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、切断的位置，要配合施工图及现场的状况，用米尺或其它测定工具，画出确定位置并标示切断线。

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、切断时，请用虎头钳等方管固定器具，确实固定后再行切割。

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、要切断的地方，请用抹布或柔软的布类将方管表面的油、杂物或泥土完全擦拭干净。

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、一定要选择方管切断专用。

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

5、方管的切断面应保持真圆，切断线应与方管轴心成直角。用力过猛是导致将方管切成扁平或椭圆的原因，故应以适当的力量切方管。

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、切断面的铁屑、毛边应用锉刀或适当工具完全清除，以防铁屑、毛边在插入接头另件时刮伤橡胶o型密封圈及其它附属品。

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.
