玻璃钢饮用水管道

RPM管的温度使用范围一般在 ４０ ８０ 之间，若先用特殊树脂其使用温度可达到更高。 RPM管道的比重为１.７ １.９ ，管的环向拉伸强度为３２０MPa,轴向拉伸强度为２３０MPa，与同压力、同管径的其他材质管道比较，RPM管道单位长度、重量约等于钢管的３０ ，约等于钢筋混凝土管的８ ，因此运输安装十分方便，RPM管道每根长度可达１２m，比混凝土管可减少三分之二的接头。 RPM管道内表面非常光滑，糙率系数小，水利系数Ｃ可长期保持在145-150范围内，经测试得到其水流摩阻损失系数f为0.000915，比混凝土管(f=0.00232)和钢管(f=0.00179)能显著减少沿程的流体压力损失 ，提高输送能力２０ 以上。 因此，在输送能力相同时，工程可选用内径较小的RPM管道，从而降低一次性的工程投入，若采用同等内径的管道，RPM管道可比其他材质管道减少压头损失 ，节省泵的功率和能源 约３０ ４０ ，减少长期运行费用。 RPM是非导体，管道的绝缘性好，最适应使用于输电、电信线路密集区和多雷区，RPM管的传热系数很小 ０.２５kcal/m h ，因此管道的保温性好，热损失少。

玻璃钢管道比重小 1.8 2.1g/ 3 强度高 300MPa ，其比强度远大于钢管和铸铁管，由于在管壁中间层加入树脂砂浆，大大提高了管道刚度，适应在各种土壤环境及海底铺设。 玻璃钢管道内表面十分光滑、摩擦阻力小 n 0.0084 ，能明显减少沿程压力损失、增大流量，在相同流量的情况下，可以选用较小的管径或功率较小的输送泵，从而降低了工程初期投资、节约能耗 降低运行成本。 1 直径 DN300 -DN4000. 2 压力等级 0.25 MPa、0.6 MPa、1.0 MPa、1.6 MPa、2.0 MPa、2.5MPa. 3 单根长度 3 m、6 m、9 m、12m. 4 刚度等级 2500N/ 、5000 N/ 、10000 N/. 双 O 型密封圈承插连接、单 O 型密封圈承插连接、对接及承插粘接、法兰连接等.

Wanderlust - Our Seafarer 22 Sailing Adventures
Wanderlust - Our Seafarer 22 Sailing Adventures. Thursday, September 25, 2014. Over night in Cuttyhunk. First I just wanted to apologize for not updating this more often. With 4 active kids there just doesn't seem to be enough hours in the day. The summer went by way to quick and the kids are all back in school. Well all but the baby. The wind was really good. But I do have to be honest, I REALLY hate when the boat lists and wets the. Cuttyhunk itself was pretty cool. Pretty much no cars, and was ver...
