Description
Technical field
The utility model relates to seamless steel pipe field, particularly relates to a kind of seamless steel pipe for steam line.
Background technique
Pressure piping is steam line particularly, and interior media mostly is the hot water of boiling, and because the long wearing and tearing of year number used make trommel, and the pressure of pipeline reaches the ability to bear of pipe, then cause the explosive accident of pipeline.The pipe of steam is at interval of after use 3-5, and the pressure-bearing experiment that testing tube arrives is carried out in suggestion.The corrosion of steam line easily occurs in the bending of pipeline, position of turning round, and has steam flow into and flow to vicissitudinous position in streamlined pipeline section.The lower surface of buried pipeline outside easily produces corrosion.
But the resistance to high temperature at present for the seamless steel pipe of steam line is bad, can not sharply change by Applicable temperature, mechanical strength and decay resistance await improving.
Summary of the invention
The technical problem that the utility model mainly solves is to provide a kind of seamless steel pipe for steam line, and resistance to high temperature is good, can sharply change by Applicable temperature, mechanical strength and excellent anti-corrosion performance.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: provide a kind of seamless steel pipe for steam line, comprising: steel pipe body, Mo
f/ TiAl composite layer, diamond/silicon carbide composite layer, 3Y-ZrO
