We are a leading manufacturer of stainless steel and high nickel alloy tubing.
The Associated Tube Group, a Division of Samuel, Son & Co., Limited, has manufacturing facilities in Canada and Mexico. Our sixty-plus years of experience in manufacturing welded and cold-drawn stainless tubing is reinforced by a commitment to strong product development, manufacturing and metallurgical support. Our capabilities include laser, TIG and plasma welding technologies, precision cold drawing, custom cutting and end finishing, polishing, fabrication and custom packaging.
Corrosion and Heat Resistant Tube and Pipe
Samuel Associated Tube Group (Samuel ATG) manufactures welded and welded cold drawn tube and pipe in over fifty (50) grades of stainless steel. Our products are suited for use in corrosive environments where high pressure and high temperatures challenge material integrity.
Product is available in T.I.G., plasma, laser-welded, or cold drawn configurations, bright annealed, or annealed and pickled. Product is available in sizes 3/16˝ (4.7 mm) to 6 5/8˝ (168.1 mm) and also in many D.I.N. and J.I.S. sizes.
Samuel ATG offers quality control testing that includes eddy current, laser measurement, pneumatic and hydro-static as well as a full array of destructive and corrosion testing.
Small Diameter Tube
Accredited to ISO/ TS 16949:2009 and PED 97/23/EC Ann1, Sec. 4.3, Samuel ATG has over sixty years of experience in the manufacture of small diameter sizes, 3/16˝ (4.7 mm) to 3/4˝ (19 mm) O.D. in many stainless steel alloys. Small diameter products are supplied to automotive, industrial and residential heating, HVAC, power generation, oil & gas recovery, medical, and food & beverage markets.
Samuel ATG provides a bright annealed, O.D. conditioned product that is continuously laser micrometer and eddy-current tested in-line. The product has a precise O.D. and consistent mechanical properties, making it highly desirable for fabrication or applications where no O.D. leak paths can be tolerated.
Shapes and profiles represent unique challenges in dimensional tolerances, mechanical properties, tooling, testing, and manufacturing processes. With our extensive expertise in non-round shapes and profiles, we leverage our cold drawing capabilities to ensure optimal turnaround of prototypes for our customers, expediting time to market and minimizing tooling costs.
In addition, we can provide a full range of value-added options such as cutting, end-finishing, bright annealing, weld cold-working, in-line non-destructive testing, inspection, and cleaning. Custom cutting and packaging are also available to suit customer requirements.
Cold Drawn Tube
Cold-drawn tubes provide reliability for automotive, fluid power, power generation, oil & gas recovery, electronic products, food & beverage, and recreational applications. Samuel ATG has the capability to manufacture cold-drawn tube to precise tolerances and high quality surface finishes in light and heavy wall configurations. Of note, Samuel ATG can produce cold-drawn round tube or shapes and profiles.
Options such as bright annealing, special tempers, polishing, cutting, end finishing, and cleaning are available. Product can be produced by reduction over a plug, mandrel or through a die, with I.D. surface finishes of 30 rms or better and tolerances of +/- .0015˝ (0.38 mm).
Our stainless steel tubes can be cold-drawn over other materials such as carbon steel, for strength, cost reduction or other engineering considerations.
