Loj Diameter Welded Yeeb Nkab tsim thiab kev siv
Loj Diameter Welded Yeeb Nkab tsim thiab kev siv
Nyob rau hauv thaum ntxov lub sij hawm ntawm lub founding ntawm cov neeg lub koom pheej ntawm Tuam Tshoj, titanium tsuas yog siv nyob rau hauv kev ua tub rog kev lag luam, teej tug mus rau lub teb chaws cov ntaub ntawv tswj lub tswv yim. Nws tsis tau siv rau hauv kev lag luam tshuaj lom neeg kev lag luam kom txog rau thaum xyoo 1970. Txog tam sim no, nws muaj keeb kwm ntau dua 40 xyoo. Titanium, raws li ib qho zoo heev corrosion-resistant structural khoom, tau tsim nws txoj hauj lwm irreplaceable, thiab raws li ib tug zoo tagnrho cov ntaub ntawv nyob rau hauv lub chemical kis pipeline ntawm corrosive media, Loj txoj kab uas hla titanium welded yeeb nkab kuj nyiam ntau thiab ntau xim thiab siv cov khoom siv thiab pipeline designers. .
Raws li peb txhua tus paub, qhov loj-inch titanium welded yeeb nkab feem ntau yog siv rau hauv ib puag ncig corrosive vim nws cov yam ntxwv zoo heev. Thaum cov kua nrog corrosive nruab nrab ntws los ntawm cov yeeb nkab phab ntsa, corrosive nruab nrab yuav me ntsis erode lub puab phab ntsa ntawm cov yeeb nkab welded. Lub corrosion degree ntawm titanium welded yeeb nkab txawv nrog qhov nruab nrab thiab nws cov concentration. Feem ntau, tus nqi corrosion ntawm high concentration nruab nrab hauv tib qhov nruab nrab yog ntau dua li qhov nruab nrab qis concentration. Thaum nruab nrab yog boiling, tus nqi corrosion ntawm Cl uas muaj nruab nrab yog ntau dua li ntawm lwm cov ntsev tov. Tus nqi corrosion ntawm titanium cov khoom nrog siab sab hauv phab ntsa bearing siab yog ntau dua li ntawm cov khoom siv titanium nrog qis sab hauv phab ntsa bearing siab nyob rau hauv tib phab ntsa thickness thiab nruab nrab.
Yog li ntawd, kev pab cuam lub neej ntawm loj-inch titanium welded yeeb nkab feem ntau yog nyob ntawm qhov nruab nrab corrosive, kev pabcuam ib puag ncig thiab cov kabmob siab.
Taw qhia txog cov txheej txheem ntau lawm ntawm txoj kab uas hla loj welded yeeb nkab
Kev tsim cov kab loj loj titanium welded yeeb nkab nyob rau hauv Suav teb yog txwv los ntawm cov txheej txheem kev lag luam thiab kev lag luam me me, thiab cov txheej txheem ntau lawm feem ntau cuam tshuam cov txheej txheem ntau lawm. Txoj kev tsim ntawm cov tuam txhab feem ntau yog siv lub tshuab dabtsi yog khoov, thiab cov txheej txheem ntev yog txwv thiab ovality yog loj. Baoji City Changsheng Titanium tuam txhab txais cov cuab yeej tshwj xeeb thiab tus kheej tsim pwm los nias thiab cov duab, thiab qhov ntev ntawm cov yeeb nkab tuaj yeem ncav cuag 6 meters, nrog me me ovality thiab ncaj. Nyob rau hauv cov nqe lus ntawm vuam, feem ntau manufacturers siv argon arc vuam (TIG) phau ntawv vuam, uas tsis zoo weld tsim, dav weld zoo, thiab tsis sib xws weld reinforcement; Tab sis peb lub tuam txhab txais yuav plasma arc tsis siv neeg vuam (PAW) vuam, uas muaj qhov zoo nkauj weld tsim, zoo weld zoo, thiab cov vuam zoo li qub, uas tau lees paub ntau dua los ntawm cov neeg siv khoom.
Cov txheej txheem ntau lawm yog ua raws li cov kauj ruam hauv qab no:
(1) blanking: ntsuas qhov luaj li cas ntawm lub dav hlau unfolding ntawm titanium yeeb nkab, thiab siv lub tshuab txiav tsis siv neeg los ua blanking, thiab cov khoom siv raw yog dav titanium phaj lossis daim kab xev;
(2) Nias: nyob rau hauv qis tuag, nias los ntawm ob sab ntawm titanium phaj nrog tshwj xeeb khoov khoom, thiab ob sab yog nias rau hauv ib ncig arc;
(3) Kev sib koom ua ke: ib qho kev kho tshwj xeeb ob chav kem roj xovxwm yog siv. Sab siab kab kaw lub welded hlws ris, lub sab sauv siab kem yog welded hlws ris yog tiaj, thiab conveyor siv yog teem rau hauv qab mus thawb lub welded yeeb nkab rau pem hauv ntej;
(4) Spot welding: qhov chaw vuam yog ua nyob rau hauv cov txheej txheem ntawm kev xa cov raj xa dej nrog txoj siv conveyor los ntawm kev siv cov roj tshwj xeeb uas tsim nyog thaum kaw haujlwm;
(5) Vuam: cov khoom siv plasma siab heev yog siv rau vuam. Lub thickness ntawm vuam phaj ntawm cov yeeb nkab welded tuaj yeem ncav cuag 14 hli -18 hli. Tsis tas yuav tsum tau beveling, ib zaug nkag mus, thiab tsim ntawm lub nraub qaum ntawm lub vuam yog zoo nkauj. Qhov tsim nyog tus nqi ntawm X-ray yees duab ntawm lub vuam yog siab li 98 feem pua;
(6) Reshaping: puag ncig thiab ncaj cov yeeb nkab welded nrog cov roj tshwj xeeb xovxwm thiab txhawb kev kho pwm;
(7) Kev ntsuam xyuas tsis zoo: cov pob qij txha yuav tsum tau sim raws li qhov xav tau.
Daim ntawv thov ntawm Loj Diameter Welded Pipe
Titanium welded yeeb nkab yog thawj zaug siv nyob rau hauv lub aerospace teb vim hais tias ntawm nws lub zog tshwj xeeb. Nws tuaj yeem tsis tsuas yog txo qhov hnyav ntawm lub dav hlau, tab sis kuj ua rau lub neej ua haujlwm ntev thiab txo lub sijhawm txij nkawm.
Nyob rau hauv thaum ntxov 20th caug xyoo, pej xeem kev lag luam ntawm titanium cov ntaub ntawv thiab cov khoom raug tsim. Loj txoj kab uas hla titanium welded yeeb nkab tau dav siv nyob rau hauv petrochemical, ntsev ua, tshuaj thiab lwm yam lag luam vim nws zoo heev corrosion kuj thiab thermal conductivity.
Nrog rau txoj kev loj hlob sai ntawm kev lag luam niaj hnub no, ib puag ncig ntuj thiab cov khoom siv dej tau ua rau muaj kuab lom heev, uas ua rau tooj liab thiab tooj liab alloy kav thiab stainless hlau kav, uas yog Ameslikas zoo heev nyob rau hauv cov dej ntshiab thiab huv seawater, nws yuav ua rau corrosion loj heev. Raws li kev hloov pauv rau lwm cov ntaub ntawv hlau, kev ua haujlwm siab, kev tiv thaiv ib puag ncig thiab txuag hluav taws xob loj-inch titanium welded kav tau siv rau hauv seawater desalination, dej phwj tuaj kho thiab lwm yam khoom siv.
Txawm hais tias tus nqi ntawm qhov loj-inch titanium welded yeeb nkab yog me ntsis siab dua, kev pab cuam lub neej ntawm tag nrho cov titanium yeeb nkab tau zoo heev, kev kaw thiab tu cov nqi raug txo, thiab ib puag ncig muaj kuab paug me me, uas ua tau raws li tag nrho cov kev cai ntawm lub teb chaws tam sim no. kev tsim kho lub zog-txuag thiab ib puag ncig-phooj ywg zej zog.
Tsis tas li ntawd, tus nqi ntawm qhov loj-inch titanium welded yeeb nkab yog 40 feem pua - 60 feem pua qis dua qhov seamless titanium yeeb nkab ntawm tib cov specification, uas zoo heev txo tus nqi nkag ntawm cov neeg siv kawg.
