Abstract
The utility model relates to stainless steel pipes for a boiler heat exchanger. Each stainless steel pipe comprises a hollow steel pipe body, an inner wall arranged in the steel pipe body and an outer wall arranged outside the steel pipe body, wherein the section of each steel pipe body is in a circular structure, diameters of the steel pipe bodies are the same, the inner walls are smooth, coatings are covered on the outer walls, the coatings are acrylic resin paint with calcium carbonate particles as filler, and each steel pipe body is made of 304L stainless steel materials. The stainless steel pipes for the boiler heat exchanger are simple in structure, low in cost and recyclable, increases the flow speed of fluids due to the fact that the inner walls are polished, improves corrosion-resistant property of the steel pipes due to the fact that the coatings are added on the outer walls, prolongs service life of the boiler heat exchanger, and is easy to popularize and use.
Description
Technical field
The utility model relates to a kind of alloy steel seamless steel tube, especially a kind of boiler heat exchanger stainless-steel seamless pipe.
Background technology
Boiler heat exchanger is the High Efficiency Thermal switching equipment in the modern project application, be widely used, occupy aborning critical role, the employed stainless-steel seamless pipe of boiler heat exchanger requires to have high creep rupture strength at high temperatures and high high temperature resistance steam corrosion ability, requires to have again enough toughness, machinability and weldability.Because of its special environment for use requirement, be used in the market the stainless-steel seamless pipe dependence on import of boiler heat exchanger, the production cycle is long, and cost is high, has greatly restricted China's expanding economy.
The utility model content
The technical problems to be solved in the utility model is: in order to solve the problem that proposes in the above-mentioned background technology, the utility model provides a kind of boiler heat exchanger stainless-steel seamless pipe, it is simple in structure, cheap for manufacturing cost, can bear high pressure, corrosion resistance, and tube wall the condensation globule can not occur when difference variation is larger.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of boiler heat exchanger stainless-steel seamless pipe, the steel pipe body that comprises hollow, be arranged at the intrinsic inwall of steel pipe and be arranged at this external outer wall of steel pipe, the cross section of steel pipe body is circular configuration, the diameter of steel pipe body is identical, inwall is shiny surface, is coated with coating on the outer wall.
Further, coating is with the esters of acrylic acid coating of particulate calcium carbonate as filler.
Further, the steel pipe body is that the 304L stainless steel material is made.
The beneficial effects of the utility model: boiler heat exchanger stainless-steel seamless pipe of the present utility model, simple in structure, with low cost, and recyclable recycling, feature of environmental protection new product belonged to, inwall is polishing, accelerated the flowing velocity of fluid, outer wall has increased coating, has improved the corrosion resistance of stainless-steel seamless pipe, prolong heat exchanger service life, be easy to apply.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model.
Among the figure 1, the steel pipe body, 2, inwall, 3, outer wall, 4, coating.
The specific embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of boiler heat exchanger stainless-steel seamless pipe as shown in Figure 1, the steel pipe body 1 that comprises hollow, be arranged at inwall 2 and the outer wall 3 that is arranged at outside the steel pipe body 1 in the steel pipe body 1, the cross section of steel pipe body 1 is circular configuration, the diameter of steel pipe body 1 is identical, inwall 2 is shiny surface, accelerated the flowing velocity of tube fluid, be coated with coating 4 on the outer wall 3, coating 4 is with the esters of acrylic acid coating of particulate calcium carbonate as filler, has water imbibition and water proofing property, the water droplet of outer wall when having reduced condensation, improved the corrosion resistance of steel pipe, steel pipe body 1 is made for the 304L stainless steel material.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
