The copper tube has become an indispensable accessory for people's lives, and it is related to people's quality of life. Today, we will take a look at the connection technology and development direction of copper pipes.

1. The crystallization characteristics of copper alloys of various compositions are different, the casting performance is different, and the casting process is also different.

1. Tin bronze: The crystallization characteristic is that the crystallization temperature range is large and the solidification area is wide; the casting performance is characterized by poor fluidity, easy to produce shrinkage, and not easy to oxidize; the process is characterized by directional solidification of thick wall parts, complex thin-walled parts, and general Thick wall parts are taken to solidify at the same time.

2. Aluminum bronze and aluminum brass: The crystallization characteristic is that the crystallization temperature range is small, and it is the characteristic of layer-by-layer solidification; the casting performance is characterized by good fluidity, easy to form concentrated shrinkage cavity, and easy to oxidize; the process characteristic is aluminum bronze casting The system is a bottom injection type, and the aluminum brass gating system is an open type.

3. Silicon brass: The crystallization characteristic is between tin bronze and aluminum bronze; the casting performance is the best; the process characteristic is the sequential solidification process, the middle casting type gating system, and the dark riser size is small.

Second, the connection technology of the copper pipe

The firmness of the copper tube is very strong, especially in connection. Nowadays, there are many kinds of pipes on the market, and the interface fittings are mainly copper pipes. For example, there must be a copper fitting where the copper pipe and the faucet interface. Because copper pipe fittings are connected to other pipe materials, the physical and mechanical properties of the pipes and fittings are different due to the difference in thermal expansion and contraction, so the firmness of the connection will naturally be subject to additional challenges. Therefore, the firmness of the connection between the copper tube and the copper fittings will be greatly enhanced.

Third, the development direction of copper pipe

Although the copper tube has strong performance and can adapt to different working environments, due to the uncertainty of the market, there is no guarantee for its development. In the future, before seizing new opportunities, it is still necessary to ensure the quality of copper pipes. This not only requires strict supervision of the market, but also the supervision of the manufacturers themselves. Secondly, the water pipeline in the construction field is a relatively complete system, and the current application of copper pipes in this area is only a small aspect; but if the application of supporting facilities can be developed, this kind of pipeline will be more reasonably applied to the complete system. The system not only facilitates the establishment of water pipes, but also enables the copper pipes to develop new markets.
