                JDG管壁厚度有具体要求吗

                发布时间:2020/4/15 17:52:54

                  目前广泛使用的JDG管,直接代★替了SC的传统管与PVC管的〖连接方式,作为一种新型的管道,市场选择越来越多,许多小厂家在生』产JDG管时,导致越来越多的角落,扰乱市场,下面介绍JDG的壁厚规范。

                  根据国家标准规【范:0.1中所示承插紧型「钢导管导线及管道施工及验收规范CECS U 120-2007 a,JDG承插紧型钢导管除Φ16GB壁厚外为1.5mm,20,25,32,ΦΦΦΦ40,50GBΦ壁厚为1.6mm,允许▆厚度偏差为:+/-0.15 mm。

                  选择JDG管生╲产厂家应注意的事项:

                  1.选择ㄨ较为正规的JDG管生产厂家,以确保您购买№的JDG金属螺纹管在质量上更好,而且在JDG管价格上会相对便宜,也能得到更好的售后服务。

                  2.检查管子¤表面有无锈蚀、黑点、裂纹、弯曲等现象。

                  3.测卐试管子的长度、厚度和口径是否符合标准。

                  4.采购JDG管,要求JDG管生产厂家提供产品试验报告、合格证、出厂合格证等证明文件。
