What Are The Effects Of Inferior Tube Billet On Seamless Steel Pipe?

The advantages and disadvantages of the billet have a vital impact on the quality of seamless steel pipe. Can produce high quality seamless steel pipe, the billet plays a fundamental role, poor quality billet is prone to produce many quality problems, the following are the main factors of the billet on the quality of seamless steel pipe:

1. Chemical composition: The chemical composition of the billet has a great influence on the quality of seamless steel pipe. If the chemical composition does not meet the requirements, the seamless steel pipe may have insufficient toughness, insufficient strength, brittle and other problems.

2. Internal organization: The internal organization of the billet also has a great influence on the quality of the seamless steel pipe. If the internal organization is not uniform or there are problems such as shrinkage and looseness, the seamless steel pipe may have insufficient strength and be easily deformed.

3. Surface quality: The surface quality of the billet also has a great influence on the quality of the seamless steel pipe. If there are cracks, slag, porosity and other problems on the surface, the seamless steel pipe may have insufficient strength, easy to corrode and so on.

4. Dimensional accuracy: The dimensional accuracy of the billet also has a great influence on the quality of the seamless steel pipe. If the dimensional accuracy does not meet the requirements, the seamless steel pipe may have leakage seams, uneven wall thickness and other problems.

Therefore, in the production of seamless steel pipe, it is necessary to carry out strict inspection and control of the billet to ensure that it meets the quality and process requirements. At the same time, unqualified billets should be disposed of and improved in a timely manner to avoid adverse effects on the quality of seamless steel pipes.
