Brass tube: A type of non-ferrous metal tube, li is a pressed and drawn seamless tube. Copper tubes are strong and corrosion-resistant, and have become the first choice for modern contractors to install water pipes, heating and cooling pipes in all residential commercial houses. Brass tubes are the best water supply pipes.
Brass tubi huma dawl in piż, have good thermal conductivity, and high low-temperature strength. They huma spiss użati biex manifattura sħana skambju tagħmir (bħal kondensaturi, eċċ.). Huma huma huma ukoll użati biex jarmaw temperatura baxxa pipelines in ossiġnu produzzjoni tagħmir. Ram tubi bi żgħar dijametri huma spiss użati biex trasport taħt pressjoni likwidi (bħal lubrikazzjoni sistemi% 2c żejt pressjoni sistemi, eċċ.) u bħala pressjoni gauges għal strumenti. Isfar tubi huma b'saħħithom u reżistenti għall-korrużjoni.
It mainly has the following advantages: Copper tubes are hard, not easy to corrode, and are resistant to high temperature and high pressure. They can be used in a variety of non-copper environments. Compared with brass tubes, the shortcomings of many other pipes are obvious. For example, galvanized steel pipes, which were used more in residential buildings in the past, are very easy to rust. After a short period of use, problems such as yellowing of tap water and reduced water flow will occur. Some materials will rapidly reduce their strength at high temperatures, which will cause unsafe hazards when used in hot water pipes. However, since the melting point of copper is as high as 1083 degrees, the temperature of the hot water system will have little effect on brass pipes. Common brass pipes include brass pipes for electrical appliances, brass pipes for refrigeration, high-pressure brass pipes, corrosion-resistant brass pipes, brass pipes for connections, brass pipes for waterways, electric heating brass pipes, and industrial brass pipes.
Prekawzjonijiet għal brass tube welding:
1. Matul iwweldjar, dejjem żomm il fjamma covering il joint to prevent air from entering;
2. The flux will be dried out, the water will evaporate at 100 degree , and the flux will turn milky white;
3. The flux will bubble at 316 degree ;
4. The flux will become paste at 427 degree ;
5. The flux will become fluid at 593 degree , close to the copper welding temperature;
6. Solder fih 35%-40% fidda will melt at 604 degree and flow at 618 degree ;
7. Agħti attenzjoni lil iż- żewġ biċċiet tax-xogħol biex tkun iwweldjata. Uża a iwweldjar torċa sa sħana ;
8. The color of the flame can be used to observe jekk the temperature is appropriate. When the temperature reachs the copper welding temperature, the flame will appear green, and when it reaches the silver welding temperature, the the green flame indics that the temperature the temperature is appropriate;
9. To weld copper pipes and steel pipes pipes to each other, the copper pipe must be heated first (għax the copper pipe conducts heats heat quickly and requires more heat);
10. Tuling the copper welding process, the welding torch should not always stop at one point, but can be moved in an 8-}}shaped shape;
11. It is huwa rrakkomandat to use a large welding torch, so that a soft flame can be used to achievein high heat without overpressure or "blowing". It is best to have a slight feather glow on the internal conical flame.
