Specification
Boiler steel pipe refers to a steel product with both ends open and having a hollow section. The length of the seamless boiler tube is relatively large compared to its surroundings. The specifications of the steel pipe are external dimensions (such as outer diameter or side length) and The wall thickness indicates a wide range of sizes, from capillary tubes with very small diameters to large-diameter tubes with diameters of several meters. Boiler steel tubes can be used in pipelines, thermal equipment, machinery industries, petroleum geology exploration, vessels, chemical industry and special applications.
Types:
General use/ medium-pressure boiler tubes, High-pressure boiler tubes
Characteristics:
Due to the high pressure application, only seamless pipes and ERW get used as boiler products.
Boiler pies are available in carbon steel, alloy, and stainless steel options.
The Outer Diameter of boiler pipes varies from 6 mm to 1250 mm.
Boiler pipes have a low thickness ranging from 1 mm to 50 mm.
Application:
Steam Boilers, Fossil Fuel Plants, Heat Exchangers, Electric Power Plants, Cogeneration Facilities, Air Preheater Unit, Waste Heat Plants, Power Generation, Economiser etc.

Process
However, high pressure boiler tubes are processed further to improve their corrosion resistance, toughness, and hardness. These pipes go through the following extra process compared to general boiler pipes/ medium-pressure boiler pipes.
Quenching- this process refers to the practice of instant cooling where heated pipes get dipped into water and oil for cooling. Quenching improves steel hardness as the pipes must adjust to the quick changes in surface temperature.
Tempering rids the pipe of the brittleness caused by quenching.
In annealing, the steel is heated to a specific temperature and left to cool slowly in lime. this process helps get rid of the pie's internal stress.
