Hot-rolled steel pipe is a steel pipe produced by a hot-rolling process. The production process is to heat a billet to a certain temperature, and then roll the billet into a steel pipe by a rolling machine. Hot rolled steel pipe has the following characteristics:
1. High strength: Due to the hot rolling process, the grain structure inside the steel pipe is denser, so it has higher strength.
2. Corrosion resistance: The surface of the hot-rolled steel pipe is treated with scale, which can effectively prevent the steel pipe from being corroded.
Hot-rolled steel pipes are widely used in petroleum, chemical, natural gas, construction, machinery manufacturing and other fields.
Name
Seamless Steel Tube
Length
MAX 18000
OD
6.0-114.0mm
Delivery Condition
Annealed, Normalized, Normalized and Tempered
Surface treatment
Oil-dip, Varnish, Passivation, Phosphating, Shot Blasting
Application
For high, middle, low pressure boiler and pressure purpose.
Used in heat exchangers and boilers to provide highly energy efficient means of heat transfer. The presence of the internal rifling induces centrifugal forces in the mass flow thereby separating the water from the steam fraction and forcing the water towards the tube wall.
