API 5L X70 umurongo udafite ibyuma

Umuyoboro wa API 5L X70 ni ibikoresho byo mu rwego rwo hejuru mu bikoresho bya API 5L. Yitwa kandi umuyoboro wa L485, kuko ari imbaraga zitanga umusaruro
byibuze muri 485 Mpa (70,300 psi). API 5L X70 ikubiyemo ubwoko bwinganda muburyo butandukanye kandi busudira (ERW, SAW), byombi bikoreshwa
yohereza peteroli na gaze.

API X70 umuyoboro wibyuma bya karubone urashobora gusobanurwa nkumuyoboro wibyuma birimo karubone nyinshi hamwe nuruvange. API 5L X. Kwiyongera kwibi bintu byose bifasha kunoza imiterere ya mashini ya X70 ya karubone.

Ibi birashobora kugaragara uhereye kumbaraga nke (485 MPa) ya API 5L X70 Icyiciro B LSAW. Ifite kandi imbaraga zingana na 635 MPa. Ubuso bwa API 5L X70 SCH 40 Imiyoboro ya DSAW ivurwa muburyo butandukanye, nkamavuta yumukara, anticorrosive, hot-dip galvanised cyangwa ubukonje-galvanis. Ukurikije imikoreshereze yihariye ya X70 PSL2 spiral tube, turashobora gutanga inama nziza yo kuvura neza kubakiriya bacu bubahwa. Kurugero, igifuniko cya galvanised kumiyoboro ya X70 PSL1 yerekana kwihanganira ruswa.
