dealers to ensure that you get superior quality which in turn will help in keeping dangerous errors at bay.
You can have the threads tested before you can use them on the intended applications.
