By adopting technique scheme, annular is arranged in butt convex edge, while being socketed pipeline like this on this end, can prevent the relative connecting tube axial float of pipeline, also can be to playing preliminary seal action between connecting tube and pipeline, when welding groove is arranged to annular and is facilitated connecting tube and pipeline welding, welding fluid can flow into welding groove, and flow along welding groove, make the circumferential welding between pipeline and connecting tube more comprehensive, some radially welding grooves are set, in the time of welded pipe line and connecting tube, welding fluid flow in each radially welding groove, circumferentially strengthen the abundant welding of pipeline and connecting tube, thereby welding groove and radially welding groove coordinate the stability in the time that circumferential and axial are strengthened pipeline and connecting tube welding between the two.
Further improvement as technique scheme: the degree of depth of described some welding grooves is all suitable with the degree of depth of welding groove radially.
By adopting technique scheme, welding groove is with radially the degree of depth between welding groove is suitable, and in when welding, the flow direction and the amount of welding fluid are more prone to control, also convenient while processing connecting tube.
The utility model is further set to: described flange plate is distributed with some contiguous blocks and some shape quantity suitable connecting groove with it away from one end even circumferential of connecting tube.
By adopting technique scheme, connecting tube and connecting groove are set, while docking between the flange plate of two piping flanges like this, the contiguous block of any one in two flanges will be absorbed in connecting groove, between multiple, fasten, then by the flange plate of two docking after the fastening pieces such as bolt are fastening, between two flange plate, be not easy radial misalignments, and in external force during in circumferential twisting flange, between flange plate, except fastening piece fastening, also have the grafting of contiguous block and connecting groove, fastening piece is not easy fracture and damages.
The utility model is further set to: described flange plate is distributed with two contiguous blocks and two connecting grooves away from one end even circumferential of connecting tube, and described contiguous block and connecting groove interval arrange.
By adopting technique scheme, when two contiguous blocks and connecting groove interval arrange, not only easy to process, and convenient in the time of design and installation hole, in the time of docking two flange, be more prone to.

Embodiment
Referring to figs. 1 through Fig. 4, the utility model piping flange embodiment is described further.
A kind of piping flange, comprise flange plate 2 and one end connecting tube 1 that one is connected with it, on described flange plate 2, offer some mounting holes 21, described connecting tube 1 is provided with the butt convex edge 11 and the welding groove 12 that all arrange ringwise away from the outer wall of flange plate 2 one end, described welding groove 12 is between flange plate 2 and butt convex edge 11, between described butt convex edge 11 and welding groove 12, be provided with axial clearance, described connecting tube 1 is distributed with some radially welding grooves 13 in the outer wall even circumferential at axial clearance place, the axis of the axis of described radially welding groove 13 and connecting tube 1 be arranged in parallel, conflict and be connected with butt convex edge 11 and welding groove 12 respectively in the axial two ends of described some radially welding grooves 13.
By adopting technique scheme, annular is arranged in butt convex edge 11, while being socketed pipeline like this on this end, can prevent relative connecting tube 1 axial float of pipeline, also can be to playing preliminary seal action between connecting tube 1 and pipeline, when welding groove 12 is arranged to annular and is facilitated connecting tube 1 with pipeline welding, welding fluid can flow into welding groove 12, and flow along welding groove 12, make the circumferential welding between pipeline and connecting tube 1 more comprehensive, some radially welding grooves 13 are set, in the time of welded pipe line and connecting tube 1, welding fluid flow in each radially welding groove 13, circumferentially strengthen the abundant welding of pipeline and connecting tube 1, thereby welding groove 12 and radially welding groove 13 coordinates between the two stability in the time that circumferential and axial are strengthened pipeline and connecting tube 1 and welded (certainly butt convex edge 11 with weld groove 12 and also can be arranged to sectional 1/4th annulars, or two section of 1/3rd annular, but consider easy to process, moreover welding fluid easily flows out from welding groove 12 when soldering, thereby cause welding inhomogeneous, therefore adopt the present embodiment better).
