Product Introduction

Is 304 stainless steel seamless pipe different from sandblast pipe?

In fact, the difference between stainless steel surface drawing, frosting and sandblasting is the difference in surface treatment process

The drawing surface of 304 stainless steel pipe is a surface texture formed after grinding with a grinding wheel. Granular feeling will be heavier, characterized by increased friction.

Stainless steel tube frosted surface, in fact, is the original color of stainless steel, the surface is not granular, characterized by: with the longer the use of time, there will be more coated, it will be brighter.

Stainless steel pipe sandblasting surface, is made of fiber interference surface texture in an electrochemical way, the particle sense of the surface is between matte and wire drawing, through electrochemical treatment, can prevent oil, that is to say, such a damaged surface is easier to erase oil.

Stainless steel pipes can still be made into color pipes after the treatment of these surfaces, and the types and styles are different.
