    Tuubbada alxanka leh ee dhulka hoostiisa ku duugan waa qayb muhiim ah oo ka mid ah injineernimada biyaha, warshadaha batroolka, warshadaha kiimikada, warshadaha tamarta korontada, waraabka beeraha, iyo dhismaha magaalooyinka. Wax-soo-saarka iyo isku-kalsoonaanta ay leedahay ayaa ka dhigay mid ka mid ah labaatanka wax soo saarka ee dalkeena laga sameeyay, taasoo muujinaysa muhiimadda iyo saamaynta ay ku leeyihiin warshadaha kala duwan.

    SSAW tuubo bir ahwaxaa loo sameeyay daabulida cabitaannada waxayna ku habboon tahay sahayda biyaha iyo nidaamka bullaacadaha. Dhismaheeda adag ayaa ka dhigaya mid ku habboon hubinta wareejinta dareeraha hufan oo la isku halayn karo. Intaa waxaa dheer, waxay sidoo kale ku habboon tahay gaadiidka gaasta sida gaaska dhuxusha, uumiga, iyo gaaska dareeraha ah. Awoodeeda adag ee sare iyo iska caabbinta daxalka waxay hubisaa bixinta gaaska badbaadada iyo waxtarka leh waxayna buuxisaa shuruudaha adag ee nidaamyada gaaska gaaska.

    Mid ka mid ah codsiyada ugu muhiimsan ee tuubooyinka birta ee alxanka leh waakhadka gaaska dhulka hoostiisa. Iyada oo ay tayadeedu sarreyso iyo waxqabadkeeda, waa doorashada koowaad ee lagu dhisayo isku-xidhka gaadiidka gaaska dabiiciga ah oo la isku halayn karo oo ammaan ah.

    Dhuumaha Biyaha Dhulka Hoostiisa

    X65 SSAW dhuunta xariiqdawaxaa laga dhisay qalab heersare ah oo hubinaya xoog sare iyo adkaysi. Tani waxay ka dhigeysaa mid ku habboon codsiyada u baahan cadaadis sare iyo iska caabin arrimaha deegaanka. Ku habboonaanta rakibaadda dhulka hoostiisa waxay sii iftiiminaysaa naqshadeeda adag iyo awoodda ay u leedahay inay u adkeysato xaaladaha adag, taasoo ka dhigaysa xalka doorashada mashaariicda dhuumaha gaaska dhulka hoostiisa.

    Sida badeeco la aamini karo oo la xaqiijiyay, tuubooyinkayada birta ah ee qallafsan ee qallafsan ayaa si weyn looga qaataa dhammaan warshadaha iyo mashaariicda kaabayaasha sababtoo ah waxqabadkooda sare, adkeysigooda iyo isku halaynta. Dhismaheeda tayada sare leh ayaa ka dhigaya doorashada koowaad ee nidaamka gaadiidka dareeraha iyo gaaska, gaar ahaan khadka gaaska dhulka hoostiisa ah halkaas oo badbaadada iyo waxtarka ay muhiim u yihiin.

    Marka la soo koobo, dhuumaha birta ee lingaxan ee xuubka dhuudhuuban waa badeeco aad u wanaagsan oo loogu talagalay in lagu daboolo baahiyaha kala duwan ee nidaamka gudbinta dareeraha iyo gaaska. Isku-kalsoonaanta iyo isku-kalsoonaanta awgeed, waxay noqotay qayb weyn oo ka mid ah warshadaha kala duwan iyo mashaariicda kaabayaasha, gaar ahaan khadka gaaska ee dhulka hoostiisa. Tayada gaarka ah iyo waxqabadkeeda ayaa ka dhigaya hanti qiimo leh oo lagu hubinayo shabakad gaadiid gaas oo hufan oo badbaado leh. Ku kalsoonow isku halaynta iyo waxqabadka tuubooyinka birta ee dhuudhuuban ee arc welded ee dhammaan baahiyahaaga gaadiidka gaaska.
