How to avoid scratches on seamless tubes?

Reasons for scratches on seamless tubes:

During the production, transportation and use of seamless tubes, they are prone to scratches due to various reasons. The main reasons are:

1. Process problems in the production process: If the rolling and cutting of steel pipes do not meet the technical standards, it is easy to cause surface scratches.
2. Damage during transportation: During transportation, seamless tubes may be subjected to excessive surface force and scratches due to improper operations such as lifting and stacking.

3. Wear during use: If seamless tubes frequently come into contact with other hard objects during use, surface wear and scratches are likely to occur.

Preventive measures to avoid scratches on seamless tubes:

In order to avoid scratches on seamless tubes, we can start from the following aspects:

1. Strengthen the management of the production process: Improve the processing quality of steel pipes, reduce cutting and rolling errors during the process, and ensure that the surface of seamless steel pipes is smooth and not prone to scratches.

2. Strengthen the management of the transportation process: When transporting steel pipes, pay attention to the methods of lifting and stacking to avoid pressure and wear on the surface of the steel pipes.

3. Use appropriate transportation tools and fixing measures: Special steel pipe transportation vehicles or skids, rubber pads, etc. should be used for fixing to prevent seamless pipes from rolling or colliding with each other during transportation and causing damage to the pipe body.

4. Avoid direct contact with sharp objects: During loading and unloading, load and unload gently. It is strictly forbidden to throw, roll and drag seamless pipes to prevent the surface of the pipe from being scratched or causing defects such as local depression of the pipe wall. During the use of seamless steel pipes, avoid contact with other hard objects to reduce surface wear and scratches.

5. Reasonable planning of loading and fixing methods: Before loading, the placement of the goods should be reasonably planned, and the center of gravity should be stable. Appropriate fixing measures, such as ropes and brackets, should be selected to stabilize the seamless steel pipes on the transportation tools to avoid sliding or collision.

6. Choose a flat and wide road: When planning the transportation route, a flat and wide road should be selected to reduce bumps and vibrations during transportation and avoid scratches caused by uneven roads.

7. Avoid direct contact with the ground: When storing, the seamless pipe should be placed overhead to avoid direct contact with the ground to prevent rust and scratches.

8. Add protective measures: A protective sleeve or coating can be used on the surface of the steel pipe to increase the surface hardness and wear resistance, effectively preventing scratches.

In short, seamless tube scratches are a common quality problem. Through the above measures, seamless tubes can be effectively prevented from being scratched during production, transportation, and use, ensuring their surface integrity and service life.
