Problems solved by technology
Existing equipment requires pipe fittings to be able to bear a large weight and not be too bulky, which poses new challenges to pipe fittings
The existing pipe fittings are hollow pipes. If the strength is pursued, the wall thickness needs to be increased, but in this case, the weight will be sacrificed.

The invention discloses a composite stainless steel pipe provided with connecting pipes. The composite stainless steel pipe provided with the connecting pipes comprises an outer pipe body and an inner pipe body arranged in the outer pipe body. The multiple connecting pipes are evenly distributed around the outer wall of the inner pipe body and arranged in the axial direction of the inner pipe body. The inner sides of the connecting pipes are connected with the outer wall of the inner pipe body. The outer sides of the connecting pipes are connected with the inner wall of the outer pipe body. The connecting pipes, the inner pipe body and the outer pipe body are integrally formed. The inner pipe body is arranged in the outer pipe body and fixedly connected with the outer pipe body through a certain structure, so that the thickness of the pipe wall is decreased, and the strength can be guaranteed while the weight is reduced.
Description
technical field [0001] The invention relates to a composite stainless steel pipe provided with a connecting pipe. Background technique [0002] In commercial display equipment, pipe fitting materials are indispensable and necessary components. Existing equipment requires pipe fittings to be able to bear a large weight and not be too bulky. Such requirements pose new challenges to pipe fittings. The existing pipe fittings are hollow pipes. If the strength is pursued, the wall thickness needs to be increased, but the weight is sacrificed in this way. How to find a perfect technical solution between strength and weight has become a problem in the technical field of the industry. Contents of the invention [0003] The purpose of the present invention is to overcome the defects in the prior art, and provide a composite stainless steel pipe with good strength and light weight provided with connecting pipes. [0004] In order to achieve the above object, the technical solution...
