** 1. Tuaj yeem erw cov yeeb nkab raug seamless? **
Tsis yog, los ntawm kev txhais, ib qho ERW (hluav taws xob tiv thaiv welded) yeeb nkab tsis tau seamless. Qhov tseem ceeb sib txawv lus dag nyob hauv kev tsim khoom. Seamless kav yog tsim los ntawm cov khoom ntim khoom ntawm cov hlau uas yog chob thiab dov mus rau hauv raj hollow tsis muaj welds. ERW kav, ntawm qhov tod tes, yog tsim los ntawm dov lub steel chev thiab tom qab ntawd siv hluav taws xob ua ke cov npoo ua ke, sib sau ua ke ntev weld seam. Yog li ntawd, muaj qhov no Weld Seam yog dab tsi tus xeeb ntxwv ib qho erw yeeb nkab.
** 2. Cov txiaj ntsig ntawm ERW yog dab tsi? **
ERW kav muab ntau cov txiaj ntsig tseem ceeb:
* ** Tus nqi {- ua tau zoo: ** Cov txheej txheem ERW yog qhov ua tau zoo thiab xav tau tsawg zog piv, ua cov kav dej ntau dua kev lag luam.
* ** Phab ntsa tuab: ** Vim tias lawv tau ua los ntawm Rolled steel ib daim, erw kav muaj cov phab ntsa zoo nkauj ib puag ncig lawv txoj kab ncig.
* ** Lawv cov txheej txheem zoo raug: ** Lawv cov kev tswj hwm zoo dua hla txoj taub thiab phab ntsa tuab, uas yog qhov tseem ceeb rau ntau cov kev siv tshuab thiab tshuab kho tshuab.
* ** Cov npoo du ua tiav: ** Cov khoom siv raw (skelp) muaj qhov chaw du, uas ua rau muaj yeeb nkab nrog kev ua tiav sab hauv thiab sab nraud.
* ** Muaj nyob rau hauv ntev ntev: ** Lawv tuaj yeem tsim nyob rau hauv tas mus li ntev, uas txo tus naj npawb ntawm cov pob qij txha xav tau nyob rau hauv ib tug raj dej.
** 3. Koj puas tuaj yeem khoov ib lub nkoj erw? **
Yog lawm, koj tuaj yeem khoov ib lub raj dej ERW, tab sis nws yuav tsum ua tib zoo xav txog. Weld seam tuaj yeem yog ib qho kev tsis muaj zog thaum lub sijhawm muaj cov txheej txheem. Rau kev ua tiav dabtsi yog:
* Qhov zoo ntawm Weld yuav tsum muaj siab, tsis muaj qhov tsis xws luag lossis tsis muaj kev sib cav.
* Nws feem ntau pom zoo rau Orient Weld Seam ntawm lub neutral axis ntawm bend (sab ntawm lub raj) kom tsis txhob tso nws siab tshaj plaws los yog compression.
* Cov txheej txheem dabtsi yog (piv txwv li, Mandrel khoov, teb cov kab laum khoov) yuav tsum tau tswj hwm wrinkling los yog flottening ntawm lub raj. Bent kom zoo, lub siab- Zoo ERW Tube yog haum rau ntau cov kev siv tshuab thiab tshuab kho tshuab.
** 4. Yog erw yeeb nkab galvanized? **
ERW cov yeeb nkab tsis muaj keeb Galvanized. "ERW" piav qhia txog kev vuam txoj kev vuam siv los ua cov yeeb nkab. Galvanization yog ib qho txheej txheem thib ob uas cov txheej tiv thaiv ntawm zinc yog siv rau cov yeeb nkab steel los tiv thaiv corrosion. Yog li ntawd, ib qho ntawv pov thawj ERW tuaj yeem muab tau raws li dub (tsis muaj peev xwm) lossis nws tuaj yeem xa rau Galvanizing tom qab nws tsim. Nws yog ib qho uas pom Galvanized ERW hauv kev ua lag luam rau cov ntawv thov ua kom xeb, xws li fencing, tes, thiab dej kab.
** 5. Yuav ua li cas xyuas ERW cov yeeb nkab? **
Xyuas ERW cov yeeb nkab zoo cuam tshuam nrog ntau txoj kev:
* ** Xyuas Xyuas: ** Saib seb puas muaj qhov tsis xws luag zoo li dents, khawb, lossis tsis sib xws hauv Weld hlaws.
* ** Kev kuaj xyuas qhov ntev: ** Siv calipers thiab daim kab xev ntsuas kom paub cov taub sab nraud, phab ntsa tuab, thiab ntev ua tau raws li cov lus qhia tshwj xeeb.
* ** WELD Seam Tshuaj Tiv Thaiv: ** Qhov no tseem ceeb heev. Tsis - Txoj Kev Kuaj (NDT) tau siv, xws li kev sim ultrasonic, txhawm rau txhawm rau ntsuas cov kab nrib pleb lossis tsis muaj kev sib tsoo hauv Weld.
* ** Kev ntsuam xyuas cov tshuaj thiab kev siv tshuab: ** Ua qauv rau ib sim tshuaj kom paub tseeb tias muaj zog los xyuas cov tshuaj lom neeg kom ntseeg tau tias cov khoom siv cov khoom siv.
* ** Cov yeeb nkab muaj zog: ** Cov yeeb nkab puv nrog dej thiab nias rau qib tshwj xeeb los kuaj xyuas nws lub zog thiab kom nws tsis txhob xau. Nov yog kev kuaj mob rau cov kav dej rau cov kav xa mus rau kev pabcuam siab.
