I. Dulmar Guud ee Badeecada
GB/T9948-2013Tuubo bir ah oo aan kala go 'lahayn waa tuubo bir ah oo tayo sare leh oo si gaar ah loogu isticmaalo habka dildilaaca batroolka, waxaana si weyn loogu isticmaalaa qalabka muhiimka ah sida tuubooyinka foornada, beddelayaasha kulaylka iyo tuubooyinka cadaadiska ee warshadaha saliidda. Heerkani wuxuu si adag u nidaamiyaa agabka, habka wax soo saarka iyo shuruudaha waxqabadka ee tuubooyinka birta si loo hubiyo hawlgalkooda xasilloon ee jawiyada daxalka sare, heerkulka sare iyo cadaadiska sare.
2. Agabka iyo waxqabadka
1. Agabka ugu muhiimsan
GB/T9948-2013Tuubooyinka birta ah ee aan kala go 'lahayn waxaa laga sameeyay noocyo kala duwan oo agab bir ah oo tayo sare leh, oo ay ku jiraan:
Birta dhismaha ee kaarboon:20G, 20MnG, 25MnG
Birta dhismaha ee daawaha:15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB
Bir aan miridh lahayn iyo bir u adkaysta kulaylka: 1Cr18Ni9, 1Cr18Ni11Nb
2. Waxqabadka asaasiga ah
Iska caabin heer-kul sare: Ku habboon hababka heerkulka sare sida dildilaaca batroolka (ilaa 600°C ama ka badan).
Iska caabinta cadaadiska sare: Alaabada xoogga badan waxay hubinayaan hawlgal ammaan ah oo dhuumaha ah oo ka jira jawi cadaadis sare leh.
Iska caabbinta daxalka: Qaybaha gaarka ah ee dahaarka leh waxay si wax ku ool ah uga hortagaan warbaahinta daxalka leh sida hydrogen sulfide iyo carbon dioxide.
Kalsooni sare: Xakamaynta tayada adag waxay hubineysaa in sifooyinka farsamada iyo halabuurka kiimikada ee tuubooyinka birta ah ay buuxiyaan heerka GB/T9948.
3. Habka wax soo saarka
Tuubooyinka birta ah ee GB/T9948-2013 waxaa lagu sameeyaa duubis kulul iyo sawir qabow (rogid):
Habka kulul ee duubista: tuubo wareegsan oo billet ah → kuleylinta → daloolinta → rogid → cabbiraadda → qaboojinta → toosinta → kormeerka tayada → kaydinta.
Habka sawir-qaadista qabow (rogidda): daloolinta → qajaarka → sawir-qaadista qabowga → daaweynta kulaylka → toosinta → ogaanshaha cilladaha → calaamadaynta → kaydinta.
Labada habba waxay hubiyaan saxnaan cabbir sare leh, dusha siman iyo sifooyin farsamo oo heer sare ah oo tuubooyinka birta ah.
4. Meelaha codsiga
Tuubooyinka dillaaca batroolka GB/T9948 si ballaaran ayaa loo isticmaalaa:
Warshadaha kiimikada batroolka: cutubka dildilaaca, fal-galka hydrogenation, qalabka dib-u-habaynta catalytic
Warshadaha sifeynta saliidda: tuubooyinka foornada heerkulka sare leh, beddelayaasha kulaylka, dhuumaha cadaadiska sare leh
Gaadiidka gaaska dabiiciga ah: dhuumaha gudbinta gaaska ee u adkaysta daxalka, oo cadaadis sare leh
Soo saarista kuleyliyaha: kuleyliyaha saldhigga korontada, nidaamyada dhuumaha kuleyliyaha warshadaha
5. Rajooyinka suuqa
Iyadoo ay si degdeg ah u korayso warshadaha kiimikada ee gudaha iyo kororka baahida suuqa caalamiga ah, mugga iibka ee tuubooyinka birta ah ee aan kala go 'lahayn ee GB/T9948 ayaa sii kordhaya. Iska caabbin heer sare ah oo heer sare ah iyo iska caabbinta daxalka ayaa ka dhigaya walxaha tuubooyinka ee ugu doorbida badan meelaha lagu sameeyo dildilaaca iyo sifaynta batroolka.
6. Taxaddarrada iibsashada iyo isticmaalka
Xulashada walxaha adag: Xullo walxaha GB/T9948 ee ku habboon (sida 12CrMoG, 15CrMoG, iwm.) iyadoo loo eegayo xaaladaha shaqada (heerkulka, cadaadiska, daxalka).
Shahaadada Tayada: Hubi in tuubada birta ahi ay buuxiso heerka GB/T9948-2013 oo ay bixiso warbixin kormeer oo dhinac saddexaad ah.
Rakibaadda iyo dayactirka: Ka fogow waxyeelada farsamada inta lagu jiro rarista iyo rakibidda, oo si joogto ah u hubi daxalka dhuumaha iyo xaaladaha cadaadiska.
Tuubada dillaaca batroolka ee GB/T9948-2013 waxay noqotay doorasho ku habboon batroolka kiimikada, sifeynta, gaaska dabiiciga ah iyo warshadaha kale sababtoo ah faa'iidooyinkeeda iska caabbinta heerkulka sare, iska caabbinta cadaadiska sare iyo iska caabbinta daxalka. Xulashada agabka ku habboon (sida 12CrMoG, 15CrMoG, iwm.) iyo si adag u raacitaanka heerarka waxay hubin kartaa hawlgalka muddada dheer ee badbaadada iyo xasilloonida dhuumaha.
