GANYEAH manufactures a full range of seam-welded stainless steel tubing from a wide variety of corrosion-resistant alloys in many sizes.

The Annealed & Pickled welded steel pipe production process begins with the rolling of a steel coil to the desired gauge thickness. The outcome is a coil of a flat strip. The next step involves cutting the strip according to the width that corresponds with the size of the tube to be produced.

 

The Annealed & Pickled welded steel pipe is formed by moving the cut coil through a series of rollers, and the seam of the tube is then welded in a chemically neutral environment. A rolling application is used to forge the welded seam, and a heat treating process is used to finish the welded tube. Welded tubes can then be drawn over mandrels and ground if needed to smooth the welded seam and make it nearly impossible to see with the naked eye.

 

Because less drawing and annealing are needed in the manufacture of a welded and drawn tube, the cost of welded and drawn tubing can be less expensive than seamless tubing and can typically be procured quicker than seamless tubing (although stocking of intermediate size starting stock for seamless tubing can reduce this lead time as well).
