Abstract
A titanium and steel seamless composite pipe is characterized in that the titanium and steel seamless composite pipe is divided into an inner layer and an outer layer, wherein the inner layer is a titanium seamless pipe, and the outer layer is a steel seamless pipe; the outer layer is a stainless steel seamless pipe; the thickness of the outer layer is larger than or equal to that of the inner layer; and the inner layer and the outer layer are formed through hot press molding and are round. The inner layer is the titanium seamless pipe with high corrosion resistance, and the outer layer is the steel seamless pipe with high strength, so that the requirements for the corrosion resistance and the high strength are met, and the production cost is reduced.
Description
Technical field
The present invention relates to a kind of titanium, steel seamless multiple tube, belong to mechanical pipe fitting field.
Background technique
In chemical industry, medicine and other fields, often use corrosion protection tubing, titanium seamless tubes is exactly a kind of corrosion protection tubing commonly used, but titanium seamless tubes is often expensive, increase cost of production, and its intensity is low, can not meet requirement of strength.So the titanium alloy weldless tube has just been arranged, adopt the titanium alloy weldless tube, although tubing intensity is strengthened to some extent, but corrosion protection intensity also reduces simultaneously.Therefore, be necessary to invent a kind of titanium, steel seamless multiple tube that had not only met requirement for anticorrosion but also met requirement of strength.
Summary of the invention
For the deficiencies in the prior art, the purpose of this invention is to provide a kind of meet simultaneously anticorrosion and titanium, steel seamless multiple tube requirement of strength.
For achieving the above object, the present invention realizes by following technological means:
A kind of titanium, steel seamless multiple tube is characterized in that: described titanium, steel seamless multiple tube are divided into inside and outside two-layer, and internal layer is titanium seamless tubes, and skin is the steel weldless tube.
Preferably, described skin is stainless steel seamless pipe;
Preferably, described outer layer thickness is greater than or equal to internal layer thickness;
Preferably, described internal layer, outer by hot-forming;
Preferably, described internal layer, skin are circular.
The invention has the beneficial effects as follows: by internal layer, be high erosion-resisting titanium seamless tubes, skin is high-intensity steel weldless tube, has met anticorrosive, high-intensity requirement, has reduced cost of production.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The implication of drawing reference numeral is as follows:
1 skin, 2 internal layers.
Embodiment
Below in conjunction with Figure of description, the present invention is further illustrated.
As shown in Figure 1, a kind of titanium, steel seamless multiple tube is characterized in that: described titanium, steel seamless multiple tube are divided into inside and outside two-layer, and internal layer 2 is titanium seamless tubes, and outer 1 is the steel weldless tube, has met anticorrosive, high-intensity requirement.
Preferably, described outer 1 is stainless steel seamless pipe, when meeting requirement of strength, makes the tubing outside also have erosion-resisting function;
Preferably, described outer 1 thickness is greater than or equal to internal layer 2 thickness, can select according to different anticorrosive and requirement of strength;
Preferably, described internal layer 2, outer 1, by hot-forming, closely links together internal and external layer, gains in strength;
Preferably, described internal layer 2, outer 1 is circular.
Above demonstration and described basic principle of the present invention, major character and advantage.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
