Abstract
The utility model discloses a virtual wall steel pipe, which is characterized in that a pipe wall of the virtual wall steel pipe is formed by connecting adjacent annular assemblies, wherein the annular assemblies are bended into an annular steel pipe with the rectangular or square cross section, and in addition, both ends of the steel pipe are welded. The utility model has the advantages that only a pipe bending machine and a welding machine are needed during the manufacture of the large-diameter virtual wall steel pipe, the equipment is simple, the manufacture cost is low, in addition, the formed steel pipe ring has high rigidity, and is not easy to deform, the pipeline can bear higher pressure, and the purpose is wide.
Description
Technical field
The utility model relates to a kind of large diameter steel pipe road.
Background technique
The processing large diameter steel pipe is normally with the steel plate winding shaping in the prior art, and welding forms pipeline then, and the diameter of the pipeline of producing according to this method is big more, and manufacture difficulty is big more, and the diameter of pipeline is big more, and manufacture cost is high more.When the size of pipeline surpassed certain scale, the ring stiffness of holding tube then needed thicker steel plate if desired.And Plate Steel has increased deadweight, above drawbacks limit the manufacturing and the application of large diameter steel pipe.
The model utility content
The purpose of this utility model is: be directed to the deficiencies in the prior art, the empty wall steel pipe that provides a kind of pipe diameter can do very greatly.
The technical solution of the utility model is:
A kind of empty wall steel pipe is characterized in that: the tube wall of this void wall steel pipe is to be connected to form by adjacent ring-shaped component, and this ring-shaped component is to bend to ring, and the cross section that two ends weld together is rectangle or square steel pipe.
Supplementary technology scheme of the present utility model is as follows:
Preferably, adjacent ring-shaped component is by being welded to connect.
Preferably, adjacent ring-shaped component is by bonding connection.
Preferably, be welded with flange at the two ends of empty wall steel pipe.
Preferably, on the inside and outside wall of empty wall steel pipe, also has anticorrosive coat.
The beneficial effects of the utility model are: only need tube bender when making large diameter empty wall steel pipe and welding machine gets final product, and the simple low cost of manufacture of equipment, and the steel pipe ring stiffness height that forms, not yielding, pipeline can bear bigger pressure, and is of many uses; If adopt preservative treatment preferably, can also prolong the life-span of pipeline; In pipe ends welded flange, the conveniently connection between a plurality of pipelines easily.
Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is the empty wall steel pipe of the utility model embodiment's a schematic representation.
Fig. 2 is a tube wall sectional view embodiment illustrated in fig. 1.
Fig. 3 is the schematic representation of a ring-shaped component.
Fig. 4 is another embodiment's a schematic representation.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Specific embodiment of the utility model, a kind of empty wall steel pipe, as depicted in figs. 1 and 2, the tube wall 2 of this void wall steel pipe is to be connected to form by adjacent ring-shaped component 1, wherein ring-shaped component 1 as shown in Figure 3, each ring-shaped component 1 is by bending to ring, and the cross section that two ends weld together is that rectangle or square steel pipe constitute.
When making above-mentioned empty wall steel pipe, at first select size, square tube or quarter bend (cross section is the steel pipe of square or rectangle) that wall thickness is suitable, square tube or quarter bend is crooked and be welded into the annulus of certain diameter, the external diameter of annulus is consistent with the design outer diameter of steel pipes, circular square tube or quarter bend are welded together or bond together, promptly become desired empty wall steel pipe after the polishing.Empty wall steel pipe inside and outside wall is done preservative treatment can also obtain better decay resistance, the connection between the empty wall steel pipe for convenience can also be at the two ends of empty wall steel pipe welding upper flange 3, as shown in Figure 4.
Disclosed all features in this specification, or the step in disclosed all methods or the process except mutually exclusive feature and/or step, all can make up by any way.
Disclosed arbitrary feature in this specification (comprising any accessory claim, summary and accompanying drawing) is unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, unless special narration, each feature is an example in a series of equivalences or the similar characteristics.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
Claims (5)
1. empty wall steel pipe, it is characterized in that: the tube wall of this void wall steel pipe is to be connected to form by adjacent ring-shaped component, this ring-shaped component is to bend to ring, and the cross section that two ends weld together is rectangle or square steel pipe.
2. empty wall steel pipe according to claim 1 is characterized in that adjacent ring-shaped component is by being welded to connect.
