GB8163 Line Steel Dhuumaha birta aan xuduud lahayn

Sharaxaad Gaaban:

GB 8163 Dhuumaha birta ah ee aan xujada lahayn waxaa loo isticmaalaa gudbinta batroolka, gaaska dabiiciga ah iyo dareerayaasha kale ee caadiga ah.Dhuumaha birta ah waxa ay leedahay qayb godan, waxaana si weyn loogu isticmaalaa sida tuubada gudbinta dareeraha, sida saliidda, gaaska dabiiciga ah, gaasta, biyaha iyo qaar ka mid ah walxaha adag.

Hordhac Product

Marka la barbar dhigo birta adag sida birta wareegsan, tuubada birta ayaa miisaankeedu fudud yahay marka foorarsiga iyo xoogga toggu ay isku mid yihiin.Waa bir iskutallaabta-dhaqaale ah oo si ballaaran loo isticmaalo si loo soo saaro qaybo dhismeed iyo qaybo makaanik ah, sida tuubada daloolista saliidda, shafka gudbinta baabuurta, jir baaskiilka iyo birta birta ah ee loo isticmaalo dhismaha.Soo saarista qaybaha giraanta u samaysan ee leh tubooyinka birta waxay wanaajin kartaa heerka isticmaalka alaabta, fududaynayso habka wax soo saarka, waxaanay kaydin kartaa agabka iyo saacadaha habaynta, sida giraangiraha duubista iyo gacmaha jaakada.Waqtigan xaadirka ah, tuubooyinka birta ayaa si weyn loogu isticmaalay wax soo saarka.Dhuumaha birta sidoo kale waa shay lagama maarmaan u ah dhammaan noocyada hubka caadiga ah.Foostada iyo fuustada qoryaha ayaa ka samaysan tuubo bir ah.Tuubooyinka birta ah waxaa loo qaybin karaa tuubooyinka wareegsan iyo tuubooyinka qaabka gaarka ah iyadoo loo eegayo meelo iyo qaabab kala duwan oo iskutallaab ah.Maadaama aagga wareeggu uu yahay kan ugu weyn ee hoos yimaada xaaladda wareegga siman, dareere badan ayaa lagu qaadi karaa tuubooyinka wareegyada.Intaa waxaa dheer, marka qaybta giraanta lagu soo rogo cadaadis gudaha ama dibadda ah, xooggu waa labis badan.Sidaa darteed, inta badan tuubooyinka birta ayaa ah tuubooyinka wareegsan.

Habka Tignoolajiyada

Wareegid kulul (oo soo saarta tuubo bir ah oo aan fiicneyn): tuubo wareeg ah oo bannaan → kuleyl → daloolin → saddex rogaal celis ah, duubid joogto ah ama extrusion → tuubooyinka tuubada → cabbirka (ama yaraynta) → qaboojinta → tuubo bannaan → toosin → tijaabo hydrostatic → calaamadeyn → bakhaar.

Qabow jeexan (duuban) tuubo bir ah oo aan fiicneyn: tuubada wareega → kululaynta → daloolin → ciwaanka → dajinta ogaanshaha) → calaamadaynta → kaydinta.
