说 明 A.聚乙烯管易老化,如露天存放宜用篷布等物遮盖,堆放处应远离高热源和火源,制成保温管后,禁止暴晒、骤冷,否则聚乙烯管易开裂,影响产品性能和使用寿命。
B.运输和穿管过程中,应避免野蛮装卸,挂钩过细、过硬、用力过猛,否则易造成聚乙烯管摔坏、划伤或撕裂。
C.管材壁厚可调整,壁厚、颜色可按用户要求生产,因管材壁厚不同,保温层厚度为约数,应按实际厚度计算。
D.与管材配套的支架、塑料塞、两头法兰盘,焊条、焊枪、热缩带等齐全。
E.表中的允许偏差是按CJ/114-2000行业标准制定的。
计算公式为:外径≤400mm时,上下偏差之和=0.1×公称壁厚+0.2
外径≥400mm时,上下偏差之和=0.15×公称壁厚+0.2
