3PE防腐钢管标准有何要求及价格变动

2018-01-14

3PE防腐钢管标准为SY/T0413-2002标准、DIN30670-1991标准,他们分别对3PE防腐钢管做出了不同要求。

一、3PE防腐钢管标准

SY/T0413-2002标准主要规范聚乙烯与高密度聚乙烯为主,维卡软化点定为不小于110℃,SY/T0413-2002将3PE防腐层的剥离强度、抗冲击的指标大幅提高,并明确规定了据一些专用料炭黑含量,保证了3PE防腐层的机械强度和耐候性能,并加大了补口剥离强度(即热缩套、热缩带的对底漆钢的剥离强度)抽测频次。

DIN30670-1991标准属于德国标准,主要规范外防腐层的厚度按以低、中密度聚乙烯为主,极大地提高了3PE防腐层的抗冲击强度。
