We offer polished stainless steel tubing and pipe with a wide range sizes in welded type, stainless steel grades include 201, 304/304L, 316/316L and other stainless steels, tubing forms have round tubing, square tubing, rectangular tubing.
Polished finishing is a value adding service, polishing will make welding seam integrity with base metal after heat treatment, and have a visible bright surface, furthermore, it can make a uniform and smooth surface, and easy to clean, no dark scale on tubing surface, polished tubing have a low Ra value in roughness.
We can offer both Mechanical Polished and Electropolished service, for amount of tubing, we usually use mechanical polished method, grinding the dry surface with an abrasive belt.
There are several polishing equipment to use, either outside surface ir inside surface, we have capacity to offer sanitary and food grade standard for special applications.
Stainless Steel Polished Grits
- 120 grit
- 180 grit
- 320 grit
- 400 grit
- 600 grit
Ra refers to roughness average, which is the measure of roughness of a surface and measured in micrometers (μm), Ra value is to describe Average scratch depth of tubing surface, the more smooth surface the Ra value smaller, we provide minimium Ra value is 0.05 μm.
Polished Tubing Applications
Stainless steel polished tube is wide used in food processing, bear, beverage, drinking water, it is also used for construction purpose, like handrail required a bright surface, polishing inside surface for stainless steel sanity tubing conforming to ASTM A270 specification.
