Tuubo bir ah oo dhalaalaya oo dhammaystiran ayaa ah walxo tuubo bir ah oo sax ah ka dib marka la dhammeeyo sawir ama rogid qabow. Sababtoo ah darbiyada gudaha iyo dibadda ee tuubooyinka dhalaalaya ee sax ah ma laha lakab oksaydh ah, ma jiraan wax daadanaya cadaadis sare, saxnaan sare, dhammaystir sare, isbeddel la'aan inta lagu jiro foorarsiga qabow, flaring, simitaan iyo dildilaac la'aan, iwm., waxaa inta badan loo isticmaalaa in lagu soo saaro alaabada qaybaha pneumatic ama hydraulic, sida dhululubada ama dhululubada saliidda, kuwaas oo noqon kara tuubooyin aan kala go 'lahayn ama tuubooyin alxan. Halabuurka kiimikada ee tuubada dhalaalaya ee sax ah waxaa ka mid ah kaarboon C, silicon Si, manganese Mn, sulfur S, fosfooraska P, iyo chromium Cr.
Astaamaha ugu muhiimsan ee dhammaystirka tuubada dhalaalaya:
Darbiyada gudaha iyo dibadda ee tuubada birta ah waxay leeyihiin saxnaan sare iyo dhammaystir sare. Ka dib daaweynta kulaylka, tuubada birta ah ma laha lakab oksaydh ah, derbiga gudahana wuxuu leeyahay nadiifin sare. Tuubada birta ah waxay leedahay cadaadis sare, foorarsiga qabowga ma beddelo, iyo fidsanaanta iyo simitaanka ma dillaacdo. Tuubada birta ah ee la duubay ee ay bixiso Tianjin Century Zoomlion waxaa loo isticmaali karaa qaabab kala duwan oo isku dhafan iyo farsamayn farsamo. Midabka tuubada birta ah: caddaan oo leh iftiin, oo leh dhalaal bir ah oo sarreeya.
Heerka caadiga ah, agabka iyo heerka gaarsiinta ee dhammaystirka-tuubooyin dhalaalaya oo la duubay
Heerarka ugu muhiimsan: GB/T3639, DIN2391-94/C, DIN2445, EN10305, DIN1630, DIN1629, ASTMA106, ASTMA179, JISG3445
Agabka ugu muhiimsan: 10 #, 20 #, 35,45,40Cr, 25Mn.37Mn5, St35 (E235), St37.4, St45 (E255), St52 (E355)
Xaaladda gaarsiinta ugu muhiimsan: NBK (+N), GBK (+A), BK (+C), BKW (+LC), BKS (+SR)
Codsigadhammayn-tuubooyin dhalaalaya oo la duubay
Gawaarida, qalabka mashiinnada iyo mashiinno kale oo leh shuruudo sare oo loogu talagalay saxnaanta iyo simanaanta tuubooyinka birta ah. Hadda isticmaalayaasha tuubooyinka birta ah ee la duubay ee la duubay ma aha oo kaliya kuwa leh shuruudo sare oo loogu talagalay saxnaanta iyo dhammaystirka. Sababtoo ah saxnaanta tuubooyinka dhalaalaya ee la duubay ee la duubay ayaa sarreeya dulqaadkuna wuxuu ku hayn karaa 2-8 fiilooyin, dad badan oo isticmaala farsamaynta farsamada ayaa si tartiib tartiib ah u beddelaya tuubooyinka birta ah ee aan kala go 'lahayn ama birta wareegsan una beddelaya tuubooyin dhalaalaya oo la duubay si loo badbaadiyo khasaaraha shaqada, agabka iyo waqtiga.
