Iingenelo zeMibhobho yesakhiwo eWelded Cold Form Welded Structure

Iingenelo zeMibhobho yesakhiwo eWelded eyenziwe ngokubanda eWelded Umfanekiso ocacileyo

Inkcazo emfutshane:

Le nkcazelo igubungela amanqanaba amahlanu ombhobho wentsimbi ye-helical-seam edityaniswe ngombane-fusion (arc). Lo mbhobho wenzelwe ukuhambisa ulwelo, igesi okanye umphunga.

Ngemigca eli-13 yemveliso yombhobho wentsimbi ejikelezayo, iCangzhou Spiral Steel pipes group Co., Ltd. inako ukuvelisa imibhobho yentsimbi enomthungo ojikelezayo enobubanzi obungaphandle ukusuka kwi-219mm ukuya kwi-3500mm kunye nobukhulu bodonga obufikelela kwi-25.4mm.

Iinkcukacha zeMveliso

Iithegi zeMveliso

Kwicandelo lokwakha nelokuvelisa, ukukhethwa kwezinto zokutywina kunye neendlela kudlala indima ebalulekileyo ekugqityweni ngempumelelo kwayo nayiphi na iprojekthi. Enye yezinto ezinjalo eziye zathandwa kwiminyaka yakutshanje yipayipi yokwakha edityanisiweyo eyenziwe ngokubandayo. Le mveliso intsha inika iingenelo ezininzi kuneepayipi zemveli ezingenamthungo okanye ezidityanisiweyo, ingakumbi iipayipi zomthungo ezijikelezayo.

Ukubanda isakhiwo esidityanisiweyo esenziwe nge-weldedUmbhobho wenziwa ngenkqubo yokwenza ubanda, equka ukugoba nokwenza iikhoyili zentsimbi zibe yimo efunekayo. Isiphumo ngumbhobho oqinileyo nohlala ixesha elide, kodwa okhaphukhaphu kwaye kulula ukuwusebenzisa. Ukongeza, inkqubo yokwenza ubanda iqinisekisa ukuba umbhobho ugcina ulungelelwano lwesakhiwo sawo kunye nokuchaneka kobukhulu, okwenza ukuba ube ngofanelekileyo kwiindlela zokufaka iintsimbi.

Uvavanyo lwe-Hydrostatic

Ubude bombhobho ngamnye buya kuvavanywa ngumvelisi kuxinzelelo lwe-hydrostatic oluya kuvelisa eludongeni lombhobho uxinzelelo olungaphantsi kwama-60% wamandla aphantsi okuvelisa kubushushu begumbi. Uxinzelelo luya kugqitywa yile equation ilandelayo:
P=2St/D

Utshintsho Oluvumelekileyo Kubunzima Nobukhulu

Ubude bombhobho ngamnye buya kulinganiswa ngokwahlukeneyo kwaye ubunzima bawo abuyi kwahluka ngaphezu kwe-10% ngaphezulu okanye i-5.5% phantsi kobunzima bawo obuqikelelwayo, obubalwe kusetyenziswa ubude bawo kunye nobunzima bawo ngobude beyunithi nganye.
Ububanzi bangaphandle abuyi kwahluka ngaphezu kwe-±1% ukusuka kububanzi obuqhelekileyo bangaphandle.
Ubukhulu bodonga nangaliphi na ixesha abuyi kuba ngaphezulu kwe-12.5% phantsi kobukhulu bodonga obuchaziweyo.

Ubude

Ubude obungacwangciswanga obunye: 16 ukuya kwi-25ft (4.88 ukuya kwi-7.62m)
Ubude obuphindwe kabini obungacwangciswanga: ngaphezulu kwe-25ft ukuya kwi-35ft (7.62 ukuya kwi-10.67m)
Ubude obufanayo: umahluko ovumelekileyo ±1in

Iphela

Iipayipu mazifakelwe iziphelo ezingenanto, kwaye iziphelo ezisemaphethelweni mazisuswe.
Xa isiphelo sepayipi esichazwe njengesiphelo se-bevel, i-engile mayibe ngama-30 ukuya kuma-35 degrees

Enye yezona nzuzo ziphambili zesakhiwo esidityanisiweyo esenziwe ngobandayoumbhobho wokuweldayikhono layo lokumelana namaqondo obushushu aphezulu kunye noxinzelelo. Ngokungafaniyo nemibhobho yendabuko, enokugqwala kunye nezinye iindlela zokonakala, imibhobho eyenziwe ngokubanda yenzelwe ukumelana nobunzima bokudityaniswa kwentsimbi kunye nezinye iinkqubo zoshishino. Oku kuyenza ilungele ukusetyenziswa kwiintlobo ngeentlobo zezicelo ukusuka kulwakhiwo lwezakhiwo ukuya kwiiprojekthi zeziseko zophuhliso.

Enye inzuzo yombhobho wolwakhiwo odibeneyo owenziwe ngokubandayo kukusebenza kakuhle kweendleko. Inkqubo yokwenza okubandayo inokuvelisa imibhobho ngobukhulu obahlukeneyo kunye neemilo, inciphisa isidingo seenkqubo zokubumba kunye noomatshini ezibizayo. Oku kwenza imveliso ibe nexabiso eliphantsi kwaye ithembeke njengembhobho engenamthungo okanye edibeneyo. Ukongeza, uhlobo olulula lombhobho owenziwe ngokubandayo lwenza ukuthuthwa kunye nokufakwa kube lula kwaye kube nexabiso eliphantsi, nto leyo eyandisa ukuthandwa kwayo.

Iityhubhu zomthungo ezijikelezayo zixhamla kakhulu kwinkqubo yokwenza ubanda. Amandla angaphakathi kunye nokuguquguquka kweetyhubhu ezenziwe ngokubanda kuzenza zibe zilungele ukudala iijoyinti ezijikelezayo ezihlala ixesha elide nezingenako ukuvuza. Oku kuzenza zibe lukhetho oluhle kakhulu kwizicelo ezifana neenkqubo zokuhambisa amanzi phantsi komhlaba, imigca yamanzi kunye neenkqubo zokunkcenkceshela kwezolimo. Ukongeza, umphezulu ogudileyo weepayipi ezenziwe ngokubanda unciphisa umngcipheko wokungqubana nokuguguleka, wandise ubomi beepayipi kwaye unciphise isidingo sokugcinwa nokulungiswa.

Ngokubanzi, umbhobho wolwakhiwo odityanisiweyo owenziwe ngokubandayo unika inani leenzuzo ezenza ukuba ube lukhetho oluhle kakhulu lokusetyenziswa kwe-welding, ingakumbi umbhobho womthungo ojikelezayo. Amandla awo, ukuqina kwawo kunye nokusebenza kakuhle kweendleko kuwenza ube lukhetho olunomtsalane kumashishini amaninzi, ukusuka kulwakhiwo ukuya kumveliso. Njengoko imfuno yezinto ezisemgangathweni ophezulu nezithembekileyo iqhubeka ikhula, umbhobho wolwakhiwo odityanisiweyo owenziwe ngokubandayo uza kuba lukhetho oluthandwa kakhulu lokusetyenziswa kwe-welding.
