| 双金属的连接方式： The connection mode of bimetallic: 外基管多数采用的是镀锌管，沿用了镀锌管成熟的连接方式： Most of the outer tubes are galvanized pipes, and the galvanized pipes are used as mature connections. 1、螺纹连接（俗称丝扣连接），适用于DN15-DN100，执行GB7306-2和GB3287-1982标准； 1, threaded connection (commonly known as threaded connection), applicable to DN15-DN100, the implementation of GB7306-2 and GB3287-1982 standards; 2、沟槽卡箍连接，适用DN100以上，执行CJ/T156标准； 2, groove clamp connection, applicable to DN100 or above, execute CJ/T156 standard; 3、法兰连接，视情况而定，一般DN100以上采用，法兰等由厂家定做，并在连接处配上专用硅胶层； 3, flange connection, depending on circumstances, generally DN100 above, flange and other manufacturers customized, and at the junction with special silica gel layer; 4、焊接连接，据实际工况采用焊接，执行YB/T5092-2005和JB/T4747-2002标准，一般采用三层焊，先氩弧焊封底，再焊过渡层，最后手工电弧焊填充盖面。 4, welding connection, according to the actual working conditions, the use of welding, the implementation of YB/T5092-2005 and JB/T4747-2002 standards, generally used three layers of welding, first argon arc welding bottom, then welding transition layer, and finally manual arc welding filling cover surface. |
