Letter Re: Stocking up on Copper Tubing/Pipe

Wednesday, Apr 19, 2006

I have been following the metal’ and copper in particular, as it is a very necessary part of our modern existence.
One of the things I envision, is a shortage of copper tubing. I have been buying a little extra every time I go to the home store. Some of it I plan use for making a still-- for making alcohol, other sizes are for my propane tanks and last but not least, I still have copper [water] pipes in my house that are going on 30 years old, so I have been buying some to replace that.
What is strange, is that copper tubing has almost doubled in prince in the last two years, and they say it’s because of China buying most of the worlds production for electronics and other stuff. Not sure, but I have been getting a good replacement stock of the tubing.
BTW there are several different grades of tubing and you need to be buying the K grade as it is thicker walled, and approved for propane. The M grade is not approved for propane, as it has thinner walls. The K grade bends easily without kinking, and the M grade will not bend [properly] at all. Most of the solder-on fittings are for the M grade and the compression type and flare fittings are for K tubing. - Mel
