Description

Seamless Polished Stainless Steel Pipe With SS304 SS316 SS304L SS316L

Smls polished pipe is a hollow part with no seams around the strip, after polished outside or both inner side and outside, the smls polished pipes are widelyused in saniatry, food, drinking water, medicine field.

With polishing, process, the oxide layer on the surface of smls pipes/ tubes is damaged, it is better to passivate the surface with acid solution, otherwise stainless steel pipe is easy to rust.

Polished Surface Functions as below:

  • Enables sealing of high pressure gases and liquids
  • Cosmetic purposes
  • Enables the use of optical flatness measurement instruments
  • Reduces the amount of surface and sub-surface damage
  • Provides better uniformity of surfaces requiring epitaxial processes or deposited materials
  • Generates sharper edges on cutting tools

Material Grades:

Stainless steel is the abbreviation for stainless and acid resistant steel. Steel that is resistant to weak corrosive media such as air, steam, water, or has rust resistance is called stainless steel; And the steel grade that is resistant to chemical corrosion media (such as acid, alkali, salt, etc.) corrosion is called acid resistant steel.

The most common used material is SS304/304L, SS316/316L, DUPLEX SAF2507, SAF2205, Detail’s specification of the material as below.

FAQ/ Customer Question and Answers

Q: What is difference between tubes and pipes?

A: Tubes and pipes are difficult to identify occasionally and some people use the name of tube and pipe interchangeably. However, there are significant differences between tubes and pipes. Tubes are measured in outer diameter and wall thickness. The tube is produced with close tolerance range and requires precise outer diameter and wall thickness to identify its working pressure.

Q: What is Difference Between Stainless Steel Pipes Seamless and Welded?

A: 1) Strength: The main difference between seamless and welded pipes is in their strength. Seamless pipes are stronger because they do not have any welded seams. Welded pipes are weaker because the welds can act as weak points that could break under high pressure.

2)Cost: Seamless stainless-steel pipes are more expensive than welded ones because they require more time and effort. Welded pipes are less expensive because they can be made quickly and with less precision.

3) Applications: Seamless stainless-steel pipes are typically used in high-pressure applications, such as hydraulic systems, while welded pipes are used in low-pressure applications, such as water piping.
