2. What is Boiler Steel Pipe? In-depth Product Analysis
Boiler steel pipe refers to specialty steel pipes designed for high- and low-pressure boiler systems. These pipes must withstand extreme conditions—high temperature, high pressure, and aggressive media—making rigorous quality, reliability, and safety essential.
Seamless boiler tubes are widely used due to their outstanding resistance to rupture, creep (slow deformation under high temp/stress), and corrosion.
