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 [...]
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 [...]
Main usage of Copper pipes become widely that is a non-ferrous metal closely related to human beings. It is widely used in electrical, light industry, machinery manufacturing, construction industry, national defense industry and other fields. It is second only to aluminum in the consumption of non-ferrous metal materials in China. Main usage of copper pipes [...]
Copper pipe gas welding materials and preparation work include welding wire, organic flux, cleaning tools, etc. 1. Welding wire should be used as filler metal in gas welding of welding wire; one is the welding wire containing deoxidizing elements, such as wire 201 and 202; the other is the general cut of copper wire and [...]
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 [...]
Purple copper tubes are one of the copper tubes, and can conduct heat, in the environment temperature comparison situation will not crack, can be used normally. Purple copper tubes have fine structure and low oxygen content. No pore, trachoma, loose, good electrical conductivity, high surface accuracy of the electro-etched die, heat treatment process, non-directional electrode, [...]
Why do EDM punchers use electrodes copper tubes? Electric spark punching machine is commonly known as piercing machine, piercing machine, small hole discharger, fine hole machine. Electrodes copper tubes working principle is to use continuous vertical movement of copper tube (called electrode wire) as the electrode to remove metal from the workpiece by pulse spark [...]
Flared copper tube - safe and reliable The flared copper tube combines the advantages of metal tubing with non-metallic tubing. It is harder than plastic pipe and has high strength of general metal (the strength of cold drawn copper pipe is equivalent to that of steel pipe of the same wall thickness); it is more [...]
Dephosphorization copper pipe connection Before the dephosphorization copper pipe is straightened, the straightening should be done before the tube is filled with sand and then straightened with a straightener; during the straightening process, the force should not be too large, and the surface of the tube should not be hammered, pitted, scratched or rough. Mark [...]
The u-shaped copper tube is one of the more materials used in industrial equipment. The u-shaped copper tube is not only hard in texture, is not easily deformed, and has a long service life and does not need to be replaced. But many times, the use of u-shaped copper tubes requires some processing, and welding [...]
According to the different copper pipe appliances and their working modes, there are two commonly Copper Pipe Welding Methods, one is pulse copper pipe welding, which is mainly used for single-point fixed continuous and thin material welding, forming a circular weld when welding; the other is continuous copper pipe welding, which is mainly used for [...]
Copper pipe has light weight, good thermal conductivity and high low temperature strength. It is often used to manufacture heat exchange equipment (such as condenser). Copper pipes are also used to assemble cryogenic pipes in oxygen plants. Copper pipes with small diameters are often used for transporting pressurized liquids (such as lubrication systems, oil pressure [...]
Copper pipes (also known as copper tubes) are often used in water pipes, heating and refrigeration pipes, and can be used in different environments. Copper pipes have the advantages of both metal and non-metal pipes in hot and cold water systems. It is the best connecting pipeline. Copper tubes are fire-resistant and heat-resistant, and can [...]
