Abstract
An adjustable butt welding flange which can be rotated around its cooperated tube in 360 DEG comprises a short tube and a flange. First the short tube is cooperated with the flange (which means the external cylindrical of the short tube is cooperated with the inner bore of the flange), then the groove at the position A of the short tube is butt welded with a pipe set with the same specification, after the butt welding is finished the flange can be rotated around the short tube in 360 DEG because of clearance fit of the short tube and the flange, and thus the purpose is achieved that the flange is easy to be connected with other flanges by butt joint.
Description
Affiliated technical field
The utility model relate to a kind of can with the adjustable welding neckflange of other pipe welding, flange can revolve three-sixth turn around the short tube that is mated.
Technical background
At present, when the liquid communication pipeline that flange is connected is grouping welding, if as a flanged (FLGD) pipe fitting in two, wherein after the flange welding, another sheet flange with can be welded on the pipe after its flange hole aligns, so not only time-consuming but also effort causes very big waste to manpower and materials, and easily weldering is partially.
Summary of the invention
The utility model provides a kind of pipe and pipe to be grouping the abutted flange of welding at the existing in prior technology problem.
The technical solution adopted in the utility model is: adjustable welding neckflange is made up of short tube and flange two-part, and the sealing surface of flange is the part of short tube, short tube one end and flange Spielpassung.In addition, on the short tube the other end groove is arranged; In addition, described groove can with the mouth of pipe butt welding of other same size.
Owing to adopt said structure, after the pipe fitting welding of short tube and its same size is finished,, rotate so flange can be made 360 degree around short tube, to reach flange and the easy purpose of connecting of other flanges because short tube and flange are Spielpassung.The present invention has changed the shortcoming that original flange and pipe directly weld easy deformation, makes original fillet weld change the downhand weld welding into, and it is easier to weld.
Description of drawings
Fig. 1 is an outline drawing of the present utility model.
Fig. 2 is the J-J sectional structure chart of Fig. 1.
Among the figure: 1. short tube, 2. flange.
Embodiment
Adjustable welding neckflange of the present utility model is made up of short tube 1 and flange 2 two-part, and the sealing surface of flange is the part of short tube, short tube one end and flange Spielpassung.A place on the short tube the other end has been provided with groove, this groove can with the mouth of pipe butt welding of other same size.
During use, at first short tube 1 is cooperated (cylindrical of short tube 1 cooperates with flange 2 endoporus, and promptly short tube 1 is with after flange 2 cooperates, and flange 2 is enclosed within the outside of short tube 1) with flange 2, and short tube cooperates with flange the end face of back short tube to exceed the end face of flange.Then, with the pipe fitting welding of the A place groove and the same size of short tube.
Claims (3)
1. an adjustable welding neckflange is made up of short tube and flange two-part, and the sealing surface of flange is the part of short tube, it is characterized in that short tube one end and flange Spielpassung.
