The Difference Between Cold Drawn and Hot Rolled Tubes
1. Processing Method
From the processing point of view, hot-rolled tubes are made by hot processing, while cold-drawn tubes are made by cold processing. Hot rolling is rolling at a temperature higher than the recrystallization temperature, and cold rolling is rolling at a temperature lower than the recrystallization temperature. Therefore, they are processed differently from each other.
Hot rolled steel pipe is used for fluid transportation, mechanical structures, and other occasions with low dimensional requirements. And cold rolled steel pipe is generally used for equipment, hydraulic systems, pneumatic, and other demanding occasions.
The manufacturing process of cold drawn tubes is more complex than that of hot rolled tubes. Cold drawn tubes are rolled several times, while hot-rolled tubes are much simpler to manufacture. Therefore, the price of cold-drawn tubes is relatively high. According to the price in the market, the price of hot-rolled steel pipe is about 30-75 USD per ton lower than that of cold-drawn pipe.
Hot rolled steel pipes are usually of large diameter, while cold rolled steel pipes are usually of small diameter. The former usually has an outside diameter greater than 32mm and a wall thickness of 2.5 to 75mm, while the latter can reach a diameter of 6mm and a wall thickness of 0.25mm. you can choose according to the specific size required for your project.
The surface of cold rolled pipe is bright and the size of the caliber is smaller than that of hot-rolled seamless steel pipe. The caliber of hot rolled steel pipe is larger than that of cold rolled seamless steel pipe, and the surface has obvious scales or red rust. Generally speaking, the surface finish of cold rolled pipe is much better than that of hot-rolled pipe.
