Dulmar
"Daacadnimo, Hal-abuurnimo, Adag, iyo Hufnaan" waxay noqon kartaa fikradda joogtada ah ee ururkeenna, muddadaas dheer ee is-dhaafsiga labada dhinac, Waqtigan xaadirka ah, magaca shirkaddu wuxuu leeyahay birta kaarboonka iyo Cr Mo Alloy Steel alaabta wuxuuna helay rikoor sare iyo saamiyo waaweyn suuqa gudaha iyo dibadaba.
Mid ka mid ah isticmaalka tubooyinkayaga waa shaqooyinka dabka, sida gaadiidka biyaha ee shaqada dabka, ilaalinta siliga korontada ee nidaamka dab-damiska iyo wixii la mid ah.
Fadlan ogow, tuubooyinka birta ductile, tuubooyinka naxaasta, tuubooyinka daawaha, tuubooyinka isku dhafan, tuubooyinka birta kaarboon, iwm. ayaa inta badan loo isticmaalaa tuubooyinka dab-damiska. Shuruudaha cabbirku way ka duwan yihiin tuubooyinka ujeedada guud waxayna leeyihiin shuruudo gaar ah oo iyaga u gaar ah. Tuubooyinka dab-damiska guud ahaan waxay u baahan yihiin in lagu rinjiyeeyo rinji cas ama goobabada cas. Si loo kala saaro dhuumaha kale.
Hawlgalka dhabta ah, qaybaha kala duwan ee nidaamka ilaalinta dabku waxay leeyihiin shuruudo kala duwan oo loogu talagalay noocyada iyo alaabta tuubooyinka, sida: tuubooyinka dusha sare ee tuubooyinka dabka gudaha, marka nidaamka cadaadiska shaqada uu ka yar yahay ama la mid yahay 1.20MPa, tuubooyinka birta ah ee kulul ee kulul. waa la isticmaali karaa; Marka cadaadiska shaqadu ka weyn yahay 1.20MPa, tuubo bir ah oo dhumuc kulul leh ama tuubo bir ah oo kulul waa in la isticmaalaa; marka nidaamka cadaadiska shaqada uu ka weyn yahay 1.60MPa, tuubooyinka birta ah ee galvanized kulul waa in la isticmaalaa.
