I-API 5L Steel Line Pipe Plate

I-API 5L Steel Pipe Plate Isithombe Esifakiwe

Incazelo emfushane:

I-Pipeline steel iwuhlobo lwepuleti lensimbi elisetshenziselwa amapayipi, ikakhulukazi asetshenziswa ekwenzeni amapayipi amapayipi kawoyela negesi yemvelo, kanye namalahle nezinto zokwakha ezidakanayo.Insimbi ayidingi nje amandla aphezulu okucindezela, kodwa futhi idinga ukuqina kokushisa okuphansi okuphezulu kanye nokushisela okuhle kakhulu.

Isingeniso Somkhiqizo

Insimbi yamapayipi yesimanje iyinsimbi enekhabhoni ephansi noma i-ultra-low-carbon microalloyed, okuwumkhiqizo onokuqukethwe okuphezulu kobuchwepheshe kanye nenani eliphakeme elengeziwe.Iningi lempumelelo yobuchwepheshe obusha emkhakheni we-metallurgical eminyakeni engama-20 edlule isetshenziswe ekukhiqizeni insimbi yamapayipi.Umkhuba wokuthuthuka wobunjiniyela bamapayipi ububanzi bepayipi elikhulu, ukuthuthwa kwegesi ecebile enengcindezi ephezulu, ukupholisa okuphezulu, indawo esetshenziswa kakhulu ukugqwala, kanye nogqinsi lwamapayipi angaphansi kolwandle.Ngakho-ke, insimbi yesimanje yamapayipi kufanele ibe namandla aphezulu, umphumela we-Bauschinger ophansi, ukuqina okuphezulu nokumelana nokuqina, okuqukethwe kwekhabhoni ye-weld ephansi kanye nokushisela okuhle, nokumelana nokugqwala kwe-HIC ne-H2S.

I-pipeline steel plate isetshenziselwa ukwakha amapayipi kalayini ashiselwe, ngoba amapayipi kalayini angenamthungo enziwe ngebha eyindilinga, hhayi amapuleti ensimbi.Ipuleti eliwugqinsi elimaphakathi ngokuvamile lisetshenziselwa ukukhiqiza ipayipi elishiselwe odongeni eliqondile lomthungo, futhi insimbi yekhoyili isetshenziselwa ukukhiqiza ipayipi likagesi elingamelana neshiselwe (ERW) kanye nepayipi eli-spirally submerged arc welded(SSAW).Namuhla, ayanda amaklayenti adinga ipuleti lensimbi yepayipi ukuze akhiqize amapayipi kalayini ngenxa yokuthi amapuleti ensimbi angasetshenziswa ukwenza amapayipi amakhulu amakhulu, ngaphezu kwalokho, intengo yamapayipi ashiselwe ngokuvamile iphansi kunaleyo yamapayipi angenamthungo.

Ipuleti lensimbi yepayipi liyinto ebalulekile ekukhiqizeni ipayipi likalayini le-ERW, ipayipi lomugqa we-LSAW, ipayipi lomugqa we-SSAW, elisetshenziswa ekwakhiweni komugqa wamapayipi ekuthuthweni kukawoyela, igesi kanye namanzi, angasetshenziswa ekukhiqizeni ukwakhiwa kokudluliselwa koketshezi olucindezelayo.

Amazinga okushisa aphansi kakhulu e-arctic, izingcindezi ezinkulu ekujuleni kolwandle, imidiya ye-asidi: ngisho nezimo ezinolaka kakhulu azinawo umthelela omubi kumapuleti ethu omugqa.Ama-linepipe plate ayakwazi ukusebenza ekujuleni okungafika kumamitha ayi-2,800 ngaphansi kolwandle.

Siphinde futhi sinikeze ipuleti lensimbi lesakhiwo elihlanganiswe ne-roll-bonded offshore elinesimboli esimelana nokugqwala ngezidingo eziphezulu kakhulu zokusetshenziswa kwegesi emuncu.Njengochwepheshe kubuchwepheshe besimanje be-thermo mechanical rolling obunokupholisa okusheshayo, siphakathi kwabaholi bomkhakha womhlaba.
