Nhau - Oiri Simbi Pipe: Zvishandiso, Properties, uye Common Size

Muindasitiri yakakura yemafuta,Mafuta mapaipi esimbi anoita basa rakakosha, achishanda sechinhu chakakosha mutakuri mukuendeswa kweoiri negasi rechisikigo kubva mukuchera pasi pevhu kusvika kune vashandisi. Kubva pakudhirowa muminda yemafuta negasi kusvika pakutakura pombi refu, mhando dzakasiyana dzeMafuta mapaipi esimbi, nemidziyo yavo yakasarudzika uye zvivakwa, inovimbisa kushanda kwakachengeteka uye kwakanaka kweiyo yese indasitiri cheni. Ichi chinyorwa chichatarisa pane kabhoni simbi pombi, seamless simbi pombi, uye API 5L simbi pombi (simbi pombi inosangana API 5L zviyero), kusanganisira yakajairika mienzaniso yakaita seAPI 5L X70 pombi, API 5L X60 pombi, uye API 5L X52 pombi, inopa yakadzama sumo yezvishandiso, zvivakwa, uye saizi yakajairikaMafuta mapaipi esimbi.

API 5L Pipe Iyo Yakakosha Pipeline Yekutakura Kwemagetsi

Kuongorora Zvinhu

1. Carbon Steel Pipe

Carbon simbi pombi chimwe chezvinhu zvinowanzoshandiswaMafuta mapaipi esimbi. Iyo inonyanya kuumbwa nesimbi uye kabhoni, ine mashoma manganese, silicon, sarufa, uye phosphorus. Carbon content inosarudza kusimba uye kusimba kwesimbi. Kazhinji kutaura, yakakwira kabhoni yemukati inowedzera simba resimbi, asi kuoma uye weldability zvinodzikira. Muindasitiri yemafuta, kabhoni simbi pombi inopa yakanakisa kuita kwese. Haisi chete ine simba rakakwirira rekumirisana nekumanikidzwa kwemafuta uye gasi ekufambisa, asi zvakare ine imwe nhanho yekuomesera kujairana neakaomesesa geological nharaunda. Uyezve, kabhoni simbi pombi ine mutengo wakaderera uye inopa yakanyanya kudhura-inoshanda, ichiita kuti ishandiswe zvakanyanya mumapombi emafuta negesi.

2. API 5L Steel Pipe Series Materials

API 5L Steel Pipe inogadzirwa zvinoenderana neiyo API 5L yakajairwa yakagadzwa neAmerican Petroleum Institute (API) uye inonyanya kushandiswa pamafuta negasi pombi. Iyi nhevedzano yepombi yesimbi inoiswa mumagiredhi akasiyana zvichienderana nekusimba kwesimbi, senge X52, X60, uye X70. Semuyenzaniso, API 5L X52 Pipe yakagadzirwa nepamusoro-simba yakaderera-alloy simbi. Pamusoro pezvinhu zvakakosha senge kabhoni nesimbi, ine zvakare alloying zvinhu zvakaita se niobium, vanadium, uye titanium. Kuwedzerwa kweaya alloying zvinhu kunowedzera zvakanyanya kusimba uye kusimba kwesimbi, ukuwo ichivandudza weldability yayo uye corrosion resistance. Izvo zvinhu zveApi 5l X60 Pipe uye Api 5l X70 Pipe inowedzerwazve optimized zvichibva pane iyi nheyo. Nekugadzirisa iyo alloying element reshiyo uye kupisa kupisa maitiro, simba resimbi uye kuita kwese kunowedzera kuwedzeredzwa, zvichiita kuti isangane nezvinodiwa zvekufambisa kwemafuta negasi pasi pekumanikidzwa kwepamusoro uye nemamiriro ekushanda akaomarara.

3. Seamless Simbi Pipe

Seamless simbi pombi inogadzirwa kuburikidza nematanho akadai senge perforation uye pombi rolling. Zvinhu zvayo zvakangofanana neambotaurwa kabhoni simbi pombi uye Api 5l akatevedzana simbi pombi, asi yakasarudzika maitiro ekugadzira kwayo inoipa yakasarudzika mabhenefiti. Seamless simbi pombi haina welds pamadziro ayo, zvichiita kuti yunifomu yose chimiro uye yakakwirira simba. Inogona kumirisana nedzvinyiriro dzepamusoro uye mamiriro ezvakatipoteredza akaomarara. Naizvozvo, inowanzoshandiswa muindasitiri yeoiri yezvishandiso zvinoda kushanda kwepamusoro, senge yakakwira-kudzvanywa mafuta uye gasi pombi nematsime.

Properties uye Hunhu

1. Simba

Simba chinhu chakakosha chepombi dzemafuta, zvichikanganisa kuchengetedzwa kwavo panguva yekufambisa oiri negesi. Iyo giredhi resimba re API 5l yakatevedzana mapaipi esimbi inoratidzwa nenhamba inotevera "X." Semuyenzaniso, X52 inoratidza simba shoma regoho re52 ksi (kilopounds per square inch), yakaenzana neanosvika 360 MPa mumamegapascals; X60 ine simba shoma regoho re60 ksi (inenge 414 MPa); uye X70 ine simba shoma regoho re70 ksi (inenge 483 MPa). Sezvo giredhi resimba rinowedzera, kudzvanywa kwepombi kunogona kumira kunowedzera zvinoenderana, kuchiita kuti ive yakakodzera mafuta uye gasi mapaipi ane zvinosiyana zvekumanikidza zvinodiwa. Seamless simbi pombi, nekuda kwechimiro chayo yunifomu uye kusimba kwakasimba kugovera, inoita zvirinani kana ichishingirira zvakanyanya.

2. Corrosion Resistance

Oiri uye gasi rekufambisa rinogona kunge riine corrosion media senge hydrogen sulfide uye carbon dioxide, saka pombi dzeoiri dzinofanirwa kunge dziine imwe nhanho yekuramba corrosion. Carbon simbi pombi ine huturu husina kusimba hwekurarisa, asi kushora kwayo kunogona kuvandudzwa nekuwedzera alloying zvinhu (senge chromium uye molybdenum muApi 5l akatevedzana) uye nekushandisa pamusoro peanti-corrosion marapirwo (sekupfeka uye plating). Kuburikidza nekugadzirwa kwezvinhu kwakakodzera uye kugadzirisa, Api 5l X70 Pipe, X60 Pipe, uye X52 Pipe, pakati pevamwe, chengetedza hupenyu hwakareba sevhisi munzvimbo dzinoparadza.

3. Weldability

Munguva yekuvakwa kwepombi yemafuta, pombi dzesimbi dzinofanirwa kubatanidzwa newelding, zvichiita kuti weldability ive hunhu hwakakosha hwepombi yesimbi pombi. Api 5l yakatevedzana simbi pombi yakanyatsogadzirirwa kuti yakanakisa weldability, kuve nechokwadi kusimba uye kusimba kwemajoini akasungwa. Welds dzemhando yepamusoro dzinogonawo kuwanikwa nekabhoni simbi pombi uye musono simbi pombi uchishandisa akakodzera welding matekiniki.

Dzidza zvakawanda nezve mashandisirwo emafuta casing, misiyano kubva kuAPI mapaipi, uye maficha

Common Sizes

1. Outer Diameter

Oiri pombi mapaipi esimbi anouya muhupamhi hwekunze kwemadhayamita kuti asangane nezvido zvekufambisa zvakasiyana. Common okunze dhayamita saizi nokuda Api 5L akatevedzana simbi pombi dzinosanganisira 114.3mm (4 inches), 168.3mm (6.625 inches), 219.1mm (8.625 inches), 273.1mm (10.75 inches), 323.9mm (12.75 inches), 35mm (416 in. inches), 457.2mm (18 inches), 508mm (20 inches), 559mm (22 inches), uye 610mm (24 inches). Iwo ekunze dhayamita saizi yemapombi esimbi isina musono akafanana neaya eApi 5L akatevedzana, asi asiri-akajairwa saizi anogona zvakare kugadzirwa kuti asangane nezvinodiwa nevatengi.

2. Kukora Kwemadziro

Kukora kwemadziro chinhu chakakosha chinokanganisa kusimba uye kutakura mutoro wepombi dzesimbi. Ukobvu hwemadziro epetroleum simbi mapaipi anosiyana zvichienderana nekumanikidzwa chiyero uye zvinodiwa zvekushandisa. Kutora API 5L X52 pombi semuenzaniso, kune yekunze dhayamita ye114.3mm, yakajairika madziro makobvu anosanganisira 4.0mm, 4.5mm, uye 5.0mm. Kune dhayamita rekunze re219.1mm, ukobvu hwemadziro hunogona kuita 6.0mm, 7.0mm, kana 8.0mm. API 5L X60 uye X70 mapaipi, nekuda kwekuda kwesimba rawo repamusoro, kazhinji ane madziro akakora kupfuura X52 mapaipi edhiyamita imwe yekunze kuti ive nechokwadi chakakwana uye kuchengetedzeka. Ukobvu hwemadziro hwepombi yesimbi isina musono inogona kunyatso dzorwa zvichienderana nemaitiro ekugadzira uye zvinodiwa nevatengi, kubva pa2mm kusvika makumi akati wandei emamirimita.

3. Kureba

Hurefu hwakaenzana hwepombi yepetroleum simbi inowanzoita 6 metres, 12 metres, nezvimwewo, kuitira nyore kutakura uye kuvaka. Mumashandisirwo chaiwo, kureba kwetsika kunogonawo kugadzirwa zvichienderana nezvinodiwa chaizvo zvepombi purojekiti, kuderedza pa-saiti yekucheka uye welding basa rekuita uye nekuvandudza kugona kwekuvaka.

Muchidimbu, zvinhu, zvivakwa, uye zvakajairwa zviyero zveMafuta mapaipi esimbi zvinhu zvakakosha mukugadzira uye kushandiswa kwavo. Carbon Simbi Pipe, Seamless Simbi Pipe, uye simbi pombi muApi 5l Simbi Pipeakatevedzana, akadai seX70, X60, uye X52, imwe neimwe inoita basa rakakosha munzvimbo dzakasiyana dzeiyoMafuta indasitiri nekuda kwemabhenefiti avo akasiyana. Nekuenderera mberi kwekuvandudzwa kweMafuta indasitiri, kuita uye mhando zvinodiwa kutiMafuta mapaipi esimbi ari kuramba achioma. Mune ramangwana, kuwedzera kwepamusoro-kuitaMafuta mapaipi esimbi achagadzirwa uye anoshandiswa kuti asangane nezvinodiwa zvemamiriro ekushanda akaoma uye kure-kure, kutakura kwepamusoro.
