Tuubada alxanka leh ee Arc Spiral ee quusta ee khadadka gaaska
Tuubooyinka alxanka leh ayaa si joogto ah loo soo saaraa waxayna aragti ahaan soo saari karaan tubooyinka birta ah ee aan dhammaadka lahayn.Habkan wax soo saarka ayaa yaraynaya khasaaraha jarista madaxa iyo dabada halka ay kordhinayso isticmaalka birta 6% ilaa 8%.Tani waxay u horseedi doontaa kaydinta kharashka iyo waxtarka macaamiisheena.
Ourtuubooyinka alxanka leh ee wareegsanwaxay bixiyaan dabacsanaan hawleed heer sare ah marka loo eego tuubooyinka tolida toosan ee dhaqanka.Way fududahay in la beddelo oo la isku hagaajiyo noocyada, taas oo ka dhigaysa kuwo ku habboon mashaariicda u baahan la-qabsi iyo habeyn.Intaa waxaa dheer, awoodaha makaanaynta iyo iswada ee tuubooyinkeena alxanka leh waxay u oggolaanayaan in si fudud looga hirgeliyo goobo warshadeed oo kala duwan.

Waayokhadadka gaaska, tuubada alxanka spiral waxay bixisaa xal waara oo la isku halayn karo.Nidaamkeeda wax soo saar ee joogtada ah waxay hubisaa tayada iyo xoogga joogtada ah, taas oo muhiim u ah gaadiidka gaaska dabiiciga ah.Dabacsanaanta iyo la qabsiga tuubada alxanka ee spiral welded ayaa sidoo kale ka dhigaysa mid ku habboondhuunta alxankacodsiyada.Haddi ay tahay mashruuc warshadeed, ganacsi ama deegaan, alaabadayadu waxay ku siinayaan waxqabadka iyo kalsoonida aad u baahan tahay.
Tuubooyinkayada alxanka leh ee wareegsan waxaa loo soo saaray heerarka tayada ugu sarreeya si ay u buuxiyaan shuruudaha warshadaha.Waxaan isticmaalnaa tignoolajiyada casriga ah iyo injineernimada saxda ah si aan u soo saarno alaab ka sarreysa filashooyinka.Tuubo kasta si adag ayaa loo tijaabiyey oo loo baadhay si loo hubiyo inay buuxisay shuruudaha lagama maarmaanka u ah codsiyada dhuumaha gaaska.
Marka laga soo tago faa'iidooyinka farsamada, tuubooyinkayada alxanka leh ee spiral waxaa loogu talagalay iyadoo maskaxda lagu hayo baahida macaamiisha.Laga soo bilaabo rakibaadda ilaa dayactirka, tuubooyinkayada alxanka leh ee wareegsan ayaa loogu talagalay ugu habboonaanta.
Waxaa naga go'an inaan siino macaamiisheena alaabada iyo xalalka ugu fiican si loo daboolo baahidooda.Soo bandhigida tubooyinka alxankayaga ee wareegsan waxay ka tarjumaysaa u heellanaantayada hal-abuurka iyo heerka sare ee warshadaha.Waxaan aaminsanahay in alaabtayadu ay dabooli doonaan oo ay dhaafi doonaan baahida codsiyada khadadka gaaska, waxaanan rajeyneynaa inaan daboolno baahiyaha macaamiisheena iyada oo la kaashanayo tayada ugu sareysa iyo taageerada.
