In the cutting of square tubes, uneven, deformed, and cracked incisions often occur. How can we solve the problems that occur when cutting square tubes? Here are the 6 precautions provided by Tianjin Square Tube Factory to help you solve the problem.

1、切斷的位置，要配合施工圖及現場的狀況，用米尺或其它測定工具，畫出確定位置并標示切斷線。

1. The cutting position should be determined by using a meter ruler or other measuring tools in conjunction with the construction drawings and the site conditions, and the cutting line should be marked.

2、切斷時，請用虎頭鉗等方管固定器具，確實固定后再行切割。

2. When cutting, please use a vise or other square tube to fix the tool, and then cut it after it is firmly fixed.

3、要切斷的地方，請用抹布或柔軟的布類將方管表面的油、雜物或泥土完全擦拭干凈。

3. To cut off the area, please use a cloth or soft cloth to completely wipe off the oil, debris, or soil on the surface of the square tube.

4、一定要選擇方管切斷專用。

4. Be sure to choose a dedicated square tube for cutting.

5、方管的切斷面應保持真圓，切斷線應與方管軸心成直角。用力過猛是導致將方管切成扁平或橢圓的原因，故應以適當的力量切方管。

5. The cutting surface of the square tube should be kept true circle, and the cutting line should be at right angles to the axis of the square tube. Excessive force is the reason for cutting the square tube into flat or elliptical shapes, so appropriate force should be used to cut the square tube.

6、切斷面的鐵屑、毛邊應用銼刀或適當工具完全清除，以防鐵屑、毛邊在插入接頭另件時刮傷橡膠o型密封圈及其它附屬品。

6. The iron filings and burrs on the cut section should be completely removed with a file or appropriate tool to prevent them from scratching the rubber O-ring and other accessories when inserting into the joint.
