A pipe fitting is used in the plumbing system to join multiple pipes of the same size or different sizes, to regulate the flow or to measure the flow.
Various types of pipe fittings are available in plumbing systems for different purposes and functions. Types of Pipe Fittings include Elbow, Reducer, Tee type, Cross type, Coupling, Unions, Adaptors, Olet, Plug, and Cap.
The basic purposes of any pipe fitting are connecting the bores of two or more pipes or tubes, connecting pipe sections, connecting a pipe to a different apparatus, changing the direction of fluid/liquid flow, maintaining or regulating the flow, closing and sealing a pipe.
Pipe Fittings are used in various applications due to its strength, flexibility, very good flow rates and high chemical resistance. Pipe Fittings are used in a wide range of applications some of which include Chemical / Petrochemical industries, Food, Beverage, and Dairy Industry, Oil and Gas, Power Generation, Pulp and Paper, Marine & dredging, Sanitation. In all these industries pipes are used to transfer liquid, gas, slurries, and other solids and fluids from one area to another and accordingly different categories of pipe fittings are used. Thus, pipe fittings play a vital role in the proper functioning of pipe and tubes in various applications.
Pipe Fittings are sized with respect to pipe size. In Nominal pipe size (NPS) & also as a Diameter Nominal (DN). Thicknesses are marked in schedule no. Fittings generally have a higher thickness than the pipe to avoid any rejection due to thickness reduction during manufacturing.
Pipe fittings are identified by their material of construction, inner and outer diameter of the pipe, and the type of fitting whether threaded or slip, male or female.
Material, Size, Temperature and Pressure Ratings, Durability, Standards etc.
Pipe fittings are classified based on end connection as Socket weld fittings, Screwed end fittings, Beveled end or Butt weld fittings, Spigot socket fittings, Buttress end fittings.
