Remark:These are common sizes which the company is making,and unusaal sizes with special requirement can be tailor-made against order.

the inside surface area increases 70~100% than that of the same specification of plain copper tube, the heat transfer coefficient is about 1.8~2.0 times of that of same specification of plain tube.

Q: i'm 15, never had a baby or been pregnant, and i can't use hormonal birth control due to my bipolar disorder. my older sister is also bipolar and has the copper iud, but i havent gathered too many side effects or information on it. help? :): It’s common sense: the healthier you are, the more likely you are to get pregnant. Try to do whatever you can to improve your chances of getting pregnant.

Q: Can‘t be drums or a shoebox guitar but I need something that isn‘t stupid but isnt expencive or require like power tools and stuff. Help.?: Copper pipe organ. Buy copper pipes from Home Depot or other store that sell water pipe. Pick a few in different size or buy a whole 10 feet long pipe then cut it down into different length. One important thing to remember The smallest size and shorter copper pipe generates higher tone. The large size and longer copper pipe generates lower tone. Cut one foot in length to start. Knocking it to check its sound. Make different tones as you wish by cutting more pipes. Hang pipe with a fish line at one end.

Q: Which copper gas pipe does the air conditioner weld?: When the copper tube is red, add the solder. The key is to put the copper red plus solder, it is worth noting that copper can't burn too red, burning too red, silver electrode is added up, more and more will flow below the crater, but above the weld solder less.

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: copper (II) oxide, or cupric oxide, CuO.What is the written balanced chemical equation for this reaction ???: Heating copper metal in oxygen will result in a mixture of both copper(I) oxide, Cu2O and copper (II) oxide, CuO. The higher the temperature, the greater will be the percentage of copper(II) oxide. Upon standing in air, Cu2O will convert to CuO. Therefore, copper(II) oxide is the preferred product. 2Cu(s) + O2(g) --> 2CuO(s)

Q: We're getting a water filter system put in and the plumber is recommending we get rid of the copper supply line and go with PVC. I'm concerned about phthalates in the PVC especially since the water is acidic. (ph of about 6.7) I'd rather not be drinking plastic, so I was wondering should I stay with the copper pipe, go with the PVC, or go with polypropylene pipe such as Aquatherm pipe (aquathermpipe ): I believe the copper will breakdown quicker with the acidic water and old copper may have lead solder. I would say the aquathermpipe is best but PVC would be my choice do to cost and break down composition. your water is acidic but not so that it will do what your brain is telling you acidic means. If this makes sense.

Q: New electrical wiring (in aluminum piping) on the wall passes very close to and crosses heating pipes that are copper. The copper pipes (from the boiler) give out a lot of heat, would that damage or in any way cause problems with the electrical wiring that is in electrical tubing?: If you think the value of a human life is less than an electric cord, then tape away. Replace the damaged cord, or, cut it at the damaged area and replace the the cord cap (plug end) with the proper type. Bring the cord with you to your local hardware store and ask the person in the electrical department which one to use if you're not sure. Don't play Russian Roulette with your or your families safety. Do it right, and sleep tight!

Q: Why does Copper Sulfate help plants to grow? I put Copper Sulfate in a radish seed and 50% of the seed grew but why is this?: Copper sulphate was actually used as a herbicide, used to kill weeds. Copper is needed for many enzymes, but high doses are toxic.

Q: I inherited some copper cookware 20 years ago, is it worth anything?: Not really, plain old copper cookware is very limited. Better cookware sets are made from stainless steel and an alloy, or combination, of different metals that include steel, nickel, and chromium, among others. These other metals basically help in making the steel able to resist corroding. These types of utensils would not require any use of excessive oils and butter to prevent food from sticking.
