An Engineer’s Guide For Selecting The Right Steel Tubing

The engineer has a lot of options when it comes to selecting the ideal steel tubings for any application. Stainless steel tubes in grades 304 and 316 are the most commonly utilized. However, ASTM also provides engineers with the best solution for their applications. Being in the specification guidelines, it meets budgetary goals while yet providing required performance over the product’s lifetime.

Whether to choose a seamless Vs Weldings


While selecting the tube material you should know whether it should be made for Seamless or Weldings Tubes. Stainless steel 304 seamless tubes are made from reputed high-quality material. The process of making seamless Tubes are made from giving Extrusion, a high-temperature shearing technique; or rotational piercing, an internal tearing procedure. Seamless Tubes are often offered for high walls so that they can be stood up with High Pressures Environments.

A welded tube is formed by rolling a length of steel strip into a cylinder, then heating and forging the edges together to form a tube. It is also often less expensive and has shorter lead times.


Prices vary greatly depending on the quantity purchased, availability, and OD-to-wall ratio. The supply and demand of foreign materials have pushed prices all over the place. Nickel, copper, and molybdenum prices have all risen and fallen dramatically in recent years, having a considerable impact on steel tube prices. As a result, extra caution should be exercised when putting together long-term budgets for alloys with higher alloy levels, such as TP 304, TP 316, cupro-nickels, and alloys containing 6% molybdenum. Low-nickel alloys such as Admiralty brass, TP 439, and the super ferritic are more stable and predictable.
