Iinkcukacha zemveliso

Iimpawu zeMveliso

Kumacandelo okwakha kunye nemveliso, ukhetho lwezixhobo zeWediding kunye neendlela zidlala indima ebalulekileyo ekugqityweni ngempumelelo nakweyiphi na iprojekthi. Esona sixhobo sithandwayo kwiminyaka yakutshanje iyayilwa imibhobho ye-Weldied. Le mveliso intshabalalo inika izibonelelo ezininzi kuninzi okanye imibhobho yemveli engenamthungo okanye ye-wellded, ngakumbi imibhobho ye-spiral seam.

Kubanda Yenza i-Weldid ye-WeldiedUmbhobho wenziwa ngenkqubo yokwenziwa ebandayo, ebandakanya ukugoba kunye nokwakha iikhoyiki zentsimbi kwimo efunekayo. Isiphumo ngumbhobho obomeleleyo kwaye unxunguphele, kodwa ulula kwaye usebenzise lula. Ukongeza, inkqubo yokuqubana ebandayo iqinisekisa ukuba umbhobho ogcina ingqibelelo yakhe kunye nokuchaneka kwayo, kwenza ilungele ukusetyenziswa kwe-welding.

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 abuyi kudliwa ngaphezulu kwe-10% ngaphezulu okanye i-5.5% phantsi komzimba wayo, ukubalwa kusetyenziswa ubude bayo.
Ububanzi bangaphandle abuyi kwahluka ngaphezu kwe- ± 1% ukusuka kwibala elichaziweyo langaphandle.
Ubunzima bodonga nangayiphi na inqaku aliyi kuba ngaphezulu kwe-12,5% phantsi kobunzima obuchaziweyo.

Ubude

Ubude obungakhethwanga okanye i-16 ukuya kwi-25ft (4.88 ukuya kwi-7.62m)
Ubude obuPhindwe kabini: Ngaphezulu kwe-35ft ukuya kwi-35ft (7.62 ukuya kwi-10.67m)
Ubude be-iyunifomu: ukwahluka okwaneleyo ± 1in

Iphela

Imfumba yepayiwe iya kugcinwa ngobutyebi ecacileyo, kwaye iifayili eziphelweni ziya kususwa
Xa umbhobho wokuphela echazwe ukuba i-Bevel iphela, i-engile iya kuba ngama-30 ukuya kwi-35 degree

Esona sibonelelo siphambili sokubanda kwe-welded ye-weldedumbhobho we-weldingkukukwazi kwabo ukumelana nobushushu obuphakamileyo kunye noxinzelelo. Ngokungafaniyo nemibhobho yemveli, echaphazelekayo ukusulelwa kunye nezinye iindlela zokupheliswa, imibhobho esekwe ebandayo ixhaswe kukungabinamphetho kunye nezinye iinkqubo zemveliso. Oku kubangela ukuba balungele ukusetyenziswa kwezicelo ezahlukeneyo ezivela kulwakhiwo lokwakha kwiiprojekthi zeziseko zophuhliso.

Elinye i-inzuzo yombhobho obandayo obandayo yindleko zawo zokusebenza. Inkqubo yokwakha ebandayo inokuvelisa imibhobho kubungakanani beentlobo kunye neemilo, ukunciphisa isidingo seenkqubo zokuphelisa kakhulu kunye neenkqubo zomatshini. Oku kwenza ukuba imveliso ifikeleleke ngakumbi kwaye ithembeke njengombhobho okanye umbhobho we-welding. Ukongeza, ubume obukhanyisiweyo bombhobho obandayo obandayo buyahamba kunye nokufakwa lula kwaye kusebenza kakubi kakhulu kwaye kuyanda isibheno sayo.

I-Spiral Seam Tubes ixhamla kwinkqubo yokwakha ebandayo. Amandla endalo kunye nokuguquguquka kwe-tuus ezibandayo zenze ukuba balungele ukudala amalungu aqinileyo kwaye avule. Oku kubangela ukuba babe lukhetho oluhle kwizicelo ezinje ngeenkqubo zokushishina komhlaba, imigca yamanzi kunye neenkqubo zokunkcenkceshela kwezolimo. Ukongeza, indawo egudileyo yemibhobho ebandayo inciphisa umngcipheko wokuxabana nokunxiba, ukwandisa ubomi bombhobho kunye nokunciphisa isidingo solondolozo kunye nokulungiswa.

Ngokubanzi, kubanda kwemibhobho ye-Weldied ye-Weldied ibonelela ngeenzuzo ezininzi ezenza ukuba zibe lukhetho oluhle lwezicelo ze-welding, ngakumbi umbhobho we-Spiral Spiral. Amandla abo, ukuqina kunye nokusebenza ngendleko kwenza ukuba khetha ukhetho olubanzi lwamashishini ahlukeneyo, ukusuka ekwakhiweni kwemveliso. Njengoko imfuno yezixhobo ezisemgangathweni ezisemgangathweni, ezinokuthenjwa ziyakhula, umbhobho obandayo we-Weldied Weldied uya kuba lukhetho oluyanda kwizicelo ze-welding.
