Marka laga hadlayo kharashyada gardarrada ah, waxaan aaminsanahay inaad meel walba ka raadin doonto wax kasta oo naga adkaan kara. Waxaan si hubaal ah u sheegi karnaa in qiimahaas aadka u wanaagsan awgeed, aan ahayn kan ugu hooseeya ee soo saaraha tuubooyinka birta ah ee kaarboonka ah ee birta ah ee Shiinaha ee cusub ee la keenay ASTM A53 ERW oo la welded bir wareegsan oo PPE ah oo leh tuubo madow oo khafiif ah oo loogu talagalay dhismaha, waxaan had iyo jeer u aragnaa tignoolajiyada iyo macaamiisha inay yihiin kuwa ugu sarreeya. Waxaan had iyo jeer si adag u shaqeynaa si aan u abuurno qiimo weyn macaamiisheenna waxaanan macaamiisheenna u siinaa alaab iyo adeegyo wanaagsan.
Dhanka eedeymaha gardarrada ah, waxaan aaminsanahay inaad meel walba ka raadin doontaan wax kasta oo naga adkaan kara. Waxaan si hubaal ah u sheegi karnaa in qiimahaas aadka u wanaagsan awgeed aanu nahay kuwa ugu hooseeya ee aan u baahanahay.Tuubada Birta Kaarboon Shiinaha iyo Qalabka Dhismaha, Alaabta ugu muhiimsan ee shirkaddayadu si weyn ayaa looga isticmaalaa adduunka oo dhan; 80% alaabtayada iyo xalalkayaga waxaa loo dhoofiyaa Mareykanka, Japan, Yurub iyo suuqyo kale. Dhammaan waxyaabaha si daacad ah ayaa loo soo dhaweeyaa martida si ay u soo booqdaan warshaddayada.
Tuubada lagu dalbaday qeexitaankan waxaa loo isticmaalaa qaab-dhismeedka.
