Embodiment
Core of the present utility model is for providing a kind of heating unit for pipeline partial heat treatment, and this heating unit can improve pipeline thermal processing efficiency.
In order to make those skilled in the art understand better the technical solution of the utility model, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Please refer to Fig. 1 and Fig. 2, Fig. 1 is for the structural representation of the heating unit of pipeline partial heat treatment in a kind of specific embodiment of the utility model; Fig. 2 is the structural representation of A-A direction in Fig. 1.
The utility model provides a kind of heating unit for pipeline partial heat treatment, comprise for needing thermal treatment position that the heater block of heat is provided to described pipeline, heater block can be belt electric heater, can be also other form, as long as can realize technique effect herein.
Heating unit in the utility model also comprises load bearing component, and heater block integrated installation is in load bearing component, and the heating surface that matches of the partial heat treatment position of formation and pipeline; Like this; heating unit in the utility model uses when steel pipe circular seam is carried out to partial heat treatment; because heater block is fixed in load bearing component in advance; only need load bearing component and steel pipe is fixing; without site layout project and binding heater block; greatly improved the working efficiency of steel pipe circular seam partial heat treatment, and load bearing component can play certain provide protection to heater block, reduce heater block damage probability in handling process.
