Seamless simbi pombi API5L GRB inowanzoshandiswa simbi pombi zvinhu, kunyanya kushandiswa oiri, gasi uye mamwe maindasitiri. Yayo "API5L" chiyero chakagadzirwa neAmerican Petroleum Institute, uye "GRB" inoratidza giredhi uye rudzi rwezvinhu, izvo zvinowanzo shandiswa pakumanikidza pombi. Mukana wepombi dzesimbi dzisina musono uri mumichina yavo yakanakisa uye corrosion resistance, uye vanogona kushanda zvakadzikama munzvimbo dzakaoma dzine tembiricha yepamusoro uye kudzvanywa kwakanyanya.

Iwo makuru emakemikari zvikamu zve API5L GRB seamless simbi mapaipi anosanganisira kabhoni, manganese, sarufa, phosphorous, nezvimwewo, uye vane yakanaka weldability uye plastiki mushure mekunyatsopisa kupisa maitiro. Rudzi urwu rwepombi yesimbi inowanzoshandiswa kutakura zvinwiwa uye magasi, kunyanya mukushandiswa uye kutakura minda yemafuta negasi, kuve nechokwadi chekuchengetedza uye kushanda zvakanaka.

ASTM A53, ASTM A106uyeAPI 5Lzvinhu zvitatu zvakajairika simbi musono pombi mipimo, imwe neimwe yakakodzera akasiyana chikumbiro zviitiko.

Iyo ASTM A53 chiyero inonyanya kushandiswa muminda senge simba, kuvaka uye petrochemicals. Iyo pombi yesimbi yeiyi chiyero inokodzera yakaderera kudzvanywa uye yakadzika tembiricha nharaunda, uye inowanzoshandiswa kutakura mvura, gasi uye zvimwe zvinwiwa. Iine simba rakanaka uye weldability, uye yakakodzera kugadzira mapaipi akasiyana-siyana uye zvikamu zvemaitiro.

Iyo ASTM A106 yakajairwa inotarisa zvakanyanya pane yakanyanya tembiricha uye yakanyanya kudzvanywa maapplication uye inokodzera indasitiri yemafuta negesi. Mapombi esimbi asina musono eiyi chiyero anonyanya kushandiswa kutakura chiutsi, mvura inopisa nemafuta. Vanogona kuchengetedza zvakanaka mechanical properties pakupisa kwepamusoro kuti vave nechokwadi chekuchengeteka uye kugadzikana kwepombi.

Iyo API 5L yakajairwa yakagadzirirwa indasitiri yemafuta uye gasi uye yakakodzera kune yakakwirira-kumanikidza kutapurirana mapaipi. Mapaipi esimbi asina musono anosangana nechiyero ichi ane yakanakisa corrosion resistance uye pressure resistance, inova nechokwadi chekushanda kwakachengeteka pasi pemamiriro akanyanya. API 5L mapaipi anowanzo shandiswa mukushandiswa uye kutakura mafuta uye gasi minda kuti ive nechokwadi chekufambisa kwakanaka kwemvura.

Iyi miyero mitatu yemapombi esimbi isina musono ane hunhu hwayo, anofukidza akasiyana ekushandisa mamiriro kubva kuderera kudzvanya kusvika pakumanikidzwa kukuru, kubva pakadzika tembiricha kusvika kune yakanyanya tembiricha, kusangana nezvinodiwa zvemaindasitiri zvakasiyana, uye kupa vimbiso yekuchengeteka nekubudirira.
