Answer / kausik bhattacharyya

The basic difference is dictated by the application.
Tubes are meant for both heat and mass transfer.(Because of
this finishing is different and dimension tolerances are
more accurate.)
Pipes on the other hand ,are for mass transfer.

Answer / rakesh mittal

pipe is identified by Nominal Bore & THIKNESS is defined by
schedule where as tube is identified by OD & thickness by
gauge
one more difference is dictated by the application.

this finishing is different and dimension tolerances are

Pipes on the other hand ,are for mass transfer.

Answer / abdullah

pipe is identified by NB & THIKNESS is defined by
schedule.tube is identified by OD.....PIPE WHERE WE CAN
USE THERE PRESSURE IS MORE THAN 1bar...tube is use where
pressure is less than 1 bar...........

Answer / vasudev karve

Pipes are used for mass transfer eg- water pipes, steam pipes
On the other hand tubes are used for heat transfer eg -
superheater tubes, economiser tubes.
As per ASME section 2 part A the materials of tubes and
pipes are diferent. You can have pipes forged and rolled but
tubes are seamless. The tolerances on tubes are tighter as
compared to pipes so tubes are costly as compared to pipes.
Geometry wise there is no difference but differentiation is
based on the intended use.

Answer / magesh

If there is a heat transfer takes place, it is called as
tube. Normally in Boilers, we call as waterwall tubes which
are sorrounded in the furnace. Where as the Steam and Feed
Pipings we call them as Pipe, because there is no heat
transfer. It just carries steam to Turbine and water to
Boiler respectively.

Answer / nori vsn murthy

The fundamental difference between pipe and tube is:

Pipe is for mass transfer applications, whereas, tube is
for heat transfer applications.

Due to this fundamental difference, we generally call pipes
and tubes as: water pipes, steam pipes, slurry pipes,
boiler tubes, heat exchanger tubes, radiator tubes, etc.

Answer / santosh raikar

major difference is tube-heat transfer and mass transfer
pipe-only mass transfer, neglecting
small heat transfer due to the surroundings.

Answer / hussain. alsomali

The differences is the measurement.
Pipe you measure ID + wall thickness= The size
Tube you measure OD only = The size

Answer / ashish kumar

In short pipe is measured by inside diameter where as tubes are measured by outer diametre.

Answer / pravin

tube are indicated by NB nominal bore diameter and pipe
indicated by is id
