ERW Welding Round Steel Amapayipi

I-ERW Welding Round Steel Pipes Isithombe Esifakiwe

Incazelo emfushane:

Amapayipi ayindilinga ashiselwe i-ERW aziwa nangokuthi amapayipi ashiselwe ukumelana.Lolu hlobo lwepayipi yensimbi ehlanganisiwe lusetshenziswa kabanzi emikhakheni ehlukahlukene efana nobunjiniyela, uthango, isikafula, amapayipi omugqa, njll. Amapayipi ensimbi ashiselwe i-ERW atholakala ngezimfanelo ezihlukahlukene, ubukhulu bodonga kanye nobubanzi bepayipi eliphelile.

Isingeniso Somkhiqizo

Amashubhu ashiselwe ukumelana nogesi (ERW) akhiqizwa ngokubanda okwenza umucu wensimbi oyisicaba ube yishubhu eliyindilinga futhi awudlulise ochungechungeni lwamaroli okwakhiwa ukuze kutholwe ukushisela okude.Imiphetho emibili ibe isishisiswe kanyekanye nge-high-frequency current futhi iyaminyana ukuze yakhe ibhondi.Ayikho insimbi yokugcwalisa edingekayo ekushiseleleni ama-longitudinal ERW.

Azikho izinsimbi ezihlanganisiwe ezisetshenziswa ngesikhathi sokukhiqiza.Lokhu kusho ukuthi ipayipi liqine ngokwedlulele futhi lihlala isikhathi eside.

I-weld seam ayikwazi ukubonakala noma ukuzwa.Lona umehluko omkhulu uma ubheka inqubo yokushisela i-arc engaphansi kwamanzi ephindwe kabili, eyenza ubuhlalu obucacile obubunjiwe obungase budingeke buqedwe.

Ngokuthuthuka kwamaza kagesi anemvamisa ephezulu yokushisela, inqubo ilula kakhulu futhi iphephile.

Amapayipi ensimbi e-ERW akhiqizwa yi-low-frequency noma high-frequency resistance "resistance".Amapayipi ayindilinga ashiselwe ngamapuleti ensimbi anamashisela e-longitudinal.Isetshenziselwa ukuthutha uwoyela, igesi yemvelo nezinye izinto eziwuketshezi oluwuketshezi, futhi ingahlangabezana nezidingo ezihlukahlukene zokucindezela okuphezulu nokuphansi.Njengamanje, inesikhundla esibalulekile emkhakheni wamapayipi ezokuthutha emhlabeni.

Ngesikhathi sokushisela ipayipi le-ERW, ukushisa kukhiqizwa lapho okwamanje kugeleza endaweni yokuxhumana yendawo yokushisela.Ishisisa imiphetho emibili yensimbi kuze kube yilapho unqenqema olulodwa lungakha isibopho.Ngesikhathi esifanayo, ngaphansi kwesenzo sokucindezela okuhlangene, imiphetho ye-tube engenalutho iyancibilika futhi ihlanganise ndawonye.

Ngokuvamile ipayipi le-ERW eliphezulu OD lingu-24" (609mm), ipayipi lezilinganiso ezinkulu lizokhiqizwa nge-SAW.

Isibonisi somkhiqizo

Hlobo luni lwamapayipi (izindinganiso) ezingenziwa ezinqubweni ze-ERW?

Kunamapayipi amaningi angakhiqizwa inqubo ye-ERW.Lapha ngezansi sibhala izindinganiso ezivame kakhulu kumapayipi.

Ipayipi lensimbi ye-Carbon ku-ERW.

I-ASTM A53 IBanga A no-B (futhi Ifakwe Amathafa).

Ipayipi lenqwaba ye-ASTM A252.

Ishubhu yesakhiwo se-ASTM A500.

Ipayipi le-ASTM A134 ne-ASTM A135.

I-EN 10219 S275, ipayipi le-S355.

API ERW Line Pipe

I-API 5L B ukuya ku-X70 PSL1 (PSL2 izoba kunqubo ye-HFW)

I-API 5CT J55/K55, i-N80 casing kanye neshubhu nokunye.

Ukusetshenziswa kwepayipi lensimbi ye-ERW kanye nokusetshenziswa:
Ipayipi lensimbi le-ERW elisetshenziselwa ukuthutha igesi nezinto eziwuketshezi ezifana nowoyela negesi, lingahlangabezana nemfuneko yomfutho ophansi nophezulu.Eminyakeni yamuva, ngokuthuthukiswa kobuchwepheshe be-ERW, ipayipi lensimbi le-ERW liya ngokuya lisetshenziswa emasimini kawoyela negesi, imboni yezimoto nokunye.

Izinzuzo zepayipi le-ERW:
Ukusebenza kahle okuphezulu, izindleko eziphansi, ukonga impahla, i-automation elula.
