Abstract
The utility model discloses a thin-wall stainless steel connecting pipe for delivery. One or more bulges (11) is arranged axially on the same ring surface near pipe body (1). The thin-wall stainless steel pipe for delivery with the above construction works with related connecting pipe fittings to provide tight and firm connection, protection of weld joints, easy installation and greatly improved original strength and status of the protected pipe.
Description
Technical field
The utility model relates to a kind of Stainless Steel Tube, and particularly a kind of thin-wall stainless steel is carried connecting tube.
Technical background
The connection of existing Stainless Steel Tube, the way that all adopts tube wall domain generation deformation connects purpose (as groove snap ring mode etc.) to reach, so just make the local pipe thickness attenuation of tubing domain generation deformation, reduced the intensity of tubing in the joint, simultaneously, domain tube wall generation deformation more makes the weld of thin-wall stainless steel follow with avoiding deformation takes place together, the intensity and the sealingly secure degree of weld seam are affected, fail to keep its original state.
The model utility content
The technical problems to be solved in the utility model is that a kind of more excellent connecting tube that can avoid thin-wall stainless steel pipe end domain generation deformation will be provided, and can reduce the area of tube wall generation deformation, better original state of holding tube.The more important thing is that the soldered position of having avoided thin-wall stainless steel in the joint of pipe causes deformation and destroys, the original state of holding tube weld and intensity better, thus protected the welding part of pipe.
For solving the problems of the technologies described above, the technical solution of the utility model is: provide a kind of thin-wall stainless steel to carry connecting tube, body is near on the same anchor ring in end more than one some places ridge being arranged radially.
Aforesaid thin-wall stainless steel is carried connecting tube, and the geometrical shape of ridge is the semicircle curved surface.
Aforesaid thin-wall stainless steel is carried connecting tube, and several ridges that swell near pipe end are on the same anchor ring of pipe.
Aforesaid thin-wall stainless steel is carried connecting tube, and several ridges of protuberance are the space to each other, between promptly adjacent two ridges some distances are arranged.
Adopt the thin-wall stainless steel of said structure to carry connecting tube, cooperate the relevant connection pipe fitting just can seal, link together securely, have protection weld seam, green strength easy for installation and raising protection tubing greatly and the advantage of state.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the sectional drawing that thin-wall stainless steel is carried connecting tube:
Fig. 2 is the sectional top view that thin-wall stainless steel is carried connecting tube;
Fig. 3 is that thin-wall stainless steel is carried connecting tube and relevant connection pipe fitting assembly schematic representation.
Embodiment
Referring to Fig. 1, Fig. 2, can utilize the connecting tube special pressure instrument of special manufacturing, make thin-wall stainless steel carry connecting tube radially to produce some places ridge 11 near pipe end, can be one, also can be two or more.Some places ridge 11 has some distances between adjacent two ridges (11) on the same anchor ring of body 1, promptly be the space each other.Several ridges of body 1 can be avoided the welding part of thin-wall stainless steel when shaping, can protect the original state of pipe weld seam.Span between adjacent two ridges can be avoided the weld of thin walled tube, can not be damaged in the welding part of joint by protective tube.
Referring to Fig. 3, wherein, the 2nd, the connection pipe fitting body, the 3rd, metal washer, the 4th, the colloid seal ring, the 5th, inner nut inserts in the connection pipe fitting body 2 from right to left in the direction of arrows, tightens inner nut 5 and gets final product.
Claims (4)
1, a kind of thin-wall stainless steel is carried connecting tube, it is characterized in that: body (1) is near on the same anchor ring in end more than one some places ridges (11) being arranged radially.
2, thin-wall stainless steel according to claim 1 is carried connecting tube, and it is characterized in that: the geometrical shape of ridge (11) is the semicircle curved surface.
3, thin-wall stainless steel according to claim 1 is carried connecting tube, it is characterized in that: several ridges (11) near the pipe end protuberance are on the same anchor ring of body (1).
4, thin-wall stainless steel according to claim 1 is carried connecting tube, and it is characterized in that: several ridges (11) of protuberance are the space to each other, between promptly adjacent two ridges (11) some distances are arranged.
