S235JR Welded Pipe Description

S235 JR Spiral steel yeeb nkab yog ib qho kauv steel yeeb nkab ua los ntawm kev khoov strips los yog coils nyob rau hauv ib tug kauv zoo thiab welding lub puab thiab sab seams siv ob-sided submerged arc tsis siv neeg vuam. Nws tuaj yeem siv dav hauv dej, hluav taws xob, tshuaj lom neeg kev lag luam, thiab lwm yam. Cov txheej txheem welding ntawm kauv welded yeeb nkab adopts submerged arc vuam. Qhov no yog ib txoj kev vuam uas siv hluav taws xob arc ua qhov cua sov. Lub arc hlawv nyob rau hauv lub npog ntawm granular fusible flux, thiab cov flux melts los ua ib tug slag npuas, uas nyob ib ncig ntawm lub pas dej ua kua molten thiaj li hais tias lub teeb arc tsis raug. Cov hlau electrode siv yog tsis tu ncua pub liab qab vuam hlau.
