Industry Information

Stainless steel tubing, or SS tubing, is a hollow, cylindrical metal form used as equipment components or as the medium through which fluids or gas pass. Manufacturers employ welding or seamless tubing procedures to produce stainless steel pipes and tubing. SS tubes are used in the medical, dental, automotive, petrochemical and semiconductor industries, among others.

Stainless steel tubing is used in applications ranging from and dental implants medical instruments, such as hypodermic tubing like syringes and hypodermic needles, to hydraulic systems, fuel lines and engine conduits. The paper and pulp industry has become increasingly reliant on stainless steel pipes and stainless steel tubes because of the corrosive and aggressive fluids used in the process of paper making. Manufacturers produce different variations of stainless tubing and piping, including stainless steel pipe fittings, which are pipe attachments, corrugated stainless steel tubing which is flexible and made with a PVC outer layer, stainless steel square tubing, which is an alternative to the usual round shape, and seamless stainless steel pipe, which, because of their manufacturing process, are more pressure resistant compared to welded pipes.


Stainless steel tubing and piping is produced via welding, which involves roll forming stainless steel and connecting the formed portions along a seam through fusion, leaving the middle hollow. Welding achieves a higher degree of precision without secondary operations. The degree of precision required of the stainless steel tubing manufacturers depends on the industrial application. It can also be produced through metal spinning, which is a cold worked metal fabrication technique comparable to a potter forming clay, except a metal spinner uses a flat round disc of sheet metal which is rotating on a spinning lathe. However, the metal spinning process is limited to the production of concentric shapes, including tubes and pipes. Perhaps the most easily available type is the seamless stainless steel pipe or tube, which is formed by extrusion. A solid billet is drawn over a piercing rod, which creates a hollow shell without any seams, unlike welding, where seams are unavoidable. Seamless tubing and piping is the most reliable when it comes to retaining high amounts of pressure, as it is much less likely to split. For this reason, hypodermic tubing is made this way.

Although similar, stainless steel pipes and tubes differ in slight manners of properties and applications. All piping is considered tubing and is mostly distinguished by its uses, which are mainly for the transmission of water or gas and used almost exclusively in the plumbing and pipe fitting industries. Different pipe fittings are also often made out of stainless steel. These attachments do a number of different useful things for plumbing and piping. Many connect tubes together, including nipples, which are threaded on both sides, elbows, which turn tubes at a 90 or 45 degree angle, reducers, which allow differently sized pipes to join, and tees, which are able to join 3 different pipes. Caps and plugs cover pipes and keep their contents contained.  Tubes, on the other hand, are more diverse in their implementations. They are usually round, but square types are manufactured to make stepladders, display racks and bar foot railings. Corrugated tubing, used in gas heating systems, is made of 2 layers-the exterior is a PVC covering and the interior is stainless steel tubing. Corrugated tubing is easily bent, and therefore needs fewer connections.

A number of stainless steel alloyed tubes such as 304 stainless steel tubing and 316 stainless steel tubing are used because of its excellent corrosion resistance, ease of cleaning, low maintenance and long run cost-effectiveness. Even though stainless steel may require a higher initial cost than other metals, maintenance and replacement costs are lower. Stainless steel tubing is less expensive than titanium, a metal with similar properties and applications. Stainless steel tubing is used very often within the medical industry. This type is referred to as hypodermic tubing, and is the medium for transferring medicine from a bottle to under the skin and into the bloodstream. Stainless steel is used because its smooth and crack-free surface is very easy to sterilize. Hypodermic needles and syringes are very small and considered an example of small diameter tubing. Because these tubes are so tiny, they have their own set of gauge sizes, which are determined by the outside and inside diameter of the tube, instead of wall thickness and outside diameter. Hypodermic tubing can range from .005" to .259" outside diameter and .002" to .239" inside diameter.

Stainless Steel Tubing Types

  • 304 stainless steel tubing is a hollow, cylindrical machine and piping component made of grade 304 stainless steel alloy and used most commonly to transport fluids and gases.
  • 316 stainless steel tubing is a hollow, cylindrical machine and piping component made of grade 316 stainless steel alloy and used most commonly to transport fluids and gases.
  • Corrugated stainless steel tubing is a multilayered hollow cylindrical object used as an alternative to traditional steel piping as the medium through which gases are transported.
  • Hypodermic needles are medical instruments that use stainless steel tubing to move fluids.
  • Hypodermic tubing is a slender, hollow, cylindrical length of stainless steel, a puncturing point made at one end to form a needle which is commonly used as the medium for introducing medicine or drugs under skin.
  • Medical tubing is often made from stainless steel because of its hygienic nature. Medical tubing is also used in the production of instruments and implants for the medical industry.
  • Nickel tubing is a common type of tubing. Nickel is often used in combination with copper in many applications, including those in the marine industry that involve moderate exposure to chlorine, to which nickel-copper alloys is resistant.
  • Small diameter tubing is used in equipment found in medical and dental applications, including those used in minimally invasive procedures. Capillary tubing, for example, measures less than or equal to 0.188 inches in outside diameter.
  • SS tubes are hollow cylindrical objects, similar to pipes, used as the medium through which fluids and gases are transported as well as various other equipment components, such as hydraulic cylinders.
  • Stainless steel bars of different shapes are utilized in the construction and transportation industries because of the bars’ high strength and low maintenance requirements. Stainless bars and rods provide excellent structural support and reinforcement.
  • Stainless steel pipes are used in applications involving corrosive fluids, high temperatures and high contaminant levels because of the great corrosion resistance of stainless steel pipes. Industries in which stainless steel pipes are popular include the oil/gas, pulp and paper and water/wastewater industries.
  • Stainless steel pipe fittings are attachments used to connect or close the end of pipes and tubing to increase in-line, offset, multiport and mounting capabilities.
  • Stainless steel square tubing is a pipe like hollow piece of hardware having four sides of equal length which is used in applications in which traditional round or oval stainless tubes are not acceptable.
  • Stainless steel tubes are hollow cylinders made of stainless steel that are often used for the transportation of liquids and gases.
  • Stainless tubing refers to the hollow cylinders in equipment through which fluid passes.
  • Syringes are small, hollow tubes used for injecting or withdrawing fluids for medical purposes.
  • Thin wall tubing consists of extremely thin stainless tubing, the walls of which usually measure 0.12 inches or thinner. Despite its thinness, thin wall tubing still provides insulation and strength and is commonly used in medical and aerospace applications.



Stainless Steel Tubing Terms

Annealing – Reducing hardness and stress in a metal, such as stainless steel, through heating and cooling applications.  
 
Bright Annealing – A form of annealing in which the level of atmospheric gas is reduced in order to remove surface oxides from the surface of the stainless steel and to prevent discoloration during the annealing process. This process is responsible for the bright, shiny appearance associated with stainless steel.
 
Burst Pressure – The internal pressure limit of stainless steel tubing at which point the tube material will expand to the point of deformation or bursting.
 
Cold Drawing – A cold forming process, commonly used in tube and pipe diameter reduction, in which a tube is drawn through a carbide die. The diameter of the emerging stainless steel tube or stainless steel pipe reflects the size of the die.
 
Concentricity – A characteristic of a welded stainless steel tubing in which wall thickness remains consistent throughout the stainless steel tubing, and the inside and outside diameter centers are equivalent to one another.
 
Corrosion – The decay of metals by chemical agents, which convert them to nonmetallic products. Stainless steel has a passive film created by the presence of chromium and often other alloying elements, such as nickel and molybdenum, that resists this process.
 
Degree of Bend – The depth of bend or the sweep of the arc. The minimum degree of bend is about five degrees, while the maximum degree of bend in rotary-draw bending is 180 degrees.
 
Destructive Testing – The testing of stainless steel tubing properties, such as tensile strength, yield strength, hardness, burst pressure and bending.
 
Eccentricity – A characteristic of seamless tubing in which wall thickness is not consistent throughout the tube.
 
Hardness – A characteristic of tubular products that is measured on samples of tubing using a standard Rockwell Penetrator and recording the results on the Rockwell "B" scale. Hardness is the direct result of annealing temperatures and material properties; in general, as the hardness number increases, both tensile and yield strengths increase along with a corresponding decrease in elongation (ductility).
 
Hydrostatic Testing – A test in which water is introduced into the stainless steel tubing at high pressure levels in order to test for holes and porous parts. Because hydrostatic testing is a nondestructive test, the water pressure level does not surpass the stainless steel tubing yield strength.
 
I.D. (Inside Diameter)
– A term that refers to the diameter of the interior portion of stainless steel tubing and pipes. The measurement of the stainless steel tube or stainless steel pipe is not included in I.D.

IPS – A pipe specification system that associates certain nominal pipe diameters with standardized wall thickness called “schedules.” The same schedule number will have a different fixed decimal inch value for each nominal diameter.

O.D. (Outside Diameter) – A term that refers to the diameter of the exterior portion of stainless steel tubing and pipes. The tube or pipe is included in the O.D. measurement.
 
Ovality – A quantitative measurement of how "round" a tube is, which is derived by comparing width to height. Limits of ovality are specified on the appropriate ASTM specification of a product.
 
Passivation – The creation of a passive oxide layer on stainless steel, which is responsible for the high corrosion resistance of stainless steel used in stainless steel tubing.
 
Residuals – The impurities remaining in mini-mill stainless steels, which result from the wide variety of metals entering the process.   
 
Seamless Tubing
– The creation of stainless steel tubing through the use of a piercing mill. During the process, a round blank is pierced to produces the stainless steel tubing, which produces inconsistency in wall thickness throughout the tube that can be fixed through secondary operations.
 
Welded Tubing – The creation of stainless tubes through roll forming and fusing the stainless steel along a seam. Welding provides consistency throughout the stainless steel tubing.
