Q1: Ke phapang efe pakeng tsa API 5L X65 PSL1 le PSL2 welded line pipe?

A1:PSL2 e hloka taolo e matla ea k'hemistri le tlhahlobo e thata haholoanyane / ho lateloa, kahoo hangata e hlalosoa bakeng sa lipeipi tsa bohlokoa.

Q2: Ke khetha joang ERW vs LSAW vs SSAW bakeng sa API 5L X65 weld line pipe?

A2:Khetha ho ipapisitsoe le botenya bo hlokehang ba OD/ lebota le lintlha tsa projeke-ERW bakeng sa boholo bo nyane/bohareng, LSAW/SSAW bakeng sa lidiameter tse kholoanyane le mabota a makima.

Q3: Ke litokomane life le liteko tseo ke lokelang ho li kopa bakeng sa API 5L X65 weld line pipe pele ke reka?

A3:Kopa 3.1 MTC e nang le traceability nomoro ea mocheso, boemo ba PSL, CE/CEpcm, liphetho tsa NDT (UT/RT kamoo ho hlokehang), hydrotest, le litlhoko life kapa life tse bolila-ha ho hlokahala.
