Q1: Dab tsi yog qhov sib txawv ntawm cov nqi tsim ntawm hluav taws xob tiv thaiv welded yeeb nkab welded yeeb thiab seamless yeeb nkab?
Cov yeeb nkab ntau lawm ntawm welded yeeb nkab yog {}}% qis dua li ntawm cov yeeb nkab npliag, cov khoom siv kub siv yog 70%); ② Nruam kev sib txuas ua hluav taws xob nrawm tuaj yeem ncav cuag 60m / min (seamless perforation yog {}} m / min); ③ Kev siv hluav taws xob qis (Welded cov yeeb nkab yog li 300 tawm cov yeeb nkab uas yuav tsum tau siv nyiaj ntau ntxiv thaum muaj qhov sib npaug ntawm 168 hli {{{{}
Q2: Nyob rau hauv cov kev mob yuav tsum yog seamless yeeb nkab siv tau es tsis txhob welded yeeb nkab?
① ultra-siab siab mob (xws li cov roj zoo casing p ntau dua lossis sib npaug nrog 110mPA); ② Qhov Kub Kub (Boiler Tube Dav Dav Hlau> 600 degree); ③ muaj zog corrosive kev tshaj tawm (xws li HCL ib puag ncig); ④ Cov roj ua kom muaj zog thauj khoom (xws li aviation hydraulic yeeb); ⑤ Qhov Kev Ua Si Nuclear (yuav tsum muaj cov yeeb nkab tag nrho tsis muaj weld tsis muaj zog dhau los yog qhov sib npaug ntawm kev kho mob welded
Q3: Dab tsi yog qhov zoo ntawm welded kav nyob rau hauv cov nqe lus ntawm qhov tseeb raug?
Cov txheej txheem sab nraud kam kam rau welded pipes tuaj yeem ncav cuag ± 4 9} {{± 0 {{{}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} Phab ntsa tuab ntawm cov khoom siv tsis zoo ntawm welded kav yog ± 7. 5%, thaum ntawd ntawm seamless kav yog ± 12.5%. Qhov no yog vim welded kav siv-dov txias-rolled precision strip hlau, thiab cov sizing chav tsev muaj qhov tseeb ntawm 0.1mm. Lub roundness ntawm welded kav rau tsheb kis tau yog tsawg dua lossis sib npaug rau 0.3mm, deb tshaj li qib ntawm seamless kav. Nyias-walled kav (xws li Δ=1 mm mm) tuaj yeem yuav luag tsuas yog tsim los ntawm cov txheej txheem yeeb nkab welded.
Q4: Yuav ua li cas txoj kev ua pauj tau txhim kho kev ua tau zoo ntawm cov kav dej welded?
Los ntawm kev kho cua sov tag nrho (xws li 900℃ib txwm ua)}} thiab anisotropy piv yog txo qis rau hauv qab1.1. japd welded kav dej mus txog rau kev ua kom tob tob-pipelines {{8 8}}
Q5: Yuav Welded Pipes Hloov Seamless Pipes Yav Tom Ntej?
Hauv kev sib tw ntawm 508mm, kev lag luam sib koom ua ke tau tshaj li 80 xyoo, xws li cov roj av uas tuab ({} Qhia: ① Lub zog ntawm welded kav yog txhim kho los ntawm TMCP cov txheej txheem; ② Qhov yeeb nkab seamless siv oblique dov perforation +}} Nws yog qhov kev sib raug zoo heev yuav nyob ib puag ncig 7: 3 hauv 2030.
