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 base pipes are galvanized pipes, which follow the mature connection mode of the galvanized pipe: 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), suitable for 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, the application of DN100 above, the implementation of the 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 the situation, generally DN100 or more used, flange, etc. by the manufacturer customized, and the connection with a 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 joints, according to the actual working conditions using welding, the implementation of YB/T5092-2005 and JB/T4747-2002 standards, the general use of three-layer welding, argon arc welding first, then welding the transition layer, finally manual arc welding filling the cover. |
