This arrangement is presented to make it easy for you to determine the availability of tubing or pipe for a particular specification. However, it is often possible to substitute an item in one

class for a similar item in another class when the latter is not

available. For example, pipe and structural tubing may often be

inter-changed, or a hydraulic tube may be used for a mechanical

application. For critical applications, though, especially when

governed by the specifications, care should be taken to insure

that the tube ordered possesses the necessary properties.

Sizes listed herein are those normally available from stock at the time of publication.

However, our stocks are continually being adjusted to reflect changing demands.

The item you need may have been added to stock after this book went to press.

If the particular item you need cannot be supplied from stock immediately, we will

endeavor to obtain it for you, either locally or from another part of the country. With

our special knowledge of tubing sources and numerous contacts in the industry,

we are in a good position to locate the hard-to-get items you need. Use this EMJ

service and your time will be free for other things.

Also, as agents of all leading tubing mills, we can expedite production and delivery

of material direct from the mill. This includes not only special sizes, but also special

analyses and grades such as the following:

MECHANICAL AND STRUCTURAL TUBING

Mechanical tubing is used for a wide variety of mechanical purposes as opposed

to structural and pressure applications. It is generally produced to meet specific

end use requirements which may be static or dynamic in nature.

It is available in a wide range of sizes, shapes, analyses, and mechanical properties. Compared with pipe, it is produced to closer tolerances and better finishes.

KEY TO ABBREVIATIONS AND SYMBOLS

USED ON THE FOLLOWING PAGES

Four-digit numbers (e.g., 1018, 4130) represent analysis designations of carbon and

alloy seamless tubing. All such items are Cold Drawn except when prefixed HF.

Three-digit numbers (e.g., 304, 321) represent analysis designations of stainless

steels. Stainless tubes are seamless except where the designation includes WD,

in which case they are welded and drawn.

Four-digit number followed by temper designations (e.g., 3003-O, 2024-T3) represent alloy and temper of aluminum.
