Qabow duuban Tuubbada birta ah ee la jeexjeexay saxnaanta C20, C45, S235, S355, 1020, 1045, 4130, 4140
Sharaxaad Gaaban:
Tuubooyinka birta makaanikada ah waxaa loo adeegsadaa qaybo la farsameeyay ama la sameeyay oo loogu talagalay warshadaha, baabuurta, mishiinada beeraha, diyaaradaha, gaadiidka, maaraynta alaabta iyo qalabka guriga.Waxa loo soo saaray si sax ah dhexroorka ka baxsan iyo cabbirka dhumucda gidaarka.
Qalab si wanaagsan loo maamulo, kooxda iibka xirfadleyda ah, iyo adeegyo iib-ka-iib ah oo wanaagsan;Waxaan sidoo kale nahay qoys weyn oo midaysan, qof kastaa wuxuu ku dheggan yahay qiimaha shirkadda "midaynta, dadaalka, dulqaadka" ee Cold Rolled Drawn Steel Tube Clan Precision C20, C45, S235, S355, 1020, 1045, 4130, 4140, Waxaan bixin doonaa inta badan tayada sare ee waxtarka leh, oo laga yaabo inay tahay qaybta ugu xoogga badan, macaamiisha cusub iyo kuwa hore ee leh dhammaan adeegyada cagaaran ee ugu fiican.
Qalab si wanaagsan loo maamulo, kooxda iibka xirfadleyda ah, iyo adeegyo iib-ka-iib ah oo wanaagsan;Waxaan sidoo kale nahay qoys weyn oo midaysan, qof kastaa ku dheji shirkadda qiimaha "midaynta, dadaalka, dulqaadka" waayo, Hadafkayagu waa "inay bixiso alaabta tallaabada ugu horreysa iyo xalalka iyo adeegga ugu fiican ee macaamiishayada, sidaas darteed waxaan hubinnay inaad u baahan tahay inaad haysato faa'iido margin ah iyada oo nala kaashanaysa."Haddii aad xiisaynayso mid ka mid ah alaabtayada ama aad jeceshahay inaad ka hadasho dalabka gaarka ah, hubi inaad xor u tahay inaad nala soo xidhiidho.Waxa aanu rajaynaynaa in aanu mustaqbalka dhaw la samayno xidhiidh ganacsi oo guulaysta macaamiisha cusub ee aduunka.
Tuubooyinka makaanikada waxaa loo adeegsadaa codsiyada qaab dhismeedka farsamada iyo iftiinka.
Tuubooyinka makaanikada waxaa loo soo saaray si ay u buuxiyaan shuruudaha isticmaalka dhamaadka gaarka ah, qeexitaannada, dulqaadka iyo sifooyinka kiimikada.
Tuubooyinka farsamada iyo qaab dhismeedka iftiinka.Tani waxay u oggolaaneysaa isku mid ahaanshaha guryaha oo dhan tuubada oo dhan marka la barbar dhigo tuubooyinka ama tuubooyinka caadiga ah.Tuubooyinka makaanikada waxaa loo soo saari karaa qeexitaannada caadiga ah marka loo baahdo, laakiin badanaa waxaa loo soo saaraa waxqabadka "caadiga ah", iyada oo diiradda koowaad la saarayo xoogga dhalidda ee cabbirka saxda ah iyo dhumucda derbiga.Qaar ka mid ah codsiyada aadka loo sameeyay, xoogga wax-soo-saarka ayaa laga yaabaa inaan xitaa la cayimin, iyo soo saarista tuubooyinka farsamada "ku habboon isticmaalka".Tuubooyinka makaanikada waxaa ku jira codsiyo qaab dhismeed iyo mid aan dhisneyn oo ballaaran.
Waxaan u adeegsanaa khibradeena birta iyo wax soo saarka si aan u soo saarno alaabada tuubada farsamada ee aan fiicnayn si aan u daboolno baahiyahaaga.
Tan waxaa ka mid ah kaarboon, alloys iyo xitaa darajooyinka birta caadiga ah;la jeexjeexay, la caadiyeeyay oo la xanaaqay;culayska la yareeyey oo aan diiqada lahayn;oo damiyey oo xanaaqsan.
Dhuumaha birta ee mashiinada iyo baabuurta, oo loo isticmaalo samaynta iyo habaynta tubbada jirridda baabuurta iyo tubooyinka dabada, qalabka saxda ah, qalabka iyo qalabka.
Qaabka baabuurka iyo tuubada dabada
Soo-saarka iyo habaynta qalabka saxda ah, qalabka iyo qalabka.
Shuruudaha keenista: GBK, BKS, BK, BKW, NBK.
Hubi oo tijaabi:Halabuurka kiimikada, sifooyinka farsamada, muuqaalka iyo tijaabinta cabbirka, tijaabinta aan burburin, baaritaanka cabbirka walxaha.
Daaweynta dusha sare:Saliid galinta, faashash, toogashada.

Alaabooyinka tubbada ee khaaska ah ee isku xidhka tuubooyinka waxay ku bilaabmaan birta tayada ugu sareysa.Darajada, falanqaynta kiimikada iyo xaaladda dusha si taxadar leh ayaa loo tixgaliyaa, iyo hababka wax soo saarka ayaa loo habeeyey si loo gaaro tubbada ugu fiican ee isticmaalka dhamaadka.
Habayntu waxay ka samaysan tahay tuubo wareegsan iyadoo sawir qabow laga sameeyay.Tuubada waxaa lagu sawiraa mander qaabaysan ama iyada oo loo sii marayo dhinta qaabaysan, ama labadaba.Dulqaadyada la wanaajiyay, dhammaynta iyo natiijadii sifooyinka farsamada.
Tuubooyinka aan xidhnayn iyo alxanka ee codsiyada farsamada iyo injineernimada guud.Tubooyinka dhismaha iyo ujeedooyinka qaabdhismeedka sida dhismayaasha madaniga ah, aasaaska, iwm.
