The most widely used of the stainless and heat resisting steels, Stainless steel 304 offers good corrosion resistance to many chemical corrodents as well as industrial atmospheres. 304 Stainless Steel Pipe has very good formability and can be readily welded by all common methods.

Stainless steel pipe exhibit such characteristics as corrosion resistance, excellent weldability, and good formability.

Surface Finish

A comprehensive collection of finishes is also available from QINGHE STEEL when purchasing stainless steel pipe & tube. Popular finish options include:

  • Also cold-rolled, the 2D finish has a matte surface with low reflectivity.
  • HR / No.1 . This hot-rolled finish has a scaled appearance and so is ideal where the final aesthetic is not an important concern.
  • BA / 2R. Cold rolled and annealed in a controlled atmosphere to retain a highly reflective finish. This highly-reflective finish is achieved by annealing the alloy in a carefully controlled atmosphere.
  • Smooth finish, reflective grey sheen. Most widely used surface finish. The most popular surface finish, 2B offers a smooth appearance with a grey, reflective sheen.

FAQ

Whats the difference between stainless steel pipes and stainless tubes?

The term “pipe” and “tube” are often used to describe the same product, but it is important to know the difference. Though they share the same cylindrical shape, steel pipes are measured by the interior diameter (ID), whereas steel tubes are measured by the outside diameter (OD) and wall thickness. Another difference is that pipes are used to transport fluids and gases, while tubes are used to build parts or structural components.

What types of stainless steel are commonly used for pipes?
304 and 316 grades are most widely used for their corrosion resistance.

What diameter and thickness pipes are available?
Diameters range from 1/8″ to 60″+. Thickness from nominal SCH5S to XXS depending on application requirements.

Why Choose Stainless Steel?

  • Stainless steel extrusions are used for these types of profiles due to the materials’ wear and corrosion resistance. In addition to being essentially rustproof, some grades of stainless steel are also immune to acids and/or other highly corrosive compounds, even in high concentrations.
  • Stainless steel, in general, is a very low maintenance material. It can be repeatedly steam-cleaned or sterilized without degrading and does not require painting or other surface finishes. Stainless steel exhibits high electrical resistance, as well as low thermal conductivity.
  • However, due to its hardness, stainless steel is not easy to extrude. This dictates that wall thickness must be greater than those of extruded shapes made from most other alloys.

What are the common end finishes?
Welded, seamless or mechanical joints are available. Standard end finishes include plain end, beveled, threaded.

What pressures can stainless steel pipes withstand?
It depends on the grade, schedule and joint but normally ranges from 150 PSI – 10,000 PSI working pressure ratings.

How is stainless steel pipe joints welded?
SMAW, GTAW, GMAW processes used with matching filler metals like 309/310/316 for butt-welds andSocket welds.

Does it require any post-weld treatment?
Solution annealing may be specified for corrosive services to maximize corrosion resistance of the weld zone.

What industries utilize stainless steel pipes?
Pharma, biotech, food processing, chemical, hydrocarbon processing plants and marine/desalination widely use it.

Does Stainless Steel rust?

Stainless Steel is very corrosion resistant because it is alloyed with Chromium which reacts to oxygen and creates a rust resistant barrier. This is not to say that stainless will never rust, in certain conditions it may still corrode. For example, 304 stainless is the most common stainless alloy, but in marine environments it will eventually rust. 316 stainless alloy was created with more nickel to be more corrosion resistant in those Marine environments. Other stainless alloys are specialized to be more corrosion resistant in a number of different situations, i.e. 310 alloy is corrosion resistant in high heat environments.

Does surface finish play a role in corrosion resistance?
Polished/shot blasted surface keeps better than ground/as-received by providing less surface area for attack.

How to specify stainless steel pipes in drawings?
Specify material grade, schedule/thickness, diameter, ends, joint type, pressure rating and surface finish.
