Different from cold pull -out seamless pipes and hot -rolled seamless pipes

On the other hand, hot-rolled seamless pipes are manufactured by heating a solid metal billet to a high temperature and then rolling it into a seamless tube. This process results in pipes that have a rougher surface finish compared to cold pull-out pipes. However, hot-rolled seamless pipes are known for their superior strength and durability. They are commonly used in applications where high temperature and pressure resistance are required, such as in the oil and gas industry.

Cold pull-out seamless pipes and hot-rolled seamless pipes are two different types of seamless pipes that are used in various industrial applications. While they may seem similar in terms of their purpose, they differ in the way they are manufactured and the properties they possess.
Cold pull-out seamless pipes are manufactured by pulling a solid metal bar through a die to create a hollow tube. This process is done at room temperature, hence the term "cold pull-out". This method results in pipes that have a smooth surface finish and tight dimensional tolerances. Cold pull-out seamless pipes are known for their high precision and excellent mechanical properties. They are commonly used in applications where a high level of accuracy and consistency is required, such as in the automotive and aerospace industries.
On the other hand, hot-rolled seamless pipes are manufactured by heating a solid metal billet to a high temperature and then rolling it into a seamless tube. This process results in pipes that have a rougher surface finish compared to cold pull-out pipes. However, hot-rolled seamless pipes are known for their superior strength and durability. They are commonly used in applications where high temperature and pressure resistance are required, such as in the oil and gas industry.
In terms of properties, cold pull-out seamless pipes have a higher dimensional accuracy and smoother surface finish compared to hot-rolled seamless pipes. This makes them more suitable for applications where a high level of precision is needed. On the other hand, hot-rolled seamless pipes have superior strength and toughness, making them ideal for applications where high temperature and pressure resistance are critical.
In conclusion, cold pull-out seamless pipes and hot-rolled seamless pipes are two different types of seamless pipes that are used in various industrial applications. While cold pull-out pipes are known for their high precision and smooth surface finish, hot-rolled pipes are valued for their superior strength and durability. The choice between the two types of pipes depends on the specific requirements of the application and the properties desired.
