Description
Technical field
The utility model is related to pipe technology field, specifically a kind of composite pipe.
Background technology
Existing composite bimetal pipe outer tube is cheap carbon steel tubing or low alloy steel, and wall thickness is larger, mainly
Bear external force or internal pressure；Inner tube uses expensive but excellent corrosion resistance stainless steel or nickel-base alloy or titanium or titanium alloy etc.
Resistant material, wall thickness is smaller, mainly serves corrosion resistant.The outer tube of composite bimetal pipe ensures in addition to corrosion resistance
Every object performance index, inner tube ensure corrosion resistance index, ensure all technical on the premise of, reach significantly
Spending reduces the purpose of cost, but traditional composite bimetal pipe, when bearing excessive external pressure, can be applied directly to inner tube, and
Inner tube is also by the pressure of pumped (conveying) medium so that inner tube easily causes damage, and composite pipe is connected not in recombination process
It is enough close, easily come off, multiple tube entirety discontinuity easily causes waste and needs often to change.
Therefore, to overcome the shortcomings of that above-mentioned technology is designed a simple in construction, combined strength bination is good, reduces inner tube and damages
It is bad, reduce a kind of composite pipe of product cost, exactly inventor's problem to be solved.
Utility model content
In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of composite pipe, and its is simple in construction, is combined
Intensity is good, reduces inner tube and damages, reduces product cost.
The utility model solves the technical scheme that its technical problem used：A kind of composite pipe, it includes basic unit
Pipe, internal lining pipe, melting layer, the melting layer are arranged between basic unit's pipe and internal lining pipe, and the internal lining pipe is stainless steel tube, described
Basic unit's pipe is carbon steel material, and outer wall and the basic unit's inside pipe wall of the internal lining pipe are provided with lug boss and concave part, the internal lining pipe
The lug boss of outer wall is connected with the concave part of basic unit's inside pipe wall, concave part and the basic unit's inside pipe wall of the liner pipe outer wall
Raised portion fits are connected.
Further, the lug boss is hemispherical with concave part.
The beneficial effects of the utility model are：
1st, the utility model is simple in construction, and inner tube is coordinated with outer tube by the way that bumps are alternate, and bond strength is good, by molten
Melting layer is connected, and be reduce further and is difficult to loosen between its joint gap, inner and outer pipes, and uniform force can effectively reduce inner tube damage
It is bad, reduce product cost.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Description of reference numerals：1- basic units manage；2- melting layers；3- internal lining pipes.
Embodiment
With reference to specific embodiment, the utility model is expanded on further, it should be appreciated that these embodiments are merely to illustrate this
Utility model rather than limitation scope of the present utility model.In addition, it is to be understood that reading the content of the utility model instruction
Afterwards, those skilled in the art can make various changes or modifications to the utility model, and these equivalent form of values also fall within application
Appended claims limited range.
It is the utility model structural representation referring to Fig. 1, a kind of composite pipe of the structure includes basic unit's pipe 1, internal lining pipe
3rd, melting layer 2, melting layer 2 is arranged between basic unit's pipe 1 and internal lining pipe 3, and internal lining pipe 3 is stainless steel tube, and basic unit's pipe 1 is carbon steel material
Matter, outer wall and the inwall of basic unit's pipe 1 of internal lining pipe 3 are provided with lug boss and concave part, and lug boss and the basic unit of the outer wall of internal lining pipe 3 manage
The concave part of 1 inwall is connected, and the concave part of the outer wall of internal lining pipe 3 is connected with the raised portion fits of the inwall of basic unit pipe 1, lug boss
It is hemispherical with concave part.
The utility model is simple in construction, and inner tube is coordinated with outer tube by the way that bumps are alternate, and bond strength is good, passes through melting
Layer connection, reduce further and be difficult to loosen between its joint gap, inner and outer pipes, and uniform force can effectively reduce inner tube damage,
Reduce product cost.
