I. Dulmarka alaabta
GB/T9948-2013Dhuumaha birta ah ee aan kala go'a 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, kulaylka beddelayaasha iyo tuubooyinka cadaadiska ee warshadaha saliidda. Heerkani wuxuu si adag u xakameynayaa walxaha, habka wax soo saarka iyo shuruudaha waxqabadka ee tuubooyinka birta si loo hubiyo in hawlgalkooda xasilloon ee daxalka sare, heerkulka sare iyo jawiga cadaadiska sare leh.
2. Qalabka iyo waxqabadka
1. Qalabka ugu muhiimsan
GB/T9948-2013Tuubooyinka birta ah ee aan toobin waxay ka samaysan yihiin waxyaabo kala duwan oo tayo sare leh, oo ay ku jiraan:
Bir dhismeed kaarboon:20G, 20MnG, 25MnG
Bir dhismeed Alloy:15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB
Bir aan-ahma lahayn iyo birta kulaylka u adkaysata: 1Cr18Ni9, 1Cr18Ni11Nb
2. Waxqabadka asaasiga ah
Iska caabin heerkul sare ah: Waxay ku habboon tahay hababka heerkulka sare sida dildilaaca batroolka (ilaa 600 ° C ama ka badan).
Cadaadiska cadaadiska sarreeya: Qalabka xoogga badan ayaa hubiya hawlgalka badbaadada ee dhuumaha hoos yimaada jawiga cadaadiska sare.
Iska caabbinta daxalka: Qaybaha daawaha gaarka ah waxay si wax ku ool ah uga hortagaan warbaahinta wasakhaysan sida hydrogen sulfide iyo carbon dioxide.
Kalsoonida sare: Xakamaynta tayada adag waxay hubisaa in qalabka farsamada iyo isku dhafka kiimikada ee tuubooyinka birta ay la kulmaan heerka GB/T9948.
3. Habka wax-soo-saarka
GB/T9948-2013 tuubooyinka birta ah ee bilaa-xannida ah waxaa lagu soo saaraa rogid kulul iyo sawir qabow (duubid):
Habka duubista kulul: biilka tuubada wareega → kululaynta → daloolin → duubid → cabirida → qaboojinta → toosinta → hubinta tayada → kaydinta.
Habka sawiridda qabow: daloolinta → pickling → sawir qabow → daaweynta kulaylka → toosinta → ogaanshaha cilladaha → calaamadaynta → kaydinta.
Labada habba waxay xaqiijinayaan saxnaanta cabbirka sare, dusha siman iyo sifooyinka farsamada ee ugu fiican ee tuubooyinka birta.
4. Goobaha codsiga
GB/T9948 tuubooyinka dildilaaca batroolka ayaa si weyn loogu isticmaalaa:
Warshadaha kiimikaad: unugga dildilaaca, reactor hydrogenation, qalabka dib-u-habaynta catalytic
Warshadaha sifaynta saliidda: tuubooyinka foornada heerkulka sare leh, kulaylka beddelayaasha, dhuumaha cadaadiska sarreeya
Gaadiidka gaaska dabiiciga ah: U adkaysiga daxalka, tuubooyinka gudbinta gaaska cadaadiska sare leh
Soo saarista kuleyliyaha: Kuleyliyeyaasha saldhigga korantada, nidaamyada dhuumaha kuleyliyaha warshadaha
5. Rajada suuqa
Iyada oo horumarka degdega ah ee warshadaha petrochemical ee gudaha iyo kobaca baahida suuqa caalamiga ah, mugga iibka ee tuubooyinka birta ah ee GB/T9948 ayaa sii kordhaya. Iska caabin heerkul sare ah oo heerkeedu sarreeyo iyo iska caabbinta daxalka ayaa ka dhigaysa walxaha tuubada ee la door bidayo ee meelaha dildilaaca batroolka iyo sifaynta.
6. Ka taxadarida iibsashada iyo isticmaalka
Xulashada walxaha adag: Dooro walxaha GB/T9948 ee ku habboon (sida 12CrMoG, 15CrMoG, iwm.) iyadoo loo eegayo xaaladaha shaqada (heerkulka, cadaadiska, daxalka).
Shahaadada tayada: Hubi in tuubada birta ay buuxiso heerka GB/T9948-2013 oo bixi warbixinta kormeerka qolo saddexaad.
Rakibaadda iyo dayactirka: Ka fogow burburka farsamada inta lagu jiro gaadiidka iyo rakibidda, oo si joogto ah u hubi daxalka dhuumaha iyo xaaladaha cadaadiska.
GB/T9948-2013 tuubooyinka dildilaaca batroolka ayaa noqday doorasho ku habboon petrochemical, sifaynta, gaaska dabiiciga ah iyo warshadaha kale sababtoo ah faa'iidooyinka caabbinta heerkulka sare, caabbinta cadaadiska sare iyo caabbinta daxalka. Doorashada walxaha ku habboon (sida 12CrMoG, 15CrMoG, iwm.) iyo si adag u raacda heerarka waxay xaqiijin kartaa badbaadada iyo xasilloonida muddada fog ee hawlgalka dhuumaha.
