Frequently Asked Questions — Tube Mill 3 Inch
What tube sizes can the 3-inch tube mill produce?
The mill produces round tubes from 19.05 mm to 76.2 mm OD, square hollow sections up to 60 x 60 mm, and rectangular hollow sections up to 75 x 40 mm with appropriate roll tooling and Turks-head shaping units.
What materials and wall thicknesses can this tube mill process?
It processes Mild Steel (MS), Hot Rolled (HR), Cold Rolled (CR), Galvanized Iron (GI), and Stainless Steel slit strip coils with wall thicknesses from 1.0 mm to 4.0 mm.
Does this tube mill include both internal and external bead scarfing?
Yes. The line features dual carbide bead scarfing stations -- one external scarfer immediately after the squeeze rolls and one internal scarfer inside the tube -- for smooth bore and outer surface finish on every pipe produced.
How does the Turks-head unit produce square and rectangular sections?
The Turks-head consists of four adjustable rolls positioned at 90-degree intervals that reshape the round welded tube into precise square or rectangular hollow sections. Roll sets are changed for different section dimensions.
What is the production speed and daily output capacity?
The line operates at 25 to 50 meters per minute. In an 8-hour shift, this equates to approximately 12 to 20 metric tons of finished pipe output depending on tube diameter, wall thickness, and material grade.
Can the line run continuously across coil changes?
Yes. The line includes a hydraulic strip shear and butt welder for joining successive coil ends, along with an optional strip accumulator to maintain continuous forming and welding during coil changeover.
What warranty and commissioning support does Gagan Engineering provide?
We provide a 1-year comprehensive manufacturer warranty, complete roll tooling and die documentation, foundation drawings, on-site mechanical alignment, welding parameter setup, electrical commissioning, and full operator training across India and export markets.
