Tuubooyinka gariiradda tayada leh
Waxaanu nahay khabiir ku takhasusay tuubooyinka gariiradda, isagoo leh khibrad iyo farsamooyin si aan ula kulanno adeegga leexinta tubbada, dhammaan tuubooyinka waxaa lagu tijaabiyaa 100% cadaadiska ku habboon, tuubooyinka gudaha iyo dibeddaba waa nadiif oo isku day inaad xirto,
- foorarsi sax ah
- Qalloocis jilicsan
- Dusha qallafsanaanta Ra <0.5 μm
- Dulqaadka caadiga ah: ASTM A269, ama D4/T4
Ka dib marka la nadiifiyo, toosinta tuubooyinka birta aan fiicnayn waa jilicsanaan, tuubooyinka waa la foorarsan karaa, la samayn karaa, laga sameeyay jihooyin iyo xaglo kala duwan, nidaamka kulaylka, tuubooyinka caadiga ah waa U laabashada iyo tuubooyinka gariiradda, sidoo kale warshadaha cuntada, waxay yihiin heerka cuntada birta aan lahayn.
Caadiga ah Cabbirrada Gariiradda Tuubbada Aan-Aabaha lahayn
Tuubbada birta ah ee aan fiicnayn waxaa loogu talagalay qaab gariiradda, dhexroor yar yar guud ahaan, dhererka tuubada ugu badnaan waxay noqon kartaa 1000 mitir, iyada oo aan lahayn wax bir ah oo wadajir ah, waxaa jira cabbirro kala duwan oo kala duwan oo ah tuubooyinka birta ah ee duubista, dhexroorka dibadda ee caadiga ah ayaa hoos lagu bixiyaa, iyo dhumucda derbiga laga bilaabo 0.0275 inch - 0.083 inch, dhererka ugu badan wuxuu gaaraa 1000 mitir.
Gariiradda Tuubbada Birta Aanay Ahayn ee Iftiirta Annealing
Waxaan bixinaa tuubo welded oo aan fiicneyn oo qaab duuban, waaberiga qabow waa in la sameeyaa, haddii loo baahdo, nidaam sax ah ayaa la heli karaa, si loo helo dusha siman, tuubooyinka waxaa lagu farsameyn karaa dhammaystir dhalaalaya oo dhalaalaya.,
Faa'iidooyinka Tubooyinka Isku Dufan
Gariiradda tuubooyinka birta ah ee birta ah waxay leeyihiin iska caabin heerkul sare oo heer sare ah iyo iska caabin daxalka, marka la barbar dhigo tuubada cooper, dhumucdiisuna waxay hoos u dhigi kartaa 30% - 60%, ma aha mid dhuuban oo aad u dhumuc weyn, ma aha miridhku iyo fayodhowr, yaraynta wakhtiga dayactirka, badbaadinta kharashka , fududahay in la rakibo oo la beddelo.
