Abstract
The invention discloses a seamless steel tube for a boiler. The seamless steel tube comprises an outer tube, an inner tube, a supporting tube and a filling layer, wherein the outer tube and the inner tube are connected through the supporting tube; the supporting tube consists of three steel tubes; a regular tetrahedron framework structure is formed in a space; the vertex of the regular tetrahedron framework structure is connected with the outer tube, and the rest three points are connected with the inner tube; the filling layer is further arranged between the outer tube and the inner tube; and a thermal insulation material is filled in the filling layer. The seamless steel tube for the boiler disclosed by the invention is high in strength, good in thermal insulation property and long in service life.
Description
Technical field
The present invention relates to a kind of seamless steel pipe, particularly a kind of boiler seamless steel pipe.
Background technique
Industrial boiler is in high temperature and high pressure environment for a long time, and boiler tube, under the effect of high-temperature flue gas and water vapor, oxidation and corrosion easily occurs, and therefore requires that steel pipe has high creep rupture strength, oxidation resistance, and has good structure stability; And boiler is as a kind of thermal device, need good thermal insulation property, to prevent excess calories to scatter and disappear, reach the object of energy efficient.
Boiler seamless steel pipe is in the market generally individual layer pipeline, and intensity and thermal insulation property are all inadequate, need frequent maintenance and repair, even replace, consume a large amount of human and material resources, and the stoppage in transit of boiler can cause great economic loss.
Summary of the invention
The object of the invention is to overcome the defect existed in prior art, provide a kind of boiler seamless steel pipe, this seamless steel pipe intensity is high, has higher anti-pressure ability, and has good heat insulation effect.
For achieving the above object, design proposal of the present invention is as follows:
A kind of boiler seamless steel pipe, comprise outer tube, interior pipe, support tube and packed layer, outer tube is positioned at the outermost surface of seamless steel pipe, and interior pipe is positioned at the innermost layer of seamless steel pipe; Be connected by support tube between outer tube and interior pipe, support tube is made up of 3 steel pipes, and form a positive tetrahedron skeletal structure in space, its summit is connected with outer tube, and its excess-three point is connected with interior pipe; Support tube is evenly arranged in outer tube and interior pipe, arrange that quantity is determined according to the size of seamless steel pipe, but along the same profile meter of seamless steel pipe, quantity is no less than 4; Between outer tube and interior pipe, except support tube, remaining region is packed layer, is filled with thermal insulating material in packed layer.
More preferably, above-mentioned interior pipe internal surface is coated with anticorrosive coat, and outer tube outer surface is coated with thermal insulation layer, and in packed layer, thermal insulating material is rock wool.
Advantage of the present invention and beneficial effect are:
1) positive tetrahedron structure is stable structure the most, in the two-layer centre of seamless steel pipe, this structure is set, contribute to the intensity improving steel pipe, steel pipe is enable to bear larger pressure, and because interior pipe pressure is higher than outer pipe pressure, therefore on support tube, three summits are connected with interior pipe, and a summit is connected with outer tube, can balance the pressure difference between inner and outer pipes;
2) establish thermal insulation layer in the middle of seamless steel pipe, outer tube outer surface is coated with thermal insulation layer, effectively can prevent heat loss, reaches the object of energy efficient.

Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is further described.Following examples only for technological scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
The technological scheme that the present invention specifically implements is:
A kind of boiler seamless steel pipe, comprise outer tube 1, interior pipe 2, support tube 3 and packed layer 4, outer tube 1 is positioned at the outermost surface of seamless steel pipe, and interior pipe 2 is positioned at the innermost layer of seamless steel pipe; Be connected by support tube 3 between outer tube 1 and interior pipe 2, support tube 3 is made up of 3 steel pipes, and form a positive tetrahedron skeletal structure in space, its summit is connected with outer tube 1, and its excess-three point is connected with interior pipe 2; Support tube 3 is evenly arranged in outer tube 1 and interior pipe 2, arrange that quantity is determined according to the size of seamless steel pipe, but along the same profile meter of seamless steel pipe, quantity is no less than 4; Between outer tube 1 and interior pipe 2, except support tube 3, remaining region is packed layer 4, is filled with thermal insulating material in packed layer 4.
More preferably, above-mentioned interior pipe 2 internal surface is coated with anticorrosive coat, and outer tube 1 outer surface is coated with thermal insulation layer, and in packed layer 4, thermal insulating material is rock wool.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
