The utility model provides a metal pipeline prevents static cross -over connection device, including cross -over connection band steel, jumper wire, copper binding post, bolt, nut, gasket, cross -over connection band steel lower part is the stiff end, and upper portion is the link, the stiff end welding adopts thermofussion welding or argon arc to weld on the metal pipeline outer wall, the link trompil is connected with copper binding post through bolt, nut, gasket, copper binding post and the crimping of jumper wire soldering. The utility model provides a prevent static cross -over connection device, static reaches equipotential purpose through cross -over connection band steel, jumper wire circulation. The size of cross -over connection band steel can be adjusted according to the insulation layer thickness of pipeline, and the length of jumper wire can be adjusted according to the actual range of cross -over connection, has improved the adaptability of preventing the static cross -over connection. Simultaneously not only confining the flange to and preventing the static cross -over connection, what can expand to pipe -line equipment such as valve prevents static cross -over connection mode, is the brand -new metal pipeline prevents static cross -over connection device that multipurpose, suitability are strong.
