Q1: Dab tsi yog qhov txawv ntawm seamless thiab welded kab kav?
A1:Seamless kav yog ua yam tsis muaj vuam, muab cov khoom sib xyaw ua ke thiab lub siab tsis kam. Welded kav yog tsim los ntawm dov steel phiaj thiab vuam lub seam, ua rau lawv muaj txiaj ntsig ntau dua. Seamless kav yog nyiam rau cov ntawv thov siab siab, thaum welded kav yog ntau nyob rau hauv cov txheej txheem loj-diamer. Ob hom yauv ua nruj ua kom muaj kev cia siab. Cov kev xaiv yog nyob ntawm pob nyiaj siv, cov phiaj xwm yuav tsum tau ua, thiab cov yam ntxwv ua kua.
Q2: Dab tsi yog ERW kab yeeb?
A2:ERW (hluav taws xob tiv thaiv welded) kab yeeb nkab yog tsim los ntawm dov hlau coils thiab vuam cov npoo siv hluav taws xob siv hluav taws xob. Nws yog feem ntau siv rau tsawg rau nruab nrab cov ntawv thov. ERW kav yog tus nqi-siv tau thiab muaj nyob rau ntau qhov ntau thiab tsawg. Lawv yauv mus kuaj tsis yog kev ua phem rau Weld ncaj ncees. Cov kav dej no tau siv dav hauv dej, roj, thiab cov roj hluav taws xob.
Q3: Dab tsi yog lsaw kab yeeb nkab?
A3:LSAW tawm (Longitudinal submerged arc welded) yeeb nkab yog tsim los ntawm cov phiaj dabtsi yog khoov hlau thiab vuam raws qhov ntev. Nws yog siv rau cov kab uas loj loj, cov roj kub siab zoo li roj thiab roj kis. Lub submerged arc vuam txheej txheem ua kom ntseeg tau muaj zog, cov nqaws tsis muaj zog. LSAWW kav feem ntau siv nyob rau hauv kev xav tau ib puag ncig xws li Offshore tej yaam num. Lawv tau raug cov tshev ua kom zoo, suav nrog X-ray kuaj.
Q4: Dab tsi yog SSAWaw Kab Yeeb?
A4:Swsaw (kauv subwerged arc welded) yeeb nkab yog tsim los ntawm kev koj hlau vuam hlau strips, tsim ib txoj kev sib tshuam. Nws yog qhov haum rau cov kav dej loj-txoj kab uas loj thiab piling. Tus qauv tsim kom muab cov kev hloov tau zoo thiab kev xa tawm kev ntxhov siab. SSAW Kav yog ib txwm siv nyob rau hauv dej kis thiab cov txheej txheem kev nyab xeeb. Lawv raug kuaj rau Weld Kev Ncaj Ncees thiab qhov sib npaug raug.
Q5: Dab tsi yog clad lossis kab kab hlau?
A5:Clad lossis cov kav dej txi muaj cov txheej corrosion-resistant sab hauv txheej (piv txwv li, stainless hlau lossis alloy) sib raug zoo cov pa yeeb nkab. Lawv tau siv hauv kev txhim kho ib puag ncig zoo li sour roj lossis tshuaj thauj khoom. Cov kab hauv kab mob sab hauv kev xeb thaum tswj lub zog. Cov kav dej no yuav kim dua tab sis txuas ntxiv pipeline lifespan. Lawv xav tau cov txheej txheem welding tshwj xeeb thaum lub teeb nruab.
