Each U bend tube of our range is rigorously quality checked by our team of talented professionals on every stage of production to deliver the clients defect free best quality products. These U bend tubes can be custom designed in various diameters as per the requirements of our clients.
- Boilers, heat exchangers, super heaters, condensers
- Production Standard, Grade, Steel No:
- ASTM A688/A688M-Welded Austentic Steel Feedwater Heater Tubes.
- ASTM A 312/213/269,DIN 17458/2462,BS3605/1,JIS, ASME SA556G3429/3459,ISO1129/2037/9329,GB/T14975/14976/13296 and so on.
- TP304,TP304L,TP316,TP316L,TP321,TP310S,TP347H,TP316Ti, Carbon steel, alloys and so on.
- The removal of beads is done as per standard specifications.
- Bead is cold worked.
- It is brought in level with the base metal.
- Before heat treatment on tube mill, bead rolling is made in-line.
- This will help in recrystallization of weld structure.
- The weld structure will also homogenize faster in annealing process.
- Length: unbending length or fix length
- Mill test certificate: according to EN 10204 3.2
- Packing: Wooden cases, bundle or plastic bags, plywood boxes
- Oil-dip, Varnish, Passivation, Phosphating, Shot Blasting.
