Iinkcukacha zeMveliso

Iithegi zeMveliso

Kwicandelo lokwakha kunye nelokuvelisa, ukukhethwa kwezinto ze-welding kunye neendlela zidlala indima ebalulekileyo ekugqityweni ngempumelelo kwayo nayiphi na iprojekthi.Enye yezinto ezinjalo eziye zaduma kwiminyaka yakutshanje ngumbhobho wesakhiwo owenziwe ngokubanda.Le mveliso ivelisa izinto ezintsha ibonelela ngeengenelo ezininzi ngaphezulu kwemibhobho yemveli engenamthungo okanye edityanisiweyo, ngakumbi imibhobho yomthungo ejiyileyo.

Kuyabanda yakhiwe ngesakhiwo esidityanisiweyoumbhobho wenziwa ngenkqubo yokubumba ebandayo, ebandakanya ukugoba kunye nokwenza iikhoyili zentsimbi kwimilo efunekayo.Isiphumo singumbhobho oqinileyo kwaye oqinileyo, kodwa ulula kwaye kulula ukuwusebenzisa.Ukongezelela, inkqubo yokubumba ebandayo iqinisekisa ukuba umbhobho ugcina ukunyaniseka kwesakhiwo kunye nokuchaneka kwe-dimensional, okwenza kube yinto efanelekileyo kwizicelo ze-welding.

Uvavanyo lweHydrostatic

Ubude bombhobho ngamnye buya kuvavanywa ngumenzi kuxinzelelo lwe-hydrostatic oluya kuvelisa eludongeni lombhobho uxinzelelo olungekho ngaphantsi kwama-60% obona buncinci buchaziweyo bamandla esivuno kwindawo yobushushu begumbi.Uxinzelelo luya kumiselwa ngolu nxaki lulandelayo:
P=2St/D

Ukwahluka okuvumelekileyo kubunzima kunye nemilinganiselo

Ubude bombhobho ngamnye buya kulinganiswa ngokwahlukileyo kwaye ubunzima bawo abuyi kwahluka ngaphezu kwe-10% ngaphezulu okanye i-5.5% phantsi kobunzima bethiyori, kubalwe kusetyenziswa ubude bayo kunye nobunzima bayo ngobude beyunithi.
Idayamitha yangaphandle ayisayi kwahluka ngaphezu kwe ±1% kwidayamitha echaziweyo yangaphandle echaziweyo.
Ubunzima bodonga nakweyiphi na indawo abuyi kuba ngaphezu kwe-12.5% phantsi kobukhulu bodonga oluchaziweyo.

Ubude

Ubude obubodwa obungakhethiyo: 16 ukuya ku-25ft (4.88 ukuya ku-7.62m)
Ubude obuphindwe kabini obungenamkhethe: ngaphezulu kwe-25ft ukuya kwi-35ft (7.62 ukuya kwi-10.67m)
Ubude obufanayo: ukwahluka okuvumelekileyo ±1in

Iyaphela

Iimfumba zemibhobho ziya kubonelelwa ngeziphelo ezicacileyo, kwaye i-burrs ekupheleni iya kususwa.
Xa isiphelo sombhobho esichazwe ukuba sibe yi-bevel siphela, i-angle iya kuba ngama-30 ukuya kuma-35 degrees

Enye yeenzuzo eziphambili ze-welded welded structureumbhobho wokuweldakukukwazi ukumelana namaqondo obushushu aphezulu kunye noxinzelelo.Ngokungafaniyo nemibhobho yemveli, enokuthi ichaphazeleke kwi-corrosion kunye nezinye iindlela zokuthotywa, imibhobho eyenziwe ngokubanda yenziwe ngobunjineli ukuze imelane nobunzima be-welding kunye nezinye iinkqubo zoshishino.Oku kubenza balungele ukusetyenziswa kwizicelo ezahlukeneyo ukusuka kulwakhiwo lwezakhiwo ukuya kwiiprojekthi zeziseko zophuhliso.

Enye inzuzo yombhobho wesakhiwo odibeneyo owenziwe ngokubanda yindleko yayo.Inkqubo yokubumba ebandayo inokuvelisa imibhobho kwiintlobo ezahlukeneyo zobukhulu kunye neemilo, ukunciphisa imfuno yokuphosa ezibizayo kunye neenkqubo zomatshini.Oku kwenza ukuba imveliso ifikeleleke ngakumbi kwaye ithembekile njengombhobho ongenamthungo okanye odibeneyo.Ukongezelela, ubume obulula bombhobho owenziwe ngokubanda kwenza ukuthutha kunye nofakelo kube lula kwaye kube neendleko eziphantsi, ngakumbi ukwandisa isibheno sayo.

Iityhubhu ze-Spiral seam zixhamla ngokukodwa kwinkqubo yokubumba ebandayo.Amandla endalo kunye nokuguquguquka kweetyhubhu eziyilwe ngokubanda zizenza zilungele ukudala amalungu ajiyileyo ahlala ixesha elide kwaye anobungqina bokuvuza.Oku kubenza babe lolona khetho lubalaseleyo kwiinkqubo ezifana neenkqubo zokuhambisa amanzi angaphantsi komhlaba, iintambo zamanzi kunye neenkqubo zokunkcenkceshela kwezolimo.Ukongezelela, ubuso obugudileyo bemibhobho eyenziwe ngokubanda bunciphisa umngcipheko wokungqubuzana kunye nokugqoka, ukwandisa ubomi bombhobho kunye nokunciphisa imfuno yokugcina nokulungiswa.

Lilonke, umbhobho wesakhiwo odityanisiweyo obandayo unika inani leenzuzo eziyenza ibe lolona khetho lubalaseleyo kwizicelo zokuwelda, ngakumbi umbhobho we-spiral seam.Amandla abo, ukuqina kunye nokuphumelela kweendleko kubenza ukuba bakhethe okukhangayo kuluhlu olubanzi lwamashishini, ukusuka kulwakhiwo ukuya kwimveliso.Njengoko imfuno yomgangatho ophezulu, izinto ezithembekileyo ziqhubeka zikhula, umbhobho wesakhiwo owenziwe ngokubanda odibeneyo uya kuba yinto ethandwa kakhulu kwizicelo ze-welding.
