| a. Indlela ye-Deaxotion ichongwe ngolu hlobo lulandelayo: I-FF: Intsimbi egcinwe ngokupheleleyo i-nitrogen ebophelelayo kwizixa ezaneleyo zokubopha initrogen (umz. I-0,020% ye-al). b. Elona xabiso liphezulu le-nitrogen alisebenzi ukuba ukubekwa kwekhemikhali kubonisa i-0,020% ye-al / n i-2: 1, okanye ukuba izinto ezaneleyo ze-N-Bing zikhona. Izinto ezibophelelayo ziya kurekhodwa kuxwebhu lovavanyo. | ||||||||
Uvavanyo lwe-hydrostatic
Ubude bombhobho buya kuvavanywa ngumenzi kwingcinezelo ye-hydrostatic eya kuthi ivelise udonga lombhobho woxinzelelo olungaphantsi kwe-60% yamandla egumbi elichaziweyo kubushushu begumbi. Ingcinezelo iya kugqitywa ngale quation ilandelayo:
P = 2st / d
Umahluko ovumelekileyo kwimilinganiselo kunye nobungakanani
Ubude bombhobho buya kuba bunzima ngokwahlukeneyo kwaye ubunzima bayo bungayihlukanga ngaphezu kwe-10% ngaphezulu okanye i-5.5% phantsi kobunzima bayo, babalwa besebenzisa ubude beyunithi nganye
Ububanzi bangaphandle abuyiwa ngaphezulu kwe- ± 1% ukusuka kwibala elichaziweyo ngaphandle kwe-diameter
Ubunzima bodonga nangayiphi na inqaku aliyi kuba ngaphezulu kwe-12,5% phantsi kobunzima obuchaziweyo
1. QAPHELA i-S235 JR Spiral Pipe:
I-S235 jer spiral pipe yentsimbingumbhobho we-welflow welfmed osetyenziswe ngokubanzi kwiinkqubo zemibhobho. Zenziwe ngentsimbi esemgangathweni ephezulu ngokuhambelana nemigangatho yehlabathi, ukuqinisekisa ukuqina okuphezulu kunye namandla.
