Abstract

The present invention relates to a kind of seamless pipe structure, including inner tube, the outside of said inner tube is provided with outer tube, and the middle part of said inner tube is formed with reach through hole, and the internal face of said inner tube is coated with protecting film.Present configuration is compact, reasonable, easily manufactured, by the effect of the inside face coating protective film in inner tube, can be greatly improved the intensity of pipe fitting; and mechanical property, at the same time it can also be reduce design wall thickness; weight saving 20%, price is more intended to low by 40% 60%, has an obvious economy.

Description

Seamless pipe structure
Technical field
The present invention relates to pipe fitting and produce equipment technical field, especially a kind of seamless pipe structure.
Background technology
At present, in the modernization commercial production such as oil, chemical industry, water process, at pipe conveying fluid and there is corrosion-resistant requirement Occasion, all use stainless steel material.But stainless price is more much higher than carbon steel, and stainless surrender is slightly than carbon Steel low, therefore under the conditions of identical pressure environment, wanting of stainless amount ratio carbon steel is many, thus considerably increases work The cost of journey.In the urgent need to a kind of corrosion-resistant, high intensity, cheap novel pipeline, critical material.Producing liner at present Stainless steel composite seamless pipe first carries out fracture with liner two-phase stainless steel composite steel pipe, carries out crucial production the most again, owing to making The length of liner two-phase stainless steel composite steel pipe at about 6m, the combination between the rustless steel of carbon steel pipes and liner when it produces Intensity and uniformity are poor, therefore bag, peeling are easily occurring with its production tubing products.
Summary of the invention
The applicant is for the shortcoming in above-mentioned existing production technology, it is provided that a kind of seamless pipe structure rational in infrastructure, So that its simple in construction, bag, the phenomenon peeled off are not had.
The technical solution adopted in the present invention is as follows:
A kind of seamless pipe structure, including inner tube, the outside of said inner tube is provided with outer tube, and the middle part of said inner tube is formed wears Through hole, the internal face of said inner tube is coated with protecting film.
Beneficial effects of the present invention is as follows:
Present configuration is compact, reasonable, easily manufactured, by the effect of the inside face coating protective film in inner tube, and can be significantly Improving the intensity of pipe fitting, and mechanical property, at the same time it can also be reduce design wall thickness, weight saving 20%, price is more intended to Low 40%-60%, has obvious economy.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Wherein: 1, outer tube;2, inner tube;3, protecting film;4, reach through hole.
Detailed description of the invention
Below in conjunction with the accompanying drawings, the detailed description of the invention of the present invention is described.
As it is shown in figure 1, the seamless pipe structure of the present embodiment, including inner tube 2, the outside of inner tube 2 is provided with outer tube 1, interior The middle part of pipe 2 is formed with reach through hole 4, and the internal face of inner tube 2 is coated with protecting film 3.
In actual manufacture process, complete as follows:
The first step: preparing raw material, one section of carbon steel seamless steel pipe, as inner tube 2;
Second step: processing carbon steel seamless steel pipe interior surface so that it is the dimensional accuracy of inner surface reaches IT8 level;Carbon steel seamless steel pipe The cylindricity of form tolerance less than 0.2mm, roughness is 3.2um;
3rd step: at the inside face coating protective film 3 of inner tube 2, protecting film 3 uses nano material;
4th step: the carbon steel seamless steel pipe outer surface that cleaning processes so that it is outer surface is without greasy dirt, dust;
5th step: be nested with one layer of outer tube 1 at outer surface
6th step: the multiple tube worked good is shaped processing, obtains the finished product pipe fitting of required size and dimension, add Hot temperature is 900 DEG C-1000 DEG C.
Above description is explanation of the invention, is not the restriction to invention, and limited range of the present invention sees right Requirement, within protection scope of the present invention, can make any type of amendment.
