What is Retubing of heat exchanger?
What is Retubing of heat exchanger?
Click image to enlarge. Heat exchanger tubes are constantly expanding and contracting as they heat up and cool down during normal operations. Depending on the application, salt water scale, calcium, lyme and other contaminants can compound the problem, leading to even faster deterioration.

How is heat exchanger design calculated?
4.0 – HEAT EXCHANGERS CALCULATIONS:
- The main basic Heat Exchanger equation is: Q = U x A x ΔTm =
- The log mean temperature difference ΔTm is: ΔTm =
- (T1 – t2) – (T2 – t1) = °F.
- T1 = Inlet tube side fluid temperature; t2 = Outlet shell side fluid temperature;
- ln (T1 – t2) (T2 – t1)
How much are industrial heat exchangers?
A heat exchanger can cost anywhere from $300 to $3,000 depending on the size of the furnace and the brand. Commercial varieties range all the way up to $10,000.
What is the meaning of Retubing?
noun. The procedure of providing a new tube or tubes.
How heat exchangers are manufactured?
In a process of manufacturing a heat exchanger, the steps comprising flattening the opposite sides of a heat exchanger tube to form flattened walls at said opposite sides, positioning a heat exchanger fin in contact with said flattened walls of said tube, bonding said tube and said fin together at the contact …
Should I replace heat exchanger?
There are only two options if a Heat Exchanger is bad: Replace the heat exchanger or replace the furnace. If the heat exchanger is under warranty, this option is a good way to go unless it is unavailable in the time frame needed, which can be immediate in cold weather.
Why use corrugated tubes in heat exchangers?
Why use corrugated tubes in heat exchangers? Increased efficiency. When a fluid passes through a tube, several things affect the way in which it moves, such as pressure, the nature of the fluid (how viscous it is), Smaller footprint. Longer running times. Easier maintenance and cleaning.
Are spacers necessary in heat exchanger?
The spacers repel water , and the vapor condensation in the passages in the heat exchanger can be exhausted outside the heat exchanger by wind pressure without staying on the spot in the passages, offering an advantage in that an increase in pressure loss in the heat exchanger due to the vapor condensation is prevented.
What is the purpose of the heat exchanger?
The general function of a heat exchanger is to transfer heat from one fluid to another. The basic component of a heat exchanger can be viewed as a tube with one fluid running through it and another fluid flowing by on the outside.
