Problems solved by technology

[0003] At the same time, with the continuous development of industrial technology in recent years, the use of commercial air conditioners with larger capacity is also increasing. As a large-capacity air-conditioning system, the pressure requirements of the medium circulation system are relatively high, and copper materials are used as The connecting pipe does not bear as much pressure as the corresponding steel pipe, and consumes more copper. This is not conducive to cost control when copper prices remain high and resources are increasingly scarce.

Embodiment Construction

[0026] The technical solution of the present invention will be described below in conjunction with specific embodiments.

[0027] figure 1 It is a structural schematic diagram of a connecting pipe according to an embodiment of the present invention, figure 2 for figure 1 The A-A sectional structure schematic diagram of the middle connecting pipe, image 3 for figure 1 Schematic diagram of the processing flow of the connecting pipe in .

[0028] Such as figure 1 , figure 2 and image 3 As shown, the connecting pipe includes a base pipe and a copper plating layer plated on the inner and outer surfaces of the base pipe. Specifically, the connecting pipe includes a base pipe 1 and copper plating layers 11 and 12 plated on the inner and outer surfaces of the base pipe 1. In addition, the connecting pipe also includes a welding part 4. In this embodiment, one end of the connecting pipe is a welding part. The inner surface of the welding part 4 is used for welding connection...

Abstract

The invention relates to a connecting pipe. The connecting pipe comprises a base pipe made of low-carbon steel and copper plated layers on the inner surface and the outer surface of the base pipe, wherein the base pipe is a low-carbon steel pipe suitable for being welded, specifically such as an SPCC pipe, an SPCE pipe and a number-10 steel pipe, and at least one of two ends of the connecting pipe is provided with a welding portion can be welded with other pipe fittings, parts or connectors to perform connecting seal. The base pipe of the connecting pipe is made of the low-carbon steel replacing of a copper material, copper is plated on the inner surface and the outer surface of the base pipe, and by coating the copper plated layers, the requirement that a system needs to be welded in connection is met, the material cost is reduced, and simultaneously the weight of the air conditioning system is lightened.

Description

technical field [0001] The invention belongs to the technical field of refrigeration, and mainly relates to a connecting pipe, a manufacturing method thereof and an air-conditioning system using the connecting pipe. Background technique [0002] In the air conditioner or other forms of refrigeration systems in the prior art, since there are many parts in the system, and it is necessary to ensure that the connections between the parts are reliable and can be used for a long time without leakage, copper pipes are generally used as the connection of the pipelines. Tubes, and fixed connections by welding such as flame brazing, generally use copper tubes or brass tubes to meet the requirements of connection and welding. [0003] At the same time, with the continuous development of industrial technology in recent years, the use of commercial air conditioners with larger capacity is also increasing. As a large-capacity air-conditioning system, the pressure requirements of the m...
