NPT stands for National Pipe Thread, which is a standard for tapered threads used on threaded pipes and fittings. NPT threads are commonly used in the United States for joining pipes and fittings in various applications.
The pressure rating of NPT threads depends on several factors, including the material and the size of the thread. For specific pressure ratings, it is important to refer to the manufacturer’s specifications for the particular material and size of the pipe or fitting. Different materials, such as stainless steel, brass, or carbon steel, may have different pressure ratings for NPT threads. Please see below NPT pressure rating for SS316, brass and carbon steel material.
In industrial applications, it’s common to use sealants or thread tape on NPT threads to improve the seal and reduce the risk of leaks. It’s important to follow best practices for assembly and tightening to ensure a secure and leak-free connection. Additionally, considering the intended application and consulting relevant standards and guidelines can help determine the appropriate pressure rating for NPT connections in a specific context.
