Surface roughness standard comparison table of sanitary stainless steel pipe
Comparison table of surface roughness mesh number and Ra (um) of sanitary stainless steel pipe as follows:
The reason why sanitary stainless steel pipes are used in food, gas and other fluid pipeline engineering is mainly related to the external roughness (smoothness) of the surface; most sanitary pipe fittings have bright appearance, smooth inner hole, inner and outer surface roughness and finish standard Ra≤ 0.8μm.
