PP-R管作为一种新型的管材

文章出处:本站责任编辑:Admin人气:发表时间:2017/11/23 9:52:45【
 PP-R管作为一种新型的管材,具有以下性能特点:
 
1、节能PP-R管的生产能耗仅为钢管的20%,并且其导热系数低[0.2W/(M.K)],也仅为钢管的1/200,应用于热水系统将大大减少热量损失。
 
 
 
2、耐腐蚀、不结垢、卫生、无毒使用PP-R管可免去使用镀锌钢管所造成的内壁结垢、生锈而引起的水质“二次污染”。由于PP-R组份单纯,基本成份为碳和氢,符合食品卫生规定,无毒,更适合于饮用水输送。
 
3、耐热、耐压、使用寿命长PP-R管的长期使用温度达95℃,短期使用温度可达120℃。在使用温度为70℃,工作压力为1.2MPa条件下,长期连续使用,寿命可达50年以上。
 
4、轻质高强、流体阻力小PP-R管密度仅为金属管的1/8,耐压力试验强度高达5Mpa,且韧性好、耐冲击。由于内壁光滑、不生锈、不结垢,流体阻力小。
