发明名称 Outer diameter pipe plug
摘要 An outer diameter plug is provided for sealing the open end of a pipe. The plug is capable of being reused on a range of pipe outer diameter tolerances and of providing effective fluid-tight sealing over a range of internal pressures. The plug is particularly suited for use in pressure testing pipes by means of pressure fluids admitted to the pipes through the plug.
