方管，是方形管材的一种称呼，也就是边长相等的的钢管。是带钢经过工艺处理卷制而成。一般是把带钢经过拆包，平整，卷曲，焊接形成圆管，那么您知道
济南方管的加工要注重什么吗？
Square pipe is a name for square pipe, that is, steel pipe with equal side length. It is made of rolled strip steel after process treatment. Generally, the strip steel is unpacked, leveled, crimped and welded to form a round pipe. Do you know what to pay attention to in the processing of square pipes in Jinan?
方管要在专用进口流水线上进行制作，以确保风管制作精度及方管的密闭性。方管配件的下料应在进口专用机器上运用计算机软件全自动化完成，并由进口的钣金专用等离子切割机上完成自动等离子切割工序。方管管体与插接法兰间的连接应采用无铆钉连接工艺，运用进口设备进行无铆钉连接工艺。方管的咬口连接应采用进口自动咬合器进行咬合工艺。
The square pipe shall be manufactured on the special imported assembly line to ensure the manufacturing accuracy of the air pipe and the tightness of the square pipe. The blanking of square pipe fittings shall be fully automated by using computer software on the imported special machine, and the automatic plasma cutting process shall be completed by the imported special plasma cutting machine for sheet metal. The connection between the square pipe body and the plug-in flange shall adopt the rivetless connection process, and the imported equipment shall be used for the rivetless connection process. The bite connection of square pipe shall adopt imported automatic bite device for bite process.
方管的连接法兰应采用连板法兰及插接法兰连接工艺，方管大边边长小于或等于2000mm时应采用共板法兰连接形式。
The connecting flange of the square pipe shall adopt the connection process of connecting plate flange and plug-in flange. When the length of the large side of the square pipe is less than or equal to 2000mm, the common plate flange connection shall be adopted.
