卡壓操作步驟(采用液壓工具)：(1)檢查所裝管材與管件符合要求后，進(jìn)行卡壓操作，卡壓前根據(jù)卡壓連接管道規(guī)格選用相應(yīng)規(guī)格的鉗口和卡壓六角形凹槽模具(卡壓凹槽模具根據(jù)不同規(guī)格管道分別選用相應(yīng)規(guī)格模具)。(2)卡壓時把卡壓工具鉗口的六角形環(huán)狀的凹部對準(zhǔn)管件端部裝有環(huán)狀橡膠圈的凸部進(jìn)行卡壓。(3) 卡壓完成后，用**卡壓六角形卡規(guī)檢查卡壓部位尺寸是否到位，當(dāng)卡壓處能完全卡入六角形卡規(guī)時，即為卡壓正確到位，若卡壓后檢驗卡壓不到位則應(yīng)重新進(jìn)行卡壓操作直到卡壓正確到位為止。焊接不銹鋼管件按照制造工藝可以分為：直縫焊接鋼管，埋弧焊接鋼管、板卷對接焊鋼管，焊管熱擴(kuò)鋼管。上海卡壓式不銹鋼管件工藝</p><p

style="text-indent:25px">不銹鋼彎頭擁有很好抗腐蝕性能：1、內(nèi)壁光潔：不銹鋼彎頭管件的內(nèi)壁的光潔度，避免了雜質(zhì)凝聚現(xiàn)象的發(fā)生，是建筑上理想的材料。2、抗拉伸強度高：抗拉伸強度大于530n/㎡要高出一般水管材料2-10倍。3、耐溫性能良好：有的管材在40℃就開始析出有害物質(zhì)，并產(chǎn)生異味；有的管材在溫度用下內(nèi)壁腐蝕速度很快，縮短了管件的使用年限。不銹鋼可以在-270~400℃的溫度下長期工作，性能穩(wěn)定。4、耐磨損性能好：如果管件被水流輕易地侵削，將成為人體健康地危害。不銹鋼管件能經(jīng)受高達(dá)20米/秒流體環(huán)境中運行。5、鈍化作用：水中的PH值、空氣、溶解氧、雜質(zhì)、水處理劑等都可以是管件腐蝕地原因。不銹鋼管件具有一層薄而密的氧化膜，作用在于能夠與氧化劑發(fā)生反應(yīng)，阻止了氧化反應(yīng)地進(jìn)一步發(fā)生。上?？▔菏讲讳P鋼管件工藝</p></p><br
