The utility model discloses a kind of seamless steel pipe with high-lasting strength, comprise: steel pipe body, detachable Mg-32Li-2Al-0.5Ca alloy anticorrosion sheathed casing, resistance to compression fiber-filled flaggy, first valve and the second valve, described detachable Mg-32Li-2Al-0.5Ca alloy anticorrosion sheathed casing is arranged with in described steel pipe body, described resistance to compression fiber-filled flaggy is provided with between described steel pipe body and detachable Mg-32Li-2Al-0.5Ca alloy anticorrosion sheathed casing, the two ends of described steel pipe body are respectively arranged with the first described valve and the second valve.By the way, the utility model has high creep rupture strength, high oxidation resistance, and has good structure stability.
Description
Technical field
The utility model relates to seamless steel pipe field, particularly relates to a kind of seamless steel pipe with high-lasting strength.
Background technique
Along with domestic electrical industrial expansion, require also more and more higher to the thermal efficiency of boiler, the developing direction that the thermal efficiency is modern thermoelectricity plant is improved by the temperature and pressure improving steam, therefore domestic overcritical, the quantity of extra-supercritical unit also gets more and more, also improve constantly the requirement of material, researcher that is metallurgical and power industry is devoted to the exploitation of New Heat-Resistant Steel always.
High-pressure boiler tube is mainly used to manufacture high pressure and with carbon constructional quality steel, Alloy Constructional Steel and the stainless heat-resistance steel seamless steel tube of the steam boiler pipeline of upward pressure etc.But these boiler tubes work under being often in high temperature and high pressure, oxidation and corrosion also can occur pipe under the effect of high-temperature flue gas and water vapor.
Summary of the invention
The technical problem that the utility model mainly solves is to provide a kind of seamless steel pipe with high-lasting strength, has high creep rupture strength, high oxidation resistance, and has good structure stability.
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 with high-lasting strength, comprise: steel pipe body, detachable Mg-32Li-2Al-0.5Ca alloy anticorrosion sheathed casing, resistance to compression fiber-filled flaggy, first valve and the second valve, described detachable Mg-32Li-2Al-0.5Ca alloy anticorrosion sheathed casing is arranged with in described steel pipe body, described resistance to compression fiber-filled flaggy is provided with between described steel pipe body and detachable Mg-32Li-2Al-0.5Ca alloy anticorrosion sheathed casing, the two ends of described steel pipe body are respectively arranged with the first described valve and the second valve.
In the utility model preferred embodiment, described steel pipe body is nickel steel alloy steel pipe.
In the utility model preferred embodiment, the thickness of described resistance to compression fiber-filled flaggy is less than the thickness of described steel pipe body.
In the utility model preferred embodiment, described detachable Mg-32Li-2Al-0.5Ca alloy anticorrosion sheathed casing is fixed by snap on steel pipe body.
The beneficial effects of the utility model are: the utility model is provided with detachable Mg-32Li-2Al-0.5Ca alloy anticorrosion sheathed casing and resistance to compression fiber-filled flaggy, has high creep rupture strength, high oxidation resistance, and has good structure stability.
