Abstract
The utility model relates to a metal tube, particularly to a multiple-layer composite tube of which the surface layer is a nonrust tube. The utility model aims to solve the problem that the existing metal tube and the existing composite tube have untight application and gaps, interlayers and delamination. A soldered composite tube comprises nonrust tubes (2, 3) and a parent tube (1) which are sheathed, wherein metallurgy link layers (4, 5) are arranged between the parent tube and the nonrust tubes. The nonrust tubes can be arranged in the parent tube or outside the parent tube. The nonrust tubes (2, 3) are stainless steel tubes or titanium alloy tubes; the wall thickness of the nonrust tubes is from 0.1 to 0.8mm. The parent tube (1) can be a carbon steel tube. The utility model is suitable for conveying high temperature corrosive fluid media and high voltage corrosive fluid media in the oilfield industry, the chemical industry, the medicine industry, the foodstuff industry, etc., and can also be widely used for the building industry, the decoration industry, the public facilities field, the furniture manufacturing industry, the car and ship manufacturing industry, etc.
Description
Technical field
The utility model relates to metal type pipe, and particularly the top layer is the multi-layered composite pipe of stainless pipe.
Background technique
Existing stainless steel composite pipe is made of the parent tube of carbon steel system and the stainless pipe that is linked in the basal body pipe top layer.The composite pipe of this structure has advantages such as structural strength height, the bearing capacity of carbon steel tubing be strong, and it is strong that its top layer pipe has an antirust ability, advantages such as good decorative property.Because composite pipe adopts mechanical composite algorithm to make usually, it is not tight to fit between parent tube and stainless pipe, has gap and delamination, produces mezzanine space.When at mezzanine space slag inclusion and dirt being arranged, slag inclusion and dirt can quicken the corrosion of composite metal pipe.When particularly composite pipe used in the environment that air, water and other Korrosionsmedium are arranged, air, water and Korrosionsmedium were easy to be penetrated in the mezzanine space of composite pipe, quickened the corrosion of composite pipe, shortened the working life of composite pipe.This in addition composite pipe is because the separation of interlayer or have the gap when composite pipe is carried out bending, is easy to generate wrinkle; During welding processing, be easy to generate quality problems such as sticking up the arch distortion near the weld seam, thereby the application area of composite pipe is restricted.
The model utility content
In view of above-mentioned, the purpose of this utility model is to provide a kind of parent tube and the stainless pipe brazed composited tube closely of fitting.
The utility model adopts between parent tube and stainless pipe with the two metallurgical tie layer of combining closely and realizes its purpose.
Brazed composited tube of the present utility model (referring to accompanying drawing), parent tube that is nested with (1) and stainless pipe (2,3) is characterized in that metallurgical tie layer (4,5) is arranged between parent tube and stainless pipe.
Above-mentioned stainless pipe (2) is in parent tube (1).
Above-mentioned stainless pipe (3) is outside parent tube (1).
Above-mentioned stainless pipe (2) is in parent tube (1), and stainless pipe (3) is outside parent tube (1).
Above-mentioned stainless pipe (2,3) is Stainless Steel Tube or titanium alloy tube, and the wall thickness of stainless pipe is 0.1～0.8mm.
Above-mentioned parent tube (1) can be a carbon steel tubing.
When making brazed composited tube of the present utility model, earlier with the applying pipe face of parent tube, stainless pipe plated solder copper respectively; Again parent tube and stainless pipe box are lumped together, carry out drawing with common tubulation drawing machine and expand and to close processing; Heat then, be incubated, the solder that makes fusion is filled the gap between seamless carbon steel parent tube and stainless pipe by capillarity and Wetting action, through cooling, makes the solder melting crystal again, forms the metallurgical tie layer of soldering, makes brazed composited tube.
Brazed composited tube of the present utility model and existing metal composite pipe are relatively, composite pipe of the present utility model adopts method for welding, between parent tube and stainless pipe, form the metallurgical metallurgical tie layer that merges, and, closely be fused into the composite pipe of entity tube wall with parent tube and two kinds of very big metal tubes of physical property difference of stainless pipe.Very close to each other between parent tube and stainless pipe, interlayer and delamination have good mechanical property, and good bandability can bear high temperature and 10Mpa pressure below 450 ℃, also has good high temperature resistant, decay resistance, and specious, ornamental good.
Brazed composited tube of the present utility model is applicable in the industries such as oil, chemical industry, medicine, food and carries high temperature, high pressure, active sulfur body medium.Also can be widely used in fields such as building industry, adnornment industry, urban operating mechanism, furniture manufacturing industry, car and boat manufacturing industry.
Below, the utility model is further described to use embodiment and accompanying drawing thereof again.
Description of drawings
Accompanying drawing is the cross-sectional configuration schematic representation of a kind of brazed composited tube of the present utility model.
