Trends in hydraulic tube production during times of shortages, Part II
U.S. manufacturers have long relied heavily on foreign suppliers for hydraulic pressure line tubing products, in many cases using legacy products and legacy end-forms to make leak-proof seals. Bringing production to the U.S. is a matter of using two niche manufacturing specifications to make the tube and adopting alternative end-forms.
Trends in hydraulic tube production during times of shortages, Part I
U.S. manufacturers have long relied heavily on foreign suppliers for hydraulic pressure line tubing products, and the market is ripe for change. This change can come in the form of two SAE specifications, J356 and J356A, for large- and small-diameter hydraulic products, respectively.
Understanding steel tube and pipe metallurgy
Many involved in tube and pipe use the material’s hardness as a proxy or shorthand for the material’s other mechanical properties. While hardness correlates well to the material’s tensile strength, it doesn’t tell the whole story.
Fabricating long coils rather than short straights
Most fabricators work with standard lengths of straight tube, but this isn’t the only possibility. Many alloys are available in coiled form, which can lead to faster processing, better use of floor space, and increased material yields.
Minimizing wall thickness variation in seamless tubing
All mechanical steel tubing has some amount of wall thickness variation. Wall variation in welded tubing results from the strip manufacturing and tube welding processes. Seamless tube, which is created from a hot billet of solid steel, has wall variation that results from tooling wear, bearing and shaft variation, and normal hot-process variation. The wall thickness in seamless tubing varies in the cross section and along the tube's length.
