Description

Seamless steel pipe capable of being nested mutually

Technical Field

The utility model relates to a steel pipe, in particular to seamless steel pipe that can nest each other.

Background

In the existing pipeline assembly of engineering and the like, the pipe fitting connection mode usually connects the pipe fitting with the larger pipe diameter and the pipe fitting with the smaller pipe diameter in a sleeved mode. In the connection mode, the pipe fitting has no leakage-proof or loosening-proof structure, so that the leakage of the fluid circulating in the pipeline at the pipe fitting or the separation of two sets of pipe fittings is easy to happen in use.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a seamless steel pipe that can nest each other can improve its structural strength who cup joints the end of rigid pipe body for the end of cup jointing of rigid pipe body overlaps each other with other pipe fittings and establishes, and when making the pipe fitting binder ring tighten, can not take place to warp.

The purpose of the utility model is realized like this: a seamless steel pipe capable of being nested mutually comprises a rigid pipe body, wherein at least two sleeving ends are formed on the rigid pipe body, concave-convex alternate corrugated surfaces are formed at the sleeving end of the rigid pipe body, pipe holes are formed in the rigid pipe body, and the pipe holes are communicated with the sleeving ends.

As a further limitation of the present invention, the rigid pipe body is formed with the concave-convex corrugated surfaces at the ends of the respective sleeves.

As a further limitation of the present invention, the rigid pipe body is correspondingly and fixedly provided with a rigid bushing ring in the pipe hole of the at least one sleeving end.

As a further limitation of the present invention, the rigid collar is fixedly disposed in the pipe hole of the sleeved end of the corrugated surface of the rigid pipe body, and the rigid collar is formed with corrugated surfaces that are concave-convex and alternate, so as to be embedded and combined with the corrugated surfaces of the sleeved end of the rigid pipe body.

As a further limitation of the present invention, the rigid pipe body is a two-way pipe body, a three-way pipe body or a four-way pipe body.

Compared with the prior art, the beneficial effects of the utility model reside in that:

1. the utility model can improve the structural strength of the sleeve end of the rigid pipe body by utilizing the corrugated surface design of the sleeve end of the rigid pipe body, so that the sleeve end is sleeved with other pipe fittings, and the phenomena of deformation, roundness loss and the like can not occur when the pipe fitting binding ring is tightened, thereby effectively preventing the leakage of fluid in the pipeline at the joint of the pipe fittings;

2. the utility model discloses a set up the rigidity backing ring to further improve the structural strength of its cup joint end of rigidity body, ensure its cup joint end of rigidity body is established with other pipe fittings cover, and unlikely emergence is out of shape, loses effects such as circularity when tightening with the pipe fitting collar.

Detailed Description

The present invention will be further described with reference to the following specific embodiments.

Example 1

A mutual nesting seamless steel pipe as shown in fig. 1-3, which comprises a rigid pipe body 1, wherein the rigid pipe body 1 can be a two-way pipe body, a three-way pipe body or a four-way pipe body, etc., and at least two set of connecting ends 11 are formed on the rigid pipe body 1, and concave-convex corrugated surfaces 12 are formed at the at least one set of connecting ends 11 of the rigid pipe body 1, in the best embodiment of the present invention, concave-convex corrugated surfaces 12 are formed at each set of connecting ends 11 of the rigid pipe body 1, and pipe holes 13 are formed in the rigid pipe body 1, and the pipe holes 13 are communicated with each set of connecting ends 11.

When the rigid pipe is used and implemented, as shown in fig. 4-5, one end of the pipe 2 and a sleeve end 11 of the rigid pipe 1 of the present invention are connected, and then the sleeve end 11 of the rigid pipe 1 and the joint of the pipe 2 are fastened and fixed by a pipe fastening ring 3, and then the other end of the pipe 2 is fastened and fixed with a part 4 such as an air inlet of a cylinder of a vehicle or an air inlet pipe, and in addition, other sleeve ends 11 of the rigid pipe 1 of the present invention can also be fastened and fixed by the pipe fastening ring 3 by the pipe fastening ring 2 and the other parts 4 by the pipe fastening ring 2.

Utilize the utility model discloses a rigidity body 1 can provide firm fluid transport route, sets up through pipe fitting 2 in addition, then can provide suitable activity surplus between rigidity body 1 and the part 4 that is connected to be applicable to and must maintain the surplus of fairly moving between each part 4 such as vehicle engine room, in order to make things convenient for 4 installations of relevant parts such as advancing, exhaust, possess high fever, highly compressed environment again. And utilize the utility model discloses a rigid body 1 its cup joints 11 fashioned unsmooth alternate ripple face 12 designs of department, can improve the structural strength of rigid body 1 its cup joint end 11 to when making cup joint end 11 to be tightened by pipe fitting collar 3, unlikely emergence is out of shape, loses the circularity, forms phenomenons such as gap, with the smooth and easy nature of fluid circulation in the pipeline such as ensureing oil, gas, the condition such as gas leakage, oil leak takes place when avoiding waiting fluid flow to rigid body 1 and pipe fitting 2 junction.

Example 2

As shown in fig. 6-7, in another embodiment of the pipe fitting structure of the present invention, a rigid liner ring 5 is correspondingly fixed in the pipe hole 13 of at least one sleeve end 11 of the rigid pipe body 1, and the rigid liner ring 5 can be formed with corrugated surfaces 51 with alternate concave and convex on it, so as to be correspondingly embedded and combined with the corrugated surfaces 12 of the sleeve end 11 of the rigid pipe body 1, thereby further improving the structural strength of the sleeve end 11 of the rigid pipe body 1, so that the sleeve end 11 is sleeved with other pipe fittings, and when the pipe fitting ring 3 is tightened, the pipe fitting structure will not deform.
