High pressure alloy tube are mainly used to manufacture high-quality carbon structural steel, alloy structural steel and stainless heat-resistant steel seamless steel pipes for steam boiler pipes with high pressure and above pressure. These boiler pipes work under high temperature and high pressure. The pipe will also be oxidized and corroded under the action of high-temperature flue gas and water vapor, so the steel pipe is required to have high durable strength, high oxidation resistance, and good structural stability.

The main production process of High pressure alloy tube:

Tube blank and blank heating, perforation of tube blank, extension of steel pipe.

High pressure alloy tube use

High pressure alloy tube for low and medium pressure boilers (working pressure generally not greater than 5.88Mpa and working temperature below 450°C); for high-pressure boilers (working pressure generally above 9.8Mpa and working temperature between 450°C and 650°C) ) heating surface pipes; economizers, superheaters, reheaters, petrochemical industry pipes, etc.
