Dulmar
Waxaan sameyn doonaa dadaal shaqsiyeed si aan unoqno mid gaar ah oo ku haboon, waxaanan dardargelin doonaa talaabooyinkayaga ku aadan joogitaanka darajada shirkadaha aduunka ugu sareeya iyo kuwa tignoolajiyada sare ee A53 Gr. B Dhuumaha Birta Kaarboonka ee Aan Laxaadka Lahayn/Alxankarin, Waxaanu kugu soo dhawaynaynaa inaad soo booqato warshadeena oo aanu rajaynayno samaynta xidhiidh saaxiibtinimo oo saaxiibtinimo leh macaamiisha gudaha iyo dibadaba mustaqbalka dhow. Dhammaan alaabadayada iyo xalalkeena waxay u hoggaansamaan heerarka tayada caalamiga ah waxaana si weyn looga mahadcelinayaa suuqyada kala duwan ee adduunka. Haddii aad xiisaynayso mid ka mid ah alaabtayada ama aad jeclaan lahayd inaad ka hadasho dalabka gaarka ah, xusuusnow inaad xor u tahay inaad nala soo xidhiidho. Waxaan sugeynay inaan xiriir ganacsi oo guul leh la samayno macaamiisha cusub mustaqbalka dhow.
ASTM A53 waxay qeexaysaa shuruudaha tubada birta galvanized-ka ah iyo kuwa aan xidhnayn/alxanka lahayn ee isticmaalka guud. Birta ku taxan heerka caadiga ah waa in lagu farsameeyaa foornada hawada furan, ogsijiinta alkaline ama foornada korontada, waana in ay lahaataa shuruudahan kiimikaad ee soo socda: kaarboon, manganese, fosfooraska, baaruud, copper, nikkel, chromium, molybdenum iyo vanadium. Dhuumaha waa in ay ahaataa mid aan kala go 'lahayn ama alxan. Tijaabooyinka xajinta, foorarsiga iyo fidinta waa in la sameeyaa si loo hubiyo inay tahay inay la kulanto sifooyinka farsamada caadiga ah. Tijaabada cadaadiska Hydrostatic waa in la sameeyaa, oo aan wax ka daadan alxanka ama jirka tuubada. Tijaabooyin koronto oo aan burbursanayn waa in la sameeyaa si loo hubiyo in tirada guud ee dhuumaha ay tahay inay buuxiso heerka. Haddii loo arko inay lagama maarmaan tahay in la hubiyo in dhuumuhu buuxiyo shuruudaha la cayimay, iibsaduhu wuxuu xaq u leeyahay inuu sameeyo baaritaan kasta iyo baaritaanno lagu qeexay qeexitaankan.
ASTM A 53 waxay ku haboon tahay nidaamka tuubooyinka cadaadiska, tuubooyinka tuubooyinka iyo tuubooyinka ujeedada guud ee heerkulka 350 darajo. Waxaa ka mid ah, darajada birta ee Gr.B ayaa ah tan ugu badan ee la isticmaalo, oo leh quwad xajin ah ≥ 415 (MPa) iyo dhalid xoog ≥ 240 (MPa).
Codsiga
Waxaa inta badan loo isticmaalaa qaybaha xoogga iyo cadaadiska, iyo ujeedada guud uumiga, biyaha, gaaska iyo tuubooyinka hawada.
