Abstract
The utility model discloses a stainless steel composite pipe, which comprises a base pipe and a stainless steel pipe which is arranged in the base pipe. A diameter of the stainless steel composite pipe is larger than 500mm, and the base pipe is a seamless iron pipe. According to the stainless steel composite pipe, the diameter is larger than 500mm, the stainless steel composite pipe has a large diameter and has same performances of corrosion resistance, bending resistance and pressure resistance with a stainless steel seamless pipe, the diameter is large, the cost is low, and an application scope is wide.
Description
Technical field
The utility model belongs to the metal pipe technical field, is specifically related to a kind of stainless steel composite pipe.
Background technique
Stainless Steel Tube is a kind of rectangular circular steel of hollow, because of its excellent corrosion resistant, wear-resisting, heat resistance and its glittering, luxurious surface, and is widely used in the daily life, as sewage treatment pipeline, road bridge protective railings, balustrade etc.But limit by China's Ni natural resources shortage, the stainless steel demand is dependence on import to a great extent, the price comparison costliness.
Stainless steel seamless pipe is a kind of rectangular steel that hollow section, periphery do not have seam that have.The wall thickness of this product is more thick, and it just more has Economy and practicability, and wall thickness is more thin, and its processing cost will significantly rise; The technology of this product determines its limitation performance, and general seamless steel pipe precision is low: wall unevenness is even, inside and outside low, the scale cost height of mass color brightness of pipe, and its detection and shaping must processed offline.Stainless steel seamless pipe adopts hot rolling, hot extrusion or cold-drawn (rolling) technology to make more, but the diameter of hot rolling (hot extrusion) steel pipe is 54～480mm; The diameter of cold-drawn (rolling) steel pipe is 6～200mm, so rare large-caliber stainless steel weldless tube on the market at present, even the large-caliber stainless steel weldless tube is arranged, it is also quite expensive, makes the selectivity of the high pressure occasion that must select weldless tube for use diminish.
For addressing the above problem, need provide a kind of bigbore, stainless steel composite pipe that performance is equal to stainless steel seamless pipe.
Summary of the invention
The utility model purpose provides a kind of stainless steel composite pipe, and corrosion-resistant, shock resistance, intensity height, bore is big, cost is low.
For achieving the above object, the technical solution adopted in the utility model is: a kind of stainless steel composite pipe comprises parent tube and is located at the interior Stainless Steel Tube of this parent tube that the bore of described stainless steel composite pipe is greater than 500mm.
In the technique scheme, described parent tube is seamless iron pipe.
Described parent tube is not limited to iron pipe, can also select seamless common steel tube or Coating Steel Pipe for use.
In the technique scheme, the bore of described parent tube is 500 ~ 1000mm.
Because technique scheme is used, the advantage that the utility model compared with prior art has is:
1. bore of the present utility model is the large-caliber stainless steel composite pipe greater than 500mm, has identical with stainless steel seamless pipe corrosion-resistant, bending resistance, compression resistance, and bore is big, cost is low, and using scope is wide.
Description of drawings
Fig. 1 is the utility model embodiment one sectional view;
Wherein: 1, parent tube; 2, Stainless Steel Tube.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment one: referring to shown in Figure 1, a kind of stainless steel composite pipe, comprise parent tube 1 and the Stainless Steel Tube of being located in this parent tube 12, the bore 800mm of described stainless steel composite pipe, be the large-caliber stainless steel composite pipe, have identical with stainless steel seamless pipe corrosion-resistant, bending resistance, compression resistance, bore is big, cost is low, and using scope is wide.
In the present embodiment, described parent tube 1 is seamless iron pipe.
The bore of described parent tube 1 is 806mm.
Embodiment two: a kind of stainless steel composite pipe, comprise parent tube and be located at the interior Stainless Steel Tube of this parent tube, the bore of described stainless steel composite pipe is 600mm, be the large-caliber stainless steel composite pipe, have identical with stainless steel seamless pipe corrosion-resistant, bending resistance, compression resistance, bore is big, cost is low, and using scope is wide.
In the present embodiment, described parent tube is seamless iron pipe.
The bore of described parent tube is 604mm.
The above is preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model
