What Essential Things You Should Know About Pipe Fittings?

Pipe fittings are components that are used for joining pipe sections together with other fluid control products like valves and pumps for creating pipelines. Now, there are many different types of fittings used for connecting pipes.

They may be weldless, welded or threaded, mechanically joined, or chemically adhered, to name the most common mechanisms, based on the materials of the pipe. It is ideal to find one of the best non-welding pipe and components suppliers for buying high-quality weldless fittings, MAF pipe fittings, retain flange, and many others. Below, I’m going to share some important things about pipe fittings that you should know.

Pipe Fitting Materials

There are so many different types of materials that are used for making fittings. So, you can choose one based on your industrial requirement and budget. Here are some materials that are used for making fittings, such as:

  • Cast and malleable iron
  • Steel and steel alloys
  • Nonferrous
  • Glass
  • Plastic, and many others

Types of Pipe Fittings: Applications and Industries

Thread Type

There are many pipe applications that use threaded fittings. They are basically tapered and are designed to be right-hand threads. But there are also some left-hand threaded available.


These small, weldable branch fittings strengthen the pipe where a hole is made, eradicating the need to add emphasis. There are different types of these fittings available, covering butt- and socket-welded styles, thread-on varieties, as well as some special designs which allow connections at elbows, etc.

Welding Process

Pipe ends and flanges are prepared for butt welding according to pipe-wall thickness. There are many different types of welding processes that are used for welded fittings. And one of them is a socket weld that is used for thinner-walled pipes. Sometimes pipes are preheated for welding and heat-treated after for relieving heat stress.

The requirement for proper pipe-end preparation and the need for careful fit prior to joining butt welded fittings make the use of socket-weld fittings appealing.

Non-Welded Fittings

There are also non-welded fittings or no weld pipe connectors available as substitutes to the traditionally welding piping systems. Using a combination of swaged mechanically attached pipe fittings with the cold bending of pipe or tubing to eliminate the stresses to the pipeline from the welding operation. This solution also helps to reduce costs and can offer a modular system that is dissembled or modified easily when you need it.

Fitting Shapes and Styles

Most fitting silhouettes are palpable by their name. The normally available ones include:

  • Caps
  • Plugs
  • Nipples
  • Elbows
  • Tees
  • Wyes
  • Crosses
  • Unions
  • Bushings
  • Reducers
  • Adapters

Pipe plugs or caps can be used to cover the trimmings of the pipe. There are some forms of high-pressure plugs that are used for temporarily sealing off pipe ends to enable pressure testing in pipelines and pressure vessels while eradicating the requirement to accomplish conformist welding operations in order to complete these tests.

Elbow can be used in bends, and return bends are used for moving fluid through a full 180° change in direction. Small lengths of threaded pipe are known as nipples. And bushings are used for changing pipe diameters, as are reducers. Terms such as street and service define fixtures with an exterior thread. While unions are used for connecting a threaded pipe without the need to turn either pipe. Adapters allow the system to change between two materials such as between plastic and metal pipe.


The above-mentioned information will provide a basic understanding of pipe fittings, their materials, specific types, and applications. You can find one of the best non-welded piping system suppliers for buying the best-quality weldless fittings, MAF pipe fittings, retain flange, and many other components.
