Abstract
The utility model relates to a corrosion resistant stainless steel composite pipe which is characterized by being compounded by a stainless steel layer and a carbon steel layer in a metallurgy mode, and the stainless steel layer is located on the outer surface of the carbon steel layer. The corrosion resistant stainless steel composite pipe has the advantages of being scientific and reasonable in structural design, strong in corrosion resistant capacity, long in service life, capable of reducing loss, low in cost, and easy to realize, and has high innovativeness.
Description
Technical field
The utility model relates to a kind of line pipe, particularly a kind of erosion-resisting stainless steel composite pipe.
Background technique
Steel pipe often is used to carry fluid and the powdery solids such as water, coal gas, rock gas, oil, powder as a kind of line pipe.Because it is underground that pipeline will be layed in mostly, be subjected to the different of the difference of each department soil property and weather, common conveying steel pipe is layed in for a long time and undergroundly the phenomenon of corrosion can occurs, thereby has shortened the working life of pipeline, cause leak, the losses such as gas leakage, leakage of oil.If replace with Stainless Steel Tube fully, can can't realize because produce stainless steel needed raw material " nickel " high cost.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of and have that design science is reasonable, anti-corrosion capacity is strong, long service life, can reduce the loss, cost is low, the stainless steel composite pipe that is easy to realize.
The utility model solves its technical problem and takes following technological scheme to realize:
A kind of erosion-resisting stainless steel composite pipe is characterized in that: by stainless steel lining, the metallurgical integrator of carbon steel layer, described stainless steel lining is positioned on the outer surface of carbon steel layer.
Advantage of the present utility model and good effect are:
1. this erosion-resisting stainless steel composite pipe, by stainless steel lining, the metallurgical one that forms of carbon steel layer, effective adhesive strength of two kinds of metal layers reaches 210MPa, by special welding procedure, stainless steel clad plate is processed into vertical masonry joint stainless steel composite pipe, spiral stainless steel composite pipe.This composite pipe is because the superior function of stainless steel self, realized that the anti-corrosion capacity of homogeneous tube is strong, long service life, the advantage that can reduce the loss.And being combined in of stainless steel and carbon steel also reduced cost of production when having realized various superiority, makes the large size of this composite pipe throw in feasible that use becomes.
2. the utility model scientific structure design is reasonable, have advantages of that anti-corrosion capacity is strong, long service life, can reduce the loss, cost is low, be easy to realize, is a kind of stainless steel composite pipe with higher innovation.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Description of reference numerals:
1-stainless steel lining, 2-carbon steel layer.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing, by specific embodiment.Following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of erosion-resisting stainless steel composite pipe, its innovation is: by stainless steel lining 1, carbon steel layer 2 metallurgical integrator, described stainless steel lining is positioned on the outer surface of carbon steel layer.
This erosion-resisting stainless steel composite pipe, by stainless steel lining, the metallurgical one that forms of carbon steel layer, effective adhesive strength of two kinds of metal layers reaches 210MPa, by special welding procedure, stainless steel clad plate is processed into vertical masonry joint stainless steel composite pipe, spiral stainless steel composite pipe.This composite pipe is because the superior function of stainless steel self, realized that the anti-corrosion capacity of homogeneous tube is strong, long service life, the advantage that can reduce the loss.And being combined in of stainless steel and carbon steel also reduced cost of production when having realized various superiority, makes the large size of this composite pipe throw in feasible that use becomes.
Although disclose for the purpose of illustration embodiment of the present utility model and accompanying drawing, but it will be appreciated by those skilled in the art that: in the spirit and scope that do not break away from the utility model and claims, various replacements, variation and modification all are possible, therefore, scope of the present utility model is not limited to embodiment and the disclosed content of accompanying drawing.
