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 want to know how much do the scrap copper, nickel buyers buy for 1g r o 1 kg?: Copper is currently trading on the LME for US$7.502/kg, so that would be 0.75 cents per gram.

Q:I know someone who thinks it‘s fine to throw some gunk on the leaky spot and then wrap it in duct tape? That doesn‘t seem very secure to me. What do you think?: Are we talking a copper pipe with pressurized water, or a plastic drain pipe? If copper, then it needs to be replaced ASAP; unless you have experience with pipe soldering and fitting, call a plumber. If a plastic drain pipe: First see if its leaking at the joints. Sometimes you can tighten it by hand. If its an actual hole in the pipe, you can remove it by hand, take it to Lowe's or Home Depot and ask for a replacement part just like it. Good luck

Q:I‘m thinking of trying to get the angelfish to lay eggs on it.: copper will kill your fish, even as small an amount as a penny. When I was young, I had a fresh water 10 gallon tank with guppies, and it did very well, that is until my brother thought a penny would be pretty in it, I soon started loosing my fish left and right.

Q:why cant i fit my 1/4 inch compression valve onto my 1/4 copper water line? Please help?: The iron may melt the decorations on your shirt. It's better to just iron around the edges as best you can, and not over the decorations themselves.

Q:My mom just bought a home that was built in 1847. It has 4 beautiful fireplaces and they have decorative copper frames around the fireplace opening. The only way I know these are copper is because there is the smallest hint of copper shining through 150 years worth of crap. I tried rubbing diluted lemon juice on it but that didn't work. Any suggestions?: Copper Fireplace

Q:What's the positive and negative tolerance of the inside and outside diameter of the copper tube? For example, the diameter is 22, the diameter is 16, diameter 6 state how much their tolerance range? The state copper production enterprises is what type of business? How much is the sampling rate specified in the GB/T2828? How much is the screw nut of the sampling rate? Please enlighten master who I would be grateful!: Different copper tube standards, with different thickness and specifications of copper tube. The specifications of copper tubes include the thickness, length and length of the copper tubes. Purple copper tube thickness: general copper tube in engineering for water cooling more, need to consider the main water pressure, thermal properties. But the tolerance range will not be more than 0.5 millimeters, the inner and outer diameter of the copper tube is 1 millimeters.The characteristics of copper tube: light weight, good thermal conductivity, low temperature strength. Often used in manufacturing heat exchangers (e.g. condensers, etc.). It is also used for assembly of cryogenic pipes in oxygen making equipment. A brass tube of small diameter; used to transport pressure liquids (e.g., lubrication systems, oil pressure systems, etc.) and measuring tubes used as gauges.The copper pipe has a strong corrosion resistance, and has become the first choice for modern contractors in the installation of plumbing, heating and cooling pipes in all residential commercial premises.

Q:Woodwind and brass instruments, how to distinguish?: Woodwind: Piccolo, flute, clarinet, Oboe, Sax etc..Brass: horn, trumpet, trombone, tuba, euphonium, Su Safeng (a large for marching band)String instruments: all violins (small, medium, large, bass).Distinguish between copper and wood in the Western musical instrument body material (not care if it is, the clarinet non copper non wood can't block the). But a part of the material, all pipe mouthpiece section is flat, and wooden or bamboo flute whistle piece in head vocal musical instrument called woodwind instruments. There are two special cases of flute and piccolo, flute is full of metal pipe, nor reed mouthpiece, piccolo glial tube, however, because in the improvement of musical instrument before, in ancient Europe, they are all wooden structure, so respect the tradition, divided into the woodwind group.Who is the mouthpiece section hemispherical metal mouthpiece instrument, divided into copper group.Therefore, how to put it plainly, the brass and the woodwind, see a little bit of a pipe body, and Never mind, even if Sax is copper, still is a Woodwind Group, even the gold flute, still is a woodwind group.There is a very simple distinction method, usually called "XX" instruments are brass, no "No." word, is generally the woodwind group.In addition to copper woodwind and string, western music and a group of percussion instruments, is at the back of the band. The drum cymbals like ah, those were good.

Q:im a little perplexed on my homework for tonight.. the question isWhat value might there be in being able to remove copper from substances? Leaving it alone by itself?what are some ideas?: electronic circuit boards are sheets of phenolic resin coated with a layer of copper foil. a circuit pattern is drawn on the foil with a etch resist pen to protect the trace that is being designed. several different chemical substances are used to etched to the copper away, leaving the design in the board, and producing a prototype for electronic circuits. the chemicals are : ferric chloride, sodium persulfate, and ammonium persulfate. this circuit etching demonstrates the benefits of selectively removing and not removing the copper via the etching process. note: i read the question in more general terms. sounded like the questioner was asking in terms of common industrial usage rather than research terms.

Q:I decided that i want to invest in copper.i have looked around alot but havent found many sellers. i looked at okorder and the prices are horrible! someone is selling a 3 kilo copper bar for $140.00 :( If you know any good copper bullion sellers list their website below. ty: You okorder

Q:Some say, 16 and 6, and some say 16 and 10, and I do not know which one to sell: 16/6 for refrigerators, 16/10 for hot and cold air conditioners.The copper pipe combines the advantages of metal pipe and nonmetal pipe. It is hard plastic pipe, high strength with metal (steel cold drawn tubes with same intensity of wall thickness; equivalent) it is generally flexible metal, and good toughness, with anti vibration, impact resistance and frost resistance performance.
