1.What yog qhov sib txawv ntawm seamless cov yeeb nkab thiab cov yeeb nkab zoo li cas?
Seamless kav thiab ib txwm muaj (welded) kav txawv txawv feem ntau hauv lawv cov kev tsim khoom thiab cov yam ntxwv. Seamless kav yog tsim los ntawm shaping ib tug steel billet rau hauv lub pas dej hollow mus rau hauv lub raj hollow lossis kos duab, weld-tus qauv weld-dawb. Nyob rau hauv sib piv, cov kav dej ib txwm muaj los ntawm dov tiaj tus hlau mus rau hauv cov nplais cylindrical thiab nplooj ntawm cov kab sib dhos weld. Qhov kev sib txawv ntawm cov kev cuam tshuam rau lawv lub zog, durability, thiab kev siv.
2.Is seamless cov yeeb nkab muaj zog dua li welded?
Hais txog lub zog, seamless kav teb feem ntau muaj ntau cov qauv txheej txheem kev ntseeg ncaj ncees vim tias lawv tsis muaj lub ntsej muag weld, uas qee zaum tuaj yeem yog qhov tsis muaj zog hauv welded kav. Thaum lub siab zoo welded yeeb nkab nrog ib tug zoo tua weld (xws li erw lossis tsis muaj kev phom sij, ua rau lawv nyiam dua hauv kev kub siab lossis muaj kev kub siab.
3.Qhov yog lub hom phiaj ntawm lub yeeb nkab uas tsis yog?
Lub hom phiaj tseem ceeb ntawm cov kav dej seamless yog pab rau cov ntawv thov kev ntseeg tau, muaj zog txaus ntshai, thiab muaj zog sib xws. Lawv feem ntau siv nyob rau hauv kev lag luam xws li roj thiab roj (rau kev thauj khoom hydrocarbons), rau cov raj hluav taws xob (piv txwv li, tsav cov hlau thiab cov tshuab hydraulic). Lawv tsis muaj lub ntsej muag weld ua rau lawv nqa cov ntaub ntawv tsim kev puas tsuaj lossis kev ua haujlwm nyob rau hauv cov kev mob siab uas tsis muaj peev xwm ua tiav.
4.Thaum siv cov yeeb nkab uas tsis yog leej twg?
Seamless kav yog qhov kev xaiv xaiv uas nyiam dua thaum daim ntawv thov cuam tshuam nrog kev kub siab, corrosive kev xav, lossis kev nyab xeeb kev nyab xeeb. Piv txwv li, lawv yog qhov tseem ceeb nyob hauv ntug dej Rigs, Chaw Kho Mob Nuclear, thiab cov cuab yeej siv kho mob uas yog qhov tsim nyog-sab hauv yog qhov tsim nyog. Lawv kuj tseem siv rau cov txheej txheem kev thov yuav tsum tau muaj zog ua kom tsis kam, xws li cov tshuab siv tshuab hnyav lossis tshuab hluav taws xob hnyav.
5.Qhov twg yog qhov tsis zoo ntawm cov kav dej seamless?
Txawm hais tias lawv zoo, cov kav dej seamless tau muaj qhov tsis muaj kev cuam tshuam. Lawv cov txheej txheem tsim khoom yog cov ntau dua thiab lub zog-ua kom muaj zog, ua rau lawv kim dua welded kav dej. Tsis tas li ntawd, ua cov kav dej seamless hauv cov kab uas diameters loj lossis cov duab tshwj xeeb yog cov nyom ntau dua, txo qis lawv qhov loj me. Lawv kuj tseem tuaj yeem hnyav dua qhov tsim nyog rau kev siv cov ntawv thov qis-, ua rau cov khoom tsis tsim nyog thiab cov khib nyiab. Thaum kawg, lawv ntau lawm feem ntau muaj qhov kev cuam tshuam ib puag ncig vim muaj rau cov khoom siv kom muaj rau kev extrusion thiab shaping cov txheej txheem.
