The difference between hot rolled seamless steel tubes and cold rolled seamless steel tubes

What is the difference between hot-rolled seamless steel tubes and cold-rolled seamless steel tubes? Is it generally said that seamless steel tubes are not hot-rolled seamless steel tubes?
Cold-rolled seamless steel tubes are often of small diameter, and hot-rolled seamless steel tubes are often large diameter. The precision of cold rolled seamless steel tubes is higher than that of hot rolled seamless steel tubes, and the price is also higher than that of hot rolled seamless steel tubes.
Seamless steel pipe: Because of its different manufacturing processes, it is divided into hot rolled seamless steel pipe and cold drawn seamless steel pipe.

Waste Gasification is the process of sorting, dewatering and pyrolysis gasification of solid waste. Msw Gasification is a process of volume reduction. The gasified waste can be decomposed into various combustible gases. However, the composition of this combustible gas is complex and can not be directly discharged. Therefore, secondary treatment is needed to further purify the tail gas. Waste gasification is a kind of environmental protection waste gasification equipment, which has a vast foreground.
