Description

Novel seamless flange pipe
Technical field
The utility model relates to a kind of pipe fitting, particularly the novel flange pipe of one, is adapted to the transfer line that pressure is high, wear extent large, often dismantle.
Background technique
Flange pipe is through special mechanical equipment by the sizing of tubing two ends heating flange; change traditional flange welding or the issuable solder skip phenomenon of gasket ring hot-melt adhesive paste, product is widely used in the needs of the industry construction such as oil, chemical industry, medicine, electric power, space flight, military project, fire-fighting, metallurgy, shipbuilding, combustion gas, nuclear power, urban construction, hot-water heating and environmental protection and maintenance.In use, often due to bottom surface out-of-flatness or other factors of flange, make it and dock pipeline and not exclusively seal, docking site is easily leaked, and causes economic loss to user.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of novel seamless flange pipe, comprises body, groove, flange, seal groove.
The utility model solves the technological scheme that its technical problem adopts: overall body is that special mechanical equipment is by tubing heating one end processing one-step building, flange bottom surface and body hole wall form right-angle structure, flange center line is vertical with body centerline hole, the bottom surface of flange is provided with seal groove, seal groove has three roads, three seals groove is concentric circle annular groove, settles seal ring in seal groove; The body the other end is provided with groove, and groove is " V " word shape.
The utility model beneficial effect: convenient welding, good seal performance, beautiful shape, increases the service life.
Accompanying drawing explanation
Fig. 1 is the utility model overall structure schematic diagram;
In figure, 1, body, 2, groove, 3, flange, 4, seal groove.
Embodiment
As shown in drawings, the utility model comprises body 1, groove 2, flange 3, seal groove 4, overall body 1 is that tubing heating one end is processed as one-step building by special mechanical equipment, to elongation of turning up on tube wall, it is the vertical edge of diameter after terminating until be shaped, flange 3 rapid shaping prevents bore edges to break, guarantee that seamless-molding is processed, flange 3 bottom surface and body hole wall form right-angle structure, flange 3 center line is vertical with body centerline hole, the bottom surface of flange 3 is provided with seal groove 4, seal groove 4 has three roads, three seals groove 4 is concentric circle annular groove, seal groove 4 li settles seal ring, guarantee that flange 3 bottom surface and pipeline seal completely, body 1 the other end is provided with groove 2, and groove 2 is " V " word shape, when the groove 2 of " V " word shape is connected with pipeline, under the squeeze flow effect of pipeline, form nature sealing, and carry out welding processing at body 1 and pipeline junction, weld layer forms secondary seal, extends body 1 working life.
