方管，是方形管材的一種稱呼，也就是邊長相等的的鋼管。是帶鋼經過工藝處理卷制而成。一般是把帶鋼經過拆包，平整，卷曲，焊接形成圓管，那么您知道
濟南方管的加工要注重什么嗎？
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?
方管要在專用進口流水線上進行制作，以確保風管制作精度及方管的密閉性。方管配件的下料應在進口專用機器上運用計算機軟件全自動化完成，并由進口的鈑金專用等離子切割機上完成自動等離子切割工序。方管管體與插接法蘭間的連接應采用無鉚釘連接工藝，運用進口設備進行無鉚釘連接工藝。方管的咬口連接應采用進口自動咬合器進行咬合工藝。
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.
方管的連接法蘭應采用連板法蘭及插接法蘭連接工藝，方管大邊邊長小于或等于2000mm時應采用共板法蘭連接形式。
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.
1、不銹鋼彎頭變壁厚不銹鋼方管，沿管子長度方向使壁厚發生變化；
1. Stainless steel elbow is a stainless steel square pipe with variable wall thickness, which changes the wall thickness along the length of the pipe;
2、加工方管斷面，將圓形斷面變為方形、橢圓形、多邊形；
2. Processing the square pipe section, changing the circular section into square, oval and polygon;
3、帶卷邊和封底類的方管，增加管端總強度向管的外側或內側卷邊或將方管端部封住的方管；
3. For square pipes with curling and back cover, increase the total strength of the pipe end to curl to the outside or inside of the pipe or seal the end of the square pipe;
4、不銹鋼彎頭變直徑方管，指管端或管上某一部分直徑減?。?/div>
4. Stainless steel elbow is a square pipe with variable diameter, which means that the diameter of the pipe end or a part of the pipe decreases;
5、不銹鋼彎頭彎曲方管，我們接觸比較多的，就是將直管變為不同曲率半徑的彎管，如彎頭、彎管等等；
5. Stainless steel elbow bending square pipe, we have more contact with, that is, changing straight pipe into elbow with different radius of curvature, such as elbow, elbow, etc;
6、帶凸緣和圓緣的方管，前者指管子端部向內側或外側凸，后者指在管的圓周方向形成隆起的或凹槽的方管。
6. A square pipe with a flange and a round edge. The former refers to a square pipe whose end is convex to the inside or outside, and the latter refers to a square pipe with a bulge or groove formed in the circumferential direction of the pipe.
