1.Seamless (SMLS)

• Rot bilong mekim: Billet hiting → Piercing → Rolling → Sizing → Solution Annealing → Pickling → Testing.
• Gutpela: Nogat 'weld seam', gutpela long hai-presa na bikpela sevis.

2.Welded (ERW/EFW)

• Rot bilong mekim: Strip o plet fomim → Longitudinal/spiral welding → Solution annealing → Sizing → Straightening.
• Rot bilong Weldim: ERW/HFI, TIG/GTAW, SAW, EFW i dipen long OD/WT.
• Gutpela samting: Kost-i gutpela, bikpela sais i stap, ol rot bilong klinim ples wantaim rausim ol 'bead'.

3.Heavily Cold Worked (HCW)

• Rot bilong mekim: Daunim kol long weldim paip + 'annealing'.
• Gutpela samting: Strong i go antap, ol samting i no strong tumas, na pinis bilong en i gutpela moa.

4.Hit Tritmen na Pes

• Solusen Annealing: 1050-1150 digri hariap 'quench'.
• Ol opsen bilong pes: Annealed & pickled, bright annealed, satin-polished, mirror-polished.

5.Kwaliti Kontrol

• Hydrostatic testing, Eddy Current/UT, Radiography long seam & bodi.
• Mekanikel tes: Tensile, yield, hardness, flattening/flaring.
• Ol tes bilong korosen: ASTM A262 (IGC), ASTM G48 (pitting).
