Nooca 316 iyo 347 kulaylka lagu daweeyay tuubooyinka birta ah, kuwan tuubooyinka birta ah waxaa badanaa loo isticmaalaa codsiyada leh heerkul sare iyo bay'ad daxalaysa. 316 steel waa bir bir ah oo leh iska caabin daxalka wanaagsan, halka 347 birta aan daxalka ahayn ay leedahay iska caabin kulayl sare leh.
Tuubooyinkan waxaa inta badan loo isticmaalaa warshadaha sida kiimikooyinka, sifaynta, farsamaynta saliidda iyo gaasta, iyo sidoo kale kulaylka sare ee sariflayaasha, foornooyinka, iyo qalabka kale ee heerkulka sare. Marka la dooranayo tuubooyinkan, arrimaha ay ka midka yihiin heerkulka hawlgalka, shuruudaha cadaadiska, iyo bay'adaha daxalka ayaa loo baahan yahay in la tixgeliyo.
Birta aan lahayn Ferritic. Waxa ku jira 12% ilaa 30% chromium. Iska caabbinta daxalka, adkaanta iyo alxanka waxay kordhisaa kororka maadada chromium, iyo iska caabbinta daxalka chloride-ka ayaa ka fiican noocyada kale ee birta aan-ka-baxa lahayn.
Ogow:
1.Saamaynta bilaashka ah, 100% hubinta tayada iibka ka dib, Taageer hab kasta oo lacag bixin ah;
2.Dhammaan qeexitaannada kale ee tuubooyinka birta kaarboonka wareega ayaa la heli karaa iyadoo loo eegayo baahidaada (OEM & ODM)! Qiimaha warshadda waxaad ka heli doontaa ROYAL GROUP.

Horumarka warshaduhu si degdeg ah ayuu isu beddelaa, tuubooyinka birta-tuba waxay sidoo kale raacaan horumarinta warshadaha si ay u daboolaan baahiyaha horumarineed ee warshadaha kala duwan. Kuwa soo socda waa codsiyada ballaaran eetuubooyinka wareegsan ee birta ahwarshadaha kala duwan:
Bixinta biyaha iyo tuubooyinka qulqulka, nidaamyada waraabka
Biyo-siinta iyo injineernimada dhuumaha qulqulka waxaa loogu talagalay gaadiidka iyo warshadaha qaybinta. Biyaha la cabbo iyo ururinta. Gaadiidka iyo daadinta biyaha wasakhda ah ee warshadaha. Biyaha bulaacada gudaha iyo tuubooyinka biyaha roobka (channel) injineernimada nidaamka.
Maalgelinta injineernimada ayaa xisaabisa inta badan wadarta maalgashiga injineernimada. Nidaamyada waraabinta dabaysha waa qayb muhiim ah oo ka mid ah isticmaalka biyaha beeraha. Tilmaamaha jireed iyo kiimikaad ee tuubooyinka biyaha ee birta ah waxay buuxinayaan shuruudaha daaweynta biyaha beeraha ee casriga ah.
Hababka isku xirkani waxay leeyihiin cabbiro codsi oo kala duwan iyadoo loo eegayo mabaadi'dooda kala duwan, laakiin intooda badan way fududahay in la rakibo, xooggan oo la isku halleyn karo. Giraanta shaabadda ama shaabadda loo isticmaalo isku xirka inta badan waxay ka samaysan tahay caag silikoon, caag nitrile ah iyo EPDM caag ah oo buuxiya heerarka qaranka, kaas oo ka nafisaya isticmaalayaasha walwalka.
1. Baakadaha xaashida caaga ah
Inta lagu jiro qaadista tubooyinka birta ah, balaastigga ayaa inta badan loo isticmaalaa in lagu xidho tuubooyinka. Habkan baakaduhu wuxuu faa'iido u leeyahay inuu ka ilaaliyo dusha sare ee tuubada birta ah ee ka soo baxda xirashada, xoqidda iyo wasakheynta, sidoo kale waxay door ka ciyaaraan ilaalinta qoyaanka, boodhka iyo ka hortagga daxalka.
2. Baakadaha cajaladda
Baakadaha cajaladdu waa hab la awoodi karo, fudud oo fudud oo lagu xidhi karo tuubooyinka birta ah, sida caadiga ah iyadoo la isticmaalayo cajalad cad ama cad. Isticmaalka baakadaha cajaladuhu ma ilaalin karaan oo keliya dusha sare ee dhuumaha, laakiin sidoo kale waxay xoojinayaan xoogga dhuumaha waxayna yareynayaan suurtagalnimada barokaca ama qalloocinta dhuumaha inta lagu jiro gaadiidka.
3. Baakad alwaax ah
Gaadiidka iyo kaydinta tubooyinka birta ee waaweyn, baakada alwaaxdu waa hab wax ku ool ah. Tuubooyinka birta ah ayaa lagu dhejiyaa sariiraha birta ah ee birta ah, kuwaas oo bixin kara difaac aad u wanaagsan oo ka hortagaya in tuubooyinka isku dhacaan, foorarsadaan, qalloociyaan, iwm inta lagu jiro gaadiidka.
4. Baakadaha kartoonnada
Tuubooyinka birta yar yar, baakadaha kartoonku waa hab caadi ah. Faa'iidada baakadaha kartoonku waa inay fududdahay oo ay fududahay in la raro. Marka lagu daro ilaalinta dusha sare ee tuubada, waxay sidoo kale noqon kartaa mid ku habboon kaydinta iyo maareynta.
5. Baakadaha weelka
Dhoofinta dhuumaha birta ah ee baaxadda weyn, baakadaha weelka waa hab caadi ah. Baakadaha weelku waxay hubin karaan in dhuumaha si badbaado leh loo qaado oo aan shil ku dhicin badda, lagana fogaado leexinta, isku dhaca, iwm inta lagu jiro gaadiidka.
