Stainless Steel Pipes of Different Types

Stainless steel is a multi-faceted material that is made up of a stainless steel alloy, and a tiny amount of chromium. The addition of chrome enhances the resistance to corrosion of the material which is what earned the name stainless steel. It is often utilized in a wide range of different applications, including the manufacturing of tubing and pipes. Based on the intended use of the pipe that is made of stainless steel, it can be divided into various types. Stainless Steel Piping.

Tubes and pipes are often difficult to classify and are often classified according to their purpose. Apart from these classifications, stainless steel can also be differentiated by type. For pipe and tubing applications Type stainless steel 304 is the most popular choice because it is extremely chemical and also corrosion-resistant. Other stainless steel types are often enriched with additives (such as molybdenum or nickel) which enhance the characteristics that are beneficial in certain applications.

Stainless Tubing of Steel to resist general corrosion


This broad category of steel is ideal for those applications that require resistance over other characteristics. The ferritic and martensitic varieties of steel (those are made of the highest concentration of chrome) are designed to be heat-treated or annealed. Austenitic Stainless steels (those that have high chromium and nickel content) have a higher resistance and can be utilized under the same general conditions as martensitic and ferritic types.

Stainless Steel Pressure Pipe

These kinds of pipes made of stainless steel are constructed out of solid chromium, or a chromium-nickel combination. Different types that are made of pressure pipes consist of seamless or welded pipes and electric fusion-welded pipes for high-pressure applications, huge diameter welded pipe suitable for high-temperature or corrosive applications, and ferritic seamless or austenitic stainless Steel Sanitary Tubing

For situations where stainless-steel tubing or piping has to be in contact with food or other products that are sensitive hygiene is a major priority. Stainless steel sanitary tubing is used in such applications because it has high corrosion resistance, doesn’t tarnish, and is easy to keep clean. For certain applications, various tolerances are possible. The standard grade used in these kinds of applications is ASTMA270.

Stainless Steel Mechanical Tubing

For applications like bearings, cylinders and other hollow-formed components that require stainless steel tubing are often utilized. Tubing is manipulated to create different cross-sectional forms like rectangular and square, as well as the more traditional round tubing cross-section. Applications that require high-strength stainless steel tubing for aircraft can be welded or work-hardened but work-hardened components are not recommended for use with certain types of corrosive materials. Low carbon stainless steels are the most popular option for welded components.

In applications that need seamless or welded tubing that is larger in dimensions (1.6 to 125 millimeters in diameter outside), Aerospace tubing for structural use is employed. This kind is made of stainless steel made by Aerospace Material Specifications (AMS) or Military Specifications (MIL Specs).


Aircraft Hydraulic-Line Tubingis another kind of tubing for aircraft, is utilized in aerospace applications for fuel-injection lines as well as hydraulic systems. It tends to be compact. It is typically made from kinds 304 or 304L stainless

Stainless Steel in Water Distribution

There are miles of pipelines in the world that are used for the transportation of water for drinking. Pipelines must provide resistance to corrosion of the water and soil chemistries as well as the treatment chemicals to ensure an extended service life as well as a hygienic supply of drinking water. Type 316 (2-3% Mo) stainless steel has been found to offer the required corrosion resistance in a majority of applications at a price that is comparable to other piping materials. If additional protection against corrosion may be required, such as shoreline installations, duplex SS (3.0-3.5% Mo) is a good choice to meet the requirements for sanitation, cost, and longevity.

stainless steel pipes are used for their uses and applications

To answer “Why the stainless steel?” these and other positive properties of stainless steels containing Mo are listed in the following manner:

  • Excellent resistance to corrosion Excellent corrosion resistance SS is much less prone to being oxidized caused by biocides and water than carbon steel as well as cast or ductile steel. This means they have longer pipelines.
  • Protection against corrosion internal and external coating isn’t necessary for SS as are cathodic safeguards required. This lowers the cost of the system as well as makes stainless steel suited to the environment.
  • Materials that are hygienic because of their extremely good static film stability, SS are inert within the water. It is safe to leach alloying components (Cr as well as Ni) is not dangerous. In turn, they improve the drinking water of a higher quality.
  • The coefficient of friction Lower friction when compared to carbon steel that is cement-lined pipes or corrosion-resistant carbon steel, which results in less loss of pressure in the pipeline. This allows you to decrease the size of the pipes, and lower the cost of capital. This also accounts for less adhesion to deposits and lowers the colonization of bacteria. They also are tolerant of high flow rates.
  • Excellent toughness as well as toughness – SS and duplex types, have superior mechanical properties compared to the carbon-steel and cast iron pipe. This means that there is a reduction in wall thickness (with the removal of any to allow for the corrosion) and leads to savings in investment costs. A higher degree of ductility can be beneficial in terms of security e.g. if there is an earthquake.
  • Erosion-corrosion Duplex stainless steels are more resistant to corrosion than carbon steels, particularly in the case of sand particles.
  • Fabrication is easy The SS can be fabricated with ease of forming or machining, as well as welding, along with their ductility allows for simple installation and modification.
  • Maintenance ease With the highest corrosion resistance and simple welding water leaks are dramatically reduced, possibly from 25% as low as 5%, which results in further cost savings. This is becoming more crucial because of the rise in the cost of water as well as water treatment.
  • Outstanding durability As SS are impervious to corrosion in crevices, cavitation, and wear in clean and polluted water as well as being in the air (even polluted) and are affordable for long-term use and don’t contribute to environmental pollution.
  • Recyclable The HTML0 SS is completely recyclable and some of their initial cost could be recovered if they are reused.
