How are metal shower drains made?

Many of the 3D drains with the integrated plugs are also cast out of steel or aluminum, which allows a greater strength part because of the different thicknesses.  Also, in the past some of these were forged but that process tends to be expensive and is therefore not often used any more

1- Take their deodorant and roll it up, cut half of it off then roll it back down, fill it up with cream cheese. Remember to round off the top to make it look normal. \n2-If your sink has a spray nozzle then use a rubber band and strap the handle down then point the sprayer in the direction where they will be standing. When they turn on the faucet they will get soaked.

So much to say...  There is a good possibility that these worms are not coming from a person using the shower, but live in or around the shower themselves.  Unless you are using your shower as a toilet, intestinal worms shouldn't show up in the shower.  There is a group of insects called drain flies that specialize in shower and sink drains.  They are harmless and should go away if you keep your drains clean.  They look like small dark sort of fuzzy worms with dark head capsules.  The adults are small, light grey with broad wings that end in a point. They are very fuzzy and are sometimes called moth flies.  I think they're cute.  Here's a link to a picture of an adult: http://images.google.com/imgres?imgurl=http://www.ento.psu.edu/ImageGallery/HouseMisc/Thumbs/Drain-fly03%2520Psychoda%2520lar117.jpg&imgrefurl=http://www.ento.psu.edu/ImageGallery/HouseMisc-2.htm&h=47&w=112&sz=4&tbnid=TMswDgiCpWjSLM:&tbnh=33&tbnw=81&hl=en&ei=ZiSMRPrzHI-SaeODwZMK&sig2=fHNR_-1ZtGtltcYvlFMWFA&start=1&prev=/images%3Fq%3Ddrain%2Bfly%2Blarva*%26svnum%3D10%26hl%3Den%26lr%3D%26client%3Dsafari%26rls%3Den-us%26sa%3DN

Are you talking about sealing surfaces or welded connections?\n\nFor sealing surfaces you have raised face flanges that can use a flat gasket or a spiral wound gasket. There are  flanges with grooved faces that use a soft oval shaped iron ring. These are usually just called ring joint flanges. Tongue and groove flanges are also available.You can also get flat faced flanges (typically for water and other low pressure services) that can use a rubber or asbestos like gasket.\n\nThe connection of the flange to the pipe can be butt weld, socket weld, slipon, or threaded.

What are you wanting to find here? If you need to know what diameter drain you need for new construction, it depends on what your fixture load is going to be. A 2" drain pipe can handle 21 to 26 fixture units, which would handle most homes and small offices.

Put two rollers on tracks near the end of the mop handle and put a compression spring in between them, then add a rac-and-pinion system to shove the rollers along, the spring will keep them together and the water will be shoved out.

i think your talking about copper plating which is done by adding an electrical charge to the metal and the copper somehow clings to the metal

You need two different kinds of metal. Copper is easy for one. The other can be almost any non-copper metal. Simple trial and error should show you a good choice. \n\nTry: nails, silverware, pointy tools (screwdrivers), bits of metal from craft or hobby jobs, coat hangers, etc. You can even jam coins in there!

You need a solution of gold sulfate or gold chloride to do it, but it has to be extremely pure, made with distilled/deionized water.  Remember to have your ring on the anion (the negative) and your gold source on the cation.

It is called a wet lining where the refractory is cooled on the outside metal shell by water. You need a good designer to make it happen but there is nothing to beat it.
