What is the difference between a swage and a reducer?

What is the difference between a swage and a reducer?

The function of Swage nipples are the same as reducer the only difference is that they are generally used to connect butt welded pipe to a socket welded or screwed pipe. There are also available as Concentric and Eccentric type.

How many types of pipe reducers are there?

There are 2 types of standard reducers available: concentric and eccentric reducers. The concentric one, which resembles a cone, is used to join pipe sections on the same axis. The eccentric type has an edge which is parallel to that of the connecting pipe, which allows it to align with one side of the inlet.

What is the use of concentric reducer?

A concentric reducer is used to join pipe sections or tube sections on the same axis. The concentric reducer is cone-shaped, and is used when there is a shift in diameter between pipes. For example, when a 1″ pipe transitions into a 3/4″ pipe and the top or bottom of the pipe doesn’t need to remain level.

Why concentric reducer is used in pump discharge?

When are Eccentric and Concentric Reducers Used Concentric reducers are used where the pipework is vertically installed and at the discharge side of pumps. This prevents the forming of bubbles and limits the chance of damaging the propellers inside the pump because of the cavitation phenomenon.

Why do nipples swage?

Swage nipples are used to bring the flow of fluids from one pipe size to another pipe size. You can find swage nipples that are plain, beveled or with threaded ends. The function of swage nipple is to change pipe’s diameter and to connect two pipes of different sizes.

What is the difference between coupling and union?

But there is a difference between a coupling and a union in terms of black and galvanized pipe. A coupling is a solid fitting with female threads on the inside of both ends. A union is used when you are trying to join two pipes together that are fixed, thus unable to be turned.

Why suction is bigger than discharge?

The discharge pipe may be larger than the suction pipe. The purpose of the lines is to keep the losses to a minimum. This is done to make sure there is enough Net Positive Suction Head available to meet the requirements of the pump.

Can we use concentric reducer in pump suction?

Concentric reducer is recommended for vertical inlet (suction) piping or horizontal installations where there is no potential for air vapor accumulation. When the source of supply is above the pump, then the eccentric reducers must be placed with the flat side down.
