API 5Lkazhinji inoreva pombi yesimbi pombi (pipeline pombi) yekuitwa kweiyo mwero, pombipombi yesimbikusanganisira musono simbi pombi uye welded simbi pombi mapoka maviri. Parizvino mupombi yemafuta isu tinowanzo shandisa welded simbi pombi pombi mhando spiral yakanyura arc welded pombi (SSAW), musono wakatwasuka wakanyura arc welded pombi (LSAW), pombi yekudzivirira welding (ERW), pombi yesimbi isina musonoinowanzo shandiswa mudhayamita yepombi isingasviki 152mm.
Iyo yenyika standard GB/T 9711-2011 simbi pombi yepombi yekufambisa sisitimu muindasitiri yemafuta negasi inoumbwa zvinoenderana neAPI 5L.
GB/T 9711-2011 inotsanangura zvinodikanwa zvekugadzira zvemapombi esimbi asina musono uye akashongedzerwa emazinga maviri echigadzirwa (PSL1 nePSL2) yemapombi ekufambisa masisitimu muindasitiri yemafuta negasi. Naizvozvo, chiyero chinongoshanda kune isina musono pombi dzesimbi uye welded simbi pombi dzekutakura oiri uye gasi, uye haishande kukanda mapaipi esimbi.
Simbi MaGrade
Magiredhi esimbi ezvigadzirwa zvemapombi esimbi eiyi API 5L chiyero ndeye GR.B, X42, X46, X52, X56, X60, X70, X80, nezvimwewo. Magiredhi esimbi emapombi esimbi akasiyana, uye zvinodiwa zvezvinhu zvakasvibirira. uye kugadzirwa kwakasiyanawo, asi iyo kabhoni yakaenzana pakati peakasiyana simbi mamakisi inodzorwa zvakanyanya.
Hunhu hwemhando
Mune iyo API 5L pombi mwero, zviyero zvemhando (kana zvinodiwa) zvepombi yesimbi zvakakamurwa kuita PSL1 uye PSL2. PSL chidimburidzo chedanho rekutsanangurwa kwechigadzirwa.
PSL1 inopa huwandu hwehuwandu hwemhando yepombi zvinodiwa; PSL2 inowedzera zvinosungirwa zvinodiwa zvemakemikari kuumbwa, notched kuoma, simba zvivakwa, uye mamwe maNDE.
