升降货梯钢管安装有哪些要求？

1、升降货梯http://www.sdsjpt.net/钢管安装时需要检测管子的质量，要查明升降货梯钢管材料、尺度和质量是不是符合规划规则；查看管子外观是不是有严重压扁或曲折；查看管子内外壁表面上是不是有腐蚀表象，外壁是不是有裂纹等缺点。
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、安装升降货梯钢管管道必须按规划图纸或实际测量合理安置，安装时对升降货梯钢管接头、法兰件都要进行质量检测，发现如有缺点，接头、法兰件都禁止运用，应替换，并用火油清洁和用气吹净。
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、升降货梯http://www.sdsjpt.net/钢管安装时对现已酸洗过的管子要用气吹净，对已就位的升降货梯钢管液压阀台、液压泵站、主机、辅机及有关部件的方位应谨慎丈量、力求精确，对接头之间曲折部位较多、形状杂乱的管子要先做一个样板，然后按尺度或样板切开管子。
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.
