Product: Oxygen-free copper busbar and copper bar with high conductivity
Type Specifications: T2, TU1, TU2, TAg
Copper busbar is a strip or bar of copper that conducts electricity, often produced with high purity oxygen-free copper ingot through extrusion and drawing processes, usually used in high and low voltage electrical equipment, switch contact, electrical distribution equipment, and bus slot, etc.

Q:I found a small whole on the water pipe in the basement. I am trying to fix it by welding myself. What type of alloy I should use on copper pipe, or it doesn‘t matter?: make sure all the water is out of the pipe. or u will not get a good solider joint.u need 95/5 soilder,sand cloth and soilder paste.cut out the bad spot and clean the pipe with the sand cloth,than the fitting next apply the soilder using a acid brush.make sure u don't touch the paste after it is applied.put the joints together and heat with a tourch.forces your heat at the middle of the fitting heat it all around.when it is hot enough the soilder will flow into the joint let cool and turn water back on good luck

Q:This boy at my school drank about 50ml - 100ml of copper sulfate - he had to be flown out by a helicopter & he needed a stomach pump - will he die?: Doubtful if he received immediate attention. However, copper(II) ions are quite dangerous. At high enough levels, all transition metal ions are toxic. Copper in particular can act as an electron carrier, due to the relative ease with which it can switch between +1 and +2 oxidation states. However, with quick action and the timely administration of an antidote (or a metal complexant that allows the metal to be removed) it can be treated satisfactorily.

Q:Who knows GREE air conditioning, two pieces of smallpox confidential, match what big copper tube?: If the five air-conditioning pipes of Q19 tube is Q12, three air conditioning crude is 16 of the fine is 10, 2 is 12 piece of coarse fine is 6, absolutely.

Q:i recently found that some of my live rock had some nasty free living flat worms so i put them in a container and dosed it with lots of copper.would it be impossible to re introduce that rock into my reef tank? or does it take lots of rinsing?: Not a good idea to reintroduce it. The copper bonds with the calcium carbonate in the live rock, and it will slowly leech out into your aquarium, which will be toxic to any invertebrates in the system. No amount of rinsing is going to get rid of it. Your could possibly use it in a quarantine tank for fish only, since copper isn't harmful to the fish, and it still contains some beneficial bacteria. Just don't put it back in your reef tank. Feeding less and vacuuming out as many worms as possible will help reduce the flatworm populations. Also, many small species of fairy wrasse will eat these worms, and keep their populations in check.

Q:I think this would look awesome since it would match the bronze drawer pulls. I have heard that the patina can be toxic. Or is just drinking from copper pipes that is bad? Advice please.: Put it in a metallic box with as few holes as possible. If you need holes keep them small. If you need ventilation then use a grid of holes. Hard to say more without any idea of the circuit. BEng MIEE

Q:Used in the central air-conditioning on the copper tube, which brand of copper pipe will be better, more durable?: The operation of refrigerant in the central air conditioner determines the use effect directly, so the quality of refrigerant copper tube is very important. The traditional R22 refrigerant (Freon) tube pressure is generally about 20 kilograms, and R410 new refrigerant, the pipe pressure reached 40 kg. Therefore, the central air conditioner that uses new refrigerant needs to choose better refrigerant copper pipe. Note: 410A environmental protection media require copper tube wall thickness to be thick enough.The installation of refrigerant copper tubes is the most important part of the installation process of central air conditioning. 1. All welding points shall be welded at the joint of the copper pipe and the branch pipe. There shall be no welding between the copper tube and the copper pipe. 2, in the welding process, must be in the copper tube into nitrogen (nitrogen welding process), this makes the copper pipe inside the air, avoid welding, so that the inner wall of carbon, so in the formal operation into the compressor and failure. 3. After welding, the high pressure nitrogen shall be used to blow ash in the pipe to keep the copper tube clean.Then nitrogen and pressure, this is the completion of welding must be carried out on the copper pressure test, to the copper tube filled with a certain pressure of nitrogen for holding pressure, the general pressure test time is 24 hours. It should be noted that the use of R410 refrigerant, you need to keep the pressure of 40 kg, R22 refrigerant, you need to keep the pressure of 20 kg. Nitrogen is an inert gas with a small coefficient of expansion. There is almost no change in pressure due to thermal expansion and cold contraction. If there is a decrease in the pressure gauge during the test, check that the refrigerant pipe is welded.

Q:Does copper + hydrogen ion create a reaction?: Yep, the copper is a metal and H+ ions come from acids. So copper (or any metal) plus acid gives a neutral salt plus hydrogen (gas). You;d probably observe some fizzing or something more vigorous, depending on how strong and concentrated your acid is.

Q:I have a steel bowl from a wooden pipe i had lying around and i can screw a peace of pipe to it where the tube goes and you put your lips on it. I heard its not safe if your bowl is copper but if you use it as a tube it should be fine. Is it ok to use it as a tube or should i just look for a steel tube I went to home depot and the only one that fit was a copper tube.: that would be foolish copper is toxic especially when heated the toxins will be released and will possibly harm you severely, Second of all WHAT are you smoking?

Q:how do you sweat solder copper pipes?: Yes, as well as the struts. The main reason is that nitrogen does not expand or contract with temperature changes or altitude changes.
