Advantages and Applications of PP Fitting

Recommended Posts

The pp fitting is used in piping systems to change direction of the liquid flow, connect pipes of different sizes, change pipe diameter and branch the liquid flow from one pipe into multiple pipes.

Integrating fittings into piping systems is a various important task. After all, it’s at the connections between pipes where the system is most susceptible to leaks and failure. As such, many pipe fitting connection methods require special training to be executed.

From soldering, to threading to brazing, there are many types of connection methods. One of the most popular, however, is welding.

Welded pipe fittings are much like what their name suggests: the fittings are welded directly onto the pipes. Trained and licensed professionals often carry out this difficult feat, fusing the fitting to the pipe by carefully melting their metals together. Usually, the fitting and the pipe need to be made of the same or very compatible materials. After the welding is complete, the fittings are often tested to ensure their integrity.


Welded pipe fittings offer many advantages. The welding process makes them permanently leakproof. The continuity between the pipe and the fitting increases the strength of the system. Pressure losses and turbulence are reduced by the system’s smooth inner surface and gradual direction change. In addition, a welded system uses space more efficiently than some other connecting methods.

Types of Welded Fittings

There are many different types of pp fitting. We offer all of the most varieties, including the following:

45 Elbow
Reducing Elbow
Reducing Tee
Barred Tees
90 Elbow LR & SR
Cushion & Target
Concentric Reducer
Eccentric Reducer
Stub End
180 Return Bend
3R & 5R Bends
Reducing Lateral
Swage Nipple

Though they are very effective, welded pipe fittings can be costly because of the skilled labor they require. Therefore, they are usually only used in applications that require high performance. These applications include chemical and nuclear reactors, as well as shipbuilding.
