Waxaan hadda leennahay koox karti leh oo wax qabad leh si ay u siiyaan adeegyadeena adeegyo tayo wanaagsan leh.Waxaan inta badan raacnaa mabda'a macmiilka-oriented, faahfaahinta diiradda saaraya Qiimaha Gaarka ah ee SSAW/Sawl API 5L Spiral Welded Carbon Steel Pipe Gaaska Dabiiciga ah iyo Dhuumaha Saliidda, Intaa waxaa dheer, waxaan si sax ah u hagi lahaa macaamiisha farsamooyinka codsiga si ay u qaataan xalalkayaga iyo habka loo doorto alaabta ku habboon.
Waxaan hadda leennahay koox karti leh oo wax qabad leh si ay u siiyaan adeegyadeena adeegyo tayo wanaagsan leh.Waxaan inta badan raacnaa mabda'a ku jihaysan macmiilka, tafaasiisha ku wajahanShiinaha LSAW/SSAW Dhuumaha Birta iyo Dhuumaha alxanka, Hadafkayagu waa in aan u gudbino qiimaha joogtada ah ee macaamiishayada iyo macaamiishooda.Ballanqaadkani waxa uu saameeyaa wax kasta oo aanu samayno, isaga oo nagu riixaya in aanu si joogto ah u horumarino oo aanu u wanaajino xalalkayaga iyo hababka aan ku buuxino baahiyahaaga.
Dhuumaha lagu dalbado qeexitaankan waxaa loo isticmaalaa adeega cadaadiska sare ee jawiga iyo heerkulka hoose. Inta badan waxaa loo isticmaalaa gudbinta saliidda iyo gaaska dabiiciga ah.
ASTM A671 LSAW(JCOE) Dhuumaha Birta Kaarboon waa inay ahaataa laba-alxanka, alxanka si buuxda loo sameeyo si waafaqsan habraacyada iyo alxankayaasha ama hawlwadeenada alxanka oo u qalma si waafaqsan Shuban Biyoodka ASME iyo Xeerka Vessel Code, Qaybta IX.
Dhammaan fasallada aan ka ahayn 10, 11, 12 iyo 13 waa in lagu daaweeyaa kulaylka foornada lagu kontoroolo ±15℃ oo lagu qalabeeyaa hydrometer duubista si diiwannada kululaynta loo helo.
