What are Pipe Fittings?

 

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. Common types of pipe fittings include couplings, elbows, tees, crosses, flanges and unions.

 

Common Types of Pipe fittings

Various types of pipe fittings are available in plumbing systems for different purposes and functions. Types of piping 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, and closing and sealing a pipe.

Pipe Fittings are used in various applications due to their strength, flexibility, very good flow rates and high chemical resistance. Pipe Fittings are used in a wide range of applications, some of which include the Chemical / Petrochemical industries, Food, Beverage, and Dairy Industries, Oil and Gas, Power Generation, Pulp and Paper, Marine & dredging, and 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 pipes 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 for pipes generally have a higher thickness than the pipe to avoid any rejection due to thickness reduction during manufacturing.

 

Pipe Fitting FAQ

How are pipe fittings identified?

Pipe fittings are identified by their material of construction, the inner and outer diameter of the pipe, and the type of fitting, whether threaded or slip, male or female.

 

What should I consider for buying pipe fittings?

To buy pipe fittings, consider material, size, temperature and pressure ratings, durability, standards, etc.

 

How Pipe Fittings Are Classified Based On End Connections?

Pipe fittings are classified based on end connection as Socket weld fittings, Screwed end fittings, Beveled end or Butt weld fittings, Spigot socket fittings, and Buttress end fittings.


How Pipe Fittings are made?

Pipe fittings are typically made using processes such as forging, casting, or machining. The type of process employed depends on the complexity and size of the fitting. Forging is generally used to create more complex parts while casting and machining are used for simpler parts. Each process involves a series of steps that ensure consistent quality and precise dimensions.
