PE管材料的发展一般可分为三代
PE管材料的发展一般可分为三代:第一代,相当于现在的PE63以下等级的PE管材料;第二代,相当于现在的PE80级PE管材料;第三代,20世纪80年代出现了被称为“第三代PE管材料”PE100。第二、第三代管材用PE不仅显著增加了长期强度,而且提高检查井钢模具 隔离墩模具 隔离墩钢模具 流水槽模具 U型槽模具 螺杆启闭机 卷扬式启闭机 铜雕佛像 了耐环境应力开裂等性能。在同样使用压力下可以减少壁厚,增加输送截面;在同样壁厚下增加压力,提高输送能力。由于经济效益明显,可应用到直径较大、使用环境较差的场合(如低温地区、海底),因此PE管的应用领域更广阔。
The development of the pipe material can be divided into three generations: the first generation, equivalent to the present PE63 grade pipe material, the second generation, equivalent to the present PE80 grade pipe material; the third generation, in 1980s, is called the "third generation of PE pipe material" PE100. The second and third generation of pipe PE not only significantly increased the long-term strength, but also increased the resistance to environmental stress cracking. Under the same pressure, the wall thickness can be reduced, the conveying cross section will be increased, the pressure will be increased under the same wall thickness, and the conveying capacity can be increased. Because of its obvious economic benefits, it can be applied to occasions with large diameter and poor environment
