Along with growth in the living standard, the machinery of processing and carrier mostly has high safety and reliability requirement for equipment and materials, original common stainless steel carft of construction, may not necessarily adapt to modern industry environment for safety and the reliability requirement of the industries such as logistics.Original steel pipe is easily corroded in use, and steel strength is more weak, has shortened the working life of steel pipe, and the replacing of steel pipe, installation and maintenance are cumbersome, also exists and is connected unsettled defect with installation connecting element.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of pneumatic steel cylinder seamless steel pipe, can improve the support strength of seamless steel pipe, and long service life is simple in structure.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: a kind of pneumatic steel cylinder seamless steel pipe is provided, it is characterized in that, comprise: outer tube body, described outer tube body inside is provided with interior tube body, is provided with a plurality of supporting portions on described outer tube body, described supporting portion comprises left support portion and right support portion, described left support portion is connected with right support portion, and described left support portion stretches out in outer tube body, and right support portion contacts with interior tube body.
In a preferred embodiment of the present invention, the cross section of described left support portion is circular arc, and the cross section of described right support portion is triangular in shape.
In a preferred embodiment of the present invention, described outer tube body, supporting portion and interior tube body are formed in one, and the quantity of described supporting portion is 4.
In a preferred embodiment of the present invention, on described interior tube body and outer tube body, be coated with antioxidant layer, described interior tube body internal coat has pickling layer.
In a preferred embodiment of the present invention, the cross section of described outer tube body and interior tube body is cylindrical.
The invention has the beneficial effects as follows: the pneumatic steel cylinder seamless steel pipe of the present invention, can improve the support strength of seamless steel pipe, long service life, simple in structure.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the embodiment of the present invention, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also according to these accompanying drawings, obtain other accompanying drawing, wherein:
Fig. 1 is the structural representation of seamless steel pipe one preferred embodiment for the pneumatic steel cylinder of the present invention;
In accompanying drawing, the mark of each parts is as follows: 1, outer tube body, 2, interior tube body, 3, supporting portion.
Embodiment
Below the technological scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Embodiment based in the present invention, those of ordinary skills, not making all other embodiments that obtain under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, a kind of pneumatic steel cylinder seamless steel pipe, it is characterized in that, comprise: outer tube body 1, described outer tube body inside is provided with interior tube body 2, is provided with a plurality of supporting portions 3 on described outer tube body 1, described supporting portion 3 comprises left support portion and right support portion, described left support portion is connected with right support portion, and described left support portion stretches out in outer tube body 1, and right support portion contacts with interior tube body 2.
In addition, the cross section of described left support portion is circular arc, and the cross section of described right support portion is triangular in shape.
In addition, described outer tube body 1, supporting portion 3 and interior tube body are 2 one-body molded, and the quantity of described supporting portion 3 is 4.
In addition, on described interior tube body 2 and outer tube body 1, be coated with antioxidant layer, described interior tube body 2 internal coats have pickling layer.
In addition, the cross section of described outer tube body 1 and interior tube body 2 is cylindrical.
Be different from prior art, the pneumatic steel cylinder seamless steel pipe of the present invention, can improve the support strength of seamless steel pipe, and long service life is simple in structure.
