  • Advantages of copper tubes

    The copper tubes have a hard texture, is not easy to corrode, and is resistant to high temperature and high pressure, and can be used in various environments. Compared with this, the shortcomings of many other pipes are obvious. For example, the galvanized steel pipes used in the past are very easy to rust, and the problems such as yellowing of the tap water and small water flow will occur after a short time. The strength of some materials will decrease rapidly at high temperatures, which will cause hidden dangers when used in hot water pipes. The melting point of copper is as high as 1083 degrees Celsius, and the temperature of the hot water system is negligible for copper…

  • Material and characteristics of copper clad laminate

    1. Copper-clad phenolic paper laminate: It is a laminated product made of insulating impregnated paper (TFz-62) or cotton fiber impregnated paper (1TZ-63) impregnated with phenolic resin after hot pressing. A single sheet of alkali-free glass impregnated tape is attached, and copper foil is applied to one side. Mainly used as a printed circuit board in radio equipment. 2. Copper-clad phenolic glass cloth laminate: It is a laminated product made of alkali-free glass cloth impregnated with epoxy phenolic resin and hot-pressed. It is covered with copper foil on one or both sides. It has light weight, electrical and mechanical properties. Good performance, easy processing and other advantages. The board surface is light yellow. If tricyandiamide is used as the curing agent,...

  • Busbar tar-ram

    Busbar tar-ram, also known as copper bus bar or copper bus bar, is made of copper material and has a rectangular or chamfered (rounded) rectangular long conductor (now generally used round copper bar to avoid tip discharge), in the circuit Plays the role of carrying current and connecting electrical equipment. Copper bars have been widely used in electrical equipment, especially in complete power distribution devices. Copper bus bar is one of the main varieties of copper processing materials. Copper busbars have high mechanical properties, good electrical conductivity, thermal conductivity, excellent corrosion resistance, electroplating, brazing, beautiful and beautiful metallic luster and good forming processing performance, eċċ. Power transmission and transformation, electrical equipment, eċċ. have been widely used in the field of…

  • Tubu tar-ram

    Copper tube is also called red copper tube. One kind of non-ferrous metal pipes are pressed and drawn seamless pipes. Copper pipes have the characteristics of good electrical conductivity and thermal conductivity, the main materials of conductive accessories and heat dissipation accessories of electronic products, and become the first choice for modern contractors to install tap water pipes, heating and cooling pipes in all residential commercial houses. The copper pipe has strong corrosion resistance, is not easy to oxidize, and is not easy to chemically react with some liquid substances, and is easy to bend and shape. The copper pipe is light in weight, good in thermal conductivity, and high in low temperature strength. Commonly used in the manufacture of…

  • The use of copper bus

    1. Welding characteristics and welding process of copper bus bar There are two types of copper busbar connection at the power station: bolt fastening and welding. Copper has excellent electrical conductivity Properties, thermal conductivity, heat resistance, and processability, pure copper is industrial pure copper with a wcu of not less than 99.5%. 2. Copper welding characteristics 1.High thermal conductivity The thermal conductivity of pure copper is 8 times greater than that of carbon steel at room temperature. Pure copper weldments are locally heated to the melting temperature. A large amount of heat is required; therefore, a heat source with concentrated energy is needed during welding, otherwise the heat will be quickly dissipated, and the weldment should be preheated when welding…

    Copper tube straightening: 1. For the straightening of copper and copper alloy pipes, first fill the pipe with sand, and then use a straightener to straighten: you can also place the sand-filled copper pipe on a flat plate or a workbench. Plate, and then use a rubber mallet, wooden clog or square wood to tap lightly along the tube to straighten it piece by piece 2. Pay attention not to apply excessive force during the straightening process, and do not produce hammer marks, pits, scratches or rough marks on the surface of the pipe. Design logistics should clean up the residual sand in the pipe. Cutting: 1. Copper and copper alloy tubes can be cut with hacksaws and abrasive saws,...

  • Introduction of copper tube

    Copper and brass pipeline installation This process standard is applicable to copper pipes and working pressures with a working pressure below 4MPa and a temperature of 250 ~ -196C. Installation of brass pipes with a force of 22 MPa or less and a temperature of 120 ~ -158 “C. Common materials for construction preparation: 1. Pipes: Commonly used copper pipes and brass pipes are divided into control pipes, rolled pipes and extruded pipes according to different manufacturing methods. Generally, medium and low pressure pipes are drawn pipes. The commonly used materials for copper pipes are divided into three types: soft, semi-rigid and hard. 2. Copper alloy. In order to improve the performance of brass, adding tin, manganese, lead, zinc, phosphorus and…
