Preparing The Sheets

Before being selected to roll, the stainless steel sheets go through a number of inspections. Trimming them around the edges is the first step in preparing them.

Rolling Through Rollers

The desired size is then achieved by running the sheets through many rollers. You can see the sheets evolving into tubular shapes in this stage.

Rollers Through The Fitted Welding Machine

The tubular shape must pass through a customised welding equipment in this step. You get precisely rolled tubes by removing the weld beads and scraps from inside these tubular shapes.

Welding Process

The grade and application requirements have an impact on tube welding and forming. For the manufacturing of tiny diameter tubes, we employ TIG welding. Steel sheets are coiled and welded inside of a welding machine. The steel sheets are shaped into a coil before entering the machine. The seam between these coils is then welded to create a tube.

Electric Resistance Welding (ERW) Process

Tube is made using the Electric Resistance Welding (ERW) technique, which involves cold-forming a flat sheet of steel into a cylindrical shape. The steel is then heated by applying current to either of the cylinder's edges, forcing the edges to bond together firmly without the use of welding filler material.

Submerged Arc Welding (SAW) Process

An arc is created between a workpiece and a continuously fed bare wire electrode during the Submerged Arc Welding (SAW) procedure. Additionally, flux is used to create slag, produce protective gases, and provide alloying materials to the weld pool. Gas shielding is not required.

Electric Flash Welding Process

A steel sheet being transformed into a cylinder using the electric flash welding process. The edges are heated until they become semi-molten in this instance, and then they are pressed together until molten steel is squeezed out of the junction and forms a bead.

Annealing

Metal is heated above the point of re-crystallization and cooled to room temperature during the annealing process. The molecular bonds in metal tighten when it is shaped, making it rigid. The metal is put through an annealing process to regain its ductility.

Sinking Process

Tube sinking is a drawing technique that reduces the diameter of tubes. In this drawing technique, a tube is run through a die without the need of a mandrel. Good inner surface quality is not ensured when using a mandrel. The die angel determines the integrity of the outer surface. The die being used produces a uniform surface. A tube can be significantly smaller than it was originally. When cost is a factor, tube sinking is ideal.

Inspection and Testing

Before sending our items to our consumers, we conduct inspection procedures to verify their integrity.
