Kushandiswa kwakakura kwepombi dzesimbi dzisina musono mumaindasitiri uye minda yekuvaka inoita kuti zviyero zvayo uye zvinodiwa zvemhando zvive zvakakosha. Iyo inonzi "three-standard pombi" inoreva mapaipi esimbi asina musono anosangana nezviyero zvitatu zvepasi rose, kazhinji kusanganisira.API(American Petroleum Institute),ASTM(American Society for Testing and Materials) uyeASME(American Society of Mechanical Engineers) zviyero. Iyi mhando yepombi yesimbi ine yakanyanyisa kuvimbika uye kuchinjika nekuda kwemazinga ayo epamusoro uye akawanda certification, uye inoshandiswa zvakanyanya mumaindasitiri akadai seoiri, gasi rechisikigo, makemikari, uye magetsi.

Chekutanga, API yakajairwa seamless simbi mapaipi anonyanya kushandiswa muindasitiri yemafuta negasi, uye zviyero zvayoAPI 5LuyeAPI 5CT. Iyo API 5L yakajairwa inovhara zvinodiwa zvekugadzira zvemapaipi ekutepfenyura kuti ive nechokwadi chekuita kwepombi mukumanikidza kwakanyanya, tembiricha yepamusoro uye nharaunda dzinoparadza. Iyo API 5CT chiyero inotarisana nemafuta casing uye tubing kuve nechokwadi chekusimba uye kusimba kwemapaipi panguva yekuchera nekugadzira. API yakajairwa seamless simbi mapaipi anowanzo ane simba rakakwirira, kusimba kwepamusoro uye kunaka kwekusagadzikana.

Kechipiri, ASTM yakajairwa seamless simbi pombi inovhara akawanda maindasitiri minda, kusanganisira boilers, kupisa exchanger, zvivakwa zvekuvaka, nezvimwe.ASTM A106uyeASTM A53 ndiwo maitiro anomiririra. ASTM A106 seamless simbi pombi inokodzera kushandiswa kwepamusoro-tembiricha uye inoshandiswa zvakanyanya mumhando yepamusoro-yepiping masisitimu mumagetsi emagetsi, ekunatsa uye zvidyarwa zvemakemikari. ASTM A53 isina musono simbi pombi inokodzera zvakajairwa-chinangwa chekufambisa mvura, kusanganisira mvura, mweya uye chiutsi. Aya mazinga anonyatso tsanangura kuumbwa kwemakemikari, zvivakwa zvemuchina uye kushivirira kwepaipi yesimbi kuti ive nechokwadi chekuvimbika kwavo mukushandisa kwakasiyana.

Chekupedzisira, ASME yakajairwa seamless simbi mapaipi anonyanya kushandiswa kune boilers uye kumanikidza midziyo. ASME B31.3 uye ASME B31.1 zviyero zviviri zvakakosha zvinotsanangura dhizaini nekugadzira zvinodiwa zvepombi masisitimu pasi pekumanikidzwa kwakanyanya uye tembiricha yepamusoro. Iyo ASME chiyero inosimbisa kuchengetedzeka uye kushanda kwenguva refu kwepombi dzesimbi uye inokodzera zviitiko zvinoda kuvimbika kwakanyanya uye kuchengetedzeka, senge zvidyarwa zvemagetsi enyukireya, zvidyarwa zvemakemikari uye midziyo mikuru yemaindasitiri.

Iyo mukana wemapombi matatu-akajairwa ari mune yavo yakawanda certification uye yakafara kushanda. Nemhaka yokuti vanosangana ne API, ASTM uye ASME zviyero panguva imwe chete, rudzi urwu rwepombi yesimbi isina musono inogona kusangana nezvinodiwa zvakasimba zvenyika dzakasiyana nematunhu uye inokodzera zvakasiyana-siyana zvekushanda zvakaoma. Ingave mukumanikidza kwakanyanya, tembiricha yakakwira kana nharaunda inoora, mapaipi matatu-akajairwa anogona kuratidza kuita kwakanakisa kuve nechokwadi chekuchengetedza uye kugadzikana kushanda kwehurongwa.

Muchidimbu, sechigadzirwa chepamusoro-soro pakati pepombi dzesimbi dzisina musono, mapaipi matatu akajairwa ave chinhu chakakosha uye chakakosha muindasitiri nekuvaka minda ine akawanda chiyero certification uye kuita kwakanakisa. Kushandiswa kwaro kwakakura hakusi kungovandudza kunaka uye kuchengetedzeka kwemapurojekiti, asiwo kunosimudzira kusimudzira uye kuvandudzwa kwesimbi yezvinhu tekinoroji. Kusarudza matatu-yeyero mapaipi haisi kungoita chivimbiso chemhando, asiwo kuzvipira kune kugadzikana kwenguva refu uye kuchengetedzwa kweprojekiti.
