Seamless Steel pombi Api5l GRB chinhu chinowanzoshandiswa simbi pombi yezvinyorwa, inoshandiswa zvakanyanya mumafuta, gasi uye mamwe maindasitiri. Its "api5l" chiyero chakagadzirwa neAmerican Petrleum Institute, uye "grb" inoratidza giredhi uye rudzi rwezvinyorwa, izvo zvinowanzoshandiswa pombi dzekumanikidza. Kubatsira kwesimbe yeSimbi iri mune yavo yakanakisa manhamba emagetsi uye kupokana, uye vanogona kushanda nesimba munzvimbo dzine hutsinye nekudzvinyirira kwakanyanya uye nekumanikidza kwakanyanya.

Izvo zvakakosha zvemakemikari zveApi5l GRB Seamless Simbi mapepa anosanganisira kabhoni, manganse, sulfur, phasporous, etcasticus uye epurasitiki uye plasikiridzo mushure mekupururudza kwakasimba kurapa kwekurapa. Rudzi urwu rwesimbi rwiyo runowanzoshandiswa kutakura zvinwiwa nemagasi, kunyanya mukushusha uye kufambisa kweminda yeoiri negesi, kuve nechokwadi chekuchengetedza uye kushanda zvakanaka.

ASTM A53, ASTM A106uyeAPI 5LNdezvevatatu zvakajairika zvisingachinguhupamisa pombi zviyero, imwe neimwe yakakodzera kune akasiyana mashandiro ekushandisa.

Iyo ASTM A53 chiyero chinonyanya kushandiswa muminda yakadai sesimba, kuvaka uye prirochemal. Iyo pombi yesimbi yeichi chiyero yakakodzera kudzvinyirira yakaderera uye nzvimbo dzakaderera tembiricha, uye kazhinji inoshandiswa kutakura mvura, gasi uye mamwe mvura. Iyo ine simba rakanaka uye wolcability, uye yakakodzera kugadzira matipi akasiyana siyana uye zvikamu zvivakwa.

Iyo ASTM A106 yakajairwa inotarisa zvakanyanya pane yakakura tembiricha uye yakanyanya kudzvinyirira mafomu uye yakakodzera kune indasitiri yemafuta negesi. Iyo isina maaMusiniki zvibayiro zvezviyero izvi zvinonyanya kushandiswa pakufambisa kweSteam, mvura inopisa nemafuta. Ivo vanogona kuchengetedza yakanaka michina yezvimiro pakupisa kwakanyanya kuti uve nechokwadi chekuchengetedza uye kugadzikana kwepombi.

Iyo API 5l chiyero chakagadzirirwa iyo Mafuta negesi indasitiri uye yakakodzera kune yakakwirira-kumanikidza transmination pombi. Pipisi yesimbi yesimbi iyo inosangana neyakagadziro ine zvakanakisa kurwisa uye kumanikidza kuramba, kunoita kuti kushanda kwakachengeteka mumamiriro ezvinhu akanyanya. API 5L mapuripi anowanzo shandiswa mukubiridzira uye kufambisa kweminda yemafuta negesi kuti ive nechokwadi chekufambisa zvakanaka kwemvura.

Izvi zviyero zvitatu zvemabheji echiSimbi ane maitiro avo, achifukidza mamiriro ekunyorera kubva mukudzvinyirira kudzvinyirira, kubva mukudziya kwakadzika kusvika pakudzvinyirira.
