Poppet valve would be your likely answer.\n\nCheck valve is also acceptable.

This is either a pipe or tube (i.e. muffler pipe for your automtoive is made this way) that has ben bend from flat metal into a tube shape and then welded together to form a solid pipe/tube.\n\nA good explanation can be found at:\nhttp://www.thefabricator.com/ResistanceWelding/ResistanceWelding_Article.cfm?ID=89\n\n\nOther sites that will give more inforamtion:\nhttp://files.aws.org/wj/supplement/01-2004-CHOI-s.pdf\nhttp://www.usstubular.com/facilities/erw.htm\nhttp://www.lbfoster.com/piling/pipepile.html\nhttp://www.weldingengineer.com/1%20Resistance.htm\nhttp://www.ipsco.com/Products/TubularProductManual/TubularProductManualERWIntro.pdf\nhttp://www.phamitech.com/pd_tubemill.htm\n\n\nHope that you find these sites useful.\n\nGood Luck.

Aplly the following formula:\n\nG = w * A, where:\n\nG - flow rate [m^3/s]\nw - speed of fluid [m/s]\nA - transversal section area of the pipe [m^2]

Your problem can not be solved accurately unless you also state the length and roughness of the pipe.  Picture two pipes, one ten feet long and the other the length of a football field.  Clearly the longer pipe will greatly resist flow.  Also a smooth copper pipe will resist flow less than a rusty rough one.  The Crane company published a book that can be used to estimate flow through pipes based on lab tests.  Good luck.

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.
