Abstract
The utility model belongs to stainless steel tubes, and particularly relates to a novel stainless steel tube. The novel stainless steel tube is characterized in that an inner tube body and an outer tube body are included, the outer tube body is sleeved on the inner tube body, a sealing cavity is formed between the inner tube body and the outer tube body, and the gap between the outer tube body and the inner tube body is 2mm to 1mm. The novel stainless steel tube has the effect of internal thermal insulation, meets the insulation requirement of people, and meanwhile overcomes the defects that a traditional insulating layer is high in later period maintenance cost and troublesome in maintenance.
Description
Technical field
The utility model belongs to stainless-steel pipe, particularly a kind of stainless-steel pipe.
Background technique
Present stainless-steel pipe more and more is used to various pipe-line constructions, some pipeline needs certain insulation requirement, people are in order to reach the insulation requirement, and coat one deck thermal insulation layer on the surface of pipeline usually, but have the problem of several respects like this: thermal insulation layer exposes in air, be subjected to the corrosion of various factors in the air, after using a period of time, heat insulation effect descends, just the thermal insulation layer that need more renew, the time of cost is more, and cost is bigger.
The model utility content
The utility model has designed a kind of novel stainless steel steel pipe with interior heat insulation effect at the deficiencies in the prior art, satisfies the insulation requirement that people propose, and has also overcome the defective that traditional thermal insulation layer later maintenance is high and maintenance bothers simultaneously.
The utility model is achieved through the following technical solutions:
Novel stainless steel steel pipe is characterized in that: comprise interior tube body and outer tube body, described outer tube body is sheathed on the interior tube body, and forms the cavity of a sealing between interior tube body and the outer tube body, and the gap between outer tube body and the interior tube body is between 2mm～1cm.
Be filled with thermal-protective material in the described cavity, the thermal-protective material of setting can further improve the heat insulation and preservation effect of novel stainless steel steel pipe.
The surface of described outer tube body is provided with the nitriding layer that improves surface hardness, and the nitriding layer of setting can improve surface hardness, has higher intensity and corrosion resistance.
The utlity model has following advantage:
The utility model is at the deficiencies in the prior art, designed and a kind ofly constituted by interior tube body and outer tube body, and be provided with the novel stainless steel steel pipe of seal chamber between interior tube body and the outer tube body, the seal chamber that arranges can effectively improve the heat insulation and preservation effect of stainless-steel pipe, in order further to improve heat insulation and preservation effect, we can also be in cavity fill insulant material, the utility model has been realized a kind of novel stainless steel steel pipe with heat insulation and preservation effect, has overcome the defective that traditional thermal insulation layer later period maintenance is high and maintenance bothers.
Description of drawings
By the detailed description below in conjunction with accompanying drawing, aforesaid purpose, the feature and advantage with other of the utility model will become apparent.Wherein:
Fig. 1 is mode of execution one structural representation;
Fig. 2 is mode of execution two structural representations;
1 is outer tube body among the figure, and 2 is cavity, and 3 is interior tube body, and 4 is thermal-protective material.
Embodiment
Mode of execution one
Novel stainless steel steel pipe, it is characterized in that: comprise interior tube body 3 and outer tube body 1, described outer tube body 3 is sheathed on the interior tube body 1, and form the cavity 2 of a sealing between interior tube body 3 and the outer tube body 1, gap between outer tube body and the interior tube body is between 2mm～1cm, be filled with air in the cavity 2, air has the low characteristics of heat conduction efficiency, and the described novel stainless steel of present embodiment steel pipe has certain heat insulation and preservation effect.
The surface of described outer tube body is provided with the nitriding layer that improves surface hardness, and the nitriding layer of setting can improve surface hardness, has higher intensity and corrosion resistance.
Mode of execution two
Novel stainless steel steel pipe, it is characterized in that: comprise interior tube body 3 and outer tube body 1, described outer tube body 3 is sheathed on the interior tube body 1, and forms the cavity 2 of a sealing between interior tube body 3 and the outer tube body 1, and the gap between outer tube body 1 and the interior tube body 3 is between 2mm～1cm.
Be filled with thermal-protective material 4 in the described cavity 2, the thermal-protective material of setting can further improve the heat insulation and preservation effect of novel stainless steel steel pipe.
The surface of described outer tube body is provided with the nitriding layer that improves surface hardness, and the nitriding layer of setting can improve surface hardness, has higher intensity and corrosion resistance.
The utlity model has following advantage:
The utility model is at the deficiencies in the prior art, designed and a kind ofly constituted by interior tube body and outer tube body, and be provided with the novel stainless steel steel pipe of seal chamber between interior tube body and the outer tube body, the seal chamber that arranges can effectively improve the heat insulation and preservation effect of stainless-steel pipe, in order further to improve heat insulation and preservation effect, we can also be in cavity fill insulant material, the utility model has been realized a kind of novel stainless steel steel pipe with heat insulation and preservation effect, has overcome the defective that traditional thermal insulation layer later period maintenance is high and maintenance bothers.
The utility model is not limited to described embodiment; those skilled in the art is not breaking away from spirit of the present utility model namely openly in the scope; still can do some corrections or change, so rights protection scope of the present utility model is as the criterion with claims restricted portion.
