The competition of refrigeration copper pipe market is fierce, so it is necessary to expand new fields and enhance the competitiveness of products. Copper prices, which had been running at high levels in 2012, continued to fall in 2013, while the processing prices of refrigerated copper tubes also showed a downward trend. With the implementation [...]
Copper pipe welding technology is the most important part, and it is an important guarantee whether the copper pipe can be successfully put into use in various industries. The position of filler metal is about 2 mm above the nozzle, and the position of filler metal must be guaranteed in the front and back of [...]
The main contents of copper pipe welding include the structure and types of copper pipe welding flame and preheating state. Welding flame structure is divided into three parts: flame core, internal flame and external flame, and the temperature is the highest at 3 mm in front of the flame core, which can reach about 3,000 [...]
This article is a special part of the inspection of copper pipe welding. According to the gradual inspection of unqualified items, it is necessary to rework if problems arise. The inspection unqualified items of copper pipe welding are as follows: 1. Overburning: Appearance judgement shows that there are burn marks and rough pits in the [...]

Processing Technology of Air Conditioning Copper Pipes At present, casting-rolling process is the mainstream process for air conditioning copper pipes. Detailed steps of this process are described as follows: 1. As-cast billet is obtained by horizontal continuous casting of electrolytic copper sheet. 2. Melting and casting: As-cast billet is obtained by three-roll planetary rotary rolling. [...]
What's the difference between hard copper tube and soft copper tube? Copper tube, a kind of non-ferrous metal tube, is a seamless tube pressed and drawn. It is characterized by light weight, good thermal conductivity, high low temperature strength and corrosion resistance. Because of these excellent properties of copper pipes, the use of copper tubes [...]
