Q1: Tus txheej txheem UOE ua haujlwm li cas rau lsaw kav?
A1:Uoe yuav tsim cov phiaj hlau rau hauv ib tug u-duab (u-ing), tom qab ntawd o-duab (o-ing) ua ntej vuam. Cov yeeb nkab tau nthuav dav (e-ing) kom ua tiav qhov ntev kawg thiab txo qis kev ntxhov siab. Tus txheej txheem no ua kom muaj qhov tseeb siab qhov tseeb rau cov kav dej loj (20-60 ntiv). Uoe kav tau siv dav hauv ntug dej hiav txwv thiab cov raj hluav taws xob siab.
Q2: Dab tsi yog qhov sib txawv ntawm ERW thiab HFW kav?
A2: ERW (Electric Resistance Welded) and HFW (High-Frequency Welded) both use electric current but differ in frequency. HFW employs frequencies >70 Khz kom sov sov-cuam tshuam cov aav (Haz), txhim kho weld zoo. HFW yog qhov zoo tshaj plaws rau cov ntawv thov tseem ceeb li roj thiab roj. Ob txoj hauv kev raug nqi-ua tau zoo rau nruab nrab kav dej.
Q3: Vim li cas cov kav dej seamless uas nyiam dua rau cov ntawv thov siab?
A3:Seamless pipes Tsis muaj Welds, tshem tawm cov ntsiab lus tsis muaj zog thiab ua kom muaj zog txheej txheem. Lawv tuav cov kev ntsuas siab dua (txog li 20,000 psi) thiab kub. Cov ntawv thov tseem ceeb zoo li cov fellores thiab kev ua kom zoo dua cov kav dej seamless. Txawm li cas los xij, lawv kim dua thiab txwv rau cov diameters me me (tsawg dua lossis sib npaug ntawm 24 nti).
Q4: Kev tsim khoom JCO yog dab tsi?
A4:JQE cov ntaub ntawv los ntawm kev nce qib dab tsi los ntawm ib qho J-puab, ces C-puab, ua ntej kaw rau hauv O-puab thiab nthuav dav. Nws raug nqi rau kev ua haujlwm nruab nrab-rau-kab uas diameters (16-56 ntiv). Cov txheej txheem tso cai hloov tau ntau lawm ntawm cov kav hlau tuab-walled. Jese kav tso tawm nrog uoe hauv onshore rajeore.
Q5: Yuav ua li cas cov yeeb nkab tas npaj rau vuam?
A5:Yeeb nkab xaus yog beveled mus rau 30℃kaum sab xis (v-bevel) rau vuam hauv paus hla dhau. Precision Machining ua kom haum rau qhov raug. Qee cov kav dej muaj sab hauv / sab nraud counterbores rau kev sib ncag. Beveling txoj kev muaj xws li milling, sib tsoo, lossis nplaim taws txiav. Tsimnyog kom raug rau kev siv vuam tsis zoo li tsis muaj fusion.
