What is the thread of the pipe?

　　What is the thread of the pipe? Also called screw thread connection, it is through the internal and external threaded pipes and pipes and valves connected. This connection is mainly used for steel, brass and high pressure connection, threaded pipe welding at present most of the use of thread machine operation, and for the thread machining accuracy and surface roughness requirements are very high pressure pipeline must lathe.
