Cold rolled seamless steel tube pipe
Cold rolled seamless steel tube is a kind of seamless steel pipe with high dimensional accuracy and good surface finish used in precision mechanical structures, hydraulic equipment or steel sleeves.
-
Hot rolled seamless steel tube pipe
Hot rolled seamless steel pipe is a major category of seamless steel pipes, which are divided according to production methods. Hot rolling is relative to cold rolling. Cold rolling is rolling at room temperature, while hot rolling is rolling above the recrystallization temperature. Seamless steel pipes are relative to welded steel pipes. Seamless steel pipes are usually made by perforating round steel, while welded steel pipes are usually made of steel plates welded in different ways.
