6 Important Types of Stainless Steel Pipes and Tubes

Stainless Steel, abbreviated as SS, is one of those iron alloys, which never loses its relevance across various industries. Why? The answer is advantages that it offer. This material offers excellent resistance against oxidation, and requires low maintenance. This advantage makes it popular among various industrial systems. Today, SS is offered in various grades. Pipes or tubes made from diverse SS grades are very popular in the market. Which tube is suitable for your industry? In this post, we will discuss 6 popular categories of stainless steel pipes/tubing. The information provided will help you understand, if any of these SS pipes and tubes are suited for your use.

6 Popular Stainless Steel Pipes and Tubes Discussed

If you are looking for stainless steel pipes and tubes for your industrial applications, you may come across the following types.

  1. Standard Stainless Steel Pipes: This term is applicable to all SS pipes. At times, it may become difficult to select a particular grade. However, the selection should be made on the basis of function, and its performance in various environments. For applications in regular environments, pipes and tubes made from grade 304 are preferred. This grade offers excellent resistance to corrosion and chemicals. Type 304 is not ideal for high temperatures 800 to 1650°F because they are prone to carbide precipitation. However, stainless steel type 304L is considered ideal for such applications because they have low amount of carbon. Also, SS tubes made from 304L are used when high temperatures or welding is involved.
  2. Anti-corrosive Stainless Steel Pipes: This category is ideal for applications that require excellent corrosion resistance. Martensitic and ferritic varieties are always manufactured to be annealed or heat treated. Austenitic varieties of stainless steel pipes feature high nickel and chromium contents. Austenitic stainless steel tubes can also be used under the same conditions as martensitic and ferrite varieties.
  3. Hydraulic Line Tubing: These tubing are used for hydraulic systems, and fuel lines. Hydraulic tubing have smaller diameters. These tubes are made from 304L or 304 stainless steel variants. These tubing have durable construction, and can resist corrosion easily.
  4. Pressure Pipes: You can easily find large diameter, welded, and high pressure pipes for high temperature environments. These pipes are made from austenitic and ferritic variety of steel.
  5. Mechanical Tubing: Stainless steel mechanical tubing is used in bearings, cylinders, and other hollow parts. These tubing can be created in a variety of shapes such as rectangular, square, etc. Generally, A554 and ASTMA 511 grades are used for creating mechanical tubes.
  • Aircraft Tubing: In aircraft applications, nickel and chromium made tubes are used, due to their high corrosion, and temperature resistance properties. However, the applications that require high strength, stainless steel tubes are used. Low-carbon types of tubes are a choice for welding SS tubes. For applications that require welded and seamless tubing, aircraft structural material is used. This material is made according to Aerospace Material Specifications (AMS) or Military Specifications (MIL Specs).
  1. Sanitary Tubing: As the name suggests, these pipes are used in food and beverage processing industries, where sanitation takes a priority. Generally, stainless steel sanitary pipes are made from ASTMA270. These tubes offer high corrosion –resistance and are easy to maintain.
