Abstract
The invention discloses a seamless steel tube for a boiler. The seamless steel tube comprises an inner tube body and an outer tube body, wherein multiple supporting convex ribs are arranged on the inner tube body; the outer tube body is connected onto the other ends of the supporting convex ribs; multiple radiating fins are arranged on the outer tube body; multiple inner cavities are formed by the outer tube body, the supporting convex ribs and the inner tube body; polyurethane insulation coatings are arranged in the inner cavities. Through the manner, the seamless steel tube has an excellent heat preservation effect and is long in service life and simple in structure.
Description
Technical field
The present invention relates to seamless steel pipe field, particularly relate to a kind of boiler seamless steel pipe.
Background technique
In known technical field, boiler seamless steel pipe, it is high-pressure boiler tube, the a kind of of boiler tube, there is high strength, high anti-oxidation corrosivity and good stability, its purposes is mainly used for manufacturing various superheater tubes of working under superhigh temperature ultra-high voltage environment, boiling water tube, overheated steam pipe etc., in daily use, need to guarantee that temperature does not run off, improve the energy conversion efficiency of fuel, and existing high-pressure autoclave seamless steel pipe is not all taked Insulation specially, or just take common coating, can not play good heat insulation effect.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of boiler seamless steel pipe, can have good heat insulation effect, and long service life is simple in structure.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: a kind of boiler seamless steel pipe is provided, comprise: interior tube body and outer tube body, on described interior tube body, be provided with the prominent rib of a plurality of supports, described outer tube body is connected on the other end that supports prominent rib, on described outer tube body, be provided with a plurality of radiating fins, described outer tube body, the prominent rib of support and interior tube body form a plurality of inner chambers, are provided with polyurethane insulation coating in inner chamber body.
In a preferred embodiment of the present invention, the quantity of the prominent rib of described support is at least 2, is even interval and arranges between the prominent rib of described support.
In a preferred embodiment of the present invention, described radiating fin passes outer tube body, and contacts with polyurethane insulation coating.
In a preferred embodiment of the present invention, described interior tube body, outer tube body, the prominent rib of a plurality of support and a plurality of radiating fin are all formed in one.
In a preferred embodiment of the present invention, on described interior tube body and outer tube body, be coated with anticorrosive coat and pickling layer.
The invention has the beneficial effects as follows: boiler seamless steel pipe of the present invention, can there is good heat insulation effect, long service life, simple in structure.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the embodiment of the present invention, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also according to these accompanying drawings, obtain other accompanying drawing, wherein:
Fig. 1 is the structural representation of seamless steel pipe one preferred embodiment for boiler of the present invention;
In accompanying drawing, the mark of each parts is as follows: 1, interior tube body, 2, outer tube body, 3, support prominent rib, 4, radiating fin, 5, polyurethane insulation coating.
Embodiment
Below the technological scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Embodiment based in the present invention, those of ordinary skills, not making all other embodiments that obtain under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, a kind of boiler seamless steel pipe, comprise: interior tube body 1 and outer tube body 2, on described interior tube body 1, be provided with the prominent rib 3 of a plurality of supports, described outer tube body 2 is connected on the other end that supports prominent rib 3, on described outer tube body 1, be provided with a plurality of radiating fins 4, described outer tube body 1, the prominent rib 3 of support and interior tube body 2 form a plurality of inner chambers, are provided with polyurethane insulation coating 5 in inner chamber body.
In addition, the quantity of the prominent rib 3 of described support is at least 2, is even interval and arranges between the prominent rib 3 of described support.
In addition, described radiating fin 4 passes outer tube body 2, and contacts with polyurethane insulation coating 5, and radiating fin prevents polyurethane insulation coating over hot melting.
In addition, described interior tube body 1, outer tube body 2, the prominent rib 3 of a plurality of support and a plurality of radiating fin 4 are all formed in one.
In addition, on described interior tube body 1 and outer tube body 2, be coated with anticorrosive coat and pickling layer.
Be different from prior art, boiler seamless steel pipe of the present invention, can have good heat insulation effect, and long service life is simple in structure.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes specification of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
