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 know they are for refrigerators and air conditioners for now but I want to know more about brass information, I encountered this difficult because I now faces a test if I am going to leave after this will be able to enter this field work if a wrong words, so I want to ask know friends to help, thank you.: Application and development of ACR copper tube in air conditioning heat exchangerDu Xuefeng, Zhang Xiaochun, Wang Yankun, Li JinweiAbstract: This paper introduces the ACR tube heat exchanger in air conditioning, and the causes of the evaporator and heat exchanger with copper in the process of easy problems, principle and manufacturing technology of high cleanliness and high efficiency tube tube on behalf of the development direction of future rifled tubes are discussed.Key words: air conditioning; heat exchanger; internal screw copper tube; energy efficiency ratio; tooth profile

Q: I‘m having a solar thermal system installed in my home. It is an old home and the contractor has to run the piping up the side of the wall in my kitchen (w/ insulation 2 total diameter). In their contract the covering of this pipe is clearly outside the scope. How would you suggest I hide this pipe?: A good contractor would run the pipe inside the wall unless I am missing something.

Q: Please can you give me some copper compounds with a brief description of what their uses are or something. Or a link to a website with info?Thanks. :): %Cu = zero.545/two.14 = 25.forty seven% one million mole of Cu has a molar mass of sixty three.546 sixty three.546 = zero.2547 x Molar Mass of Compound Molar Mass = 249.two Compound perhaps CuSO4.5H2O (Molar Mass =249.7)

Q: how to c;ean the blue /green gunk from my bath tub due coming from the copper pipe. It like glue .: Rotate and balance your tires every other oil change.

Q: what is a wall thicknes of 1/8 copper pipe to carry liquid CO2. Does ACR pipes, which are sold at stores, meet requirements ?: Typical wall thicknesses are 0.065 and 0.049. Conceptually, this would be fine for carrying liquid CO2. However, for that small of a tube, you need to make sure it is very well insulated. Otherwise, you're going to have a lot of vaporizing and just end up with CO2 gas. I'm assuming you're doing this at relatively lower pressures. For these wall sizes, the pressure limit is 2400 psi for the 0.049 wall and 3200 psi for the 0.065 wall.

Q: Which is good for cutting copper tubes?: The brass cutting recommended Shanghai high volatile, high volatile Shanghai decoration materials Co., Ltd. specializing in the production of sales of metal processing, laser cutting, shearing, bending, slotting and other metal materials, good products and professional sales and technical team, to provide quality products and satisfactory service to customers, the company is willing to work with all partners. With the progress of sharing, outstanding future!

Q: I like all the compounds of Copper (Except the really poisonus ones lol) but I was wandering if anyone knew how to produce some of these compounds. If it is reacting the acid with the metal can someone tell me how to get rid of the remaing acid while producing the compound. (Please no safety warnings): The place to start is reaction of copper metal with nitric acid. This produces copper(II) nitrate. Crystallize the finished product from water. This gets rid of excess HNO3. Add Na2CO3 to a water solution to produce basic copper carbonate [CuCO3*Cu(OH)2]. Add various acids to this to make cupric acetate, copper sulfate, etc. Finally, add concentrated ammonia to a CuSO4 solution and evaporate and crystallize an electric blue preparation of Cu(NH3)4++SO4=.

Q: Is there an adaptor you can buy that joins old lead water pipe to copper pipe? Also is this a diy job?: It can be a DIY job. What you need to do is to get a rubber boot with two hose clamps on it and attach one end to the lead and the other to the copper. However, if this is on the water supply to the house, I would rip out the lead and go copper all the way - that might not be a DIY job.

Q: Does anyone know if Great Stuff spray foam insulation is ok to put around copper heating pipes?: If you spray only enough foam so that when it has finished expanding it fill the small gap in the wallboard or baseboard molding, then there is no problem. On the other hand, if you were to pump a half can or more into the wall cavity it is possible that in expanding it could crack your drywall or plaster. As far as the foam creating any hazardous condition, I don't believe so.

Q: ok in my Phisical Science class to day we had a lab, the teacher had a copper ball that he put in a bowl of water and the copper ball was floating in it. then he heated up the water and the copper ball sank to the bottome of the bowl.the starting tep. for the water befor it was heated up was 20 degrees C and when it sank it was 79 degrees C. can anybody tell me why this happend i have a general idea of why it happend but i am not shure.: The okorder
