Wershada Si Toos Ah U Keenta Tuubbada Kuleyliyaha/ Dhuumaha Cadaadiska Sare
Sida caadiga ah waxaan si fudud u buuxin karnaa macaamiisheena ixtiraamka leh oo leh tayo sare oo aad u wanaagsan, qiimo aad u fiican iyo taageero aad u fiican sababtoo ah waxaan ahayn khabiiro badan oo aad u dadaal badan oo aan u samayno hab kharash-ku-ool ah alaabta tuubooyinka. Waxaan si diiran u soo dhawaynaynaa saaxiibo ka kala socda qaybaha kala duwan ee bulshada inay nala shaqeeyaan.
Tianjin Sanon Steel Pipe Co., Ltd had iyo jeer waa ku saabsan tayada sida aasaaska shirkadda, raadinaya horumarinta via heerka sare ee kalsoonida, u hoggaansamaan heerka maamulka tayada ISO si adag, abuurista sare-sare shirkad by ruuxa horumar-calaamad daacadnimo iyo rajo.
Fadlan ogow in kasta oo kuleyliyaha aan waxba tarayn ay ku sameeyaan geeddi-socod kulul, laakiin haddii aad u baahan tahay qeexid gaar ah iyo hanti farsamo oo gaar ah, waxay ku dari kartaa habka qabow duuban. Caadi ahaan, tuubada duuban ee qabow waxay leedahay saxnaanta cabbirka sare iyo dhammaadka dusha sare, inta badan waxaa loo isticmaalaa qaab dhismeedka makaanikada iyo qalabka hawo-biyoodka. Tuubbada duuban ee qabow waxay gaari kartaa 6mm OD iyo 0.25mm WT.
Sababtoo ah habka duuban qabowgu waa habayn qoto dheer, sidaas darteed waxaa jiri doona kharash dheeraad ah, laakiin macnaheedu maaha in tuubada duuban qabow ay ka fiican tahay tuubada duuban ee kulul. Qabow duuban wuxuu leeyahay xawaare samaynta degdega ah, iyo barta wax-soo-saarka birta ayaa kor loo qaadaa sababtoo ah qallafsanaanta balaastiga weyn; Laakin sababta oo ah tuubooyinka qabow ee duuban ee bilaa-xaraxa ah ayaa lagu giringiriyey hoos heerkulka recrystallization, sidaas darteed waxaa jiri doona cadaadis badan oo haraaga ah gudaha tuubada, waxay si lama filaan ah u saameyn doontaa sifooyinka birta guud ahaan iyo qayb ahaan.
The applciation of qabow giringiriyey tubada bilaa turub inta badan loo isticmaalo sida: qaab-dhismeedka, tuubbada gaarsiinta dareere, tuubada kululeeyaha cadaadis hoose iyo dhexdhexaad ah, tuubada kululeeyaha cadaadis sare, qalabka bacriminta leh tuubo cadaadis sare, tuubada dildilaaca batroolka, tuubbada qodista juqraafi, tuubbada qodista xudunta dheeman, Tuubbada qodista saliidda, kaarboonka birta tuubbada ee maraakiibta, baabuurka badh - tuubbada gacan-gacmeedka tuubbada, tuubbada cadaadiska sare ee matoorada naaftada, tuubooyinka dhoobada ah ee hawo-mareenka iyo pneumatic-ka, tuubo qabow oo duuban ama qabow duuban dhismaha, tuubooyinka birta ah ee aan sinnayn ee gaadiidka dareeraha ah iyo wixii la mid ah.

Codsiga
Waxaa inta badan loo isticmaalaa in lagu sameeyo bir qaab dhismeedka kaarboon oo tayo sare leh, birta qaab dhismeedka daawaha ah iyo birta kulaylka u adkeysi la'aanta ah ee tuubooyinka birta ee cadaadiska sare iyo ka sarreeya tubooyinka kululeeyaha uumiga.
Inta badan loo isticmaalo cadaadiska sare iyo adeega heerkulka sare ee kuleyliyaha (tuubo kululeeyaha, tuubada dib u kululeeyaha, tuubada hagaha hawada, tuubada ugu weyn ee kululeeyaha cadaadiska sare iyo ultra sare). Marka la eego ficilka gaaska qiiqa heerkulkiisu sarreeyo iyo uumiga biyaha, tuubada ayaa oxidized oo qudhmi doonta. Waxaa loo baahan yahay in tuubada birta ay leedahay adkeysi sare, iska caabin sare oo oksaydhka iyo daxalka, iyo xasilloonida qaabdhismeedka wanaagsan.

Marka laga reebo darajooyinka Q345A iyo Q345B, birta waa in ay ka kooban tahay ugu yaraan mid ka mid ah walxaha badarka la safeeyey ee Al, Nb, V, iyo Ti. Marka loo eego baahiyaha, alaab-qeybiyuhu wuxuu ku dari karaa hal ama in ka badan oo walxo hadhuudh ah oo la safeeyey, qiimaha ugu sarreeya waa inuu buuxiyo shuruudaha miiska. Marka la isku daro, Nb + V + Ti <0.22% °Q345, Q390, Q420 iyo Q46O, Mo + Cr <0.30% in ka badan 0.30%; marka ay u baahan tahay in lagu daro, nuxurkeedu waa in uu buuxiyo shuruudaha shaxda ama waxaa go'aaminaya alaab-qeybiyaha iyo iibsadaha iyada oo la tashanayo. aan la fulin. Haddii Al, Nb, V, Ti iyo walxo kale oo alloy ah oo leh hagaajinta nitrogen lagu daro birta, nuxurka nitrogen ma xaddidna. Nuxurka hagaajinta nitrogen waa in lagu qeexaa shahaadada tayada.

Dhererka:
Dhererka caadiga ah ee tuubooyinka birta waa 4 000 mm ~ 12 000 mm. Ka dib markii la tashaday alaab-qeybiyaha iyo iibsadaha, oo buuxi qandaraaska, waxaa la geyn karaa tuubooyinka birta oo dhererkoodu ka weyn yahay 12 000 mm ama ka gaaban I 000 mm laakiin aan ka gaabanayn 3 000 mm; dhererka gaaban Tirada tuubooyinka birta ee ka yar 4,000 mm laakiin aan ka yarayn 3,000 mm waa in aanay ka badnayn 5% tirada guud ee tuubooyinka birta ee la keenay.
Miisaanka gaarsiinta:
Marka tuubada birta la keeno iyadoo loo eegayo dhexroorka dibadda ee magaca iyo dhumucda derbiga magacaaban ama dhexroorka gudaha iyo dhumucda derbiga magacaaban, tuubada birta waxaa la geeyaa iyadoo loo eegayo miisaanka dhabta ah. Waxa kale oo lagu geyn karaa iyadoo loo eegayo miisaanka aragtida.
Marka tuubada birta la keeno iyadoo loo eegayo dhexroorka sare ee magaca iyo dhumucda gidaarka ugu yar, tuubada birta waxaa la geeyaa iyadoo loo eegayo miisaanka dhabta ah; dhinacyada saadka iyo baahida ayaa ka wada xaajooda. Waxaana lagu tilmaamay heshiiska. Dhuumaha birta sidoo kale waxaa lagu geyn karaa iyadoo loo eegayo miisaanka aragtida.
U dulqaadashada miisaanka:
Marka loo eego shuruudaha iibsadaha, ka dib markii la tashaday alaab-qeybiyaha iyo iibsadaha, iyo qandaraaska, leexinta u dhaxaysa miisaanka dhabta ah iyo miisaanka aragtida ee tuubada birta bixinta waa inay buuxisaa shuruudaha soo socda:
a) Dhuumaha birta ah ee keliga ah: ± 10%;
b) Qayb kasta oo tuubooyinka birta ah oo leh cabbirka ugu yar ee 10 t: ± 7.5%.
Shuruudaha Imtixaanka
Tijaabada Biyo-baxa:
Dhuumaha birta waa in si biyo ah mid mid loo tijaabiyaa. Cadaadiska ugu badan ee tijaabada waa 20 MPa. Cadaadiska tijaabada, wakhtiga xasilinta waa inuusan ka yarayn 10 s, iyo tuubada birta ah waa inaysan daadin.
Ka dib marka isticmaaluhu ogolaado, tijaabada hydraulicka waxa lagu bedeli karaa tijaabinta hadda jirta ama tijaabada dheecaanka birlabeedka.
Tijaabada aan burburin:
Tuubooyinka u baahan baaris dheeraad ah waa in ultrasonically loo baaro mid mid. Ka dib markii gorgortanku u baahan yahay ogolaanshaha dhinaca oo lagu qeexay qandaraaska, imtixaano kale oo aan burburin ayaa lagu dari karaa.
Tijaabada fidsan:
Tuubooyinka leh dhexroorka dibadda ee ka weyn 22 mm waa in la mariyaa tijaabo simi ah. Ma jiro delamination muuqda, baro cad, ama wasakhdu waa inay dhacaan inta lagu jiro tijaabada oo dhan.
Tijaabada Daboolida
Marka loo eego shuruudaha iibsadaha oo lagu sheegay qandaraaska, tuubada birta ee leh dhexroorka dibadda ≤76mm iyo dhumucda derbiga ≤8mm waxaa lagu sameyn karaa tijaabin gubasho. Tijaabada waxaa lagu sameeyay heer kulka qolka iyadoo taper ah 60 °. Daboolida ka dib, heerka ololka ee dhexroorka dibadda waa inuu buuxiyaa shuruudaha miiska soo socda, iyo walxaha tijaabada ah waa inaysan muujin dildilaacyo ama dillaac.
