Abstract
The utility model discloses a multilayer welding air pipe which comprises an outer sleeve welding pipe and an inner welding pipe, wherein a plurality of hollow cushion pipes are welded on the pipe walls of the inner sides of pipe bodies at two ends of the outer sleeve welding pipe, the hollow cushion pipes are distributed in an annular shape corresponding to the pipe bodies of the outer sleeve welding pipe, one end of each hollow cushion pipe is welded and fixed on the inner wall of the outer sleeve welding pipe, the other end of each hollow cushion pipe is welded on the outer wall of the inner welding pipe, and each hollow cushion pipe is in a deformed hollow pipe shape. Through the mode, the strength of the welded pipe can be improved through the double-layer structure, the outer sleeve welded pipe is sleeved outside the built-in welded pipe for protection, and the hollow cushion pipe is connected between the built-in welded pipe and the outer sleeve welded pipe and can be cushioned for shock absorption and protection treatment.
Description
Technical Field
The utility model relates to the field of welding, in particular to a multilayer welding air pipe.
Background
The welded pipe is also called as welded pipe, and is made by welding a steel plate or strip steel after curling and forming, and is generally 6 meters in fixed length. The welded pipe has simple production process, high production efficiency, various types and specifications and less equipment investment, but the general strength is lower than that of a seamless welded pipe. And the general welded pipe is used for a ventilating duct, and the pipe fittings are spliced into the air pipe by welding.
SUMMERY OF THE UTILITY MODEL
The utility model mainly solves the technical problem of providing a multilayer welded air pipe which can improve the strength of a welded pipe through a double-layer structure, wherein the outer part of an internal welded pipe is sleeved with an outer welded pipe for protection, and a hollow cushion pipe is connected between the internal welded pipe and the outer welded pipe and can be cushioned for shock absorption and protection treatment.
In order to solve the technical problems, the utility model adopts a technical scheme that: the utility model provides a multilayer welds tuber pipe, includes outer welded pipe and built-in welded pipe, the welding has a plurality of hollow filler pipes on the inboard pipe wall of outer welded pipe both ends body, hollow filler pipe with outer welded pipe body corresponds and is the ring form and distributes, hollow filler pipe one end welded fastening is in on the outer welded pipe inner wall, the welding of the hollow filler pipe other end is in on the built-in welded pipe outer wall, hollow filler pipe is the hollow tubulose of deformation form.
In a preferred embodiment of the utility model, the outer sleeve welded pipe and the inner welded pipe are connected and isolated through the hollow cushion pipe.
In a preferred embodiment of the present invention, the outer welded pipe is a square welded pipe or a triangular welded pipe.
In a preferred embodiment of the present invention, the built-in welded pipe is a circular welded pipe.
The utility model has the beneficial effects that: the utility model can improve the strength of the welded pipe through a double-layer structure, the outer sleeve welded pipe is sleeved outside the built-in welded pipe for protection, and a hollow cushion pipe is connected between the built-in welded pipe and the outer sleeve welded pipe and can be cushioned for shock absorption and protection treatment.
