"Iyada oo ku saleysan suuqa gudaha iyo ballaarinta ganacsiga dibadda" waa istaraatiijiyadeenna hagaajinta ee tayada Wanaagsan ee 25crmov birta birta ah ee aan fiicnaynQabow duuban/qabow la sawiray oo saxan tuubo bir ah oo aan xuduud lahayn35CrMo 42CrMo, Raadinta mustaqbalka, dariiq dheer oo loo maro, si joogto ah ugu dadaala sidii ay u noqon lahaayeen dhammaan shaqaalaha xamaasad buuxda leh, boqol jeer kalsoonida oo gelinaysa shirkadeena dhistay deegaan qurux badan, alaabo horumarsan, urur casri ah oo heerka koowaad ah oo tayo sare leh iyo si adag u shaqee!
"Ku salaysan suuqa gudaha iyo ballaarinta ganacsiga dibadda" waa istaraatijiyad horumarinta ourQabow duuban/qabow la sawiray oo saxan tuubo bir ah oo aan xuduud lahayn, Warshadayadu waxa ay ku fadhidaa dhul dhan 12,000 oo mitir oo laba jibbaaran, waxana ka hawl gala 200 oo qof, kuwaas oo ay ka mid yihiin 5 maamule farsamo.Waxaan ku takhasusnay wax soo saarka. Waxaan leenahay khibrad qani ah xagga dhoofinta.Ku soo dhawoow inaad nala soo xidhiidho, su'aashaadana waxa lagaga jawaabi doonaa sida ugu dhakhsaha badan.
Saxnaanta Birta aan Xumaan lahaynTuubooyinka farsamada iyo qaab dhismeedka iftiinka.Tani waxay keenaysaa sifooyin badan oo isku mid ah oo dhan tuubada marka loo eego tuubooyinka caadiga ah.Iyadoo tuubooyinka makaanikada loo soo saari karo qeexitaannada caadiga ah marka la codsado, guryaha "caadiga ah" waxay caadi ahaan soo saaraan xoogga wax-soo-saarka ee cabbirka saxda ah iyo dhumucda derbiga.Qaar ka mid ah codsiyada aadka loo sameeyay, xoogga wax-soo-saarka ayaa laga yaabaa inaan xitaa la cayimin oo tuubada farsamada ayaa la soo saaray "ku habboon isticmaalka".Tuubooyinka makaanikada waxaa ku jira codsiyo qaab dhismeed iyo mid aan dhisneyn oo ballaaran.
Haihui Steel, waxaanu ku dabaqnaa khibradeena birta iyo wax soo saarka si aanu u soo saarno alaabada tuubbooyinka farsamaysan ee wax qabadkoodu sarreeyo si loo daboolo baahiyahaaga.
Tan waxaa ka mid ah kaarboon, alloys iyo xitaa darajooyinka birta caadiga ah;la jeexjeexay, la caadiyeeyay oo la xanaaqay;culayska la yareeyey oo aan diiqada lahayn;demisay oo xanaaqsan.

Habaynta Gaarka ah
Alaabooyinka tubbada ee khaaska ah ee isku xidhka tuubooyinka waxay ku bilaabmaan birta tayada ugu sareysa.Darajada, falanqaynta kiimikada iyo xaaladda dusha si taxadar leh ayaa loo tixgaliyaa, iyo hababka wax soo saarka ayaa loo habeeyey si loo gaaro tubbada ugu fiican ee isticmaalka dhamaadka.
Habayntu waxay ka samaysan tahay tuubo wareegsan iyadoo sawir qabow laga sameeyay.Tuubada waxaa lagu sawiraa mander qaabaysan ama iyada oo loo sii marayo dhinta qaabaysan, ama labadaba.Dulqaadyada la wanaajiyay, dhammaynta iyo natiijadii sifooyinka farsamada.
