FAQ

 

 

Q1: Anto so pandumaan na tubo na API 5L X60 PSL1 tan PSL2?

A1:Say PSL2 et mangiiter na mas malet ya chemistry control, mas malet ya testing (maslak et walay epekto to), mas istrikton NDT/acceptance, tan mas mabiskeg ya traceability nen say PSL1.

Q2: Panon kon pilien so ERW (HFW) LSAW vs SAW parad tubo na 58 X60 ya tubo na tubo?

A2:Pilien so kapal na OD/pader, say nakaukolan a sakop na NDT, tan proyekton NDT{0} parad melag-ed-tame a kabaleg, LSA/SSAW parad mas baleg iran diamet tan mas ambelat iran bakor.

Q3: Antoy nepeg kon kerewen parad X60 welded line pipe ed sour service?

A3:Mankerew na PSL2 plus hardness limits, HIC/SSC testing (no nibaga), tan kompleton MTC/traceability + NDT + hydrotest package.
