Abstract
The invention discloses a novel composite seamless pipe which comprises a concentric outer pipe and multiple layers of inner pipes. Grooves are arranged inside the outer pipe, mounting edges are arranged outside the inner pipes, clamping grooves are arranged inside the inner pipes, the clamping grooves and the mounting edges are alternately arranged, the mounting edges of an inner-layer inner pipe slide into the clamping grooves of the previous-layer inner pipe to be in clamped connection, and the mounting edges of the outermost-layer inner pipe slide into the grooves to be in clamped connection. The novel composite seamless pipe can composite inner pipes different in pipe diameter and sectional shape to adapt to different mounting conditions, and compositing of the inner pipes made of different materials can realize different functions. The novel composite seamless pipe is simple and practical.
Description
Technical field
The present invention relates to pipe fitting field, be specifically related to a kind of weldless tube.
Background technique
Weldless tube is that one has hollow section, periphery does not have jointed rectangular
steel.Weldless tube is installed easy to connect, detachably easy for installation, and using effect is good.By the compound composite seamless pipe obtaining of different tubing, will improve greatly its usability.
Summary of the invention
For solving the deficiencies in the prior art, the object of the present invention is to provide a kind of NEW TYPE OF COMPOSITE weldless tube, pipe fitting that can compound different inner diameters.
In order to realize above-mentioned target, the present invention adopts following technological scheme:
A kind of NEW TYPE OF COMPOSITE weldless tube, it is characterized in that: comprise concentric outerhose and multilayer inner tube, described outer tube inside is provided with groove, the outside of described inner tube is provided with installation rib, inside is provided with draw-in groove, draw-in groove with rib alternative arrangement is installed, the installation rib of described internal layer inner tube slips into clamping in the draw-in groove of last layer inner tube, the installation rib of outermost surface inner tube slips into clamping in groove.
The degree of depth of aforementioned grooves and draw-in groove is identical.The height of described installation rib and the degree of depth of groove are suitable.
The cross section of aforementioned installation rib is equilateral triangle.The cross section of described groove and draw-in groove is triangle.
Aforementioned outer tube is seamless steel pipe, and described innermost layer inner tube is carbon steel tube, and described outermost surface inner tube is polypropylene tube.
Aforementioned inner tube sectional shape is circle, rectangular or polygonal.
Aforementioned multilayer inner tube is at least three layers.
Usefulness of the present invention is: a kind of NEW TYPE OF COMPOSITE weldless tube provided by the invention, inner tube that can compound different tube diameters different cross section shape, thereby adapt to different installation situation, the inner tube of multilayer unlike material is compound simultaneously, can realize different functions.Simple and practical.
Accompanying drawing explanation
Fig. 1 is the outer tube schematic diagram of a kind of NEW TYPE OF COMPOSITE weldless tube provided by the invention;
The implication of reference character in figure: 1 outer tube, 2 outermost surface inner tubes, 3 innermost layer inner tubes, 4 draw-in grooves, 5 install rib, 6 grooves.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is done to concrete introduction.
A kind of NEW TYPE OF COMPOSITE weldless tube, comprises concentric outerhose 1 and multilayer inner tube, and preferably, multilayer inner tube is at least three layers.Inner tube sectional shape is circle, rectangular or polygonal.Outer tube 1 inside is provided with groove 6, and the outside of inner tube is provided with installs rib 5, and the cross section that rib 5 is installed is equilateral triangle.Inside is provided with draw-in groove 4, draw-in groove 4 and installation rib 5 alternative arrangements.The installation rib 5 of internal layer inner tube slips into clamping in the draw-in groove 4 of last layer inner tube, and the installation rib 5 of outermost surface inner tube 2 slips into clamping in groove 6.Groove 6 is identical with the degree of depth of draw-in groove 4.The cross section of groove 6 and draw-in groove 4 is triangle.The height of rib 5 and the degree of depth of groove 6 are installed suitable.Outer tube 1 is seamless steel pipe, and innermost layer inner tube 3 is carbon steel tube, and outermost surface inner tube 2 is polypropylene tube.
When use, select the inner tube of different inner diameters, different cross section, unlike material according to different situations, the different inner tube of multilayer is slipped into and in draw-in groove, is carried out clamping and form multilayer inner tube by installation rib each other, slip into by the installation rib of inner tube the clamping of carrying out inner and outer pipes in outer tube groove again, form different composite seamless pipes, thereby adapt to different user demands.The material difference of the inner tube of selecting, thus different performances provided for composite seamless pipe.
More than show and described basic principle of the present invention, major character and advantage.The technician of the industry should understand, and above-described embodiment does not limit the present invention in any form, and all employings are equal to replaces or technological scheme that the mode of equivalent transformation obtains, all drops in protection scope of the present invention.
