Q1: Anto so pandumaan na tubo na API 5L X65 PSL1 tan PSL2?

A1:Say PSL2 et mankaukolan na mas malet ya chemistry control tan mas malet ya testing/traceability, kanian kaslakan ya uusaren itan parad saray kritikal ya pipeline.

Q2: Panon ak ya manpili na ERWW vs vs SSAW parad API 5L X65 ya in-weld na tubo na linya?

A2:Pilien so nakaukolan a kapal na OD/pinaryo tan say spec na proyekto{}} parad saray mas melag/a-peg ya sukat, LSA/PAW parad mas baleg iran balyena tan mas makapal iran padir.

Q3: Anto ran dokumento tan test so nepeg kon kerewen parad API 5L X65 welded line pipe antis ya saliwen?

A3:Kerew na 3.1 MTC ya walay pan-inuman na petang, say lebel na PSL, lebel na PSL, resulta na CSL, resulta na NT unong ed pankaukolan), hydrodo, tan antokaman ya ampetang no onaplika.
