Welded and drawn is the preferred tubing choice in terms of economy, lead time and tolerancing compared to seamless in most instances.

SUS304 Stainless Steel Grade Welded And Drawn Tubing from GANYEAH begins with the same high quality welded straight lengths and coiled tubing that has been chosen for countless installations throughout the world.

The tubing is bathed in lubricant before it is drawn through a die.

Tubing may be drawn several times in order to meet strict customer specifications for size, strength and finish.

The drawing process provides the following advantages: Heavier wall to outer diameter (OD) ratios, Additional strength, Exceptional dimensional control, Superior surface finish Enhanced bending, flaring, and formability of tubing, Greater control over ovality

Each drawing operation is followed by an annealing operation. The additional cold work and annealing result in "seamless" quality.

Tube vs. Pipe?

Manufactured to a set outside diameter, tube is expressed as 1.5" OD, .065" wall. Pipe is specified by a nominal, not actual, inside diameter. The wall thickness of pipe is described by the "schedule" such as schedule 40.
