What is a Boiler Tube?

Boiler Tubes are metal tubes located inside of boilers that heat water in order to produce steam. There are two major types of tube boilers: water-tube boilers and fire-tube boilers.

In water-tube boilers, water circulates inside the tubes and is heated externally by hot gases generated by the furnace. With fire-tube boilers, hot gas passes through one or many tubes, which through thermal conduction, heats the water surrounding them. Boiler tubes are susceptible to certain damage mechanisms, including:

  • boiler feed water corrosion,
  • graphitization,
  • thermal fatigue, and
  • corrosion fatigue.

A boiler tube is a metal that is located inside boilers. These tubes are primarily designed to heat water in order to produce steam. There are two major types of boilers, namely water tube boilers, and fire tube boilers. They are designed to handle higher pressure and temperature fluids and gases in the system.

What is Heat exchanger tubes?

Heat exchanger tubes are designed to efficiently transfer heat between two fluids. Heat exchanger tubes are utilized in industries that require heat treatment processes. They can be produced in seamless or welded specifications. A U Tube has excellent thermal fatigue strength and is tolerant to corrosive affluents in different conditions.

Hot finished vs cold drawn Seamless boiler tubes

Hot finished seamless boiler tubes are processed at extreme temperatures, allowing them to have good forming properties. Cold Drawn Seamless boiler tubes are processed at room temperature soon after the hot rolling process. The cold drawn tubes are stronger in comparison to hot finished tubes, which have a lower processing time. Hot finished Seamless Steel Tubes and Pipes for Boilers are essentially normalized and free from any internal stress. Cold drawn boiler tubes have a precise finish.

What are Cold-finished Seamless Heat exchanger tubes?

Cold finished seamless heat exchanger tubes are devices that are produced in a cold state. These tubes are passed through hardened steel either or without a mandrel process. They have a superior surface finish that is technically precise. The versatile seamless tubes are harder and stronger and showcase excellent resistance to corrosive affluents. As the metal is produced at lower temperatures, tolerance against deformation is increased due to the work hardening process.
