1、升降貨梯http://www.fnae.cn/鋼管安裝時需要檢測管子的質(zhì)量，要查明升降貨梯鋼管材料、尺度和質(zhì)量是不是符合規(guī)劃規(guī)則；查看管子外觀是不是有嚴(yán)重壓扁或曲折；查看管子內(nèi)外壁表面上是不是有腐蝕表象，外壁是不是有裂紋等缺點。
Need to detect when cargo lifter installation quality steel pipe, steel cargo lifter to identify materials, scale and quality is not consistent with the planning rules; see the exterior of the tube is not a serious crush or tortuous;view on the outer wall surface of the pipe is not corrosive appearance, the outer wall is not a drawback crack.
 
2、安裝升降貨梯鋼管管道必須按規(guī)劃圖紙或?qū)嶋H測量合理安置，安裝時對升降貨梯鋼管接頭、法蘭件都要進(jìn)行質(zhì)量檢測，發(fā)現(xiàn)如有缺點，接頭、法蘭件都禁止運用，應(yīng)替換，并用火油清潔和用氣吹凈。
Steel piping installation cargo lifter must plan drawings or actual measurements reasonable placement of cargo lifter pipe fittings, flanges, parts quality testing should be carried out during installation, if any shortcomings found,fittings, flanges, prohibit the use of parts should be replaced with Oil and gas blowing clean.
 
3、升降貨梯http://www.fnae.cn/鋼管安裝時對現(xiàn)已酸洗過的管子要用氣吹凈，對已就位的升降貨梯鋼管液壓閥臺、液壓泵站、主機、輔機及有關(guān)部件的方位應(yīng)謹(jǐn)慎丈量、力求精確，對接頭之間曲折部位較多、形狀雜亂的管子要先做一個樣板，然后按尺度或樣板切開管子。
Cargo lifter pipe for installation pickled now use gas blow pipe, already in place for the orientation of cargo lifter steel hydraulic valve stations, pump stations, main engine and related components should be carefully measured, and strive to accurately of twists and turns between the joint parts are more messy tube shape to do first a model, and then press the scale or template to cut the pipe.
