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 just took in 30 lbs of scrap copper and the guy told me they were only paying .95 per lb, does this sound right?: The price of scrap copper along with all other scrap metals has decreased significantly. You did not indictate if the scrap copper was cable, wire, buss bar, stripped cable, etc. therefore it is hard to tell if that is a fair price. If it was cable (not stripped) then that was a fair price. If it was clean copper then that seems low. For current, daily and historical pricing for scrap metals please check the source below

Q:Is there a way to speed up the Patina process (vertigris) on copper?: try liver of sulfur we used it in industrial arts class when I was a kid.

Q:I have a copper IUD the NOVA-T by Bayer.My boyfriend has ejeaculated in me... is that safe ?what are the chances I am pregnant ?I am supposed to get my period in like 3/4 days.This morning I have been throwing up with diarrhea cause i ate some old chickenand i didnt knowPLEASE GIVE ME ALL THE INFO YOU KNOW !& PERSONAL EXPERIENCE: it's possiable, similar to any being pregnant can exhibit a fake bad, I have had 3 ectopic pregnancys and all of mine have confirmed up on a scan even though. Make certain u get checked, an IUD places u at a mild bigger danger for an ectopic, and they're not anything to clutter with! well good fortune

Q:Mainly because of price, and with close relation to its performance (like its material and ability to not get damaged early). Nothing plastic though. I think that‘s what PVC is?: Rob is right. Pex is the new thing. Blue for cold and red for hot water. They are putting it in slab houses here and will withstand freezing and will expand. They are plastic and so is pvc. If you do not like the idea of plastic then you will have to go back with copper.

Q:can i use copper pipe for natural gas?: Hello Balsaxx, There is so much hype regarding natural gas and copper pipes. Just to give you some peace of mind, Many people will say not to connect copper pipes to natural gas, is what they fail to tell you, is that when all houses were built, the original pipe was made from copper, over the years things in the world of construction have changed, they have found new materials to last longer, have found different fluxes applied to the joints on copper pipes to last longer etc etc. I am 100% British, we have houses that are still standing well over 200 years of age, with the addition of gas central heating and modern heating systems. We never use anything but copper for our plumbing, unless the original house was plumbed using lead pipes. I moved to the USA approximately 5 years ago, and am a self employed contractor, we do anything from installing a light fixture to building a dream custom home. Do not get sucked into the false claims that copper will erode and it is a bad thing, Copper is by far the best choice for any plumbing application, and I am positive that when your house was built, the plumbers knew about all the different types of flux. Flux is used to around the joints, to make the soldier run around the joint and create a water tight or gas seal. I have a house that is 140 years old here, all the pipes are copper and the water is supplied from a well, I have a gas furnace and all the pipes are fine, the well water does build up sediment in the pipes, and one of my bathrooms has a shower which is a bit slow, the water pipes/copper pipes connecting the shower is original I.E. 140 years of age. There are too many people hearing horror stories about copper and gas, copper and water etc. You have nothing to worry about, and if you out live your house than maybe consider a change in about 200 years lol. I hope this gives you peace of mind and do not worry. Paul M

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:Ok, I've been told that you can tell if red residue on your gun's bolt is rust or copper by taking a copper solvent-sprayed cloth and running it through. And that rust will stain the cloth red and copper will stain the cloth blue/green. What does it mean if the cloth turned black? Or comes out clean? The bolt still has red tinge to it.-- I use Remington Britebore.: What gun? Can't you people learn to ask a thorough question? I don't understand running it through. Are you trying to clean the inside of the bolt? I doubt you will have copper on the bolt, you will have copper fouling inside the barrel. Whatever is on the bolt will be rust or accumulated crud. If the cloth turns black it means it was dirty. If the cloth comes out clean it means it was not dirty. If the red tinge on your bolt will not clean off it probably is rust. Try 0000 steel wool and BreakFree.

Q:I heard this term today, but don‘t know what it refers to when they talk about sweat? Any help or explainations appriciated!Also, what is Schedule 80/ schedule 40 does that refer to a certain kind of pipe?: No chance to put a bit of air in it with a compressor? It shouldn't do serious damage but it is better if you can avoid rolling it while completely flat.

Q:A box contains a mixture of small copper spheres and small lead spheres. The total volume of both metals is measured by the displacement of water to be 417cm3 and the total mass is 4.40kg . What percentage of the spheres are copper?I keep getting 32.9% but that is wrong.: Density pure copper is 8.96 grams/cm3 Density of pure lead is 11.4 grams/cm3 Average density of the lead and copper balls above is 4400 grams over 417 cm3 = 10.55 grams/cm3. Let X = the decimal fraction of lead in the mixture and l.0 minus X = the decimal fraction of copper.in the mixture ll.4 g/cm3 (X) plus (1.0 minus X)(8.96 grams/cm3)= 10.55 grams average density 11.4 x plus 8.96 minus 8.96X = 10.55 2.44 x + 8.96 = 10.55 2.44 X = l.59 X = 1.59 over 2.44 which = .65 or 65% lead and l00% minus 65% = 35% copper. 1

Q:So I have naturally dark brown hair.My mom had been bugging me to go blonde for like three years, so I finally caved.It turned out a really light copper, like a penny but a few shades lighter. It almost looks pinkish, lol. I CAN'T go to a hair salon to fix this, so don't suggest that unless you'd like to pay for it, haha. What kind of toner should I buy? Or do I just buy another box of dye to fix this? Thank you. :): you shoulda used a prelightener first, altho the prelightener would bring you to the stage your hair is at now. so i would say put another dye in, but be careful you can damage your hair, the lighter the colour you got the weaker and more brittle your hair becomes. use a good treatment. the reason your hair went copper was because it was so dark in the first stage, the natural steps your hair will go during lightening is ....brown, red, orange/copper,blonde, white, and then disintergration. so as i said be careful doing it yourself its tricky going blonde and getting the right shade you don't want copper but you dont want white or even worse for your hair to fall out. blonde has lot of up keep aswell, roots! sorry but you shouldn't of listened to your mam, maybe you shoulda went for a few highlights!
