I'm assuming you mean house pipe joints. Start at the pipe union, using a bigger pipe wrench if necessary. If the joint breaks you will have to replace the pipe. Unfortunately there aren't any real good tricks, it just takes a lot of force. you can try draining the pipe and adding heat, but don't get it hot enough to melt the galvanized coating otherwise you'll NEVER get the pipe off. If it's a gas pipe don't try putting heat on the line. That wouldn't be good.

A pipe joint is a key component to any successful plumbing system. Pipe joints means the connection at the ends of pipes that ensures tight sealing and strength.
