Surface Quality ntawm GB/T 3094-2000 Square Pipe

1. Sab hauv thiab sab nrauv ntawm cov yeeb nkab steel yuav tsum tsis muaj qhov tawg, tawg, nti, thiab delamination. Cov teeb meem no yuav tsum raug tshem tawm tag nrho, thiab qhov tob tshem tawm yuav tsum tsis txhob dhau qhov tsis zoo ntawm qhov nominal phab ntsa thickness. Qhov tseeb phab ntsa thickness ntawm qhov chaw tshem tawm yuav tsum tsis txhob tsawg tshaj li qhov tsawg kawg nkaus tus nqi tso cai los ntawm phab ntsa thickness kam rau ua.
2. Lwm yam kev tsis zoo hauv zos uas tshaj qhov tsis zoo sib txawv ntawm cov phab ntsa tuab yog tso cai kom muaj nyob.
3. Rau cov kav hlau xa mus rau hauv lub xeev ua haujlwm txias, phosphate thiab lubricant txheej txuas nrog lub sijhawm tsim khoom raug tso cai rau sab hauv thiab sab nrauv. Raws li kev pom zoo ntawm ob tog thiab tau teev tseg hauv daim ntawv cog lus, tus neeg muag khoom tuaj yeem tshem tawm cov phosphate thiab lubricant txheej.
4. Cold-drawn welded steel kav yuav tsum tsis txhob muaj lap welding los yog overburning. Sab nrauv weld hlaws ntawm cov yeeb nkab steel yuav tsum tau muab tshem tawm, nrog qhov siab ntxiv tsis tshaj 0.5 hli; lub puab burr ntawm steel yeeb nkab weld yog tso cai kom muaj nyob. Raws li tus neeg yuav khoom thov, thiab tom qab kev pom zoo ntawm ob tog thiab tau teev tseg hauv daim ntawv cog lus, cov kev cai tshwj xeeb tuaj yeem ua rau sab hauv burr.
