Amandla kanye nokwethenjwa kwamapayipi ahlelekile ahlukaniswayo: Ukubukeka okujulile ePipe Fered Subled Fered Pipe ne-API 5L Line Pipe
Yethula:
Emhlabeni wokuthuthukiswa kwezokwakha nokuthuthuka kwengqalasizinda, ukukhetha izinto ezifanele kubalulekile.I-ALELLOBT PASTIAL PIPES dlala indima ebalulekile ekunikezeni amandla, ukuqina kanye nokwethenjwa kumaphrojekthi ahlukahlukene. Kule bhulogi, sizohlola izici nezinzuzo zezinhlobo ezimbili ezibalulekile zepayipi lesakhiwo: uPiral Subled Piple we-arc welded and API 5L Line Pipe.
Kuvunguza ipayipi le-arc egxilile
I-WELD engenisiwe ye-arc (saw) ipayipi, eyaziwa nangokuthi ipayipi le-SSAW, isetshenziswa ezinhlobonhlobo zezicelo. Isici esiyingqayizivele seIpayipi le-SSAW Ingabe ama-seams awo okuvunguza, anikeza amandla amakhulu namandla okuthwala umthwalo ngokuqhathaniswa nezinye izinhlobo zepayipi. Lo mklamo oyingqayizivele usiza ukusabalalisa ukucindezela ngokulinganayo kulo lonke ipayipi, okwenza kube kuhle ngamaphrojekthi adinga ubuqotho bezinhlekelele.

Ukuhlolwa kweHydrostatic
Ipayipi lizomelana nokuhlolwa kwe-hydrostatic ngaphandle kokuvuza ngomthungo we-weld noma umzimba wepayipi
Ama-pailers akudingeki ahlolwe ngokuqinile, uma nje izingxenye zepayipi elisetshenziselwa ukumaka amajoyidi ahlolwe ngempumelelo ngempumelelo yokusebenza.
Ukulandelwa:
Nge-PSL 1 Ipayipi, umenzi uzosungula futhi alandele izinqubo ezibhaliwe zokugcina:
Ubunikazi bokushisa kuze kube yilapho kwenziwa izivivinyo ze-Chmical ngayinye futhi zivumelana nezidingo ezicacisiwe
Umazisi we-test-unit kuze kube yilapho kwenziwa izivivinyo ngakunye kwemishini futhi kuvumelana nezidingo ezichaziwe zikhonjiswa
Ngepayipi le-PSL 2, umenzi uzosungula futhi alandele izinqubo ezibhaliwe zokugcina ubunikazi bokushisa kanye nobunikazi bokuhlolwa kwepayipi elinjalo. Izinqubo ezinjalo zizohlinzeka ngezindlela zokulandela noma yibuphi ubude bepayipi kuyunithi elifanele lokuhlola kanye nemiphumela yokuhlolwa kwamakhemikhali ehlobene.
Enye yezinzuzo eziphambili ze-SSAW Pipe ukukhiqiza kwayo ukuguquguquka. Lawa mapayipi akhiqizwa ngosayizi ahlukahlukene, amadayimane nobukhulu futhi angenziwa ngokwezifiso ukuze ahlangabezane nezidingo zephrojekthi ethile. Ngaphezu kwalokho, amapayipi angenamikhawulo e-WIRBITED ARCC ajwayele ukwenziwa ngensimbi esezingeni eliphakeme, okwenza ukuthi azwele futhi aqinisekise impilo ende yenkonzo.
I-API 5L Line Pipe:
I-API 5L Line Pipeipayipi elisetshenziswayo elisetshenziswa kabanzi elihlangene namazinga aseMelika petroleum Institute (API). Lawa mapayipi aklanyelwe ukuhambisa uketshezi, njengamafutha negesi yemvelo, amabanga amade. I-API 5L Line Pipe yaziwa ngamandla ayo aphezulu, ukuqina kanye nokumelana nemibandela yezemvelo eyeqile.
Inqubo yokukhiqiza ye-API 5L Line Pipe ifaka izindlela eziqinile zokulawula ikhwalithi yokuqinisekisa ukuthembeka kwayo. Lawa mapayipi enziwe ngensimbi yekhabhoni futhi abe nezakhiwo ezinhle kakhulu zemishini. Ukubambelela ngokuqinile kumazinga we-API kuqinisekisa ukuthi la mapayipi angamelana nezingcindezi eziphakeme kanye nezinguquko zokushisa, ezenza zilungele izicelo ezibucayi embonini kawoyela negesi.
Izinzuzo ezihlanganisiwe:
Lapho kufakwa ipayipi le-arc cwile elisezingeni eliphansi kanye ne-API 5L Line Pipe, zinikezela ngobuqotho obungenakuqhathaniswa nokwethembeka. Ama-seams avuthayo wepayipi le-SSAW ahlanganiswe namandla nokuqina kwe-API 5L Line Pipe Dala uhlelo oluqinile lokusekelwa kwesakhiwo.
Ngaphezu kwezinzuzo zabo ezifanele, ukuhambisana kwepayipi elifakwe emzimbeni eliphakathi nendawo kanye ne-API 5L Line Pipe kwandisa ukusebenza kwamaphrojekthi wepayipi. Ukuguquguquka okuhlukahlukene kwe-SSAW Pipe kuvumela ukuxhumana okulula nge-API 5L Line Pipe, uqinisekise ukuhamba komthungo koketshezi ngaphakathi kwenethiwekhi yepayipi.
Ekuphetheni:
Amapayipi we-Hollol Pepes abaluleke kakhulu lapho wakhe ingqalasizinda eqinile. Ukusetshenziswa okuhlangene kwe-SSAW Pipe ne-API 5L Line Pipe kunikeza isixazululo esinamandla esinikeza amandla, ukuqina kanye nokwethenjwa kwamaphrojekthi ahlukahlukene. Noma ngabe isekela izisekelo zezakhiwo ezinde noma ukuthutha uketshezi olubucayi ngamabanga amade, la mapayipi adlala indima ebalulekile ekuqinisekiseni ubusuku obude nokuqina kwengqalasizinda yethu. Ngokufaka amandla amandla wepayipi elifakwe emgodini we-arc ofakwe e-api kanye nokwethenjwa kwepayipi le-API 5l, onjiniyela bangakha isisekelo esiqinile sosuku olungcono.
