2选择弯管机械ndoyigmyeozuewvjisyxqfmwndnki

全面分析对比弯管机械的类型，选择最佳机械：液压弯管器。使弯管模具管径适满足设计要求，确保弯管后，管道的水平度为1%。kvvcwoaxwxctsejcrlyadifwoxclrt
zlinwgbvnwyqdypqgdfgwj
针对弯管的弧度，用液压弯管机配备的弧度角度尺检测，待每根管道弯毕后，及时用角度尺和塞尺检验，如在偏差范围外即需调整，直至弯管达标。grewtythjntnnfcbjpsubzlgdgrgycmmlqkx

弯管过程中主要进行角度测量，以保证弯管弧度满足设计要求。测量工具的选用，由专业工程师负责，尽量选用测量精度高的测量仪器，并要对测量仪器进行校核。工程师对现场测量人员进行现场指导，正确测量。igrmogdfufyfija

5检查管道长度ugqfgmjjhkiqejimtovytyqlsmkaxbzdkojztofgexlw

确定管道的最佳长度，测量出弯管角度，保证弯管合格率高。qjtcimcuinmynabqpdpxishuzlsayaxykw
zlinwgbvnwyqdypqgdfgwj
由于液压弯管机不能准确测定短管角度，也就无法保证圆弧的准确性，所以为确保弯管质量，选用长管，当短管长度小于液压弯管机两固定点之间的距离时，不得使用，而把它用在其它直管段上，这样即不影响弯管合格率也不浪费材料。wscfecbmdiialvvjna
