Description
Technical field
The utility model relates to steel pipe manufacture field, particularly relates to a kind of pipe heating device.
Background technology
Conveyance conduit due to fed distance long, therefore conveyance conduit is connected to form by pipeline welding, during pipeline welding, needs to heat pipeline, to reach welding requirements.But conventional tube heating devices heat is uneven, there will be temperature of steel pipe part and reach welding requirements, and another part does not reach the requirement of welding, not only cause the waste of the energy, more drastically influence the quality of welding, there is certain potential safety hazard to when subsequent delivery pipe transport gas, oil etc.Find after deliberation, heater one of them key factor uneven to pipeline heating is the position residing in heater of steel pipe is not center, the position of usual steel pipe in heater is, because affecting bottom steel pipe of deadweight directly contacts with heater inwall, and steel pipe top distance heater inwall is distant.
Utility model content
The technical problems to be solved in the utility model is, overcomes steel pipe in prior art in heater, heats uneven deficiency, provide a kind of pipe heating device.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is, a kind of pipe heating device, and described device portal place has the positioner for steel pipe location.
Utilize positioner steel pipe to be fixed on the central authorities of heater, ensure that steel pipe is heated evenly in heating process.
Particularly, described device is tubular, comprises shell, insulating, zone of heating and heat conduction protective layer from outside to inside successively, and described tubular device two ends are installed with annular end cap, and described positioner is fixedly mounted on end cap.Zone of heating can use heater strip, and heater strip uniform winding, on heat conduction protective layer, ensures all directions heating evenly.
As preferably, described positioner comprises and is fixedly mounted on retainer ring on end cap and bolt, the center line of retainer ring opening and the center line of end cap opening are on same straight line, described retainer ring offers some screwed holes, and described bolt is connected with retainer ring by screwed hole.By steel pipe through retainer ring, arrive in heating chamber, adjustment bolt positions steel pipe, makes steel pipe be positioned at the center position of heating chamber.
As preferably, described uniform 3 screwed holes of retainer ring circumference.
As preferably, described positioner can also be, comprise and be fixedly mounted on retainer ring on end cap and bracing frame, support frame as described above comprises support bar and is arranged on the curved support plate of supporting bar top, described support bar is threaded rod, described retainer ring bottommost offers the screwed hole matched with described support bar, and support bar is connected with retainer ring by screwed hole.By steel pipe through retainer ring, arrive in heating chamber, steel pipe contacts with gripper shoe, transfer support bar, both can realize the location of steel pipe position, makes steel pipe be positioned at the center position of heating chamber.The utility model does not limit to above two kinds of positioner embodiments, and other can adjust steel pipe, and all can be applicable to as positioner of the present utility model, all in the utility model protection domain to the device that steel pipe plays positioning action.
As preferably, for convenience of the movement of device, described bottom of device is also provided with wheel.
The beneficial effects of the utility model are, apparatus structure is simple, easily operates, utilizes positioner steel pipe to be fixed on the central authorities of heater, ensure that steel pipe is heated evenly in heating process, thus ensure that the welding quality of steel pipe.
