Stainless steel is a versatile material comprised of a steel alloy and a small percentage of chromium — the addition of chromium adds to the material’s corrosion resistance, a trait that earned stainless steel its name. Because stainless steel is also low-maintenance, oxidation resistant, and doesn’t affect other metals it comes in contact with, it is frequently used in a large array of applications, especially in piping and tubing manufacturing. Based on the end use of the pipe, stainless steel piping is broken down into several categories.
Stainless Steel Pressure Pipe
This type of stainless steel pipe is made from either solid chromium or a chromium and nickel combination. Types of stainless steel pressure pipe include seamless and welded pipe, electric fusion welded pipe for high-pressure applications, large diameter welded pipe for corrosive or high-temperature applications, and seamless and welded ferritic and austenitic stainless steel pipe. And there is also stainless steel AP tubes.
Stainless Steel Sanitary Tubing
For applications where stainless steel tubing or piping must come into contact with food and other sensitive products, sanitation is a high 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 specific applications, different tolerances can be achieved. The grade typically used for these applications is ASTMA270.
Stainless Steel Aircraft Tubing
In highly-specific aircraft applications, chromium and nickel type stainless steel bright anneal tubes is used because of their heat and corrosion-resistance. Found in applications that require high-strength, stainless steel aircraft tubing can be work-hardened or welded, although work-hardened pieces shouldn’t be used with some kinds of corrosive substances. Low-carbon types of stainless steel are a common choice for welded parts.
For applications that require seamless and welded tubing in larger sizes (1.6 to 125 mm in outside diameter), aircraft structural tubing is used—this type of stainless steel tube is manufactured according to Aerospace Material Specifications (AMS) or Military Specifications (MIL Specs).
Aircraft Hydraulic-Line Tubing
Another type of aircraft tubing, aircraft hydraulic-line tubing is used in aerospace applications as fuel-injection lines and hydraulic systems, and tends to be small. It is often manufactured from types 304 or 304 L duplex stainless steel tube because of the steel’s high-strength, corrosion-resistance, and ductility.
Stainless Steel Pressure Pipe
This type of stainless steel pipe is made from either solid chromium or a chromium and nickel combination. Types of stainless steel pressure pipe include seamless and welded pipe, electric fusion welded pipe for high-pressure applications, large diameter welded pipe for corrosive or high-temperature applications, and seamless and welded ferritic and austenitic stainless steel pipe.
