National Pipe Thread or NPT is a standard specification of screw thread, threaded pipes, and pipe fittings. NPT Fittings are well-known fittings that come in different shapes and sizes. These fittings can be easily assembled and are widely available in the market. The NPT Pipe Fittings are designed to influence the characteristics of the flow in gaseous and fluid media. These fittings rely on the deformation of threads to tightly secure the seal of the fittings. The NPT Threaded Fittings offer simple assembly without initiating any flaring of tubes, requiring seals, or using sleeves to connect the items.
These fittings are not suited for high-pressure applications. These NPT Adapter Fittings help connect piping components of different sizes or terminate the flow of the running system. These fittings ensure there is no leakage in the system. The NPT Hydraulic Fittings allow for the connection of different pipes, tubes, cylinders, and valves. These fittings allow for a change in direction, stoppage, mixing, and diversion of the media in the system. They are generally called mater angle, o-ring, and threaded connection types. The versatile NPT Swivel Fittings are very flexible and allow hoses or couplings to rotate, and move easily in the system. These fittings prevent any twisting and excessive bending of the fixtures. They help in extending the life of the piping grades and reduce maintenance costs, thereby increasing the efficiency of the system.
The NPT Fittings Dimensions are based around the ANSI and ASME B1.20.1 standard. This standard outlines the dimensions and tolerances for tapered threads for fittings and pipe types. The threads on these fittings range from 1 inch per diameter to 16 inches in length. The NPT Fittings Pressure Rating ranges between 10,000 psi to 15,000 psi in service. The sizes and the taper pipe dictate their inherent working range. NPT Elbow Fittings are designed as long or short radiuses and can change the direction of the flow of media by 45 or 90-degree turns. The NPT End Fittings are placed at the end of the piping equipment and help in connecting the grade effectively to other modules.
