Ivalvu
Umhlinzeki Wakho Ochwepheshe
I-Octal Pipe ingumphakeli ochwepheshe futhi ohlanganisiwe wemikhiqizo ye-oilfield nezixazululo zensimbi zezimboni ezinze eChina. Ngolwazi olubanzi ekuhlinzekeni, ekusabalaliseni, nasekukhiqizeni, sisebenza ngokukhethekile ekuhlinzekeni ngezinhlobonhlobo zezinto zensimbi zemikhakha kawoyela negesi, amandla, kanye nezimboni.
Kungani Khetha Thina
Ukuqinisekiswa Kwekhwalithi Ephakeme
Amapayipi ethu ensimbi ahlolwa kanzima futhi anamathela ezindinganisweni zamazwe ngamazwe, ukuqinisekisa ukuqina okungenakuqhathaniswa, ukumelana nokugqwala, nokusebenza ezimeni ezimbi kakhulu.
Izitifiketi
Wonke umkhiqizo usekelwa ukulandeleka okugcwele kwempahla, izitifiketi zokugaya, nokuhambisana nezindinganiso zamazwe ngamazwe njenge-API, ASTM, ASME, EN, ne-ISO.
Amanani Wokuncintisana
Siletha amapayipi ensimbi{0}ezinga le-premium{0}}ngezindleko ezifanele, sikhulisa inani ngokukhiqiza okuphumelelayo nokuphathwa kochungechunge lokuhlinzeka ngaphandle kokuyekethisa ikhwalithi.
Ukulethwa Okusheshayo Nokwethembekile
Ngokusebenzisa kahle ukuthunyelwa kwempahla yasolwandle kanye nenethiwekhi yomhlaba wonke, siqinisekisa ukuthunyelwa kwasolwandle okufika ngesikhathi kwamapayipi ensimbi, sinciphisa ukubambezeleka kanye nokugcina ukusebenza kwezimboni zakho kusesikhathini.

Izici ezibalulekile ze-API 6D
Idizayini ephelele ye-Bore
I-API 6D iyalela-izimbobo ezigcwele ukuze kuhlaliswe izingulube ezisetshenziswa ekuhlanzeni nasekuhloleni amapayipi. Lo mklamo uqinisekisa ukudlula okungavinjelwe kwezingulube, okubalulekile ekugcineni ukusebenza kahle kwamapayipi kanye nokuvimbela ukuvinjelwa.
Izidingo Zokuphepha Ezithuthukisiwe
Izinga lihlanganisa izidingo eziqinile zezindlela zokunciphisa ingcindezi{0}}. Amavaluvu kufanele abe nokukhululeka kokucindezela komgodi okuzenzakalelayo ukuze kuvinjelwe uketshezi oluvaleleke ekubangeleni ukucindezela okuyingozi{2}}okungase kweqe isilinganiso sokucindezela kwevalvu.
Ukuphepha Komlilo
I-API 6D ibeka phambili imiklamo{1}}ephephile yomlilo. Amavalvu kufanele ahlanganise isihlalo sensimbi sesibili esisebenza uma isihlalo esithambile sokuqala sihluleka ngesikhathi somlilo. Lokhu kuqinisekisa uphawu oluqinile ngisho nangaphansi kwezimo ezimbi kakhulu, kuvikela ipayipi nendawo elizungezile.
Izinqubo Zokuhlola Eziqinile
I-API 6D idinga igobolondo le-hydrostatic, isihlalo, ukuhlolwa kwe-backseat, nokuhlolwa okuqondile kwe-drift yesango nama-valve epulaki. Lezi zivivinyo eziqinile ziqinisekisa ukuthi ama-valve angakwazi ukumelana nezingcindezi zokusebenza, amazinga okushisa, nezinselele zemvelo ezihlukile kumapayipi.
Amazinga Ezinto Ezikhethekile
I-API 6D icacisa izidingo zezinto ezibonakalayo ukuze kuqinisekiswe ukuqina nokuhambisana ne-petroleum negesi yemvelo. Ibhekisela ezintweni ezifanele -eziphezulu nezindawo zokushisa{3}eziphezulu.

Amathiphu Awusizo Wokuhlonza
Hlola Izimpawu
• I-API 6D: Bheka amamaki akhombisa ukuthobela i-API 6D, okuhlanganisa nenombolo evamile, isilinganiso sokucindezela, nokokusebenza.
• I-API 600: Bheka amamaki akhombisa ukuthobela i-API 600, okuhlanganisa nenombolo evamile, isilinganiso sokucindezela, nokokusebenza.
Qinisekisa Amadokhumenti
• I-API 6D: Qinisekisa ukuthi ivalvu iza nemibhalo enemininingwane ehlanganisa amarekhodi okukhiqiza, imiphumela yokuhlolwa, nezitifiketi.
• I-API 600: Qinisekisa ukuthi ivalvu iza namadokhumenti ahlanganisa amarekhodi okukhiqiza, imiphumela yokuhlolwa, nesitifiketi, okuqinisekisa ukuthobelana ne-API 600.
Hlola i-Valve Design
• I-API 6D: Hlola idizayini yevalvu ukuze uqinisekise ukuthi iyahlangabezana nezidingo zohlobo oluthile lwevalvu (isb., ivalvu yebhola, ivalve yesango).
• I-API 600: Hlola idizayini yevalvu yesango ukuze uqinisekise ukuthi ihlangabezana nezidingo ezinemininingwane ezicaciswe ku-API 600.
Amazinga Wokuklama kanye Nokukhiqiza
Izidingo Zomklamo
Ukucaciswa kwedizayini ku-API 6D kuqinisekisa ukuthi amavalvu afanele inhloso ekufakweni kwamapayipi. Umklamo kufanele uvumele ukusebenza okuthembekile ngaphansi kwezimo ezihlukahlukene zokusebenza ezifana nezingcindezi ezinkulu namazinga okushisa. Izici ezibalulekile ezicatshangelwayo zifaka uhlobo lwe-valve, usayizi, nezinto ezibonakalayo, kugxilwe ekuqineni nasekuphepheni. Amavalvu kufanele futhi ahambisane nemibandela yokulawula ukugeleza esiza ukulawula ukunyakaza koketshezi, ukuqinisekisa ukuthi angakwazi ukubhekana nokucindezela, izici zamakhemikhali, nezinselele zemvelo zokusebenza kwamapayipi.
Amazinga Okukhiqiza
Ukukhiqiza ngaphansi kwe-API 6D kudinga ukulawulwa kwekhwalithi okuqinile nokuhambisana namazinga omhlaba. Wonke ama-valve kufanele enziwe kusetshenziswa amasu anembayo aqinisekisa ukunemba nokungaguquguquki kubukhulu be-valve nokusebenza. Inqubo yokukhiqiza ihlanganisa nokuhlolwa okubanzi, okufana nokucindezela nokuhlola ukuvuza, ukuze kuqinisekiswe ukuthi ivalvu ngayinye isebenza kahle ngaphambi kokuba isetshenziswe ohlelweni lwamapayipi.
Izilinganiso Zengcindezi Nezinga Lokushisa
Izilinganiso Zengcindezi Nezinga Lokushisa zamavalvu ambozwe ngaphansi kwe-API 6D zincike ezintweni ezihlukahlukene, okuhlanganisa uhlobo lwevalvu, into esetshenzisiwe, kanye nohlelo oluthile. Ngezansi ukubuka konke okuvamile nedatha evamile esekelwe kumazinga omkhakha:
Isilinganiso Sokucindezela
● Isilinganiso sokucindezela kwe-valve sibhekisela ekucindezelweni okuphezulu i-valve engakwazi ukuyiphatha ngokuphephile ezingeni lokushisa elithile ngaphandle kokuphazamisa ubuqotho bayo besakhiwo noma ukusebenza kokuvala.
● Kumavalvu e-API 6D, izilinganiso zokucindezela zihlukaniswa ngezigaba zokucindezela (amakilasi e-ANSI), ngokuvamile asukela ku-150 kuya ku-2500. Lesi sigaba sinquma ingcindezi yokusebenza evumelekile ye-valve ngokusekelwe ekwakhiweni kwayo nokokusebenza.
Izibonelo Zekilasi Lokucindezela
● Isigaba 150: Isetshenziselwa amasistimu okucindezela okuphansi, ngokuvamile kufika ku-285 psi (amaphawundi ngeyintshi yesikwele).
● Ikilasi 300: Iphatha ingcindezi efika ku-740 psi.
● Isigaba 600: Ilinganiselwe kumasistimu asebenza ku-1480 psi.
● Ikilasi 1500: Ilinganiselwe ngengcindezi efika ku-4450 psi.
● Ikilasi 2500: Iphatha izingcindezi ezifika ku-7400 psi.
Ukucaciswa Kwempahla
Izinto ezisetshenziselwa amavalvu e-API 6D kumele zihambisane nesethi yezinkombandlela ezithile eziqinisekisa ukuqina namandla. Ukucaciswa kwezinto ezibalulekile zifaka:
Izinto Zomzimba Nebhonethi:Imizimba yamavalvu namabhonethi kumele enziwe ngezinto ezikwazi ukumelana nokucindezela kwangaphakathi kanye nezimo zemvelo. Izinto ezivamile zihlanganisa izinsimbi ze-carbon, izinsimbi ezingenasici, nezinsimbi ze-alloy. Ukukhethwa kwezinto ezibonakalayo kuncike kusayizi we-valve, isigaba sokucindezela, nezinga lokushisa lokusebenza.
Izinto zokuvala:Izinto zokuvala kumavalvu e-API 6D, okuhlanganisa ama-gaskets, izimpawu, nokupakisha, zenzelwe ukuvimbela ukuvuza ngaphansi kwengcindezi ephezulu. Lezi zinto kufanele zihlangabezane nokuphikiswa kwamakhemikhali kanye nezidingo zokubekezelela izinga lokushisa ezichazwe yi-valve yesicelo esihlosiwe.
I-Bolting ne-Fasteners:I-bolting esetshenziswa kumavalvu e-API 6D kufanele ihambisane namazinga angeziwe, njenge-API 20E yensimbi ye-carbon kanye ne-API 20F ye-corrosion{3}}bolting engavimbeli. I-bolting iqinisekisa ubuqotho besakhiwo ngaphansi kwezimo zengcindezi enkulu futhi kufanele ithathwe kubakhiqizi abaqeqeshiwe.
Sika Izinto:Sika izingxenye ezifana nezihlalo, iziqu, namadiski ngokuvamile enziwa ngezinto ezifana nensimbi engagqwali noma ama-alloys aphezulu ukuze kuqinisekiswe ukumelana nokuguga, ukugqwala, namazinga okushisa aphezulu.
-Imingcele Engenayo Ingcindezi:Izingxenye ezifana nezisekelo, okunamathiselwe kwi-actuator, nezisekeli aziyona ingxenye yomngcele wengcindezi kodwa kusafanele zenziwe ngezinto ezihlala isikhathi eside ukuze zisekele ukusebenza nokuthembeka kwevalvu.
