作為一個生產方管的廠家要對方管的各個工藝流程、鋼管材質性能有足夠的掌握，在客戶訂購焊管的時候方管和矩形管是客戶的選擇對象。我們多次提到方管和矩形管的優劣，方管在生產過程中只有管端的尺寸是最嚴格的的，畢竟方管不同于矩形管，所以在生產方管的時候要注意把口徑和管端做到最好，以便于在安裝焊接過程中能夠方便快捷的施工。對于生產大口徑鋼管壁厚較薄的鋼管的時候要注意加固或者對鋼管做支架，以防止方管在運輸過程中出現橢圓或口徑變形。對于方管來說口徑的準確尺寸是最重要的，其次要注意的是方管焊口不要咬邊，要把卷制好的鋼管的兩個焊邊對齊對平，焊接出來的鋼管才能漂亮、規范。其次要注意的是方管的直度，方管的直度不但影響方管整體的外觀最主要的是影響后期施工焊接。

As a manufacturer of square pipe, we should have a good command of each process and material properties of square pipe. When customers order welded pipe, square pipe and rectangular pipe are the customers'choices. We have repeatedly mentioned the merits and demerits of square and rectangular pipes. In the production process, only the pipe end size is the most stringent. After all, square pipes are different from rectangular pipes. Therefore, we should pay attention to the best caliber and pipe end when producing square pipes so as to facilitate the installation and welding process. For the production of large diameter steel pipe with thinner wall thickness, attention should be paid to strengthening or bracketing steel pipe to prevent ellipse or caliber deformation of square pipe during transportation. For square pipe, the exact size of the caliber is the most important. Next, we should pay attention to the square pipe weld without undercutting. We should align the two weld edges of the rolled steel pipe, so that the welded steel pipe can be beautiful and standard. Secondly, attention should be paid to the straightness of square pipes. The straightness of square pipes not only affects the overall appearance of square pipes, but also affects the later construction welding.
