Bright Annealed Pipe

Bright annealed stainless steel pipes undergo bright annealing process to achieve a bright effect on the pipe wall.

Roughness: Ra≤0.4μm

BA： Bright Annealing, during the drawing process of steel pipes, there will always be grease lubrication, and the grains will also deform due to processing. In order to avoid the residue of grease in the steel pipe, in addition to cleaning the steel pipe, high temperature annealing can also be used to eliminate deformation. Argon gas can be used as the atmosphere inside the furnace, and the carbon oxygen on the surface of the steel pipe can be combined and burned by argon gas to further clean the surface of the steel pipe and produce a bright surface effect. Therefore, this method of using pure argon gas annealing to heat and rapidly cool to brighten the surface is called brilliant annealing. The effect is related to the content of argon gas and the number of heating cycles
