PE管焊接中容易出现的问题及解决途径

1、热熔管件和电熔管件哪种更好? 两者各有优点,但在欧洲国家电熔管件一般情况是在抢修或无法放置热熔焊机时采用。国际要求热熔对接焊接时,两管管径对准偏差不能超过管径的10%,故小口径(Dn≤D90)难以掌握。另外大口径的电熔管件造价太高造成了目前市场上小口径多用电熔连接,大口径多用热熔连接。 2、电熔管件的观察孔焊接后冒出长度怎样调整,多长为佳? 在管件壁厚一定的情况下可由电阻丝的布设深度来调整,观察孔的冒出长度也可侧面反映布线情况的好坏。冒出过长说明布线过深,过短说明布线过浅。一般观察孔冒出只作为焊接完成的标志,无具体要求,但正常冒出5mm~6mm为宜。 3、电熔管件焊制时短路、暴沸由何引起,怎样预防? 最经常的原因是管子在管件内的定位不正确;插入深度未到位,轴向未对中等;或管子与管件尺寸配合出现较大偏差,如管子的不圆度严重超标。另外还可能是由于电熔管件和管 ...
