02

Good smoothness

The surface of cold-rolled tube is smooth and has no oxide layer, making it less prone to corrosion and other problems. Its surface quality is better than that of ordinary steel pipes. Cold-rolled tube are usually used where corrosion resistance is required, such as in chemical and petroleum industries.

03

Mechanical properties

Because cold-rolled tube have been processed through multiple processes, their tensile strength and yield point are high, and their impact toughness is poor. Therefore, cold-rolled tube are usually used where high strength and hardness are required, such as machinery manufacturing, building structures and other industries.

FAQ

 

Q: What is cold rolled pipe?

A: Cold-rolled seamless pipe refers to a steel plate or steel strip processed into various types of steel by cold drawing, cold bending, cold drawing and other cold processing at room temperature.

Q: What is the difference between hot rolled and cold rolled tubes?

A: Cold rolled steel is essentially hot rolled steel that has been further processed by being allowed to cool at room temperature and annealed or temper rolled. Cold rolling produces steel with closer dimensional tolerances and a wider range of surface finishes than hot rolling.

Q: Is cold-rolled stronger?

A: In terms of physical characteristics, cold rolled steels are typically harder and stronger than standard hot rolled steels. As the metal is shaped at the lower temperatures, the steel's hardness, resistance against tension breaking, and resistance against deformation are all increased due to work hardening.

Q: Does cold rolling increase density?

A: It can be observed that as cold rolling reduction increases, the grains begin to elongate along the rolling direction and continuously fragment. Additionally, the kam values within the grains gradually rise, indicating an increase in dislocation density within the cold-deformed material.

Q: Is there a limit to cold rolling?

A: However, cold rolling does come with certain limitations. For instance, metals like aluminum and copper require annealing before cold rolling to prevent cracking due to internal stresses. The process also subjects parts to wear on tools, which can necessitate frequent maintenance or replacement to ensure quality.
