    Maareynteena aadka u wanaagsan, awood farsamo oo awood leh iyo farsamo nidaamin tayo sare leh, waxaan sii wadeynaa inaan siino macaamiisheena qiimo macquul ah oo la isku halleyn karo, heerar macquul ah iyo adeegyo heer sare ah. We goal at being surely one of your most trustworthy partners and earning your happiness for Alloy Seamless Steel Pipe for High Pressure Boiler, Ku soo dhawoow macaamiisha caalamka si ay noogula soo xiriiraan ganacsiga iyo iskaashiga muddada dheer. Waxaan noqon doonaa lamaanahaaga iyo alaab-qeybiyahaaga lagu kalsoon yahay. Shirkaddayadu waa alaab-qeybiye caalami ah oo ku saabsan badeecadaha noocaan ah. Waxaan bixinaa xulasho cajiib ah oo xalal tayo sare leh. Hadafkayagu waa inaan kugu faraxno ururintayada alaabta maskaxda leh ee gaarka ah anagoo bixinayna qiimo iyo adeeg aad u wanaagsan. Hadafkayagu waa sahlan yahay: Si aan u siino badeecadaha iyo adeegga ugu fiican macaamiisheena qiimaha ugu hooseeya ee suurtogalka ah.

    Kuleyliyaha warshadda korantada alaabta tuubooyinka ugu muhiimsan ee sida caadiga ah loo isticmaalo 15 crmog15 crmog waa 15 crmo birta birta ah ee birta ah ee birta ah, waa nooc ka mid ah birta qaab dhismeedka hoose ee alloy, inta badan waxay ku habboon tahay xisaabinta heerkulka derbiga kama badna 550 ℃ cadaadis sare iyo awood cadaadis sare kuleyliyaha saldhigga tuubada uumiga ugu weyn. Heerka birta ee heerka qaranka GB5310-2017, ee bixinta caadiga ah ee 15 crmog birta daaweynta kulaylka si faahfaahsan.

    Sababtoo ah ku darida walxaha alloy, iyo xisaabinta kaarboonka birta ee u dhiganta CE 0.43 ~ 0.63, waxay muujineysaa alxanka birta 15 crmog si aad ah uga sii dareysa 20 g birta. Si fudud u muuqda dildilaaca qabow alxanka, dib u kululaynta dildilaaca iyo xanaaqa xanaaqa, iwm. Guud ahaan, xaaladaha isku midka ah ee xoogga 15 crmog, qallafsanaanta iyo qalabka kale ee farsamada ayaa ka fiican kan 20 g, marka lagu daro, ku-darka curiyaha Cr si loo hagaajiyo oksaydhka iska caabinta walxaha, ku darida Mo element si loo hagaajiyo xoogga kulaylka ee walxaha, sidaas darteed, 15 crmog birta kuleyliyaha warshadda korontada tuubooyinka ugu weyn ee loo isticmaalo xaalad heerkul sare, oo ku salaysan Shuruudaha waxqabadka makaanikada, isla mar ahaantaana waxay leeyihiin iska caabin oksaydh oo xoog leh oo ku filan iyo caabbinta kulaylka. Sida nooc ka mid ah birta kulaylka u adkeysata, cabbirka luulka 15 crmog wajiga microstructure ee ferrite iyo pearlite, muddada dheer ee xaaladaha heerkulka sare ee la isticmaalo waxay soo saari doontaa spheroidization pearlite. Marka loo eego DL/T787-2001 dhirta tamarta dhuxusha leh ee leh 15 crmo pearlitic steel heerarka rating, marka loo eego jilayaasha ururka spheroidization pearlite heerka spheroidizing waxaa loo qaybin karaa heerarka 1 ilaa 5, iyadoo la kordhinayo heerka spheroidizing, 15 Guryaha farsamada crmog iyo kuwa kulaylka ee birta ayaa hoos u dhacda.

    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.
