API 5L kazhinji inoreva chiyero chekushandisa kwepombi simbi mapaipi, ayo anosanganisira maviri makuru mapoka:mapaipi esimbi asina musonouyewelded simbi pombi. Parizvino, inowanzoshandiswa welded simbi pombi mhando muoiri mapaipi varispiral undermerged arc welded pombi(SSAW PIPE),longitudinal pasi pemvura arc welded mapaipi(LSAW PIPE), uyemagetsi kuramba welded pombi(ERW). Mapombi esimbi asina musono anowanzo kusarudzwa kana dhayamita yepombi isingasviki 152mm.
Iyo yenyika standard GB/T 9711-2011, Simbi Pipes for Pipeline Transportation Systems muPetroleum uye Natural Gas Industries, yakagadzirwa zvichibva paAPI 5L.
GB/T 9711-2011 inotsanangura zvinodikanwa zvekugadzira zvemapombi esimbi asina musono uye akasungwa anoshandiswa mupetroleum uye gasi rechisikigo pombi yekufambisa masisitimu, inovhara maviri echigadzirwa mazinga (PSL1 uye PSL2). Naizvozvo, chiyero ichi chinoshanda chete kune isina musono uye yakashongedzwa mapaipi esimbi ekufambisa kwemafuta uye gasi uye haishande pamapombi esimbi.
Simbi MaGrade
API 5L mapaipi esimbi anoshandisa akasiyana siyana magiredhi emhando anosanganisira GR.B, X42, X46, X52, X56, X60, X70, X80, nezvimwe. Pipeline simbi dzine mamakisi X100 uye X120 zvino dzakagadzirwa. Magiredhi esimbi akasiyana anoisa zvinodiwa zvakasiyana pane zvigadzirwa uye maitiro ekugadzira.
Quality Levels
Mukati meiyo API 5L yakajairwa, pombi simbi mhando yakakamurwa sePSL1 kana PSL2. PSL inomirira Product Specification Level.
PSL1 inotsanangura zvakajairika zvinodiwa zvepiipi simbi; PSL2 inowedzera zvinosungirwa zvinodiwa zvemakemikari kuumbwa, notch kusimba, simba zvivakwa, uye yekuwedzera NDE kuyedzwa.
