Amathebula esisindo samapayipi kanye namathebula eshejuli ahlinzeka ngedatha yokubhekisela ejwayelekile yokukhetha nokusebenzisa amapayipi, okwenza umklamo wobunjiniyela ube nembambe futhi usebenze kahle.

Imvelaphi Yamathebula Esisindo Sepayipi Lensimbi Ejwayelekile Yekhabhoni
Izindinganiso eziyinhloko zesisindo sobukhulu bepayipi lensimbi yekhabhoni yi-ISO 4200, EN 10220, ASME B36.10M, kanye ne-ASTM A53/A53M.
Nakuba indinganiso ye-API 5L inganikezi ithebula elithile lezisindo zamapayipi, amanothi eThebula 9 abonisa ukuthi amanani ajwayelekile obubanzi obucacisiwe bangaphandle kanye nobukhulu bodonga lwepayipi lensimbi kubhekiselwa ku-ISO 4200 kanye ne-ASME B36.10M.
Ukuqhathanisa Izindinganiso Zesisindo Sepayipi Lensimbi Yekhabhoni
Izindinganiso ezahlukene zingase zinikeze amathebula athile ezisindo zezinhlelo zokusebenza ezahlukene kanye nezinhlobo zezinto zokwakha.
Indlela Yokubala Isisindo Sepayipi
Indlela Yokubala Isisindo Sepayipi Lensimbi inikeza indlela elula yokubala isisindo sepayipi lensimbi, okwenza kube nokwenzeka ukunquma ngokushesha isisindo esiphelele sezinto ezidingekayo, ngaleyo ndlela kuncishiswe izindleko ezingadingekile. Ngale ndlela, isisindo sepayipi lensimbi singalinganiswa ngokusekelwe kububanzi balo, ukujiya kodonga, kanye nobude balo, okubaluleke kakhulu ekuhleleni ezokuthutha, ukuklama izakhiwo zokusekela, kanye nokulinganisa izindleko. Ukubala isisindo okunembile nakho kusiza ukuqinisekisa ukuphepha kwesakhiwo nokuvimbela ukwehluleka kwesakhiwo ngenxa yokulayisha ngokweqile.
Ifomula yesisindo sepayipi lensimbi yekhabhoni iyafana kakhulu ezindinganisweni ezahlukene, kunomehluko omncane kuphela ezifinyezweni.

Cingu-0.0246615 yokubala kumayunithi e-SI kanye no-10.69 wokubala kumayunithi e-USC.
QAPHELA: I-API 5L inenani elingu-0.02466 ekubalweni kumayunithi e-SI.
U-0.0246615 kanye no-0.02466 bamele umehluko omncane kumanani athathwe ekubalweni kwesisindo. Lo mehluko, nakuba umncane, ungaba nomthelela lapho kwenziwa izibalo ezinembile kakhulu. Ngokuvamile, lo mehluko ngeke ube nomthelela omkhulu kuzinhlelo zokusebenza eziningi zobunjiniyela nezokwakha, kodwa lapho kudingeka khona ukunemba okuphezulu, inani lokunemba elifanele kufanele likhethwe ngokwesidingo esithile.
Incazelo Yeshejuli Yamapayipi Ensimbi
Luhlelo lwezinombolo olujwayelekile olusetshenziselwa ukuveza ubukhulu bodonga lwamapayipi ensimbi, olunikeza ireferensi efanayo yobukhulu bamapayipi ukuze kuhambisane nezimo ezahlukene zokucindezela kanye nokushisa.
Ngokuqondile, uma inombolo "yeShejuli" iphakeme, ubukhulu bodonga lweshubhu buyanda, futhi ngokufanele, ingcindezi yangaphakathi ishubhu ingamelana nayo inkulu. Isibonelo, iShejuli 40 iyilungiselelo lobukhulu bodonga oluphakathi elisetshenziswa kabanzi ekusetshenzisweni kokucindezela okuphansi kuya kokuphakathi, kuyilapho iShejuli 80 inobukhulu bodonga obukhulu ezindaweni ezinokucindezela okuphezulu.
Lokhu kuhlukaniswa kwasungulwa ekuqaleni ukuze kube lula inqubo yokuklama nokukhiqiza amapayipi ezimboni ngokubeka amazinga obukhulu bodonga ajwayelekile, okwenza kube lula konjiniyela ukukhetha amapayipi afanele indawo yabo yokusebenza. Amazinga ahlukahlukene eShejuli athuthukiswe kucatshangelwa izici ezahlukahlukene, kufaka phakathi izakhiwo zemishini zezinto ezisetshenziswayo, ukucindezela kanye namazinga okushisa ngaphansi kwezimo zokusebenza, kanye nohlobo loketshezi.
Umthombo Wedatha Yeshejuli Yepayipi Lensimbi Yekhabhoni
KuShejuli Yepayipi i-ASME B36.10 kanye neThebula le-ASTM A53 2.2 (Isiphelo Esicacile) okungukuthi, inani liyafana.
Kodwa-ke, ngenxa yomehluko ekucutshungulweni kwesiphelo sepayipi i-ASTM A53 Table 2.3 (Enemicu Nehlanganisiwe) amanani azohluka.
Ithebula le-ASTM A53 2.3 (Elinezintambo Nelihlanganisiwe) Isheduli 30, 40, 60, kanye no-80 kuphela. Embuzweni weSheduli Yepayipi, qaphela i-Distinction.
Ukuhlukaniswa Kweshejuli
ishejuli 5, ishejuli 10, ishejuli 20, ishejuli 30, ishejuli 40, ishejuli 60, ishejuli 80, ishejuli 100, ishejuli 120, ishejuli 140, ishejuli 160.
Ishejuli 40 kanye neShejuli 80 yizona zigaba ezivame kakhulu zobukhulu bodonga lwamapayipi ezindaweni ezinomfutho ophansi kuya kophakathi kanye nezinomfutho ophezulu, ngokulandelana.

Singomunye wabakhiqizi nabahlinzeki bepayipi lensimbi elihlanganisiwe lekhabhoni kanye namapayipi ensimbi angenamthungo abavela eShayina, sinezinhlobonhlobo zamapayipi ensimbi asezingeni eliphezulu esitokweni, sizibophezele ekukunikezeni uhla oluphelele lwezixazululo zamapayipi ensimbi. Ukuze uthole imininingwane eyengeziwe yomkhiqizo, sicela ukhululeke ukuxhumana nathi, silangazelela ukukusiza ukuthola izinketho zamapayipi ensimbi ezingcono kakhulu ezifanela izidingo zakho!
amathegi: ishadi lesisindo sepayipi, ishejuli, ishejuli 40, ishejuli 80, abahlinzeki, abakhiqizi, amafektri, abathengisi bamasheya, izinkampani, ukuthengisa ngobuningi, ukuthenga, intengo, ikhotheshini, inqwaba, yokuthengisa, izindleko.
