Description
Product Overview
Boiler tubing is an essential component designed to withstand extreme high pressure and high temperature. They are extensively utilized in Steam Boilers, Power Generation, Fossil Fuel Plants, Electric Power Plants, Industrial Processing Plants, and Cogeneration Facilities.
Working Principles
- Fire Tube Boiler: A type of boiler in which hot gas passes from the fire through one or more pipes that pass through a sealed water container. The heat of the gas is transferred through the wall of the tube through heat conduction, heating the water and eventually generating steam. Fire tube boilers are the third of the four historical types of boilers.
- Water Tube Boiler: A type of boiler in which water circulates in tubes heated externally by the fire. The fuel is burned in the furnace to produce hot gas, which heats the water in the steam generation tube. In high-pressure water tube boilers, the hot water rises into the steam drum, where saturated steam is drawn away from the top.

Manufacturing Process
Our seamless boiler tubes undergo rigorous metallurgical and mechanical processes, passing through stages such as Blast Furnace/Electric Furnace, Continuous Casting, Blooming, Piercing, Cold Reducing/Drawing, Annealing, and Non-destructive Testing to ensure structural integrity and zero defects.
Packing & Delivery
We provide professional and secure packaging solutions to prevent corrosion and mechanical damage during transit. Boiler tubes are typically packed in hexagonal bundles bound with steel strips, or safely enclosed in sturdy wooden boxes for export shipments.
